+suggested by Andrew Morton in http://lkml.org/lkml/2007/4/11/263.
+
+Per cgroup statistics infrastructure re-uses code from the taskstats
+interface. A new set of cgroup operations are registered with commands

+extend per cgroup statistics, by adding members to the cgroupstats
+structure.
+
+The current model for cgroupstats is a pull, a push model (to post
+statistics on interesting events), should be very easy to add. Currently

+user space.

+about tasks blocked on I/O. If CONFIG_TASK_DELAY_ACCT is disabled, this

+1. Control Groups
+==========
+
+1.1 What are cgroups ?
+----------------------
+
+Control Groups provide a mechanism for aggregating/partitioning sets of
+tasks, and all their future children, into hierarchical groups with
+specialized behaviour.
+
+Definitions:
+
+A *cgroup* associates a set of tasks with a set of parameters for one
+or more subsystems.
+
+A *subsystem* is a module that makes use of the task grouping
+facilities provided by cgroups to treat groups of tasks in
+particular ways. A subsystem is typically a "resource controller" that
+schedules a resource or applies per-cgroup limits, but it may be
+anything that wants to act on a group of processes, e.g. a
+virtualization subsystem.
+
+A *hierarchy* is a set of cgroups arranged in a tree, such that
+every task in the system is in exactly one of the cgroups in the
+hierarchy, and a set of subsystems; each subsystem has system-specific
+state attached to each cgroup in the hierarchy. Each hierarchy has
+an instance of the cgroup virtual filesystem associated with it.
+
+At any one time there may be multiple active hierachies of task
+cgroups. Each hierarchy is a partition of all tasks in the system.
+
+User level code may create and destroy cgroups by name in an
+instance of the cgroup virtual file system, specify and query to
+which cgroup a task is assigned, and list the task pids assigned to
+a cgroup. Those creations and assignments only affect the hierarchy
+associated with that instance of the cgroup file system.
+
+On their own, the only use for cgroups is for simple job
+tracking. The intention is that other subsystems hook into the generic
+cgroup support to provide new attributes for cgroups, such as
+accounting/limiting the resources which processes in a cgroup can
+access. For example, cpusets (see Documentation/cpusets.txt) allows
+you to associate a set of CPUs and a set of memory nodes with the
+tasks in each cgroup.
+
+1.2 Why are cgroups needed ?
+----------------------------
+
+There are multiple efforts to provide process aggregations in the
+Linux kernel, mainly for resource tracking purposes. Such efforts
+include cpusets, CKRM/ResGroups, UserBeanCounters, and virtual server
+namespaces. These all require the basic notion of a
+grouping/partitioning of processes, with newly forked processes ending
+in the same group (cgroup) as their parent process.
+
+The kernel cgroup patch provides the minimum essential kernel
+mechanisms required to efficiently implement such groups. It has
+minimal impact on the system fast paths, and provides hooks for
+specific subsystems such as cpusets to provide additional behaviour as
+desired.
+
+Multiple hierarchy support is provided to allow for situations where
+the division of tasks into cgroups is distinctly different for
+different subsystems - having parallel hierarchies allows each
+hierarchy to be a natural division of tasks, without having to handle
+complex combinations of tasks that would be present if several
+unrelated subsystems needed to be forced into the same tree of
+cgroups.
+
+At one extreme, each resource controller or subsystem could be in a
+separate hierarchy; at the other extreme, all subsystems
+would be attached to the same hierarchy.
+
+As an example of a scenario (originally proposed by vatsa@in.ibm.com)
+that can benefit from multiple hierarchies, consider a large
+university server with various users - students, professors, system
+tasks etc. The resource planning for this server could be along the
+following lines:
+
+ CPU : Top cpuset
+ / \
+ CPUSet1 CPUSet2
+ | |
+ (Profs) (Students)
+
+ In addition (system tasks) are attached to topcpuset (so
+ that they can run anywhere) with a limit of 20%
+
+ Memory : Professors (50%), students (30%), system (20%)
+
+ Disk : Prof (50%), students (30%), system (20%)
+
+ Network : WWW browsing (20%), Network File System (60%), others (20%)
+ / \
+ Prof (15%) students (5%)
+
+Browsers like firefox/lynx go into the WWW network class, while (k)nfsd go
+into NFS network class.
+
+At the same time firefox/lynx will share an appropriate CPU/Memory class
+depending on who launched it (prof/student).
+
+With the ability to classify tasks differently for different resources
+(by putting those resource subsystems in different hierarchies) then
+the admin can easily set up a script which receives exec notifications
+and depending on who is launching the browser he can
+
+ # echo browser_pid > /mnt/<restype>/<userclass>/tasks
+
+With only a single hierarchy, he now would potentially have to create
+a separate cgroup for every browser launched and associate it with
+approp network and other resource class. This may lead to
+proliferation of such cgroups.
+
+Also lets say that the administrator would like to give enhanced network
+access temporarily to a student's browser (since it is night and the user
+wants to do online gaming :) OR give one of the students simulation
+apps enhanced CPU power,
+
+With ability to write pids directly to resource classes, its just a
+matter of :
+
+ # echo pid > /mnt/network/<new_class>/tasks
+ (after some time)
+ # echo pid > /mnt/network/<orig_class>/tasks
+
+Without this ability, he would have to split the cgroup into
+multiple separate ones and then associate the new cgroups with the
+new resource classes.
+
+
+
+1.3 How are cgroups implemented ?
+---------------------------------
+
+Control Groups extends the kernel as follows:
+
+ - Each task in the system has a reference-counted pointer to a
+ css_set.
+
+ - A css_set contains a set of reference-counted pointers to
+ cgroup_subsys_state objects, one for each cgroup subsystem
+ registered in the system. There is no direct link from a task to
+ the cgroup of which it's a member in each hierarchy, but this
+ can be determined by following pointers through the
+ cgroup_subsys_state objects. This is because accessing the
+ subsystem state is something that's expected to happen frequently
+ and in performance-critical code, whereas operations that require a
+ task's actual cgroup assignments (in particular, moving between
+ cgroups) are less common. A linked list runs through the cg_list
+ field of each task_struct using the css_set, anchored at
+ css_set->tasks.
+
+ - A cgroup hierarchy filesystem can be mounted for browsing and
+ manipulation from user space.
+
+ - You can list all the tasks (by pid) attached to any cgroup.
+
+The implementation of cgroups requires a few, simple hooks
+into the rest of the kernel, none in performance critical paths:
+
+ - in init/main.c, to initialize the root cgroups and initial
+ css_set at system boot.
+
+ - in fork and exit, to attach and detach a task from its css_set.
+
+In addition a new file system, of type "cgroup" may be mounted, to
+enable browsing and modifying the cgroups presently known to the
+kernel. When mounting a cgroup hierarchy, you may specify a
+comma-separated list of subsystems to mount as the filesystem mount
+options. By default, mounting the cgroup filesystem attempts to
+mount a hierarchy containing all registered subsystems.
+
+If an active hierarchy with exactly the same set of subsystems already
+exists, it will be reused for the new mount. If no existing hierarchy
+matches, and any of the requested subsystems are in use in an existing
+hierarchy, the mount will fail with -EBUSY. Otherwise, a new hierarchy
+is activated, associated with the requested subsystems.
+
+It's not currently possible to bind a new subsystem to an active
+cgroup hierarchy, or to unbind a subsystem from an active cgroup
+hierarchy. This may be possible in future, but is fraught with nasty
+error-recovery issues.
+
+When a cgroup filesystem is unmounted, if there are any
+child cgroups created below the top-level cgroup, that hierarchy
+will remain active even though unmounted; if there are no
+child cgroups then the hierarchy will be deactivated.
+
+No new system calls are added for cgroups - all support for
+querying and modifying cgroups is via this cgroup file system.
+
+Each task under /proc has an added file named 'cgroup' displaying,
+for each active hierarchy, the subsystem names and the cgroup name
+as the path relative to the root of the cgroup file system.
+
+Each cgroup is represented by a directory in the cgroup file system
+containing the following files describing that cgroup:
+
+ - tasks: list of tasks (by pid) attached to that cgroup
+ - notify_on_release flag: run /sbin/cgroup_release_agent on exit?
+
+Other subsystems such as cpusets may add additional files in each
+cgroup dir
+
+New cgroups are created using the mkdir system call or shell
+command. The properties of a cgroup, such as its flags, are
+modified by writing to the appropriate file in that cgroups
+directory, as listed above.
+
+The named hierarchical structure of nested cgroups allows partitioning
+a large system into nested, dynamically changeable, "soft-partitions".
+
+The attachment of each task, automatically inherited at fork by any
+children of that task, to a cgroup allows organizing the work load
+on a system into related sets of tasks. A task may be re-attached to
+any other cgroup, if allowed by the permissions on the necessary
+cgroup file system directories.
+
+When a task is moved from one cgroup to another, it gets a new
+css_set pointer - if there's an already existing css_set with the
+desired collection of cgroups then that group is reused, else a new
+css_set is allocated. Note that the current implementation uses a
+linear search to locate an appropriate existing css_set, so isn't
+very efficient. A future version will use a hash table for better
+performance.
+
+To allow access from a cgroup to the css_sets (and hence tasks)
+that comprise it, a set of cg_cgroup_link objects form a lattice;
+each cg_cgroup_link is linked into a list of cg_cgroup_links for
+a single cgroup on its cont_link_list field, and a list of
+cg_cgroup_links for a single css_set on its cg_link_list.
+
+Thus the set of tasks in a cgroup can be listed by iterating over
+each css_set that references the cgroup, and sub-iterating over
+each css_set's task set.
+
+The use of a Linux virtual file system (vfs) to represent the
+cgroup hierarchy provides for a familiar permission and name space
+for cgroups, with a minimum of additional kernel code.
+
+1.4 What does notify_on_release do ?
+------------------------------------
+
+*** notify_on_release is disabled in the current patch set. It will be
+*** reactivated in a future patch in a less-intrusive manner
+
+If the notify_on_release flag is enabled (1) in a cgroup, then
+whenever the last task in the cgroup leaves (exits or attaches to
+some other cgroup) and the last child cgroup of that cgroup
+is removed, then the kernel runs the command specified by the contents
+of the "release_agent" file in that hierarchy's root directory,
+supplying the pathname (relative to the mount point of the cgroup
+file system) of the abandoned cgroup. This enables automatic
+removal of abandoned cgroups. The default value of
+notify_on_release in the root cgroup at system boot is disabled
+(0). The default value of other cgroups at creation is the current
+value of their parents notify_on_release setting. The default value of
+a cgroup hierarchy's release_agent path is empty.
+
+1.5 How do I use cgroups ?
+--------------------------
+
+To start a new job that is to be contained within a cgroup, using
+the "cpuset" cgroup subsystem, the steps are something like:
+
+ 1) mkdir /dev/cgroup
+ 2) mount -t cgroup -ocpuset cpuset /dev/cgroup
+ 3) Create the new cgroup by doing mkdir's and write's (or echo's) in
+ the /dev/cgroup virtual file system.
+ 4) Start a task that will be the "founding father" of the new job.
+ 5) Attach that task to the new cgroup by writing its pid to the
+ /dev/cgroup tasks file for that cgroup.
+ 6) fork, exec or clone the job tasks from this founding father task.
+
+For example, the following sequence of commands will setup a cgroup
+named "Charlie", containing just CPUs 2 and 3, and Memory Node 1,
+and then start a subshell 'sh' in that cgroup:
+
+ mount -t cgroup cpuset -ocpuset /dev/cgroup
+ cd /dev/cgroup
+ mkdir Charlie
+ cd Charlie
+ /bin/echo 2-3 > cpus
+ /bin/echo 1 > mems
+ /bin/echo $$ > tasks
+ sh
+ # The subshell 'sh' is now running in cgroup Charlie
+ # The next line should display '/Charlie'
+ cat /proc/self/cgroup
+
+2. Usage Examples and Syntax
+============================
+
+2.1 Basic Usage
+---------------
+
+Creating, modifying, using the cgroups can be done through the cgroup
+virtual filesystem.
+
+To mount a cgroup hierarchy will all available subsystems, type:
+# mount -t cgroup xxx /dev/cgroup
+
+The "xxx" is not interpreted by the cgroup code, but will appear in
+/proc/mounts so may be any useful identifying string that you like.
+
+To mount a cgroup hierarchy with just the cpuset and numtasks
+subsystems, type:
+# mount -t cgroup -o cpuset,numtasks hier1 /dev/cgroup
+
+To change the set of subsystems bound to a mounted hierarchy, just
+remount with different options:
+
+# mount -o remount,cpuset,ns /dev/cgroup
+
+Note that changing the set of subsystems is currently only supported
+when the hierarchy consists of a single (root) cgroup. Supporting
+the ability to arbitrarily bind/unbind subsystems from an existing
+cgroup hierarchy is intended to be implemented in the future.
+
+Then under /dev/cgroup you can find a tree that corresponds to the
+tree of the cgroups in the system. For instance, /dev/cgroup
+is the cgroup that holds the whole system.
+
+If you want to create a new cgroup under /dev/cgroup:
+# cd /dev/cgroup
+# mkdir my_cgroup
+
+Now you want to do something with this cgroup.
+# cd my_cgroup
+
+In this directory you can find several files:
+# ls
+notify_on_release release_agent tasks
+(plus whatever files are added by the attached subsystems)
+
+Now attach your shell to this cgroup:
+# /bin/echo $$ > tasks
+
+You can also create cgroups inside your cgroup by using mkdir in this
+directory.
+# mkdir my_sub_cs
+
+To remove a cgroup, just use rmdir:
+# rmdir my_sub_cs
+
+This will fail if the cgroup is in use (has cgroups inside, or
+has processes attached, or is held alive by other subsystem-specific
+reference).
+
+2.2 Attaching processes
+-----------------------
+
+# /bin/echo PID > tasks
+
+Note that it is PID, not PIDs. You can only attach ONE task at a time.
+If you have several tasks to attach, you have to do it one after another:
+
+# /bin/echo PID1 > tasks
+# /bin/echo PID2 > tasks
+ ...
+# /bin/echo PIDn > tasks
+
+3. Kernel API
+=============
+
+3.1 Overview
+------------
+
+Each kernel subsystem that wants to hook into the generic cgroup
+system needs to create a cgroup_subsys object. This contains
+various methods, which are callbacks from the cgroup system, along
+with a subsystem id which will be assigned by the cgroup system.
+
+Other fields in the cgroup_subsys object include:
+
+- subsys_id: a unique array index for the subsystem, indicating which
+ entry in cgroup->subsys[] this subsystem should be
+ managing. Initialized by cgroup_register_subsys(); prior to this
+ it should be initialized to -1
+
+- hierarchy: an index indicating which hierarchy, if any, this
+ subsystem is currently attached to. If this is -1, then the
+ subsystem is not attached to any hierarchy, and all tasks should be
+ considered to be members of the subsystem's top_cgroup. It should
+ be initialized to -1.
+
+- name: should be initialized to a unique subsystem name prior to
+ calling cgroup_register_subsystem. Should be no longer than
+ MAX_CGROUP_TYPE_NAMELEN
+
+Each cgroup object created by the system has an array of pointers,
+indexed by subsystem id; this pointer is entirely managed by the
+subsystem; the generic cgroup code will never touch this pointer.
+
+3.2 Synchronization
+-------------------
+
+There is a global mutex, cgroup_mutex, used by the cgroup
+system. This should be taken by anything that wants to modify a
+cgroup. It may also be taken to prevent cgroups from being
+modified, but more specific locks may be more appropriate in that
+situation.
+
+See kernel/cgroup.c for more details.
+
+Subsystems can take/release the cgroup_mutex via the functions
+cgroup_lock()/cgroup_unlock(), and can
+take/release the callback_mutex via the functions
+cgroup_lock()/cgroup_unlock().
+
+Accessing a task's cgroup pointer may be done in the following ways:
+- while holding cgroup_mutex
+- while holding the task's alloc_lock (via task_lock())
+- inside an rcu_read_lock() section via rcu_dereference()
+
+3.3 Subsystem API
+--------------------------
+
+Each subsystem should:
+
+- add an entry in linux/cgroup_subsys.h
+- define a cgroup_subsys object called <name>_subsys
+
+Each subsystem may export the following methods. The only mandatory
+methods are create/destroy. Any others that are null are presumed to
+be successful no-ops.
+
+struct cgroup_subsys_state *create(struct cgroup *cont)
+LL=cgroup_mutex
+
+Called to create a subsystem state object for a cgroup. The
+subsystem should allocate its subsystem state object for the passed
+cgroup, returning a pointer to the new object on success or a
+negative error code. On success, the subsystem pointer should point to
+a structure of type cgroup_subsys_state (typically embedded in a
+larger subsystem-specific object), which will be initialized by the
+cgroup system. Note that this will be called at initialization to
+create the root subsystem state for this subsystem; this case can be
+identified by the passed cgroup object having a NULL parent (since
+it's the root of the hierarchy) and may be an appropriate place for
+initialization code.
+
+void destroy(struct cgroup *cont)
+LL=cgroup_mutex
+
+The cgroup system is about to destroy the passed cgroup; the
+subsystem should do any necessary cleanup
+
+int can_attach(struct cgroup_subsys *ss, struct cgroup *cont,
+ struct task_struct *task)
+LL=cgroup_mutex
+
+Called prior to moving a task into a cgroup; if the subsystem
+returns an error, this will abort the attach operation. If a NULL
+task is passed, then a successful result indicates that *any*
+unspecified task can be moved into the cgroup. Note that this isn't
+called on a fork. If this method returns 0 (success) then this should
+remain valid while the caller holds cgroup_mutex.
+
+void attach(struct cgroup_subsys *ss, struct cgroup *cont,
+ struct cgroup *old_cont, struct task_struct *task)
+LL=cgroup_mutex
+
+
+Called after the task has been attached to the cgroup, to allow any
+post-attachment activity that requires memory allocations or blocking.
+
+void fork(struct cgroup_subsy *ss, struct task_struct *task)
+LL=callback_mutex, maybe read_lock(tasklist_lock)
+
+Called when a task is forked into a cgroup. Also called during
+registration for all existing tasks.
+
+void exit(struct cgroup_subsys *ss, struct task_struct *task)
+LL=callback_mutex
+
+Called during task exit
+
+int populate(struct cgroup_subsys *ss, struct cgroup *cont)
+LL=none
+
+Called after creation of a cgroup to allow a subsystem to populate
+the cgroup directory with file entries. The subsystem should make
+calls to cgroup_add_file() with objects of type cftype (see
+include/linux/cgroup.h for details). Note that although this
+method can return an error code, the error code is currently not
+always handled well.
+
+void post_clone(struct cgroup_subsys *ss, struct cgroup *cont)
+
+Called at the end of cgroup_clone() to do any paramater
+initialization which might be required before a task could attach. For
+example in cpusets, no task may attach before 'cpus' and 'mems' are set
+up.
+
+void bind(struct cgroup_subsys *ss, struct cgroup *root)
+LL=callback_mutex
+
+Called when a cgroup subsystem is rebound to a different hierarchy
+and root cgroup. Currently this will only involve movement between
+the default hierarchy (which never has sub-cgroups) and a hierarchy
+that is being created/destroyed (and hence has no sub-cgroups).
+
+4. Questions
+============
+
+Q: what's up with this '/bin/echo' ?
+A: bash's builtin 'echo' command does not check calls to write() against
+ errors. If you use it in the cgroup file system, you won't be
+ able to tell whether a command succeeded or failed.
+
+Q: When I attach processes, only the first of the line gets really attached !

hooks, beyond what is already present, required to manage dynamic
job placement on large systems.
-Each task has a pointer to a cpuset. Multiple tasks may reference
-the same cpuset. Requests by a task, using the sched_setaffinity(2)
-system call to include CPUs in its CPU affinity mask, and using the
-mbind(2) and set_mempolicy(2) system calls to include Memory Nodes
-in its memory policy, are both filtered through that tasks cpuset,
-filtering out any CPUs or Memory Nodes not in that cpuset. The
-scheduler will not schedule a task on a CPU that is not allowed in
-its cpus_allowed vector, and the kernel page allocator will not
-allocate a page on a node that is not allowed in the requesting tasks
-mems_allowed vector.

-User level code may create and destroy cpusets by name in the cpuset

+
+User level code may create and destroy cpusets by name in the cgroup
virtual file system, manage the attributes and permissions of these
cpusets and which CPUs and Memory Nodes are assigned to each cpuset,
specify and query to which cpuset a task is assigned, and list the
- Cpusets are sets of allowed CPUs and Memory Nodes, known to the
kernel.
- Each task in the system is attached to a cpuset, via a pointer
- in the task structure to a reference counted cpuset structure.
+ in the task structure to a reference counted cgroup structure.
- Calls to sched_setaffinity are filtered to just those CPUs
allowed in that tasks cpuset.
- Calls to mbind and set_mempolicy are filtered to just
- in page_alloc.c, to restrict memory to allowed nodes.
- in vmscan.c, to restrict page recovery to the current cpuset.
-In addition a new file system, of type "cpuset" may be mounted,
-typically at /dev/cpuset, to enable browsing and modifying the cpusets
-presently known to the kernel. No new system calls are added for
-cpusets - all support for querying and modifying cpusets is via
-this cpuset file system.
-
-Each task under /proc has an added file named 'cpuset', displaying
-the cpuset name, as the path relative to the root of the cpuset file
-system.

In addition, the root cpuset only has the following file:
outside even a mem_exclusive cpuset.
-1.5 What does notify_on_release do ?
-------------------------------------
-
-If the notify_on_release flag is enabled (1) in a cpuset, then whenever
-the last task in the cpuset leaves (exits or attaches to some other
-cpuset) and the last child cpuset of that cpuset is removed, then
-the kernel runs the command /sbin/cpuset_release_agent, supplying the
-pathname (relative to the mount point of the cpuset file system) of the
-abandoned cpuset. This enables automatic removal of abandoned cpusets.
-The default value of notify_on_release in the root cpuset at system
-boot is disabled (0). The default value of other cpusets at creation
-is the current value of their parents notify_on_release setting.

-1.6 What is memory_pressure ?
+1.5 What is memory_pressure ?
-----------------------------
The memory_pressure of a cpuset provides a simple per-cpuset metric
of the rate that the tasks in a cpuset are attempting to free up in
times 1000.
-1.7 What is memory spread ?
+1.6 What is memory spread ?
---------------------------
There are two boolean flag files per cpuset that control where the
kernel allocates pages for the file system buffers and related in
data set, the memory allocation across the nodes in the jobs cpuset
can become very uneven.
+1.7 What is sched_load_balance ?
+--------------------------------
+
+The kernel scheduler (kernel/sched.c) automatically load balances
+tasks. If one CPU is underutilized, kernel code running on that
+CPU will look for tasks on other more overloaded CPUs and move those
+tasks to itself, within the constraints of such placement mechanisms
+as cpusets and sched_setaffinity.
+
+The algorithmic cost of load balancing and its impact on key shared
+kernel data structures such as the task list increases more than
+linearly with the number of CPUs being balanced. So the scheduler
+has support to partition the systems CPUs into a number of sched
+domains such that it only load balances within each sched domain.
+Each sched domain covers some subset of the CPUs in the system;
+no two sched domains overlap; some CPUs might not be in any sched
+domain and hence won't be load balanced.
+
+Put simply, it costs less to balance between two smaller sched domains
+than one big one, but doing so means that overloads in one of the
+two domains won't be load balanced to the other one.
+
+By default, there is one sched domain covering all CPUs, except those
+marked isolated using the kernel boot time "isolcpus=" argument.
+
+This default load balancing across all CPUs is not well suited for
+the following two situations:
+ 1) On large systems, load balancing across many CPUs is expensive.
+ If the system is managed using cpusets to place independent jobs
+ on separate sets of CPUs, full load balancing is unnecessary.
+ 2) Systems supporting realtime on some CPUs need to minimize
+ system overhead on those CPUs, including avoiding task load
+ balancing if that is not needed.
+
+When the per-cpuset flag "sched_load_balance" is enabled (the default
+setting), it requests that all the CPUs in that cpusets allowed 'cpus'
+be contained in a single sched domain, ensuring that load balancing
+can move a task (not otherwised pinned, as by sched_setaffinity)
+from any CPU in that cpuset to any other.
+
+When the per-cpuset flag "sched_load_balance" is disabled, then the
+scheduler will avoid load balancing across the CPUs in that cpuset,
+--except-- in so far as is necessary because some overlapping cpuset
+has "sched_load_balance" enabled.
+
+So, for example, if the top cpuset has the flag "sched_load_balance"
+enabled, then the scheduler will have one sched domain covering all
+CPUs, and the setting of the "sched_load_balance" flag in any other
+cpusets won't matter, as we're already fully load balancing.
+
+Therefore in the above two situations, the top cpuset flag
+"sched_load_balance" should be disabled, and only some of the smaller,
+child cpusets have this flag enabled.
+
+When doing this, you don't usually want to leave any unpinned tasks in
+the top cpuset that might use non-trivial amounts of CPU, as such tasks
+may be artificially constrained to some subset of CPUs, depending on
+the particulars of this flag setting in descendent cpusets. Even if
+such a task could use spare CPU cycles in some other CPUs, the kernel
+scheduler might not consider the possibility of load balancing that
+task to that underused CPU.
+
+Of course, tasks pinned to a particular CPU can be left in a cpuset
+that disables "sched_load_balance" as those tasks aren't going anywhere
+else anyway.
+
+There is an impedance mismatch here, between cpusets and sched domains.
+Cpusets are hierarchical and nest. Sched domains are flat; they don't
+overlap and each CPU is in at most one sched domain.
+
+It is necessary for sched domains to be flat because load balancing
+across partially overlapping sets of CPUs would risk unstable dynamics
+that would be beyond our understanding. So if each of two partially
+overlapping cpusets enables the flag 'sched_load_balance', then we
+form a single sched domain that is a superset of both. We won't move
+a task to a CPU outside it cpuset, but the scheduler load balancing
+code might waste some compute cycles considering that possibility.
+
+This mismatch is why there is not a simple one-to-one relation
+between which cpusets have the flag "sched_load_balance" enabled,
+and the sched domain configuration. If a cpuset enables the flag, it
+will get balancing across all its CPUs, but if it disables the flag,
+it will only be assured of no load balancing if no other overlapping
+cpuset enables the flag.
+
+If two cpusets have partially overlapping 'cpus' allowed, and only
+one of them has this flag enabled, then the other may find its
+tasks only partially load balanced, just on the overlapping CPUs.
+This is just the general case of the top_cpuset example given a few
+paragraphs above. In the general case, as in the top cpuset case,
+don't leave tasks that might use non-trivial amounts of CPU in
+such partially load balanced cpusets, as they may be artificially
+constrained to some subset of the CPUs allowed to them, for lack of
+load balancing to the other CPUs.
+
+1.7.1 sched_load_balance implementation details.
+------------------------------------------------
+
+The per-cpuset flag 'sched_load_balance' defaults to enabled (contrary
+to most cpuset flags.) When enabled for a cpuset, the kernel will
+ensure that it can load balance across all the CPUs in that cpuset
+(makes sure that all the CPUs in the cpus_allowed of that cpuset are
+in the same sched domain.)
+
+If two overlapping cpusets both have 'sched_load_balance' enabled,
+then they will be (must be) both in the same sched domain.
+
+If, as is the default, the top cpuset has 'sched_load_balance' enabled,
+then by the above that means there is a single sched domain covering
+the whole system, regardless of any other cpuset settings.
+
+The kernel commits to user space that it will avoid load balancing
+where it can. It will pick as fine a granularity partition of sched
+domains as it can while still providing load balancing for any set
+of CPUs allowed to a cpuset having 'sched_load_balance' enabled.
+
+The internal kernel cpuset to scheduler interface passes from the
+cpuset code to the scheduler code a partition of the load balanced
+CPUs in the system. This partition is a set of subsets (represented
+as an array of cpumask_t) of CPUs, pairwise disjoint, that cover all
+the CPUs that must be load balanced.
+
+Whenever the 'sched_load_balance' flag changes, or CPUs come or go
+from a cpuset with this flag enabled, or a cpuset with this flag
+enabled is removed, the cpuset code builds a new such partition and
+passes it to the scheduler sched domain setup code, to have the sched
+domains rebuilt as necessary.
+
+This partition exactly defines what sched domains the scheduler should
+setup - one sched domain for each element (cpumask_t) in the partition.
+
+The scheduler remembers the currently active sched domain partitions.
+When the scheduler routine partition_sched_domains() is invoked from
+the cpuset code to update these sched domains, it compares the new
+partition requested with the current, and updates its sched domains,
+removing the old and adding the new, for each change.
1.8 How do I use cpusets ?
--------------------------
To start a new job that is to be contained within a cpuset, the steps are:
1) mkdir /dev/cpuset
- 2) mount -t cpuset none /dev/cpuset
+ 2) mount -t cgroup -ocpuset cpuset /dev/cpuset
3) Create the new cpuset by doing mkdir's and write's (or echo's) in
the /dev/cpuset virtual file system.
4) Start a task that will be the "founding father" of the new job.
named "Charlie", containing just CPUs 2 and 3, and Memory Node 1,
and then start a subshell 'sh' in that cpuset:
- mount -t cpuset none /dev/cpuset
+ mount -t cgroup -ocpuset cpuset /dev/cpuset
cd /dev/cpuset
mkdir Charlie
cd Charlie
virtual filesystem.
To mount it, type:
-# mount -t cpuset none /dev/cpuset
+# mount -t cgroup -o cpuset cpuset /dev/cpuset
Then under /dev/cpuset you can find a tree that corresponds to the
tree of the cpusets in the system. For instance, /dev/cpuset
This will fail if the cpuset is in use (has cpusets inside, or has
processes attached).
+Note that for legacy reasons, the "cpuset" filesystem exists as a
+wrapper around the cgroup filesystem.
+
+The command
+
+mount -t cpuset X /dev/cpuset
+
+is equivalent to
+
+mount -t cgroup -ocpuset X /dev/cpuset
+echo "/sbin/cpuset_release_agent" > /dev/cpuset/release_agent
+

+What: sys_sysctl
+When: September 2010
+Option: CONFIG_SYSCTL_SYSCALL
+Why: The same information is available in a more convenient from
+ /proc/sys, and none of the sysctl variables appear to be
+ important performance wise.
+
+ Binary sysctls are a long standing source of subtle kernel
+ bugs and security issues.
+
+ When I looked several months ago all I could find after
+ searching several distributions were 5 user space programs and
+ glibc (which falls back to /proc/sys) using this syscall.
+
+ The man page for sysctl(2) documents it as unusable for user
+ space programs.
+
+ sysctl(2) is not generally ABI compatible to a 32bit user
+ space application on a 64bit and a 32bit kernel.
+
+ For the last several months the policy has been no new binary
+ sysctls and no one has put forward an argument to use them.
+
+ Binary sysctls issues seem to keep happening appearing so
+ properly deprecating them (with a warning to user space) and a
+ 2 year grace warning period will mean eventually we can kill
+ them and end the pain.
+
+ In the mean time individual binary sysctls can be dealt with
+ in a piecewise fashion.

+Extended crashkernel syntax
+===========================
+
+While the "crashkernel=size[@offset]" syntax is sufficient for most
+configurations, sometimes it's handy to have the reserved memory dependent
+on the value of System RAM -- that's mostly for distributors that pre-setup
+the kernel command line to avoid a unbootable system after some memory has
+been removed from the machine.
+
+The syntax is:
+
+ crashkernel=<range1>:<size1>[,<range2>:<size2>,...][@offset]
+ range=start-[end]
+
+For example:
+
+ crashkernel=512M-2G:64M,2G-:128M
+
+This would mean:
+
+ 1) if the RAM is smaller than 512M, then don't reserve anything
+ (this is the "rescue" case)
+ 2) if the RAM size is between 512M and 2G, then reserve 64M
+ 3) if the RAM size is larger than 2G, then reserve 128M

+ Using the Linux Kernel Markers
+
+ Mathieu Desnoyers
+
+
+This document introduces Linux Kernel Markers and their use. It provides
+examples of how to insert markers in the kernel and connect probe functions to
+them and provides some examples of probe functions.
+
+
+* Purpose of markers
+
+A marker placed in code provides a hook to call a function (probe) that you can
+provide at runtime. A marker can be "on" (a probe is connected to it) or "off"
+(no probe is attached). When a marker is "off" it has no effect, except for
+adding a tiny time penalty (checking a condition for a branch) and space
+penalty (adding a few bytes for the function call at the end of the
+instrumented function and adds a data structure in a separate section). When a
+marker is "on", the function you provide is called each time the marker is
+executed, in the execution context of the caller. When the function provided
+ends its execution, it returns to the caller (continuing from the marker site).
+
+You can put markers at important locations in the code. Markers are
+lightweight hooks that can pass an arbitrary number of parameters,
+described in a printk-like format string, to the attached probe function.
+
+They can be used for tracing and performance accounting.
+
+
+* Usage
+
+In order to use the macro trace_mark, you should include linux/marker.h.
+
+#include <linux/marker.h>
+
+And,
+
+trace_mark(subsystem_event, "%d %s", someint, somestring);
+Where :
+- subsystem_event is an identifier unique to your event
+ - subsystem is the name of your subsystem.
+ - event is the name of the event to mark.
+- "%d %s" is the formatted string for the serializer.
+- someint is an integer.
+- somestring is a char pointer.
+
+Connecting a function (probe) to a marker is done by providing a probe (function
+to call) for the specific marker through marker_probe_register() and can be
+activated by calling marker_arm(). Marker deactivation can be done by calling
+marker_disarm() as many times as marker_arm() has been called. Removing a probe
+is done through marker_probe_unregister(); it will disarm the probe and make
+sure there is no caller left using the probe when it returns. Probe removal is
+preempt-safe because preemption is disabled around the probe call. See the
+"Probe example" section below for a sample probe module.
+
+The marker mechanism supports inserting multiple instances of the same marker.
+Markers can be put in inline functions, inlined static functions, and
+unrolled loops as well as regular functions.
+
+The naming scheme "subsystem_event" is suggested here as a convention intended
+to limit collisions. Marker names are global to the kernel: they are considered
+as being the same whether they are in the core kernel image or in modules.
+Conflicting format strings for markers with the same name will cause the markers
+to be detected to have a different format string not to be armed and will output
+a printk warning which identifies the inconsistency:
+
+"Format mismatch for probe probe_name (format), marker (format)"
+
+
+* Probe / marker example
+
+See the example provided in samples/markers/src
+
+Compile them with your kernel.
+
+Run, as root :
+modprobe marker-example (insmod order is not important)
+modprobe probe-example
+cat /proc/marker-example (returns an expected error)
+rmmod marker-example probe-example
+dmesg
Any atomic operation that modifies some state in memory and returns information
about the state (old or new) implies an SMP-conditional general memory barrier
-(smp_mb()) on each side of the actual operation. These include:
+(smp_mb()) on each side of the actual operation (with the exception of
+explicit lock operations, described later). These include:
xchg();
cmpxchg();
do need memory barriers as a lock primitive generally has to do things in a
specific order.
-
Basically, each usage case has to be carefully considered as to whether memory
barriers are needed or not.
+The following operations are special locking primitives:
+
+ test_and_set_bit_lock();
+ clear_bit_unlock();
+ __clear_bit_unlock();
+
+These implement LOCK-class and UNLOCK-class operations. These should be used in
+preference to other operations when implementing locking primitives, because
+their implementations can be optimised on many architectures.
+
[!] Note that special memory barrier primitives are available for these
situations because on some CPUs the atomic instructions used imply full memory
barriers, and so barrier instructions are superfluous in conjunction with them,

-ABOUT
------
-This file describes the new arch/mips/kernel/time.c, related files and the
-services they provide.
-
-If you are short in patience and just want to know how to use time.c for a
-new board or convert an existing board, go to the last section.
-
-
-FILES, COMPATABILITY AND CONFIGS
----------------------------------
-
-The old arch/mips/kernel/time.c is renamed to old-time.c.
-
-A new time.c is put there, together with include/asm-mips/time.h.
-
-Two configs variables are introduced, CONFIG_OLD_TIME_C and CONFIG_NEW_TIME_C.
-So we allow boards using
-
- 1) old time.c (CONFIG_OLD_TIME_C)
- 2) new time.c (CONFIG_NEW_TIME_C)
- 3) neither (their own private time.c)
-
-However, it is expected every board will move to the new time.c in the near
-future.
-
-
-WHAT THE NEW CODE PROVIDES?
----------------------------
-
-The new time code provide the following services:
-
- a) Implements functions required by Linux common code:
- time_init
-
- b) provides an abstraction of RTC and null RTC implementation as default.
- extern unsigned long (*rtc_get_time)(void);
- extern int (*rtc_set_time)(unsigned long);
-
- c) high-level and low-level timer interrupt routines where the timer
- interrupt source may or may not be the CPU timer. The high-level
- routine is dispatched through do_IRQ() while the low-level is
- dispatched in assemably code (usually int-handler.S)
-
-
-WHAT THE NEW CODE REQUIRES?
----------------------------
-
-For the new code to work properly, each board implementation needs to supply
-the following functions or values:
-
- a) board_time_init - a function pointer. Invoked at the beginnig of
- time_init(). It is optional.
- 1. (optional) set up RTC routines
- 2. (optional) calibrate and set the mips_hpt_frequency
-
- b) plat_timer_setup - a function pointer. Invoked at the end of time_init()
- 1. (optional) over-ride any decisions made in time_init()
- 2. set up the irqaction for timer interrupt.
- 3. enable the timer interrupt
-
- c) (optional) board-specific RTC routines.
-
- d) (optional) mips_hpt_frequency - It must be definied if the board
- is using CPU counter for timer interrupt.
-
-
-PORTING GUIDE
--------------
-
-Step 1: decide how you like to implement the time services.
-
- a) does this board have a RTC? If yes, implement the two RTC funcs.
-
- b) does the CPU have counter/compare registers?
-
- If the answer is no, you need a timer to provide the timer interrupt
- at 100 HZ speed.
-
- c) The following sub steps assume your CPU has counter register.
- Do you plan to use the CPU counter register as the timer interrupt
- or use an exnternal timer?
-
- In order to use CPU counter register as the timer interrupt source, you
- must know the counter speed (mips_hpt_frequency). It is usually the
- same as the CPU speed or an integral divisor of it.
-
- d) decide on whether you want to use high-level or low-level timer
- interrupt routines. The low-level one is presumably faster, but should
- not make too mcuh difference.
-
-
-Step 2: the machine setup() function
-
- If you supply board_time_init(), set the function poointer.
-
-
-Step 3: implement rtc routines, board_time_init() and plat_timer_setup()
- if needed.
-
- board_time_init() -
- a) (optional) set up RTC routines,
- b) (optional) calibrate and set the mips_hpt_frequency
- (only needed if you intended to use cpu counter as timer interrupt
- source)
-
- plat_timer_setup() -
- a) (optional) over-write any choices made above by time_init().
- b) machine specific code should setup the timer irqaction.
- c) enable the timer interrupt
-
-
- If the RTC chip is a common chip, I suggest the routines are put under
- arch/mips/libs. For example, for DS1386 chip, one would create
- rtc-ds1386.c under arch/mips/lib directory. Add the following line to
- the arch/mips/lib/Makefile:
-
- obj-$(CONFIG_DDB5476) += rtc-ds1386.o
-
-Step 4: if you are using low-level timer interrupt, change your interrupt
- dispathcing code to check for timer interrupt and jump to
- ll_timer_interrupt() directly if one is detected.
-
-Step 5: Modify arch/mips/config.in and add CONFIG_NEW_TIME_C to your machine.
- Modify the appropriate defconfig if applicable.
-
-Final notes:
-
-For some tricky cases, you may need to add your own wrapper functions
-for some of the functions in time.c.
-
-For example, you may define your own timer interrupt routine, which does
-some of its own processing and then calls timer_interrupt().
-
-You can also over-ride any of the built-in functions (RTC routines
-and/or timer interrupt routine).
-
-
-PORTING NOTES FOR SMP
-----------------------
-
-If you have a SMP box, things are slightly more complicated.
-
-The time service running every jiffy is logically divided into two parts:
-
- 1) the one for the whole system (defined in timer_interrupt())
- 2) the one that should run for each CPU (defined in local_timer_interrupt())
-
-You need to decide on your timer interrupt sources.
-
- case 1) - whole system has only one timer interrupt delivered to one CPU
-
- In this case, you set up timer interrupt as in UP systems. In addtion,
- you need to set emulate_local_timer_interrupt to 1 so that other
- CPUs get to call local_timer_interrupt().
-
- THIS IS CURRENTLY NOT IMPLEMNETED. However, it is rather easy to write
- one should such a need arise. You simply make a IPI call.
-
- case 2) - each CPU has a separate timer interrupt
-
- In this case, you need to set up IRQ such that each of them will
- call local_timer_interrupt(). In addition, you need to arrange
- one and only one of them to call timer_interrupt().
-
- You can also do the low-level version of those interrupt routines,
- following similar dispatching routes described above.

In case the STD does not work on your system even in the minimal configuration
and compiling more drivers as modules is not practical or some modules cannot
be unloaded, you can use one of the more advanced debugging techniques to find
-the problem. First, if there is a serial port in your box, you can set the
-CONFIG_DISABLE_CONSOLE_SUSPEND kernel configuration option and try to log kernel
+the problem. First, if there is a serial port in your box, you can boot the
+kernel with the 'no_console_suspend' parameter and try to log kernel
messages using the serial console. This may provide you with some information
about the reasons of the suspend (resume) failure. Alternatively, it may be
possible to use a FireWire port for debugging with firescope
Namely, as the first step of the hibernation procedure the function
freeze_processes() (defined in kernel/power/process.c) is called. It executes
try_to_freeze_tasks() that sets TIF_FREEZE for all of the freezable tasks and
-sends a fake signal to each of them. A task that receives such a signal and has
-TIF_FREEZE set, should react to it by calling the refrigerator() function
-(defined in kernel/power/process.c), which sets the task's PF_FROZEN flag,
-changes its state to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is
-cleared for it. Then, we say that the task is 'frozen' and therefore the set of
-functions handling this mechanism is called 'the freezer' (these functions are
+either wakes them up, if they are kernel threads, or sends fake signals to them,
+if they are user space processes. A task that has TIF_FREEZE set, should react
+to it by calling the function called refrigerator() (defined in
+kernel/power/process.c), which sets the task's PF_FROZEN flag, changes its state
+to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is cleared for it.
+Then, we say that the task is 'frozen' and therefore the set of functions
+handling this mechanism is referred to as 'the freezer' (these functions are
defined in kernel/power/process.c and include/linux/freezer.h). User space
processes are generally frozen before kernel threads.
For user space processes try_to_freeze() is called automatically from the
signal-handling code, but the freezable kernel threads need to call it
-explicitly in suitable places. The code to do this may look like the following:
+explicitly in suitable places or use the wait_event_freezable() or
+wait_event_freezable_timeout() macros (defined in include/linux/freezer.h)
+that combine interruptible sleep with checking if TIF_FREEZE is set and calling
+try_to_freeze(). The main loop of a freezable kernel thread may look like the
+following one:
+ set_freezable();
do {
hub_events();
- wait_event_interruptible(khubd_wait,
- !list_empty(&hub_event_list));
- try_to_freeze();
- } while (!signal_pending(current));
+ wait_event_freezable(khubd_wait,
+ !list_empty(&hub_event_list) ||
+ kthread_should_stop());
+ } while (!kthread_should_stop() || !list_empty(&hub_event_list));
(from drivers/usb/core/hub.c::hub_thread()).
If a freezable kernel thread fails to call try_to_freeze() after the freezer has
set TIF_FREEZE for it, the freezing of tasks will fail and the entire
hibernation operation will be cancelled. For this reason, freezable kernel
-threads must call try_to_freeze() somewhere.
+threads must call try_to_freeze() somewhere or use one of the
+wait_event_freezable() and wait_event_freezable_timeout() macros.
After the system memory state has been restored from a hibernation image and
devices have been reinitialized, the function thaw_processes() is called in
The majority of these are user space processes, but if any of the kernel threads
may cause something like this to happen, they have to be freezable.
-2. The second reason is to prevent user space processes and some kernel threads
+2. Next, to create the hibernation image we need to free a sufficient amount of
+memory (approximately 50% of available RAM) and we need to do that before
+devices are deactivated, because we generally need them for swapping out. Then,
+after the memory for the image has been freed, we don't want tasks to allocate
+additional memory and we prevent them from doing that by freezing them earlier.
+[Of course, this also means that device drivers should not allocate substantial
+amounts of memory from their .suspend() callbacks before hibernation, but this
+is e separate issue.]
+
+3. The third reason is to prevent user space processes and some kernel threads
from interfering with the suspending and resuming of devices. A user space
process running on a second CPU while we are suspending devices may, for
example, be troublesome and without the freezing of tasks we would need some
thawed after the driver's .resume() callback has run, so it won't be accessing
the device while it's suspended.
-3. Another reason for freezing tasks is to prevent user space processes from
+4. Another reason for freezing tasks is to prevent user space processes from
realizing that hibernation (or suspend) operation takes place. Ideally, user
space processes should not notice that such a system-wide operation has occurred
and should continue running without any problems after the restore (or resume
/sys/power/disk controls the operating mode of the suspend-to-disk
mechanism. Suspend-to-disk can be handled in several ways. We have a
few options for putting the system to sleep - using the platform driver
-(e.g. ACPI or other pm_ops), powering off the system or rebooting the
+(e.g. ACPI or other suspend_ops), powering off the system or rebooting the

Additionally, /sys/power/disk can be used to turn on one of the two testing

-/proc/sound, /dev/sndstat
--------------------------
-
-/proc/sound and /dev/sndstat is not supported by the
-driver. To find out whether the driver succeeded loading,
-check the kernel log (dmesg).
-
-
-ALaw/uLaw sample formats
-------------------------
-
-This driver does not support the ALaw/uLaw sample formats.
-ALaw is the default mode when opening a sound device
-using OSS/Free. The reason for the lack of support is
-that the hardware does not support these formats, and adding
-conversion routines to the kernel would lead to very ugly
-code in the presence of the mmap interface to the driver.
-And since xquake uses mmap, mmap is considered important :-)
-and no sane application uses ALaw/uLaw these days anyway.
-In short, playing a Sun .au file as follows:
-
-cat my_file.au > /dev/dsp
-
-does not work. Instead, you may use the play script from
-Chris Bagwell's sox-12.14 package (available from the URL
-below) to play many different audio file formats.
-The script automatically determines the audio format
-and does do audio conversions if necessary.
-http://home.sprynet.com/sprynet/cbagwell/projects.html
-
-
-Blocking vs. nonblocking IO
----------------------------
-
-Unlike OSS/Free this driver honours the O_NONBLOCK file flag
-not only during open, but also during read and write.
-This is an effort to make the sound driver interface more
-regular. Timidity has problems with this; a patch
-is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html.
-(Timidity patched will also run on OSS/Free).
-
-
-MIDI UART
----------
-
-The driver supports a simple MIDI UART interface, with
-no ioctl's supported.
-
-
-MIDI synthesizer
-----------------
-
-This soundcard does not have any hardware MIDI synthesizer;
-MIDI synthesis has to be done in software. To allow this
-the driver/soundcard supports two PCM (/dev/dsp) interfaces.
-
-There is a freely available software package that allows
-MIDI file playback on this soundcard called Timidity.
-See http://www.cgs.fi/~tt/timidity/.

- Kprobes allows you to trap at almost any kernel address and
- execute a callback function. register_kprobe() establishes
- a probepoint and specifies the callback. Kprobes is useful
- for kernel debugging, non-intrusive instrumentation and testing.
- If in doubt, say "N".

- bool "Watchdog Timer Support"
- ---help---
- If you say Y here (and to one of the following options) and create a
- character special file /dev/watchdog with major number 10 and minor
- number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
- subsequently opening the file and then failing to write to it for
- longer than 1 minute will result in rebooting the machine. This
- could be useful for a networked machine that needs to come back
- on-line as fast as possible after a lock-up. There's both a watchdog
- implementation entirely in software (which can sometimes fail to
- reboot the machine) and a driver for hardware watchdog boards, which
- are more robust and can also keep track of the temperature inside
- your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
- in the kernel source.
-
- The watchdog is usually used together with the watchdog daemon
- which is available from
- <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
- also monitor NFS connections and can reboot the machine when the process
- table is full.
-
- If unsure, say N.

- your system or have any real effect. The only way to be sure
- that this driver does what you want is to make sure you
- are running it on an EPX-C3 from Winsystems with the watchdog
- timer at IO address 0x1ee and 0x1ef. It will write to both those
- IO ports. Basically, the assumption is made that if you compile
- this driver into your kernel and/or load it as a module, that you
- know what you are doing and that you are in fact running on an
- EPX-C3 board!

- To compile this driver as a module, choose M here: the

-/*
- * Theory of Operation:
- * The Watch-Dog Timer is provided to ensure that standalone
- * Systems can always recover from catastrophic conditions that
- * caused the CPU to crash. This condition may have occured by
- * external EMI or a software bug. When the CPU stops working
- * correctly, hardware on the board will either perform a hardware
- * reset (cold boot) or a non-maskable interrupt (NMI) to bring the
- * system back to a known state.
- *
- * The Watch-Dog Timer is controlled by two I/O Ports.
- * 443 hex - Read - Enable or refresh the Watch-Dog Timer
- * 043 hex - Read - Disable the Watch-Dog Timer
- *
- * To enable the Watch-Dog Timer, a read from I/O port 443h must
- * be performed. This will enable and activate the countdown timer
- * which will eventually time out and either reset the CPU or cause
- * an NMI depending on the setting of a jumper. To ensure that this
- * reset condition does not occur, the Watch-Dog Timer must be
- * periodically refreshed by reading the same I/O port 443h.
- * The Watch-Dog Timer is disabled by reading I/O port 043h.
- *
- * The Watch-Dog Timer Time-Out Period is set via jumpers.
- * It can be 1, 2, 10, 20, 110 or 220 seconds.

-/*
- * ALi M7101 PMU Computer Watchdog Timer driver
- *
- * Based on w83877f_wdt.c by Scott Jennings <linuxdrivers@oro.net>
- * and the Cobalt kernel WDT timer driver by Tim Hockin
- * <thockin@cobaltnet.com>
- *
- * (c)2002 Steve Hill <steve@navaho.co.uk>
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.
- *
- * Additions:
- * Aug 23, 2004 - Added use_gpio module parameter for use on revision a1d PMUs
- * found on very old cobalt hardware.
- * -- Mike Waychison <michael.waychison@sun.com>

- * 1. BIOS
- * For P4SBx:
- * BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
- * For P4DPx:
- * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
- * This setting enables or disables Watchdog function. When enabled, the
- * default watchdog timer is set to be 5 minutes (about 4’35”). It is
- * enough to load and run the OS. The application (service or driver) has
- * to take over the control once OS is running up and before watchdog
- * expires.
- *
- * 2. JUMPER
- * For P4SBx: JP39
- * For P4DPx: JP37
- * This jumper is used for safety. Closed is enabled. This jumper
- * prevents user enables watchdog in BIOS by accident.
- *
- * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
- *
- * The documentation lists motherboards P4SBx and P4DPx series as of
- * 20-March-2002. However, this code works flawlessly with much newer
- * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
- *
- * The original iTCO driver as written does not actually reset the
- * watchdog timer on these machines, as a result they reboot after five
- * minutes.
- *
- * NOTE: You may leave the Watchdog function disabled in the SuperMicro
- * BIOS to avoid a "boot-race"... This driver will enable watchdog
- * functionality even if it's disabled in the BIOS once the /dev/watchdog
- * file is opened.

- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system
- * automatically and is defined at I/O port 0443H. To enable the
- * watchdog timer and allow the system to reset, write I/O port 0443H.
- * To disable the timer, write I/O port 0441H for the system to stop the
- * watchdog function. The timer has a tolerance of 20% for its
- * intervals.
- *
- * The following describes how the timer should be programmed.
- *
- * Enabling Watchdog:
- * MOV AX,000FH (Choose the values from 0 to F)
- * MOV DX,0443H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,000FH (Any value is fine.)
- * MOV DX,0441H
- * OUT DX,AX
- *
- * Watchdog timer control table:
- * Level Value Time/sec | Level Value Time/sec
- * 1 F 0 | 9 7 16
- * 2 E 2 | 10 6 18
- * 3 D 4 | 11 5 20
- * 4 C 6 | 12 4 22
- * 5 B 8 | 13 3 24

- * PC Watchdog Driver
- * by Ken Hollis (khollis@bitgate.com)
- *
- * Permission granted from Simon Machell (smachell@berkprod.com)
- * Written for the Linux Kernel, and GPLed by Ken Hollis
- *
- * 960107 Added request_region routines, modulized the whole thing.
- * 960108 Fixed end-of-file pointer (Thanks to Dan Hollis), added
- * WD_TIMEOUT define.
- * 960216 Added eof marker on the file, and changed verbose messages.
- * 960716 Made functional and cosmetic changes to the source for
- * inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
- * 960717 Removed read/seek routines, replaced with ioctl. Also, added
- * check_region command due to Alan's suggestion.
- * 960821 Made changes to compile in newer 2.0.x kernels. Added
- * "cold reboot sense" entry.
- * 960825 Made a few changes to code, deleted some defines and made
- * typedefs to replace them. Made heartbeat reset only available
- * via ioctl, and removed the write routine.
- * 960828 Added new items for PC Watchdog Rev.C card.
- * 960829 Changed around all of the IOCTLs, added new features,
- * added watchdog disable/re-enable routines. Added firmware
- * version reporting. Added read routine for temperature.
- * Removed some extra defines, added an autodetect Revision
- * routine.
- * 961006 Revised some documentation, fixed some cosmetic bugs. Made
- * drivers to panic the system if it's overheating at bootup.
- * 961118 Changed some verbiage on some of the output, tidied up
- * code bits, and added compatibility to 2.1.x.
- * 970912 Enabled board on open and disable on close.
- * 971107 Took account of recent VFS changes (broke read).
- * 971210 Disable board on initialisation in case board already ticking.
- * 971222 Changed open/close for temperature handling
- * Michael Meskes <meskes@debian.org>.
- * 980112 Used minor numbers from include/linux/miscdevice.h
- * 990403 Clear reset status after reading control status register in
- * pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
- * 990605 Made changes to code to support Firmware 1.22a, added
- * fairly useless proc entry.
- * 990610 removed said useless proc code for the merge <alan>
- * 000403 Removed last traces of proc code. <davej>
- * 011214 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>
- * Added timeout module option to override default

- * made the keepalive ping an internal subroutine
- * made wdt_stop and wdt_start module params
- * added extra printk's for startup problems
- * added MODULE_AUTHOR and MODULE_DESCRIPTION info
- *
- *
- * This WDT driver is different from the other Linux WDT
- * drivers in the following ways:
- * *) The driver will ping the watchdog by itself, because this
- * particular WDT has a very short timeout (one second) and it
- * would be insane to count on any userspace daemon always
- * getting scheduled within that time frame.

- *
- * Watchdog Timer Configuration
- *
- * The function of the watchdog timer is to reset the system automatically
- * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
- * and allow the system to reset, write appropriate values from the table
- * below to I/O port 0120H and 0121H. To disable the timer, write a zero
- * value to I/O port 0121H for the system to stop the watchdog function.
- *
- * The following describes how the timer should be programmed (according to
- * the vendor documentation)
- *
- * Enabling Watchdog:
- * MOV AX,000AH (enable, phase I)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000BH (enable, phase II)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000nH (set multiplier n, from 1-4)
- * MOV DX,0120H
- * OUT DX,AX
- * MOV AX,000mH (set base timer m, from 0-F)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Reset timer:
- * MOV AX,000mH (same as set base timer, above)
- * MOV DX,0121H
- * OUT DX,AX
- *
- * Disabling Watchdog:
- * MOV AX,0000H (a zero value)
- * MOV DX,0120H
- * OUT DX,AX
- *
- * Watchdog timeout configuration values:
- * N
- * M | 1 2 3 4
- * --|----------------------------------
- * 0 | 0.5s 5s 50s 100s
- * 1 | 1s 10s 100s 200s
- * 2 | 1.5s 15s 150s 300s
- * 3 | 2s 20s 200s 400s
- * 4 | 2.5s 25s 250s 500s
- * 5 | 3s 30s 300s 600s
- * 6 | 3.5s 35s 350s 700s
- * 7 | 4s 40s 400s 800s
- * 8 | 4.5s 45s 450s 900s
- * 9 | 5s 50s 500s 1000s
- * A | 5.5s 55s 550s 1100s
- * B | 6s 60s 600s 1200s
- * C | 6.5s 65s 650s 1300s
- * D | 7s 70s 700s 1400s
- * E | 7.5s 75s 750s 1500s
- * F | 8s 80s 800s 1600s
- *
- * Another way to say the same things is:
- * For N=1, Timeout = (M+1) * 0.5s
- * For N=2, Timeout = (M+1) * 5s
- * For N=3, Timeout = (M+1) * 50s
- * For N=4, Timeout = (M+1) * 100s

- *
- * (c) Copyright 2001 Scott Jennings <linuxdrivers@oro.net>
- * 9/27 - 2001 [Initial release]
- *
- * Additional fixes Alan Cox
- * - Fixed formatting
- * - Removed debug printks
- * - Fixed SMP built kernel deadlock
- * - Switched to private locks not lock_kernel
- * - Used ioremap/writew/readw
- * - Added NOWAYOUT support
- * 4/12 - 2002 Changes by Rob Radez <rob@osinvestor.com>
- * - Change comments
- * - Eliminate fop_llseek
- * - Change CONFIG_WATCHDOG_NOWAYOUT semantics
- * - Add KERN_* tags to printks
- * - fix possible wdt_is_open race
- * - Report proper capabilities in watchdog_info
- * - Add WDIOC_{GETSTATUS, GETBOOTSTATUS, SETTIMEOUT,
- * GETTIMEOUT, SETOPTIONS} ioctls
- * 09/8 - 2003 Changes by Wim Van Sebroeck <wim@iguana.be>
- * - cleanup of trailing spaces
- * - added extra printk's for startup problems
- * - use module_param
- * - made timeout (the emulated heartbeat) a module_param
- * - made the keepalive ping an internal subroutine
- * 3/27 - 2004 Changes by Sean Young <sean@mess.org>
- * - set MMCR_BASE to 0xfffef000
- * - CBAR does not need to be read
- * - removed debugging printks
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.
- *
- * This driver uses memory mapped IO, and spinlock.

- * Default clock division ratio is 5.25 msecs. For an additional table of
- * values, consult the asm-sh/watchdog.h. Overload this at module load
- * time.
- *
- * In order for this to work reliably we need to have HZ set to 1000 or
- * something quite higher than 100 (or we need a proper high-res timer
- * implementation that will deal with this properly), otherwise the 10ms
- * resolution of a jiffy is enough to trigger the overflow. For things like
- * the SH-4 and SH-5, this isn't necessarily that big of a problem, though
- * for the SH-2 and SH-3, this isn't recommended unless the WDT is absolutely
- * necssary.
- *
- * As a result of this timing problem, the only modes that are particularly
- * feasible are the 4096 and the 2048 divisors, which yeild 5.25 and 2.62ms
- * overflow periods respectively.
- *
- * Also, since we can't really expect userspace to be responsive enough
- * before the overflow happens, we maintain two seperate timers .. One in
- * the kernel for clearing out WOVF every 2ms or so (again, this depends on
- * HZ == 1000), and another for monitoring userspace writes to the WDT device.
- *
- * As such, we currently use a configurable heartbeat interval which defaults
- * to 30s. In this case, the userspace daemon is only responsible for periodic
- * writes to the device before the next heartbeat is scheduled. If the daemon
- * misses its deadline, the kernel timer will allow the WDT to overflow.

- *
- * History:
- * 2003 - Created version 1.0 for Linux 2.4.x.
- * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
- * features. Released version 1.1
- *
- * Theory of operation:
- *
- * A Watchdog Timer (WDT) is a hardware circuit that can
- * reset the computer system in case of a software fault.
- * You probably knew that already.
- *
- * Usually a userspace daemon will notify the kernel WDT driver
- * via the /dev/watchdog special device file that userspace is
- * still alive, at regular intervals. When such a notification
- * occurs, the driver will usually tell the hardware watchdog
- * that everything is in order, and that the watchdog should wait
- * for yet another little while to reset the system.
- * If userspace fails (RAM error, kernel bug, whatever), the
- * notifications cease to occur, and the hardware watchdog will
- * reset the system (causing a reboot) after the timeout occurs.
- *
- * Create device with:
- * mknod /dev/watchdog c 10 130
- *
- * For an example userspace keep-alive daemon, see:
- * Documentation/watchdog/watchdog.txt

- *
- * 03/96: Angelo Haritsis <ah@doc.ic.ac.uk> :

- *
- * 20011127 Joel Becker (jlbec@evilplan.org>
- * Added soft_noboot; Allows testing the softdog trigger without

- * Added WDIOC_GETTIMEOUT and WDIOC_SETTIMOUT.
- *
- * 20020530 Joel Becker <joel.becker@oracle.com>
- * Added Matt Domsch's nowayout module option.

- * fix possible wdt_is_open race
- * changed watchdog_info to correctly reflect what the driver offers
- * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
- * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
- * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
- * added extra printk's for startup problems
- * use module_param
- * made timeout (the emulated heartbeat) a module_param
- * made the keepalive ping an internal subroutine
- *
- * This WDT driver is different from most other Linux WDT
- * drivers in that the driver will ping the watchdog by itself,
- * because this particular WDT has a very short timeout (1.6
- * seconds) and it would be insane to count on any userspace
- * daemon always getting scheduled within that time frame.

+ ---help---
+ If you say Y here (and to one of the following options) and create a
+ character special file /dev/watchdog with major number 10 and minor
+ number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
+ subsequently opening the file and then failing to write to it for
+ longer than 1 minute will result in rebooting the machine. This
+ could be useful for a networked machine that needs to come back
+ on-line as fast as possible after a lock-up. There's both a watchdog
+ implementation entirely in software (which can sometimes fail to
+ reboot the machine) and a driver for hardware watchdog boards, which
+ are more robust and can also keep track of the temperature inside
+ your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
+ in the kernel source.
+
+ The watchdog is usually used together with the watchdog daemon
+ which is available from
+ <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
+ also monitor NFS connections and can reboot the machine when the process
+ table is full.

+/*
+ * Theory of Operation:
+ * The Watch-Dog Timer is provided to ensure that standalone
+ * Systems can always recover from catastrophic conditions that
+ * caused the CPU to crash. This condition may have occured by
+ * external EMI or a software bug. When the CPU stops working
+ * correctly, hardware on the board will either perform a hardware
+ * reset (cold boot) or a non-maskable interrupt (NMI) to bring the
+ * system back to a known state.
+ *
+ * The Watch-Dog Timer is controlled by two I/O Ports.
+ * 443 hex - Read - Enable or refresh the Watch-Dog Timer
+ * 043 hex - Read - Disable the Watch-Dog Timer
+ *
+ * To enable the Watch-Dog Timer, a read from I/O port 443h must
+ * be performed. This will enable and activate the countdown timer
+ * which will eventually time out and either reset the CPU or cause
+ * an NMI depending on the setting of a jumper. To ensure that this
+ * reset condition does not occur, the Watch-Dog Timer must be
+ * periodically refreshed by reading the same I/O port 443h.
+ * The Watch-Dog Timer is disabled by reading I/O port 043h.
+ *
+ * The Watch-Dog Timer Time-Out Period is set via jumpers.
+ * It can be 1, 2, 10, 20, 110 or 220 seconds.

+ * ALi M7101 PMU Computer Watchdog Timer driver
+ *
+ * Based on w83877f_wdt.c by Scott Jennings <linuxdrivers@oro.net>
+ * and the Cobalt kernel WDT timer driver by Tim Hockin
+ * <thockin@cobaltnet.com>
+ *
+ * (c)2002 Steve Hill <steve@navaho.co.uk>
+ *
+ * This WDT driver is different from most other Linux WDT
+ * drivers in that the driver will ping the watchdog by itself,
+ * because this particular WDT has a very short timeout (1.6
+ * seconds) and it would be insane to count on any userspace
+ * daemon always getting scheduled within that time frame.
+ *
+ * Additions:
+ * Aug 23, 2004 - Added use_gpio module parameter for use on revision a1d PMUs
+ * found on very old cobalt hardware.
+ * -- Mike Waychison <michael.waychison@sun.com>

+ * For P4DPx:
+ * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
+ * This setting enables or disables Watchdog function. When enabled, the

+ * enough to load and run the OS. The application (service or driver) has
+ * to take over the control once OS is running up and before watchdog
+ * expires.
+ *
+ * 2. JUMPER
+ * For P4SBx: JP39
+ * For P4DPx: JP37
+ * This jumper is used for safety. Closed is enabled. This jumper
+ * prevents user enables watchdog in BIOS by accident.
+ *
+ * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
+ *
+ * The documentation lists motherboards P4SBx and P4DPx series as of
+ * 20-March-2002. However, this code works flawlessly with much newer
+ * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
+ *
+ * The original iTCO driver as written does not actually reset the
+ * watchdog timer on these machines, as a result they reboot after five
+ * minutes.
+ *
+ * NOTE: You may leave the Watchdog function disabled in the SuperMicro
+ * BIOS to avoid a "boot-race"... This driver will enable watchdog
+ * functionality even if it's disabled in the BIOS once the /dev/watchdog

+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system
+ * automatically and is defined at I/O port 0443H. To enable the
+ * watchdog timer and allow the system to reset, write I/O port 0443H.
+ * To disable the timer, write I/O port 0441H for the system to stop the
+ * watchdog function. The timer has a tolerance of 20% for its
+ * intervals.
+ *
+ * The following describes how the timer should be programmed.
+ *
+ * Enabling Watchdog:
+ * MOV AX,000FH (Choose the values from 0 to F)
+ * MOV DX,0443H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,000FH (Any value is fine.)
+ * MOV DX,0441H
+ * OUT DX,AX
+ *
+ * Watchdog timer control table:
+ * Level Value Time/sec | Level Value Time/sec
+ * 1 F 0 | 9 7 16

+ * PC Watchdog Driver
+ * by Ken Hollis (khollis@bitgate.com)
+ *
+ * Permission granted from Simon Machell (smachell@berkprod.com)
+ * Written for the Linux Kernel, and GPLed by Ken Hollis
+ *
+ * 960107 Added request_region routines, modulized the whole thing.
+ * 960108 Fixed end-of-file pointer (Thanks to Dan Hollis), added
+ * WD_TIMEOUT define.
+ * 960216 Added eof marker on the file, and changed verbose messages.
+ * 960716 Made functional and cosmetic changes to the source for
+ * inclusion in Linux 2.0.x kernels, thanks to Alan Cox.
+ * 960717 Removed read/seek routines, replaced with ioctl. Also, added
+ * check_region command due to Alan's suggestion.
+ * 960821 Made changes to compile in newer 2.0.x kernels. Added
+ * "cold reboot sense" entry.
+ * 960825 Made a few changes to code, deleted some defines and made
+ * typedefs to replace them. Made heartbeat reset only available
+ * via ioctl, and removed the write routine.
+ * 960828 Added new items for PC Watchdog Rev.C card.
+ * 960829 Changed around all of the IOCTLs, added new features,
+ * added watchdog disable/re-enable routines. Added firmware
+ * version reporting. Added read routine for temperature.
+ * Removed some extra defines, added an autodetect Revision
+ * routine.
+ * 961006 Revised some documentation, fixed some cosmetic bugs. Made
+ * drivers to panic the system if it's overheating at bootup.
+ * 961118 Changed some verbiage on some of the output, tidied up
+ * code bits, and added compatibility to 2.1.x.
+ * 970912 Enabled board on open and disable on close.
+ * 971107 Took account of recent VFS changes (broke read).
+ * 971210 Disable board on initialisation in case board already ticking.
+ * 971222 Changed open/close for temperature handling
+ * Michael Meskes <meskes@debian.org>.
+ * 980112 Used minor numbers from include/linux/miscdevice.h
+ * 990403 Clear reset status after reading control status register in
+ * pcwd_showprevstate(). [Marc Boucher <marc@mbsi.ca>]
+ * 990605 Made changes to code to support Firmware 1.22a, added
+ * fairly useless proc entry.
+ * 990610 removed said useless proc code for the merge <alan>
+ * 000403 Removed last traces of proc code. <davej>
+ * 011214 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT <Matt_Domsch@dell.com>
+ * Added timeout module option to override default

+ * 12/4 - 2000 [Initial revision]
+ * 25/4 - 2000 Added /dev/watchdog support
+ * 09/5 - 2001 [smj@oro.net] fixed fop_write to "return 1" on success
+ * 12/4 - 2002 [rob@osinvestor.com] eliminate fop_read
+ * fix possible wdt_is_open race
+ * add CONFIG_WATCHDOG_NOWAYOUT support
+ * remove lock_kernel/unlock_kernel pairs
+ * added KERN_* to printk's
+ * got rid of extraneous comments
+ * changed watchdog_info to correctly reflect what the driver offers
+ * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
+ * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
+ * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
+ * use module_param
+ * made timeout (the emulated heartbeat) a module_param
+ * made the keepalive ping an internal subroutine
+ * made wdt_stop and wdt_start module params
+ * added extra printk's for startup problems
+ * added MODULE_AUTHOR and MODULE_DESCRIPTION info
+ *
+ *
+ * This WDT driver is different from the other Linux WDT
+ * drivers in the following ways:
+ * *) The driver will ping the watchdog by itself, because this
+ * particular WDT has a very short timeout (one second) and it
+ * would be insane to count on any userspace daemon always
+ * getting scheduled within that time frame.

+ *
+ * Watchdog Timer Configuration
+ *
+ * The function of the watchdog timer is to reset the system automatically
+ * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
+ * and allow the system to reset, write appropriate values from the table
+ * below to I/O port 0120H and 0121H. To disable the timer, write a zero
+ * value to I/O port 0121H for the system to stop the watchdog function.
+ *
+ * The following describes how the timer should be programmed (according to
+ * the vendor documentation)
+ *
+ * Enabling Watchdog:
+ * MOV AX,000AH (enable, phase I)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000BH (enable, phase II)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000nH (set multiplier n, from 1-4)
+ * MOV DX,0120H
+ * OUT DX,AX
+ * MOV AX,000mH (set base timer m, from 0-F)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Reset timer:
+ * MOV AX,000mH (same as set base timer, above)
+ * MOV DX,0121H
+ * OUT DX,AX
+ *
+ * Disabling Watchdog:
+ * MOV AX,0000H (a zero value)
+ * MOV DX,0120H
+ * OUT DX,AX
+ *
+ * Watchdog timeout configuration values:
+ * N
+ * M | 1 2 3 4
+ * --|----------------------------------
+ * 0 | 0.5s 5s 50s 100s
+ * 1 | 1s 10s 100s 200s

+ *
+ * (c) Copyright 2001 Scott Jennings <linuxdrivers@oro.net>
+ * 9/27 - 2001 [Initial release]
+ *
+ * Additional fixes Alan Cox
+ * - Fixed formatting
+ * - Removed debug printks
+ * - Fixed SMP built kernel deadlock
+ * - Switched to private locks not lock_kernel
+ * - Used ioremap/writew/readw
+ * - Added NOWAYOUT support
+ * 4/12 - 2002 Changes by Rob Radez <rob@osinvestor.com>
+ * - Change comments
+ * - Eliminate fop_llseek
+ * - Change CONFIG_WATCHDOG_NOWAYOUT semantics
+ * - Add KERN_* tags to printks
+ * - fix possible wdt_is_open race
+ * - Report proper capabilities in watchdog_info
+ * - Add WDIOC_{GETSTATUS, GETBOOTSTATUS, SETTIMEOUT,
+ * GETTIMEOUT, SETOPTIONS} ioctls
+ * 09/8 - 2003 Changes by Wim Van Sebroeck <wim@iguana.be>
+ * - cleanup of trailing spaces
+ * - added extra printk's for startup problems
+ * - use module_param
+ * - made timeout (the emulated heartbeat) a module_param
+ * - made the keepalive ping an internal subroutine
+ * 3/27 - 2004 Changes by Sean Young <sean@mess.org>
+ * - set MMCR_BASE to 0xfffef000
+ * - CBAR does not need to be read
+ * - removed debugging printks
+ *
+ * This WDT driver is different from most other Linux WDT
+ * drivers in that the driver will ping the watchdog by itself,
+ * because this particular WDT has a very short timeout (1.6
+ * seconds) and it would be insane to count on any userspace
+ * daemon always getting scheduled within that time frame.
+ *
+ * This driver uses memory mapped IO, and spinlock.

+ * As a result of this timing problem, the only modes that are particularly
+ * feasible are the 4096 and the 2048 divisors, which yeild 5.25 and 2.62ms
+ * overflow periods respectively.
+ *
+ * Also, since we can't really expect userspace to be responsive enough
+ * before the overflow happens, we maintain two seperate timers .. One in
+ * the kernel for clearing out WOVF every 2ms or so (again, this depends on
+ * HZ == 1000), and another for monitoring userspace writes to the WDT device.
+ *
+ * As such, we currently use a configurable heartbeat interval which defaults

+ * History:
+ * 2003 - Created version 1.0 for Linux 2.4.x.
+ * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
+ * features. Released version 1.1
+ *
+ * Theory of operation:
+ *
+ * A Watchdog Timer (WDT) is a hardware circuit that can
+ * reset the computer system in case of a software fault.
+ * You probably knew that already.
+ *
+ * Usually a userspace daemon will notify the kernel WDT driver
+ * via the /dev/watchdog special device file that userspace is
+ * still alive, at regular intervals. When such a notification
+ * occurs, the driver will usually tell the hardware watchdog
+ * that everything is in order, and that the watchdog should wait
+ * for yet another little while to reset the system.
+ * If userspace fails (RAM error, kernel bug, whatever), the
+ * notifications cease to occur, and the hardware watchdog will
+ * reset the system (causing a reboot) after the timeout occurs.
+ *
+ * Create device with:
+ * mknod /dev/watchdog c 10 130
+ *
+ * For an example userspace keep-alive daemon, see:
+ * Documentation/watchdog/watchdog.txt

+ * (c) Copyright 2001 Scott Jennings <linuxdrivers@oro.net>
+ *
+ * 4/19 - 2001 [Initial revision]
+ * 9/27 - 2001 Added spinlocking
+ * 4/12 - 2002 [rob@osinvestor.com] Eliminate extra comments
+ * Eliminate fop_read
+ * Eliminate extra spin_unlock
+ * Added KERN_* tags to printks
+ * add CONFIG_WATCHDOG_NOWAYOUT support
+ * fix possible wdt_is_open race
+ * changed watchdog_info to correctly reflect what the driver offers
+ * added WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS, WDIOC_SETTIMEOUT,
+ * WDIOC_GETTIMEOUT, and WDIOC_SETOPTIONS ioctls
+ * 09/8 - 2003 [wim@iguana.be] cleanup of trailing spaces
+ * added extra printk's for startup problems
+ * use module_param
+ * made timeout (the emulated heartbeat) a module_param
+ * made the keepalive ping an internal subroutine
+ *
+ * This WDT driver is different from most other Linux WDT
+ * drivers in that the driver will ping the watchdog by itself,
+ * because this particular WDT has a very short timeout (1.6
+ * seconds) and it would be insane to count on any userspace
+ * daemon always getting scheduled within that time frame.

+------------
+Fix memory leak in statfs when mounted to very old servers (e.g.
+Windows 9x). Add new feature "POSIX open" which allows servers
+which support the current POSIX Extensions to provide better semantics
+(e.g. delete for open files opened with posix open). Take into
+account umask on posix mkdir not just older style mkdir. Add
+ability to mount to IPC$ share (which allows CIFS named pipes to be
+opened, read and written as if they were files). When 1st tree
+connect fails (e.g. due to signing negotiation failure) fix
+leak that causes cifsd not to stop and rmmod to fail to cleanup
+cifs_request_buffers pool. Fix problem with POSIX Open/Mkdir on
+bigendian architectures. Fix possible memory corruption when
+EAGAIN returned on kern_recvmsg. Return better error if server
+requires packet signing but client has disabled it.
+
Version 1.50
------------
Fix NTLMv2 signing. NFS server mounted over cifs works (if cifs mount is
Samba supports newer POSIX CIFS Protocol Extensions). Add "nounix"
mount option to allow disabling the CIFS Unix Extensions for just
that mount. Fix hang on spinlock in find_writable_file (race when
-reopening file after session crash).
+reopening file after session crash). Byte range unlock request to
+windows server could unlock more bytes (on server copy of file)
+than intended if start of unlock request is well before start of
+a previous byte range lock that we issued.

- * struct pm_ops - Callbacks for managing platform dependent system sleep
- * states.
- *
- * @valid: Callback to determine if given system sleep state is supported by
- * the platform.
- * Valid (ie. supported) states are advertised in /sys/power/state. Note
- * that it still may be impossible to enter given system sleep state if the
- * conditions aren't right.
- * There is the %pm_valid_only_mem function available that can be assigned
- * to this if the platform only supports mem sleep.
- *
- * @set_target: Tell the platform which system sleep state is going to be
- * entered.
- * @set_target() is executed right prior to suspending devices. The
- * information conveyed to the platform code by @set_target() should be
- * disregarded by the platform as soon as @finish() is executed and if
- * @prepare() fails. If @set_target() fails (ie. returns nonzero),
- * @prepare(), @enter() and @finish() will not be called by the PM core.
- * This callback is optional. However, if it is implemented, the argument
- * passed to @prepare(), @enter() and @finish() is meaningless and should
- * be ignored.
- *
- * @prepare: Prepare the platform for entering the system sleep state indicated
- * by @set_target() or represented by the argument if @set_target() is not
- * implemented.
- * @prepare() is called right after devices have been suspended (ie. the
- * appropriate .suspend() method has been executed for each device) and
- * before the nonboot CPUs are disabled (it is executed with IRQs enabled).
- * This callback is optional. It returns 0 on success or a negative
- * error code otherwise, in which case the system cannot enter the desired
- * sleep state (@enter() and @finish() will not be called in that case).
- *
- * @enter: Enter the system sleep state indicated by @set_target() or
- * represented by the argument if @set_target() is not implemented.
- * This callback is mandatory. It returns 0 on success or a negative
- * error code otherwise, in which case the system cannot enter the desired
- * sleep state.
- *
- * @finish: Called when the system has just left a sleep state, right after
- * the nonboot CPUs have been enabled and before devices are resumed (it is
- * executed with IRQs enabled). If @set_target() is not implemented, the
- * argument represents the sleep state being left.
- * This callback is optional, but should be implemented by the platforms
- * that implement @prepare(). If implemented, it is always called after
- * @enter() (even if @enter() fails).

+ * @set_target: Tell the platform which system sleep state is going to be

+ * @set_target() is executed right prior to suspending devices. The
+ * information conveyed to the platform code by @set_target() should be
+ * disregarded by the platform as soon as @finish() is executed and if
+ * @prepare() fails. If @set_target() fails (ie. returns nonzero),
+ * @prepare(), @enter() and @finish() will not be called by the PM core.
+ * This callback is optional. However, if it is implemented, the argument
+ * passed to @enter() is meaningless and should be ignored.
+ *
+ * @prepare: Prepare the platform for entering the system sleep state indicated
+ * by @set_target().
+ * @prepare() is called right after devices have been suspended (ie. the
+ * appropriate .suspend() method has been executed for each device) and
+ * before the nonboot CPUs are disabled (it is executed with IRQs enabled).
+ * This callback is optional. It returns 0 on success or a negative
+ * error code otherwise, in which case the system cannot enter the desired
+ * sleep state (@enter() and @finish() will not be called in that case).
+ *
+ * @enter: Enter the system sleep state indicated by @set_target() or
+ * represented by the argument if @set_target() is not implemented.
+ * This callback is mandatory. It returns 0 on success or a negative
+ * error code otherwise, in which case the system cannot enter the desired
+ * sleep state.
+ *
+ * @finish: Called when the system has just left a sleep state, right after
+ * the nonboot CPUs have been enabled and before devices are resumed (it is
+ * executed with IRQs enabled).

+ * There is one global cgroup mutex. We also require taking

+ * See "The task_lock() exception", at the end of this comment.
+ *
+ * A task must hold cgroup_mutex to modify cgroups.
+ *
+ * Any task can increment and decrement the count field without lock.
+ * So in general, code holding cgroup_mutex can't rely on the count
+ * field not changing. However, if the count goes to zero, then only
+ * attach_task() can increment it again. Because a count of zero
+ * means that no tasks are currently attached, therefore there is no
+ * way a task attached to that cgroup can fork (the other way to
+ * increment the count). So code holding cgroup_mutex can safely
+ * assume that if the count is zero, it will stay zero. Similarly, if
+ * a task holds cgroup_mutex on a cgroup with zero count, it
+ * knows that the cgroup won't be removed, as cgroup_rmdir()
+ * needs that mutex.
+ *
+ * The cgroup_common_file_write handler for operations that modify
+ * the cgroup hierarchy holds cgroup_mutex across the entire operation,
+ * single threading all such cgroup modifications across the system.
+ *
+ * The fork and exit callbacks cgroup_fork() and cgroup_exit(), don't
+ * (usually) take cgroup_mutex. These are the two most performance
+ * critical pieces of code here. The exception occurs on cgroup_exit(),
+ * when a task in a notify_on_release cgroup exits. Then cgroup_mutex
+ * is taken, and if the cgroup count is zero, a usermode call made
+ * to /sbin/cgroup_release_agent with the name of the cgroup (path
+ * relative to the root of cgroup file system) as the argument.
+ *
+ * A cgroup can only be deleted if both its 'count' of using tasks
+ * is zero, and its list of 'children' cgroups is empty. Since all
+ * tasks in the system use _some_ cgroup, and since there is always at
+ * least one task in the system (init, pid == 1), therefore, top_cgroup
+ * always has either children cgroups and/or using tasks. So we don't
+ * need a special hack to ensure that top_cgroup cannot be deleted.
+ *
+ * The task_lock() exception
+ *
+ * The need for this exception arises from the action of
+ * attach_task(), which overwrites one tasks cgroup pointer with
+ * another. It does so using cgroup_mutexe, however there are
+ * several performance critical places that need to reference
+ * task->cgroup without the expense of grabbing a system global
+ * mutex. Therefore except as noted below, when dereferencing or, as
+ * in attach_task(), modifying a task'ss cgroup pointer we use
+ * task_lock(), which acts on a spinlock (task->alloc_lock) already in
+ * the task_struct routinely used for such matters.
+ *
+ * P.S. One more locking exception. RCU is used to guard the
+ * update of a tasks cgroup pointer by attach_task()

+ * See "What is sched_load_balance" in Documentation/cpusets.txt
+ * for a background explanation of this.
+ *

+ * Must not be called holding callback_mutex, because we must not
+ * call lock_cpu_hotplug() while holding callback_mutex. Elsewhere
+ * the kernel nests callback_mutex inside lock_cpu_hotplug() calls.
+ * So the reverse nesting would risk an ABBA deadlock.
+ *
+ * The three key local variables below are:
+ * q - a kfifo queue of cpuset pointers, used to implement a
+ * top-down scan of all cpusets. This scan loads a pointer
+ * to each cpuset marked is_sched_load_balance into the
+ * array 'csa'. For our purposes, rebuilding the schedulers
+ * sched domains, we can ignore !is_sched_load_balance cpusets.
+ * csa - (for CpuSet Array) Array of pointers to all the cpusets
+ * that need to be load balanced, for convenient iterative
+ * access by the subsequent code that finds the best partition,
+ * i.e the set of domains (subsets) of CPUs such that the
+ * cpus_allowed of every cpuset marked is_sched_load_balance
+ * is a subset of one of these domains, while there are as
+ * many such domains as possible, each as small as possible.
+ * doms - Conversion of 'csa' to an array of cpumasks, for passing to
+ * the kernel/sched.c routine partition_sched_domains() in a
+ * convenient format, that can be easily compared to the prior
+ * value to determine what partition elements (sched domains)
+ * were changed (added or removed.)
+ *
+ * Finding the best partition (set of domains):
+ * The triple nested loops below over i, j, k scan over the
+ * load balanced cpusets (using the array of cpuset pointers in
+ * csa[]) looking for pairs of cpusets that have overlapping
+ * cpus_allowed, but which don't have the same 'pn' partition
+ * number and gives them in the same partition number. It keeps
+ * looping on the 'restart' label until it can no longer find
+ * any such pairs.
+ *
+ * The union of the cpus_allowed masks from the set of
+ * all cpusets having the same 'pn' value then form the one
+ * element of the partition (one sched domain) to be passed to

- * cpuset_exit - detach cpuset from exiting task
- * @tsk: pointer to task_struct of exiting process
- *
- * Description: Detach cpuset from @tsk and release it.
- *
- * Note that cpusets marked notify_on_release force every task in
- * them to take the global manage_mutex mutex when exiting.
- * This could impact scaling on very large systems. Be reluctant to
- * use notify_on_release cpusets where very high task exit scaling
- * is required on large systems.
- *
- * Don't even think about derefencing 'cs' after the cpuset use count
- * goes to zero, except inside a critical section guarded by manage_mutex
- * or callback_mutex. Otherwise a zero cpuset use count is a license to
- * any other task to nuke the cpuset immediately, via cpuset_rmdir().
- *
- * This routine has to take manage_mutex, not callback_mutex, because
- * it is holding that mutex while calling check_for_release(),
- * which calls kmalloc(), so can't be called holding callback_mutex().
- *
- * the_top_cpuset_hack:
- *
- * Set the exiting tasks cpuset to the root cpuset (top_cpuset).
- *
- * Don't leave a task unable to allocate memory, as that is an
- * accident waiting to happen should someone add a callout in
- * do_exit() after the cpuset_exit() call that might allocate.
- * If a task tries to allocate memory with an invalid cpuset,
- * it will oops in cpuset_update_task_memory_state().
- *
- * We call cpuset_exit() while the task is still competent to
- * handle notify_on_release(), then leave the task attached to
- * the root cpuset (top_cpuset) for the remainder of its exit.
- *
- * To do this properly, we would increment the reference count on
- * top_cpuset, and near the very end of the kernel/exit.c do_exit()
- * code we would add a second cpuset function call, to drop that
- * reference. This would just create an unnecessary hot spot on
- * the top_cpuset reference count, to no avail.
- *
- * Normally, holding a reference to a cpuset without bumping its
- * count is unsafe. The cpuset could go away, or someone could
- * attach us to a different cpuset, decrementing the count on
- * the first cpuset that we never incremented. But in this case,
- * top_cpuset isn't going away, and either task has PF_EXITING set,
- * which wards off any attach_task() attempts, or task is a failed
- * fork, never visible to attach_task.
- *
- * Another way to do this would be to set the cpuset pointer
- * to NULL here, and check in cpuset_update_task_memory_state()
- * for a NULL pointer. This hack avoids that NULL check, for no
- * cost (other than this way too long comment ;).

- * linux/sound/oss/dmasound/dmasound_awacs.c

- * PowerMac `AWACS' and `Burgundy' DMA Sound Driver
- * with some limited support for DACA & Tumbler
- *
- * See linux/sound/oss/dmasound/dmasound_core.c for copyright and
- * history prior to 2001/01/26.
- *
- * 26/01/2001 ed 0.1 Iain Sandoe
- * - added version info.
- * - moved dbdma command buffer allocation to PMacXXXSqSetup()
- * - fixed up beep dbdma cmd buffers
- *
- * 08/02/2001 [0.2]
- * - make SNDCTL_DSP_GETFMTS return the correct info for the h/w
- * - move soft format translations to a separate file
- * - [0.3] make SNDCTL_DSP_GETCAPS return correct info.
- * - [0.4] more informative machine name strings.
- * - [0.5]
- * - record changes.
- * - made the default_hard/soft entries.
- * 04/04/2001 [0.6]
- * - minor correction to bit assignments in awacs_defs.h
- * - incorporate mixer changes from 2.2.x back-port.
- * - take out passthru as a rec input (it isn't).
- * - make Input Gain slider work the 'right way up'.
- * - try to make the mixer sliders more logical - so now the
- * input selectors are just two-state (>50% == ON) and the
- * Input Gain slider handles the rest of the gain issues.
- * - try to pick slider representations that most closely match
- * the actual use - e.g. IGain for input gain...
- * - first stab at over/under-run detection.
- * - minor cosmetic changes to IRQ identification.
- * - fix bug where rates > max would be reported as supported.
- * - first stab at over/under-run detection.
- * - make use of i2c for mixer settings conditional on perch
- * rather than cuda (some machines without perch have cuda).
- * - fix bug where TX stops when dbdma status comes up "DEAD"
- * so far only reported on PowerComputing clones ... but.
- * - put in AWACS/Screamer register write timeouts.
- * - part way to partitioning the init() stuff
- * - first pass at 'tumbler' stuff (not support - just an attempt
- * to allow the driver to load on new G4s).
- * 01/02/2002 [0.7] - BenH
- * - all sort of minor bits went in since the latest update, I
- * bumped the version number for that reason
- *
- * 07/26/2002 [0.8] - BenH
- * - More minor bits since last changelog (I should be more careful
- * with those)
- * - Support for snapper & better tumbler integration by Toby Sargeant
- * - Headphone detect for scremer by Julien Blache
- * - More tumbler fixed by Andreas Schwab
- * 11/29/2003 [0.8.1] - Renzo Davoli (King Enzo)
- * - Support for Snapper line in
- * - snapper input resampling (for rates < 44100)
- * - software line gain control

- * Special thanks to Ensoniq
- *
- * Supported devices:
- * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
- * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
- * /dev/dsp1 additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- * /dev/midi simple MIDI UART interface, no ioctl
- *
- * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- * there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- * Revision history
- * 04.06.1998 0.1 Initial release
- * Mixer stuff should be overhauled; especially optional AC97 mixer bits
- * should be detected. This results in strange behaviour of some mixer
- * settings, like master volume and mic.
- * 08.06.1998 0.2 First release using Alan Cox' soundcore instead of miscdevice
- * 03.08.1998 0.3 Do not include modversions.h
- * Now mixer behaviour can basically be selected between
- * "OSS documented" and "OSS actual" behaviour
- * 31.08.1998 0.4 Fix realplayer problems - dac.count issues
- * 27.10.1998 0.5 Fix joystick support
- * -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- * 10.12.1998 0.6 Fix drain_dac trying to wait on not yet initialized DMA
- * 23.12.1998 0.7 Fix a few f_file & FMODE_ bugs
- * Don't wake up app until there are fragsize bytes to read/write
- * 06.01.1999 0.8 remove the silly SA_INTERRUPT flag.
- * hopefully killed the egcs section type conflict
- * 12.03.1999 0.9 cinfo.blocks should be reset after GETxPTR ioctl.
- * reported by Johan Maes <joma@telindus.be>
- * 22.03.1999 0.10 return EAGAIN instead of EBUSY when O_NONBLOCK
- * read/write cannot be executed
- * 07.04.1999 0.11 implemented the following ioctl's: SOUND_PCM_READ_RATE,
- * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
- * Alpha fixes reported by Peter Jones <pjones@redhat.com>
- * Another Alpha fix (wait_src_ready in init routine)
- * reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- * Note: joystick address handling might still be wrong on archs
- * other than i386
- * 15.06.1999 0.12 Fix bad allocation bug.
- * Thanks to Deti Fliegl <fliegl@in.tum.de>
- * 28.06.1999 0.13 Add pci_set_master
- * 03.08.1999 0.14 adapt to Linus' new __setup/__initcall
- * added kernel command line option "es1371=joystickaddr"
- * removed CONFIG_SOUND_ES1371_JOYPORT_BOOT kludge
- * 10.08.1999 0.15 (Re)added S/PDIF module option for cards revision >= 4.
- * Initial version by Dave Platt <dplatt@snulbug.mtview.ca.us>.
- * module_init/__setup fixes
- * 08.16.1999 0.16 Joe Cotellese <joec@ensoniq.com>
- * Added detection for ES1371 revision ID so that we can
- * detect the ES1373 and later parts.
- * added AC97 #defines for readability
- * added a /proc file system for dumping hardware state
- * updated SRC and CODEC w/r functions to accommodate bugs
- * in some versions of the ES137x chips.
- * 31.08.1999 0.17 add spin_lock_init
- * replaced current->state = x with set_current_state(x)
- * 03.09.1999 0.18 change read semantics for MIDI to match
- * OSS more closely; remove possible wakeup race
- * 21.10.1999 0.19 Round sampling rates, requested by
- * Kasamatsu Kenichi <t29w0267@ip.media.kyoto-u.ac.jp>
- * 27.10.1999 0.20 Added SigmaTel 3D enhancement string
- * Codec ID printing changes
- * 28.10.1999 0.21 More waitqueue races fixed
- * Joe Cotellese <joec@ensoniq.com>
- * Changed PCI detection routine so we can more easily
- * detect ES137x chip and derivatives.
- * 05.01.2000 0.22 Should now work with rev7 boards; patch by
- * Eric Lemar, elemar@cs.washington.edu
- * 08.01.2000 0.23 Prevent some ioctl's from returning bad count values on underrun/overrun;
- * Tim Janik's BSE (Bedevilled Sound Engine) found this
- * 07.02.2000 0.24 Use pci_alloc_consistent and pci_register_driver
- * 07.02.2000 0.25 Use ac97_codec
- * 01.03.2000 0.26 SPDIF patch by Mikael Bouillot <mikael.bouillot@bigfoot.com>
- * Use pci_module_init
- * 21.11.2000 0.27 Initialize dma buffers in poll, otherwise poll may return a bogus mask
- * 12.12.2000 0.28 More dma buffer initializations, patch from
- * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
