The CONFIG_RCU_CPU_STALL_DETECTOR kernel config parameter enables
RCU's CPU stall detector, which detects conditions that unduly delay
RCU grace periods. The stall detector's idea of what constitutes
-"unduly delayed" is controlled by a pair of C preprocessor macros:
+"unduly delayed" is controlled by a set of C preprocessor macros:
RCU_SECONDS_TILL_STALL_CHECK
This macro defines the period of time that RCU will wait from
the beginning of a grace period until it issues an RCU CPU
- stall warning. It is normally ten seconds.
+ stall warning. This time period is normally ten seconds.
RCU_SECONDS_TILL_STALL_RECHECK

- issuing a stall warning until it issues another stall warning.
- It is normally set to thirty seconds.
+ issuing a stall warning until it issues another stall warning
+ for the same stall. This time period is normally set to thirty
+ seconds.
RCU_STALL_RAT_DELAY
- The CPU stall detector tries to make the offending CPU rat on itself,
- as this often gives better-quality stack traces. However, if
- the offending CPU does not detect its own stall in the number
- of jiffies specified by RCU_STALL_RAT_DELAY, then other CPUs will
- complain. This is normally set to two jiffies.
+ The CPU stall detector tries to make the offending CPU print its
+ own warnings, as this often gives better-quality stack traces.
+ However, if the offending CPU does not detect its own stall in
+ the number of jiffies specified by RCU_STALL_RAT_DELAY, then
+ some other CPU will complain. This delay is normally set to
+ two jiffies.
-The following problems can result in an RCU CPU stall warning:
+When a CPU detects that it is stalling, it will print a message similar
+to the following:
+
+INFO: rcu_sched_state detected stall on CPU 5 (t=2500 jiffies)
+
+This message indicates that CPU 5 detected that it was causing a stall,
+and that the stall was affecting RCU-sched. This message will normally be
+followed by a stack dump of the offending CPU. On TREE_RCU kernel builds,
+RCU and RCU-sched are implemented by the same underlying mechanism,
+while on TREE_PREEMPT_RCU kernel builds, RCU is instead implemented
+by rcu_preempt_state.
+
+On the other hand, if the offending CPU fails to print out a stall-warning
+message quickly enough, some other CPU will print a message similar to
+the following:
+
+INFO: rcu_bh_state detected stalls on CPUs/tasks: { 3 5 } (detected by 2, 2502 jiffies)
+
+This message indicates that CPU 2 detected that CPUs 3 and 5 were both
+causing stalls, and that the stall was affecting RCU-bh. This message
+will normally be followed by stack dumps for each CPU. Please note that
+TREE_PREEMPT_RCU builds can be stalled by tasks as well as by CPUs,
+and that the tasks will be indicated by PID, for example, "P3421".
+It is even possible for a rcu_preempt_state stall to be caused by both
+CPUs -and- tasks, in which case the offending CPUs and tasks will all
+be called out in the list.
+
+Finally, if the grace period ends just as the stall warning starts
+printing, there will be a spurious stall-warning message:
+
+INFO: rcu_bh_state detected stalls on CPUs/tasks: { } (detected by 4, 2502 jiffies)
+
+This is rare, but does happen from time to time in real life.
+
+So your kernel printed an RCU CPU stall warning. The next question is
+"What caused it?" The following problems can result in RCU CPU stall
+warnings:
o A CPU looping in an RCU read-side critical section.
-o A CPU looping with interrupts disabled.
+o A CPU looping with interrupts disabled. This condition can
+ result in RCU-sched and RCU-bh stalls.
-o A CPU looping with preemption disabled.
+o A CPU looping with preemption disabled. This condition can
+ result in RCU-sched stalls and, if ksoftirqd is in use, RCU-bh
+ stalls.
+
+o A CPU looping with bottom halves disabled. This condition can
+ result in RCU-sched and RCU-bh stalls.
o For !CONFIG_PREEMPT kernels, a CPU looping anywhere in the kernel
without invoking schedule().
o A bug in the RCU implementation.
o A hardware failure. This is quite unlikely, but has occurred
- at least once in a former life. A CPU failed in a running system,
+ at least once in real life. A CPU failed in a running system,
becoming unresponsive, but not causing an immediate crash.
This resulted in a series of RCU CPU stall warnings, eventually
leading the realization that the CPU had failed.
-The RCU, RCU-sched, and RCU-bh implementations have CPU stall warning.
-SRCU does not do so directly, but its calls to synchronize_sched() will
-result in RCU-sched detecting any CPU stalls that might be occurring.
-
-To diagnose the cause of the stall, inspect the stack traces. The offending
-function will usually be near the top of the stack. If you have a series
-of stall warnings from a single extended stall, comparing the stack traces
-can often help determine where the stall is occurring, which will usually
-be in the function nearest the top of the stack that stays the same from
-trace to trace.

RCU bugs can often be debugged with the help of CONFIG_RCU_TRACE.

+When: 2.6.35
+Files: drivers/media/video/saa5246a.c drivers/media/video/saa5249.c
+ include/linux/videotext.h
+Why: The vtx device nodes have been superseded by vbi device nodes
+ for many years. No applications exist that use the vtx support.
+ Of the two i2c drivers that actually support this API the saa5249
+ has been impossible to use for a year now and no known hardware
+ that supports this device exists. The saa5246a is theoretically
+ supported by the old mxb boards, but it never actually worked.
+
+ In summary: there is no hardware that can use this API and there
+ are no applications actually implementing this API.
+
+ The vtx support still reserves minors 192-223 and we would really
+ like to reuse those for upcoming new functionality. In the unlikely
+ event that new hardware appears that wants to use the functionality
+ provided by the vtx API, then that functionality should be build
+ around the sliced VBI API instead.

sysctl(8)), Kprobes tries to reduce probe-hit overhead by using a jump
instruction instead of a breakpoint instruction at each probepoint.
using one of the following techniques:
- Specify an empty function for the kprobe's post_handler or break_handler.
or
-- Config CONFIG_OPTPROBES=n.
- or
- Execute 'sysctl -w debug.kprobes_optimization=n'
2. Architectures Supported
so you can use "objdump -d -l vmlinux" to see the source-to-object
code mapping.
-If you want to reduce probing overhead, set "Kprobes jump optimization
-support" (CONFIG_OPTPROBES) to "y". You can find this option under the
-"Kprobes" line.
-
4. API Reference
The Kprobes API includes a "register" function and an "unregister"
desirable to first provide fair CPU time to each user on the system and then to
each task belonging to a user.
-CONFIG_GROUP_SCHED strives to achieve exactly that. It lets tasks to be
+CONFIG_CGROUP_SCHED strives to achieve exactly that. It lets tasks to be
grouped and divides CPU time fairly among such groups.
CONFIG_RT_GROUP_SCHED permits to group real-time (i.e., SCHED_FIFO and
CONFIG_FAIR_GROUP_SCHED permits to group CFS (i.e., SCHED_NORMAL and
SCHED_BATCH) tasks.
-At present, there are two (mutually exclusive) mechanisms to group tasks for
-CPU bandwidth control purposes:
-
- - Based on user id (CONFIG_USER_SCHED)
-
- With this option, tasks are grouped according to their user id.
-
- - Based on "cgroup" pseudo filesystem (CONFIG_CGROUP_SCHED)
-
- This options needs CONFIG_CGROUPS to be defined, and lets the administrator
+ These options need CONFIG_CGROUPS to be defined, and let the administrator
create arbitrary groups of tasks, using the "cgroup" pseudo filesystem. See
Documentation/cgroups/cgroups.txt for more information about this filesystem.
-Only one of these options to group tasks can be chosen and not both.
-
-When CONFIG_USER_SCHED is defined, a directory is created in sysfs for each new
-user and a "cpu_share" file is added in that directory.
-
- # cd /sys/kernel/uids
- # cat 512/cpu_share # Display user 512's CPU share
- 1024
- # echo 2048 > 512/cpu_share # Modify user 512's CPU share
- # cat 512/cpu_share # Display user 512's CPU share
- 2048
- #
-
-CPU bandwidth between two users is divided in the ratio of their CPU shares.
-For example: if you would like user "root" to get twice the bandwidth of user
-"guest," then set the cpu_share for both the users such that "root"'s cpu_share
-is twice "guest"'s cpu_share.
-

-User namespaces are intended to be hierarchical. But they are currently
-only partially implemented. Each of those has ramifications for CFS.
-
-First, since user namespaces are hierarchical, the /sys/kernel/uids
-presentation is inadequate. Eventually we will likely want to use sysfs
-tagging to provide private views of /sys/kernel/uids within each user
-namespace.
-
-Second, the hierarchical nature is intended to support completely
-unprivileged use of user namespaces. So if using user groups, then
-we want the users in a user namespace to be children of the user
-who created it.
-
-That is currently unimplemented. So instead, every user in a new
-user namespace will receive 1024 shares just like any user in the
-initial user namespace. Note that at the moment creation of a new
-user namespace requires each of CAP_SYS_ADMIN, CAP_SETUID, and
-CAP_SETGID.
2.3 Basis for grouping tasks
----------------------------
-There are two compile-time settings for allocating CPU bandwidth. These are
-configured using the "Basis for grouping tasks" multiple choice menu under
-General setup > Group CPU Scheduler:
-
-a. CONFIG_USER_SCHED (aka "Basis for grouping tasks" = "user id")
-
-This lets you use the virtual files under
-"/sys/kernel/uids/<uid>/cpu_rt_runtime_us" to control he CPU time reserved for
-each user .
-
-The other option is:
-
-.o CONFIG_CGROUP_SCHED (aka "Basis for grouping tasks" = "Control groups")
+Enabling CONFIG_RT_GROUP_SCHED lets you explicitly allocate real
+CPU bandwidth to task groups.
This uses the /cgroup virtual file system and
"/cgroup/<cgroup>/cpu.rt_runtime_us" to control the CPU time reserved for each
-control group instead.
+control group.
For more information on working with control groups, you should read
Documentation/cgroups/cgroups.txt as well.
===============
There is work in progress to make the scheduling period for each group
-("/sys/kernel/uids/<uid>/cpu_rt_period_us" or
-"/cgroup/<cgroup>/cpu.rt_period_us" respectively) configurable as well.
+("/cgroup/<cgroup>/cpu.rt_period_us") configurable as well.
The constraint on the period is that a subgroup must have a smaller or
equal period to its parent. But realistically its not very useful _yet_

3. Defining an event-enabled tracepoint
=======================================
to be traced. Echoing names of functions into this file
will limit the trace to only those functions.
+ This interface also allows for commands to be used. See the
+ "Filter commands" section for more details.
+
set_ftrace_notrace:
This has an effect opposite to that of
can either use the sysctl function or set it via the proc system
interface.
- sysctl kernel.ftrace_dump_on_oops=1
+ sysctl kernel.ftrace_dump_on_oops=n
or
- echo 1 > /proc/sys/kernel/ftrace_dump_on_oops
+ echo n > /proc/sys/kernel/ftrace_dump_on_oops
+If n = 1, ftrace will dump buffers of all CPUs, if n = 2 ftrace will
+only dump the buffer of the CPU that triggered the oops.
Here's an example of such a dump after a null pointer
dereference in a kernel module:
echo > set_graph_function
+Filter commands
+---------------
+
+A few commands are supported by the set_ftrace_filter interface.
+Trace commands have the following format:
+
+<function>:<command>:<parameter>
+
+The following commands are supported:
+
+- mod
+ This command enables function filtering per module. The
+ parameter defines the module. For example, if only the write*
+ functions in the ext3 module are desired, run:
+
+ echo 'write*:mod:ext3' > set_ftrace_filter
+
+ This command interacts with the filter in the same way as
+ filtering based on function names. Thus, adding more functions
+ in a different module is accomplished by appending (>>) to the
+ filter file. Remove specific module functions by prepending
+ '!':
+
+ echo '!writeback*:mod:ext3' >> set_ftrace_filter
+
+- traceon/traceoff
+ These commands turn tracing on and off when the specified
+ functions are hit. The parameter determines how many times the
+ tracing system is turned on and off. If unspecified, there is
+ no limit. For example, to disable tracing when a schedule bug
+ is hit the first 5 times, run:
+
+ echo '__schedule_bug:traceoff:5' > set_ftrace_filter
+
+ These commands are cumulative whether or not they are appended
+ to set_ftrace_filter. To remove a command, prepend it by '!'
+ and drop the parameter:
+
+ echo '!__schedule_bug:traceoff' > set_ftrace_filter
+
+
