++Introduction:
++-------------
++
++The module hwlat_detector is a special purpose kernel module that is used to
++detect large system latencies induced by the behavior of certain underlying
++hardware or firmware, independent of Linux itself. The code was developed
++originally to detect SMIs (System Management Interrupts) on x86 systems,
++however there is nothing x86 specific about this patchset. It was
++originally written for use by the "RT" patch since the Real Time
++kernel is highly latency sensitive.
++
++SMIs are usually not serviced by the Linux kernel, which typically does not
++even know that they are occuring. SMIs are instead are set up by BIOS code
++and are serviced by BIOS code, usually for "critical" events such as
++management of thermal sensors and fans. Sometimes though, SMIs are used for
++other tasks and those tasks can spend an inordinate amount of time in the
++handler (sometimes measured in milliseconds). Obviously this is a problem if
++you are trying to keep event service latencies down in the microsecond range.
++
++The hardware latency detector works by hogging all of the cpus for configurable
++amounts of time (by calling stop_machine()), polling the CPU Time Stamp Counter
++for some period, then looking for gaps in the TSC data. Any gap indicates a
++time when the polling was interrupted and since the machine is stopped and
++interrupts turned off the only thing that could do that would be an SMI.
++
++Note that the SMI detector should *NEVER* be used in a production environment.
++It is intended to be run manually to determine if the hardware platform has a
++problem with long system firmware service routines.
++
++Usage:
++------
++
++Loading the module hwlat_detector passing the parameter "enabled=1" (or by
++setting the "enable" entry in "hwlat_detector" debugfs toggled on) is the only
++step required to start the hwlat_detector. It is possible to redefine the
++threshold in microseconds (us) above which latency spikes will be taken
++into account (parameter "threshold=").
++
++Example:
++
++ # modprobe hwlat_detector enabled=1 threshold=100
++
++After the module is loaded, it creates a directory named "hwlat_detector" under
++the debugfs mountpoint, "/debug/hwlat_detector" for this text. It is necessary
++to have debugfs mounted, which might be on /sys/debug on your system.
++
++The /debug/hwlat_detector interface contains the following files:
++
++count - number of latency spikes observed since last reset
++enable - a global enable/disable toggle (0/1), resets count
++max - maximum hardware latency actually observed (usecs)
++sample - a pipe from which to read current raw sample data
++ in the format <timestamp> <latency observed usecs>
++ (can be opened O_NONBLOCK for a single sample)
++threshold - minimum latency value to be considered (usecs)
++width - time period to sample with CPUs held (usecs)
++ must be less than the total window size (enforced)
++window - total period of sampling, width being inside (usecs)
++
++By default we will set width to 500,000 and window to 1,000,000, meaning that
++we will sample every 1,000,000 usecs (1s) for 500,000 usecs (0.5s). If we
++observe any latencies that exceed the threshold (initially 100 usecs),
++then we write to a global sample ring buffer of 8K samples, which is
++consumed by reading from the "sample" (pipe) debugfs file interface.

++ Using the Linux Kernel Latency Histograms
++
++
++This document gives a short explanation how to enable, configure and use
++latency histograms. Latency histograms are primarily relevant in the
++context of real-time enabled kernels (CONFIG_PREEMPT/CONFIG_PREEMPT_RT)
++and are used in the quality management of the Linux real-time
++capabilities.
++
++
++* Purpose of latency histograms
++
++A latency histogram continuously accumulates the frequencies of latency
++data. There are two types of histograms
++- potential sources of latencies
++- effective latencies
++
++
++* Potential sources of latencies
++
++Potential sources of latencies are code segments where interrupts,
++preemption or both are disabled (aka critical sections). To create
++histograms of potential sources of latency, the kernel stores the time
++stamp at the start of a critical section, determines the time elapsed
++when the end of the section is reached, and increments the frequency
++counter of that latency value - irrespective of whether any concurrently
++running process is affected by latency or not.
++- Configuration items (in the Kernel hacking/Tracers submenu)
++ CONFIG_INTERRUPT_OFF_LATENCY
++ CONFIG_PREEMPT_OFF_LATENCY
++
++
++* Effective latencies
++
++Effective latencies are actually occuring during wakeup of a process. To
++determine effective latencies, the kernel stores the time stamp when a
++process is scheduled to be woken up, and determines the duration of the
++wakeup time shortly before control is passed over to this process. Note
++that the apparent latency in user space may be somewhat longer, since the
++process may be interrupted after control is passed over to it but before
++the execution in user space takes place. Simply measuring the interval
++between enqueuing and wakeup may also not appropriate in cases when a
++process is scheduled as a result of a timer expiration. The timer may have
++missed its deadline, e.g. due to disabled interrupts, but this latency
++would not be registered. Therefore, the offsets of missed timers are
++recorded in a separate histogram. If both wakeup latency and missed timer
++offsets are configured and enabled, a third histogram may be enabled that
++records the overall latency as a sum of the timer latency, if any, and the
++wakeup latency. This histogram is called "timerandwakeup".
++- Configuration items (in the Kernel hacking/Tracers submenu)
++ CONFIG_WAKEUP_LATENCY
++ CONFIG_MISSED_TIMER_OFSETS
++
++
++* Usage
++
++The interface to the administration of the latency histograms is located
++in the debugfs file system. To mount it, either enter
++
++mount -t sysfs nodev /sys
++mount -t debugfs nodev /sys/kernel/debug
++
++from shell command line level, or add
++
++nodev /sys sysfs defaults 0 0
++nodev /sys/kernel/debug debugfs defaults 0 0
++
++to the file /etc/fstab. All latency histogram related files are then
++available in the directory /sys/kernel/debug/tracing/latency_hist. A
++particular histogram type is enabled by writing non-zero to the related
++variable in the /sys/kernel/debug/tracing/latency_hist/enable directory.
++Select "preemptirqsoff" for the histograms of potential sources of
++latencies and "wakeup" for histograms of effective latencies etc. The
++histogram data - one per CPU - are available in the files
++
++/sys/kernel/debug/tracing/latency_hist/preemptoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/irqsoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/preemptirqsoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/wakeup/CPUx
++/sys/kernel/debug/tracing/latency_hist/wakeup/sharedprio/CPUx
++/sys/kernel/debug/tracing/latency_hist/missed_timer_offsets/CPUx
++/sys/kernel/debug/tracing/latency_hist/timerandwakeup/CPUx
++
++The histograms are reset by writing non-zero to the file "reset" in a
++particular latency directory. To reset all latency data, use
++
++#!/bin/sh
++
++TRACINGDIR=/sys/kernel/debug/tracing
++HISTDIR=$TRACINGDIR/latency_hist
++
++if test -d $HISTDIR
++then
++ cd $HISTDIR
++ for i in `find . | grep /reset$`
++ do
++ echo 1 >$i
++ done
++fi
++
++
++* Data format
++
++Latency data are stored with a resolution of one microsecond. The
++maximum latency is 10,240 microseconds. The data are only valid, if the
++overflow register is empty. Every output line contains the latency in
++microseconds in the first row and the number of samples in the second
++row. To display only lines with a positive latency count, use, for
++example,
++
++grep -v " 0$" /sys/kernel/debug/tracing/latency_hist/preemptoff/CPU0
++
++#Minimum latency: 0 microseconds.
++#Average latency: 0 microseconds.
++#Maximum latency: 25 microseconds.
++#Total samples: 3104770694
++#There are 0 samples greater or equal than 10240 microseconds
++#usecs samples
++ 0 2984486876
++ 1 49843506
++ 2 58219047
++ 3 5348126
++ 4 2187960
++ 5 3388262
++ 6 959289
++ 7 208294
++ 8 40420
++ 9 4485
++ 10 14918
++ 11 18340
++ 12 25052
++ 13 19455
++ 14 5602
++ 15 969
++ 16 47
++ 17 18
++ 18 14
++ 19 1
++ 20 3
++ 21 2
++ 22 5
++ 23 2
++ 25 1
++
++
++* Wakeup latency of a selected process
++
++To only collect wakeup latency data of a particular process, write the
++PID of the requested process to
++
++/sys/kernel/debug/tracing/latency_hist/wakeup/pid
++
++PIDs are not considered, if this variable is set to 0.
++
++
++* Details of the process with the highest wakeup latency so far
++
++Selected data of the process that suffered from the highest wakeup
++latency that occurred in a particular CPU are available in the file
++
++/sys/kernel/debug/tracing/latency_hist/wakeup/max_latency-CPUx.
++
++In addition, other relevant system data at the time when the
++latency occurred are given.
++
++The format of the data is (all in one line):
++<PID> <Priority> <Latency> (<Timeroffset>) <Command> \
++<- <PID> <Priority> <Command> <Timestamp>
++
++The value of <Timeroffset> is only relevant in the combined timer
++and wakeup latency recording. In the wakeup recording, it is
++always 0, in the missed_timer_offsets recording, it is the same
++as <Latency>.
++
++When retrospectively searching for the origin of a latency and
++tracing was not enabled, it may be helpful to know the name and
++some basic data of the task that (finally) was switching to the
++late real-tlme task. In addition to the victim's data, also the
++data of the possible culprit are therefore displayed after the
++"<-" symbol.
++
++Finally, the timestamp of the time when the latency occurred
++in <seconds>.<microseconds> after the most recent system boot
++is provided.
++
++These data are also reset when the wakeup histogram is reset.

-+Introduction:
-+-------------
-+
-+The module hwlat_detector is a special purpose kernel module that is used to
-+detect large system latencies induced by the behavior of certain underlying
-+hardware or firmware, independent of Linux itself. The code was developed
-+originally to detect SMIs (System Management Interrupts) on x86 systems,
-+however there is nothing x86 specific about this patchset. It was
-+originally written for use by the "RT" patch since the Real Time
-+kernel is highly latency sensitive.
-+
-+SMIs are usually not serviced by the Linux kernel, which typically does not
-+even know that they are occuring. SMIs are instead are set up by BIOS code
-+and are serviced by BIOS code, usually for "critical" events such as
-+management of thermal sensors and fans. Sometimes though, SMIs are used for
-+other tasks and those tasks can spend an inordinate amount of time in the
-+handler (sometimes measured in milliseconds). Obviously this is a problem if
-+you are trying to keep event service latencies down in the microsecond range.
-+
-+The hardware latency detector works by hogging all of the cpus for configurable
-+amounts of time (by calling stop_machine()), polling the CPU Time Stamp Counter
-+for some period, then looking for gaps in the TSC data. Any gap indicates a
-+time when the polling was interrupted and since the machine is stopped and
-+interrupts turned off the only thing that could do that would be an SMI.
-+
-+Note that the SMI detector should *NEVER* be used in a production environment.
-+It is intended to be run manually to determine if the hardware platform has a
-+problem with long system firmware service routines.
-+
-+Usage:
-+------
-+
-+Loading the module hwlat_detector passing the parameter "enabled=1" (or by
-+setting the "enable" entry in "hwlat_detector" debugfs toggled on) is the only
-+step required to start the hwlat_detector. It is possible to redefine the
-+threshold in microseconds (us) above which latency spikes will be taken
-+into account (parameter "threshold=").
-+
-+Example:
-+
-+ # modprobe hwlat_detector enabled=1 threshold=100
-+
-+After the module is loaded, it creates a directory named "hwlat_detector" under
-+the debugfs mountpoint, "/debug/hwlat_detector" for this text. It is necessary
-+to have debugfs mounted, which might be on /sys/debug on your system.
-+
-+The /debug/hwlat_detector interface contains the following files:
-+
-+count - number of latency spikes observed since last reset
-+enable - a global enable/disable toggle (0/1), resets count
-+max - maximum hardware latency actually observed (usecs)
-+sample - a pipe from which to read current raw sample data
-+ in the format <timestamp> <latency observed usecs>
-+ (can be opened O_NONBLOCK for a single sample)
-+threshold - minimum latency value to be considered (usecs)
-+width - time period to sample with CPUs held (usecs)
-+ must be less than the total window size (enforced)
-+window - total period of sampling, width being inside (usecs)
-+
-+By default we will set width to 500,000 and window to 1,000,000, meaning that
-+we will sample every 1,000,000 usecs (1s) for 500,000 usecs (0.5s). If we
-+observe any latencies that exceed the threshold (initially 100 usecs),
-+then we write to a global sample ring buffer of 8K samples, which is
-+consumed by reading from the "sample" (pipe) debugfs file interface.

-+ Using the Linux Kernel Latency Histograms
-+
-+
-+This document gives a short explanation how to enable, configure and use
-+latency histograms. Latency histograms are primarily relevant in the
-+context of real-time enabled kernels (CONFIG_PREEMPT/CONFIG_PREEMPT_RT)
-+and are used in the quality management of the Linux real-time
-+capabilities.
-+
-+
-+* Purpose of latency histograms
-+
-+A latency histogram continuously accumulates the frequencies of latency
-+data. There are two types of histograms
-+- potential sources of latencies
-+- effective latencies
-+
-+
-+* Potential sources of latencies
-+
-+Potential sources of latencies are code segments where interrupts,
-+preemption or both are disabled (aka critical sections). To create
-+histograms of potential sources of latency, the kernel stores the time
-+stamp at the start of a critical section, determines the time elapsed
-+when the end of the section is reached, and increments the frequency
-+counter of that latency value - irrespective of whether any concurrently
-+running process is affected by latency or not.
-+- Configuration items (in the Kernel hacking/Tracers submenu)
-+ CONFIG_INTERRUPT_OFF_LATENCY
-+ CONFIG_PREEMPT_OFF_LATENCY
-+
-+
-+* Effective latencies
-+
-+Effective latencies are actually occuring during wakeup of a process. To
-+determine effective latencies, the kernel stores the time stamp when a
-+process is scheduled to be woken up, and determines the duration of the
-+wakeup time shortly before control is passed over to this process. Note
-+that the apparent latency in user space may be somewhat longer, since the
-+process may be interrupted after control is passed over to it but before
-+the execution in user space takes place. Simply measuring the interval
-+between enqueuing and wakeup may also not appropriate in cases when a
-+process is scheduled as a result of a timer expiration. The timer may have
-+missed its deadline, e.g. due to disabled interrupts, but this latency
-+would not be registered. Therefore, the offsets of missed timers are
-+recorded in a separate histogram. If both wakeup latency and missed timer
-+offsets are configured and enabled, a third histogram may be enabled that
-+records the overall latency as a sum of the timer latency, if any, and the
-+wakeup latency. This histogram is called "timerandwakeup".
-+- Configuration items (in the Kernel hacking/Tracers submenu)
-+ CONFIG_WAKEUP_LATENCY
-+ CONFIG_MISSED_TIMER_OFSETS
-+
-+
-+* Usage
-+
-+The interface to the administration of the latency histograms is located
-+in the debugfs file system. To mount it, either enter
-+
-+mount -t sysfs nodev /sys
-+mount -t debugfs nodev /sys/kernel/debug
-+
-+from shell command line level, or add
-+
-+nodev /sys sysfs defaults 0 0
-+nodev /sys/kernel/debug debugfs defaults 0 0
-+
-+to the file /etc/fstab. All latency histogram related files are then
-+available in the directory /sys/kernel/debug/tracing/latency_hist. A
-+particular histogram type is enabled by writing non-zero to the related
-+variable in the /sys/kernel/debug/tracing/latency_hist/enable directory.
-+Select "preemptirqsoff" for the histograms of potential sources of
-+latencies and "wakeup" for histograms of effective latencies etc. The
-+histogram data - one per CPU - are available in the files
-+
-+/sys/kernel/debug/tracing/latency_hist/preemptoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/irqsoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/preemptirqsoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/wakeup/CPUx
-+/sys/kernel/debug/tracing/latency_hist/wakeup/sharedprio/CPUx
-+/sys/kernel/debug/tracing/latency_hist/missed_timer_offsets/CPUx
-+/sys/kernel/debug/tracing/latency_hist/timerandwakeup/CPUx
-+
-+The histograms are reset by writing non-zero to the file "reset" in a
-+particular latency directory. To reset all latency data, use
-+
-+#!/bin/sh
-+
-+TRACINGDIR=/sys/kernel/debug/tracing
-+HISTDIR=$TRACINGDIR/latency_hist
-+
-+if test -d $HISTDIR
-+then
-+ cd $HISTDIR
-+ for i in `find . | grep /reset$`
-+ do
-+ echo 1 >$i
-+ done
-+fi
-+
-+
-+* Data format
-+
-+Latency data are stored with a resolution of one microsecond. The
-+maximum latency is 10,240 microseconds. The data are only valid, if the
-+overflow register is empty. Every output line contains the latency in
-+microseconds in the first row and the number of samples in the second
-+row. To display only lines with a positive latency count, use, for
-+example,
-+
-+grep -v " 0$" /sys/kernel/debug/tracing/latency_hist/preemptoff/CPU0
-+
-+#Minimum latency: 0 microseconds.
-+#Average latency: 0 microseconds.
-+#Maximum latency: 25 microseconds.
-+#Total samples: 3104770694
-+#There are 0 samples greater or equal than 10240 microseconds
-+#usecs samples

-+
-+
-+* Wakeup latency of a selected process
-+
-+To only collect wakeup latency data of a particular process, write the
-+PID of the requested process to
-+
-+/sys/kernel/debug/tracing/latency_hist/wakeup/pid
-+
-+PIDs are not considered, if this variable is set to 0.
-+
-+
-+* Details of the process with the highest wakeup latency so far
-+
-+Selected data of the process that suffered from the highest wakeup
-+latency that occurred in a particular CPU are available in the file
-+
-+/sys/kernel/debug/tracing/latency_hist/wakeup/max_latency-CPUx.
-+
-+In addition, other relevant system data at the time when the
-+latency occurred are given.
-+
-+The format of the data is (all in one line):
-+<PID> <Priority> <Latency> (<Timeroffset>) <Command> \
-+<- <PID> <Priority> <Command> <Timestamp>
-+
-+The value of <Timeroffset> is only relevant in the combined timer
-+and wakeup latency recording. In the wakeup recording, it is
-+always 0, in the missed_timer_offsets recording, it is the same
-+as <Latency>.
-+
-+When retrospectively searching for the origin of a latency and
-+tracing was not enabled, it may be helpful to know the name and
-+some basic data of the task that (finally) was switching to the
-+late real-tlme task. In addition to the victim's data, also the
-+data of the possible culprit are therefore displayed after the
-+"<-" symbol.
-+
-+Finally, the timestamp of the time when the latency occurred
-+in <seconds>.<microseconds> after the most recent system boot
-+is provided.
-+
-+These data are also reset when the wakeup histogram is reset.

++ Using the Linux Kernel Latency Histograms
++
++
++This document gives a short explanation how to enable, configure and use
++latency histograms. Latency histograms are primarily relevant in the
++context of real-time enabled kernels (CONFIG_PREEMPT/CONFIG_PREEMPT_RT)
++and are used in the quality management of the Linux real-time
++capabilities.
++
++
++* Purpose of latency histograms
++
++A latency histogram continuously accumulates the frequencies of latency
++data. There are two types of histograms
++- potential sources of latencies
++- effective latencies
++
++
++* Potential sources of latencies
++
++Potential sources of latencies are code segments where interrupts,
++preemption or both are disabled (aka critical sections). To create
++histograms of potential sources of latency, the kernel stores the time
++stamp at the start of a critical section, determines the time elapsed
++when the end of the section is reached, and increments the frequency
++counter of that latency value - irrespective of whether any concurrently
++running process is affected by latency or not.
++- Configuration items (in the Kernel hacking/Tracers submenu)
++ CONFIG_INTERRUPT_OFF_LATENCY
++ CONFIG_PREEMPT_OFF_LATENCY
++
++
++* Effective latencies
++
++Effective latencies are actually occuring during wakeup of a process. To
++determine effective latencies, the kernel stores the time stamp when a
++process is scheduled to be woken up, and determines the duration of the
++wakeup time shortly before control is passed over to this process. Note
++that the apparent latency in user space may be somewhat longer, since the
++process may be interrupted after control is passed over to it but before
++the execution in user space takes place. Simply measuring the interval
++between enqueuing and wakeup may also not appropriate in cases when a
++process is scheduled as a result of a timer expiration. The timer may have
++missed its deadline, e.g. due to disabled interrupts, but this latency
++would not be registered. Therefore, the offsets of missed timers are
++recorded in a separate histogram. If both wakeup latency and missed timer
++offsets are configured and enabled, a third histogram may be enabled that
++records the overall latency as a sum of the timer latency, if any, and the
++wakeup latency. This histogram is called "timerandwakeup".
++- Configuration items (in the Kernel hacking/Tracers submenu)
++ CONFIG_WAKEUP_LATENCY
++ CONFIG_MISSED_TIMER_OFSETS
++
++
++* Usage
++
++The interface to the administration of the latency histograms is located
++in the debugfs file system. To mount it, either enter
++
++mount -t sysfs nodev /sys
++mount -t debugfs nodev /sys/kernel/debug
++
++from shell command line level, or add
++
++nodev /sys sysfs defaults 0 0
++nodev /sys/kernel/debug debugfs defaults 0 0
++
++to the file /etc/fstab. All latency histogram related files are then
++available in the directory /sys/kernel/debug/tracing/latency_hist. A
++particular histogram type is enabled by writing non-zero to the related
++variable in the /sys/kernel/debug/tracing/latency_hist/enable directory.
++Select "preemptirqsoff" for the histograms of potential sources of
++latencies and "wakeup" for histograms of effective latencies etc. The
++histogram data - one per CPU - are available in the files
++
++/sys/kernel/debug/tracing/latency_hist/preemptoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/irqsoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/preemptirqsoff/CPUx
++/sys/kernel/debug/tracing/latency_hist/wakeup/CPUx
++/sys/kernel/debug/tracing/latency_hist/wakeup/sharedprio/CPUx
++/sys/kernel/debug/tracing/latency_hist/missed_timer_offsets/CPUx
++/sys/kernel/debug/tracing/latency_hist/timerandwakeup/CPUx
++
++The histograms are reset by writing non-zero to the file "reset" in a
++particular latency directory. To reset all latency data, use
++
++#!/bin/sh
++
++TRACINGDIR=/sys/kernel/debug/tracing
++HISTDIR=$TRACINGDIR/latency_hist
++
++if test -d $HISTDIR
++then
++ cd $HISTDIR
++ for i in `find . | grep /reset$`
++ do
++ echo 1 >$i
++ done
++fi
++
++
++* Data format
++
++Latency data are stored with a resolution of one microsecond. The
++maximum latency is 10,240 microseconds. The data are only valid, if the
++overflow register is empty. Every output line contains the latency in
++microseconds in the first row and the number of samples in the second
++row. To display only lines with a positive latency count, use, for
++example,
++
++grep -v " 0$" /sys/kernel/debug/tracing/latency_hist/preemptoff/CPU0
++
++#Minimum latency: 0 microseconds.
++#Average latency: 0 microseconds.
++#Maximum latency: 25 microseconds.
++#Total samples: 3104770694
++#There are 0 samples greater or equal than 10240 microseconds
++#usecs samples
++ 0 2984486876
++ 1 49843506
++ 2 58219047
++ 3 5348126
++ 4 2187960
++ 5 3388262
++ 6 959289
++ 7 208294
++ 8 40420
++ 9 4485
++ 10 14918
++ 11 18340
++ 12 25052
++ 13 19455
++ 14 5602
++ 15 969
++ 16 47
++ 17 18
++ 18 14
++ 19 1
++ 20 3
++ 21 2
++ 22 5
++ 23 2
++ 25 1
++
++
++* Wakeup latency of a selected process
++
++To only collect wakeup latency data of a particular process, write the
++PID of the requested process to
++
++/sys/kernel/debug/tracing/latency_hist/wakeup/pid
++
++PIDs are not considered, if this variable is set to 0.
++
++
++* Details of the process with the highest wakeup latency so far
++
++Selected data of the process that suffered from the highest wakeup
++latency that occurred in a particular CPU are available in the file
++
++/sys/kernel/debug/tracing/latency_hist/wakeup/max_latency-CPUx.
++
++In addition, other relevant system data at the time when the
++latency occurred are given.
++
++The format of the data is (all in one line):
++<PID> <Priority> <Latency> (<Timeroffset>) <Command> \
++<- <PID> <Priority> <Command> <Timestamp>
++
++The value of <Timeroffset> is only relevant in the combined timer
++and wakeup latency recording. In the wakeup recording, it is
++always 0, in the missed_timer_offsets recording, it is the same
++as <Latency>.
++
++When retrospectively searching for the origin of a latency and
++tracing was not enabled, it may be helpful to know the name and
++some basic data of the task that (finally) was switching to the
++late real-tlme task. In addition to the victim's data, also the
++data of the possible culprit are therefore displayed after the
++"<-" symbol.
++
++Finally, the timestamp of the time when the latency occurred
++in <seconds>.<microseconds> after the most recent system boot
++is provided.
++
++These data are also reset when the wakeup histogram is reset.

-+ Using the Linux Kernel Latency Histograms
-+
-+
-+This document gives a short explanation how to enable, configure and use
-+latency histograms. Latency histograms are primarily relevant in the
-+context of real-time enabled kernels (CONFIG_PREEMPT/CONFIG_PREEMPT_RT)
-+and are used in the quality management of the Linux real-time
-+capabilities.
-+
-+
-+* Purpose of latency histograms
-+
-+A latency histogram continuously accumulates the frequencies of latency
-+data. There are two types of histograms
-+- potential sources of latencies
-+- effective latencies
-+
-+
-+* Potential sources of latencies
-+
-+Potential sources of latencies are code segments where interrupts,
-+preemption or both are disabled (aka critical sections). To create
-+histograms of potential sources of latency, the kernel stores the time
-+stamp at the start of a critical section, determines the time elapsed
-+when the end of the section is reached, and increments the frequency
-+counter of that latency value - irrespective of whether any concurrently
-+running process is affected by latency or not.
-+- Configuration items (in the Kernel hacking/Tracers submenu)
-+ CONFIG_INTERRUPT_OFF_LATENCY
-+ CONFIG_PREEMPT_OFF_LATENCY
-+
-+
-+* Effective latencies
-+
-+Effective latencies are actually occuring during wakeup of a process. To
-+determine effective latencies, the kernel stores the time stamp when a
-+process is scheduled to be woken up, and determines the duration of the
-+wakeup time shortly before control is passed over to this process. Note
-+that the apparent latency in user space may be somewhat longer, since the
-+process may be interrupted after control is passed over to it but before
-+the execution in user space takes place. Simply measuring the interval
-+between enqueuing and wakeup may also not appropriate in cases when a
-+process is scheduled as a result of a timer expiration. The timer may have
-+missed its deadline, e.g. due to disabled interrupts, but this latency
-+would not be registered. Therefore, the offsets of missed timers are
-+recorded in a separate histogram. If both wakeup latency and missed timer
-+offsets are configured and enabled, a third histogram may be enabled that
-+records the overall latency as a sum of the timer latency, if any, and the
-+wakeup latency. This histogram is called "timerandwakeup".
-+- Configuration items (in the Kernel hacking/Tracers submenu)
-+ CONFIG_WAKEUP_LATENCY
-+ CONFIG_MISSED_TIMER_OFSETS
-+
-+
-+* Usage
-+
-+The interface to the administration of the latency histograms is located
-+in the debugfs file system. To mount it, either enter
-+
-+mount -t sysfs nodev /sys
-+mount -t debugfs nodev /sys/kernel/debug
-+
-+from shell command line level, or add
-+
-+nodev /sys sysfs defaults 0 0
-+nodev /sys/kernel/debug debugfs defaults 0 0
-+
-+to the file /etc/fstab. All latency histogram related files are then
-+available in the directory /sys/kernel/debug/tracing/latency_hist. A
-+particular histogram type is enabled by writing non-zero to the related
-+variable in the /sys/kernel/debug/tracing/latency_hist/enable directory.
-+Select "preemptirqsoff" for the histograms of potential sources of
-+latencies and "wakeup" for histograms of effective latencies etc. The
-+histogram data - one per CPU - are available in the files
-+
-+/sys/kernel/debug/tracing/latency_hist/preemptoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/irqsoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/preemptirqsoff/CPUx
-+/sys/kernel/debug/tracing/latency_hist/wakeup/CPUx
-+/sys/kernel/debug/tracing/latency_hist/wakeup/sharedprio/CPUx
-+/sys/kernel/debug/tracing/latency_hist/missed_timer_offsets/CPUx
-+/sys/kernel/debug/tracing/latency_hist/timerandwakeup/CPUx
-+
-+The histograms are reset by writing non-zero to the file "reset" in a
-+particular latency directory. To reset all latency data, use
-+
-+#!/bin/sh
-+
-+TRACINGDIR=/sys/kernel/debug/tracing
-+HISTDIR=$TRACINGDIR/latency_hist
-+
-+if test -d $HISTDIR
-+then
-+ cd $HISTDIR
-+ for i in `find . | grep /reset$`
-+ do
-+ echo 1 >$i
-+ done
-+fi
-+
-+
-+* Data format
-+
-+Latency data are stored with a resolution of one microsecond. The
-+maximum latency is 10,240 microseconds. The data are only valid, if the
-+overflow register is empty. Every output line contains the latency in
-+microseconds in the first row and the number of samples in the second
-+row. To display only lines with a positive latency count, use, for
-+example,
-+
-+grep -v " 0$" /sys/kernel/debug/tracing/latency_hist/preemptoff/CPU0
-+
-+#Minimum latency: 0 microseconds.
-+#Average latency: 0 microseconds.
-+#Maximum latency: 25 microseconds.
-+#Total samples: 3104770694
-+#There are 0 samples greater or equal than 10240 microseconds
-+#usecs samples

-+* Wakeup latency of a selected process
-+
-+To only collect wakeup latency data of a particular process, write the
-+PID of the requested process to
-+
-+/sys/kernel/debug/tracing/latency_hist/wakeup/pid
-+
-+PIDs are not considered, if this variable is set to 0.
-+
-+
-+* Details of the process with the highest wakeup latency so far
-+
-+Selected data of the process that suffered from the highest wakeup
-+latency that occurred in a particular CPU are available in the file
-+
-+/sys/kernel/debug/tracing/latency_hist/wakeup/max_latency-CPUx.
-+
-+In addition, other relevant system data at the time when the
-+latency occurred are given.
-+
-+The format of the data is (all in one line):
-+<PID> <Priority> <Latency> (<Timeroffset>) <Command> \
-+<- <PID> <Priority> <Command> <Timestamp>
-+
-+The value of <Timeroffset> is only relevant in the combined timer
-+and wakeup latency recording. In the wakeup recording, it is
-+always 0, in the missed_timer_offsets recording, it is the same
-+as <Latency>.
-+
-+When retrospectively searching for the origin of a latency and
-+tracing was not enabled, it may be helpful to know the name and
-+some basic data of the task that (finally) was switching to the
-+late real-tlme task. In addition to the victim's data, also the
-+data of the possible culprit are therefore displayed after the
-+"<-" symbol.
-+
-+Finally, the timestamp of the time when the latency occurred
-+in <seconds>.<microseconds> after the most recent system boot
-+is provided.
-+
-+These data are also reset when the wakeup histogram is reset.
