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.

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. -diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt -index 0e4102ae1a61..26b5f39d57a8 100644 ---- a/Documentation/kernel-parameters.txt -+++ b/Documentation/kernel-parameters.txt -@@ -1629,6 +1629,15 @@ bytes respectively.

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.

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. +diff -Nur linux-4.4.28.orig/Documentation/kernel-parameters.txt linux-4.4.28/Documentation/kernel-parameters.txt +--- linux-4.4.28.orig/Documentation/kernel-parameters.txt 2016-10-28 09:53:25.000000000 +0200 ++++ linux-4.4.28/Documentation/kernel-parameters.txt 2016-11-01 21:26:56.640204584 +0100 +@@ -1636,6 +1636,15 @@ + ip= [IP_PNP] + See Documentation/filesystems/nfs/nfsroot.txt. + ++ irqaffinity= [SMP] Set the default irq affinity mask ++ Format: ++ <cpu number>,...,<cpu number> ++ or ++ <cpu number>-<cpu number> ++ (must be a positive range in ascending order) ++ or a mixture ++ <cpu number>,...,<cpu number>-<cpu number> ++ + irqfixup [HW] + When an interrupt is not handled search all handlers + for it.

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.
