-+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.

-+ * hwlat_detector.c - A simple Hardware Latency detector.
-+ *
-+ * Use this module to detect large system latencies induced by the behavior of
-+ * certain underlying system hardware or firmware, independent of Linux itself.
-+ * The code was developed originally to detect the presence of SMIs on Intel
-+ * and AMD systems, although there is no dependency upon x86 herein.
-+ *
-+ * The classical example usage of this module is in detecting the presence of
-+ * SMIs or System Management Interrupts on Intel and AMD systems. An SMI is a
-+ * somewhat special form of hardware interrupt spawned from earlier CPU debug
-+ * modes in which the (BIOS/EFI/etc.) firmware arranges for the South Bridge
-+ * LPC (or other device) to generate a special interrupt under certain
-+ * circumstances, for example, upon expiration of a special SMI timer device,
-+ * due to certain external thermal readings, on certain I/O address accesses,
-+ * and other situations. An SMI hits a special CPU pin, triggers a special
-+ * SMI mode (complete with special memory map), and the OS is unaware.
-+ *
-+ * Although certain hardware-inducing latencies are necessary (for example,
-+ * a modern system often requires an SMI handler for correct thermal control
-+ * and remote management) they can wreak havoc upon any OS-level performance
-+ * guarantees toward low-latency, especially when the OS is not even made
-+ * aware of the presence of these interrupts. For this reason, we need a
-+ * somewhat brute force mechanism to detect these interrupts. In this case,
-+ * we do it by hogging all of the CPU(s) for configurable timer intervals,
-+ * sampling the built-in CPU timer, looking for discontiguous readings.
-+ *
-+ * WARNING: This implementation necessarily introduces latencies. Therefore,
-+ * you should NEVER use this module in a production environment
-+ * requiring any kind of low-latency performance guarantee(s).

-+ A simple hardware latency detector. Use this module to detect
-+ large latencies introduced by the behavior of the underlying
-+ system firmware external to Linux. We do this using periodic
-+ use of stop_machine to grab all available CPUs and measure
-+ for unexplainable gaps in the CPU timestamp counter(s). By
-+ default, the module is not enabled until the "enable" file
-+ within the "hwlat_detector" debugfs directory is toggled.
-+
-+ This module is often used to detect SMI (System Management
-+ Interrupts) on x86 systems, though is not x86 specific. To
-+ this end, we default to using a sample window of 1 second,
-+ during which we will sample for 0.5 seconds. If an SMI or
-+ similar event occurs during that time, it is recorded
-+ into an 8K samples global ring buffer until retreived.
-+
-+ WARNING: This software should never be enabled (it can be built
-+ but should not be turned on after it is loaded) in a production
-+ environment where high latencies are a concern since the
-+ sampling mechanism actually introduces latencies for
-+ regular tasks while the CPU(s) are being held.
