Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
- The notify_free file is read-only and specifies the number of
- swap slot free notifications received by this device. These
- notifications are sent to a swap block device when a swap slot
- is freed. This statistic is applicable only when this disk is
- being used as a swap disk.
+ The notify_free file is read-only. Depending on device usage
+ scenario it may account a) the number of pages freed because
+ of swap slot free notifications or b) the number of pages freed
+ because of REQ_DISCARD requests sent by bio. The former ones
+ are sent to a swap block device when a swap slot is freed, which
+ implies that this disk is being used as a swap disk. The latter
+ ones are sent by filesystem mounted with discard option,
+ whenever some data blocks are getting discarded.

+Description: Per-pmu performance monitoring events specific to the running system
-Date: 2013/01/08
+ Each file (except for some of those with a '.' in them, '.unit'
+ and '.scale') in the 'events' directory describes a single
+ performance monitoring event supported by the <pmu>. The name
+ of the file is the name of the event.
+
+ File contents:
+
+ <term>[=<value>][,<term>[=<value>]]...
+
+ Where <term> is one of the terms listed under
+ /sys/bus/event_source/devices/<pmu>/format/ and <value> is
+ a number is base-16 format with a '0x' prefix (lowercase only).
+ If a <term> is specified alone (without an assigned value), it
+ is implied that 0x1 is assigned to that <term>.
+ Examples (each of these lines would be in a seperate file):
+
+ event=0x2abc
+ event=0x423,inv,cmask=0x3
+ domain=0x1,offset=0x8,starting_index=0xffff
+
+ Each of the assignments indicates a value to be assigned to a
+ particular set of bits (as defined by the format file
+ corresponding to the <term>) in the perf_event structure passed
+ to the perf_open syscall.

+Description: Perf event units
-Description: POWER-systems specific performance monitoring events
+ A string specifying the English plural numerical unit that <event>
+ (once multiplied by <event>.scale) represents.
- A collection of performance monitoring events that may be
- supported by the POWER CPU. These events can be monitored
- using the 'perf(1)' tool.
+ Example:
- These events may not be supported by other CPUs.

+Date: 2014/02/24

+Description: Perf event scaling factors
- event=0xNNNN
+ A string representing a floating point value expressed in
+ scientific notation to be multiplied by the event count
+ recieved from the kernel to match the unit specified in the
+ <event>.unit file.
- where 'N' is a hex digit and the number '0xNNNN' shows the
- "raw code" for the perf event identified by the file's
- "basename".
+ Example:
+
+ 2.3283064365386962890625e-10
- Further, multiple terms like 'event=0xNNNN' can be specified
- and separated with comma. All available terms are defined in
- the /sys/bus/event_source/devices/<dev>/format file.
+ This is provided to avoid performing floating point arithmetic
+ in the kernel.
