perf/core improvements and fixes:
User visible:
* Add a visual cue for toggle zeroing of samples in 'perf top' (Taeung Song)
* Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
Infrastructure:
* Add option to copy events when queuing for sorting across cpu buffers
and enable it for 'perf kvm stat live', to avoid having events left
in the queue pointing to the ring buffer be rewritten in high volume
sessions. (Alexander Yarygin, improving work done by David Ahern):
* Document sysfs events/ interfaces (Cody P Schafer)
* Add support to new style format of kernel PMU event. (Kan Liang)
* Fix typos in perf/Documentation (Masanari Iida)
* Improve callchains when using libunwind (Namhyung Kim)

Description: Per-pmu performance monitoring events specific to the running system
|
||||
|
||||
Description: POWER-systems specific performance monitoring events
|
||||
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.
|
||||
|
||||
A collection of performance monitoring events that may be
|
||||
supported by the POWER CPU. These events can be monitored
|
||||
using the 'perf(1)' tool.
|
||||
File contents:
|
||||
|
||||
These events may not be supported by other CPUs.
|
||||
<term>[=<value>][,<term>[=<value>]]...
|
||||
|
||||
The contents of each file would look like:
|
||||
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>.
|
||||
|
||||
event=0xNNNN
|
||||
Examples (each of these lines would be in a seperate 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".
|
||||
event=0x2abc
|
||||
event=0x423,inv,cmask=0x3
|
||||
domain=0x1,offset=0x8,starting_index=0xffff
|
||||
|
||||
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.
|
||||
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
|
||||
|
||||
A string specifying the English plural numerical unit that <event>
|
||||
(once multiplied by <event>.scale) represents.

||||
Example:

Description: Perf event scaling factors
|
||||
|
||||
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.
