============
|
||
|
||
NAME
|
||
----
|
||
perf-list - List all symbolic event types
|
||
|
||
SYNOPSIS
|
||
--------
|
||
[verse]
|
||
'perf list'
|
||
|
||
DESCRIPTION
|
||
-----------
|
||
This command displays the symbolic event types which can be selected in the
|
||
various perf commands with the -e option.
|
||
|
||
RAW HARDWARE EVENT DESCRIPTOR
|
||
-----------------------------
|
||
Even when an event is not available in a symbolic form within perf right now,
|
||
it can be encoded in a per processor specific way.
|
||
|
||
For instance For x86 CPUs NNN represents the raw register encoding with the
|
||
layout of IA32_PERFEVTSELx MSRs (see [Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 3B: System Programming Guide] Figure 30-1 Layout
|
||
of IA32_PERFEVTSELx MSRs) or AMD's PerfEvtSeln (see [AMD64 Architecture Programmer’s Manual Volume 2: System Programming], Page 344,
|
||
Figure 13-7 Performance Event-Select Register (PerfEvtSeln)).
|
||
|
||
Example:
|
||
|
||
If the Intel docs for a QM720 Core i7 describe an event as:
|
||
|
||
Event Umask Event Mask
|
||
Num. Value Mnemonic Description Comment
|
||
|
||
A8H 01H LSD.UOPS Counts the number of micro-ops Use cmask=1 and
|
||
delivered by loop stream detector invert to count
|
||
cycles
|
||
|
||
raw encoding of 0x1A8 can be used:
|
||
|
||
perf stat -e r1a8 -a sleep 1
|
||
perf record -e r1a8 ...
|
||
|
||
You should refer to the processor specific documentation for getting these
|
||
details. Some of them are referenced in the SEE ALSO section below.
