perf-list(1)
============

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.
