6 perf-list - List all symbolic event types
15 This command displays the symbolic event types which can be selected in the
16 various perf commands with the -e option.
18 RAW HARDWARE EVENT DESCRIPTOR
19 -----------------------------
20 Even when an event is not available in a symbolic form within perf right now,
21 it can be encoded in a per processor specific way.
23 For instance For x86 CPUs NNN represents the raw register encoding with the
24 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
25 of IA32_PERFEVTSELx MSRs) or AMD's PerfEvtSeln (see [AMD64 Architecture Programmer’s Manual Volume 2: System Programming], Page 344,
26 Figure 13-7 Performance Event-Select Register (PerfEvtSeln)).
30 If the Intel docs for a QM720 Core i7 describe an event as:
32 Event Umask Event Mask
33 Num. Value Mnemonic Description Comment
35 A8H 01H LSD.UOPS Counts the number of micro-ops Use cmask=1 and
36 delivered by loop stream detector invert to count
39 raw encoding of 0x1A8 can be used:
41 perf stat -e r1a8 -a sleep 1
42 perf record -e r1a8 ...
44 You should refer to the processor specific documentation for getting these
45 details. Some of them are referenced in the SEE ALSO section below.
