Subject: [Patch v2 00/24] Arch-PEBS and PMU supports for Clearwater Forest and Panther Lake
This v2 patch series is based on latest perf/core tree "1623ced247f7
(x86/events/amd/iommu: Increase IOMMU_NAME_SIZE)" + extra first two
patches of patch set "Cleanup for Intel PMU initialization"[1].
Changes:
v1 -> v2:
* Add Panther Lake PMU support (patch 02/24)
* Add PEBS static calls to avoid introducing too much
x86_pmu.arch_pebs checks (patch 07~08/24)
* Optimize PEBS constraints base on Kan's dynamic constranit patch
(patch 13/24)
* Split perf tools patch of supporting more vector registers to
several small patches (patch 20~22/24)
Tests:
* Run below tests on Clearwater Forest and no issue is found. Please
notice nmi_watchdog is disabled when running the tests.
a. Basic perf counting case.
perf stat -e '{branches,branches,branches,branches,branches,branches,branches,branches,cycles,instructions,ref-cycles,topdown-bad-spec,topdown-fe-bound,topdown-retiring}' sleep 1
b. Basic PMI based perf sampling case.
perf record -e '{branches,branches,branches,branches,branches,branches,branches,branches,cycles,instructions,ref-cycles,topdown-bad-spec,topdown-fe-bound,topdown-retiring}' sleep 1
c. Basic PEBS based perf sampling case.
perf record -e '{branches,branches,branches,branches,branches,branches,branches,branches,cycles,instructions,ref-cycles,topdown-bad-spec,topdown-fe-bound,topdown-retiring}:p' sleep 1
d. PEBS sampling case with basic, GPRs, vector-registers and LBR groups
perf record -e branches:p -Iax,bx,ip,ssp,xmm0,ymmh0 -b -c 10000 sleep 1
e. PEBS sampling case with auxiliary (memory info) group
perf mem record sleep 1
f. PEBS sampling case with counter group
perf record -e '{branches:p,branches,cycles}:S' -c 10000 sleep 1
g. Perf stat and record test
perf test 95; perf test 119
h. perf-fuzzer test
* Run similar tests on Panther Lake P-cores and E-cores and no issue
is found. CPU 0 is P-core and CPU 9 is E-core. nmi_watchdog is
disabled as well.
