Subject: [PATCH V3 00/23] perf: Add Icelake support
From: Kan Liang <kan.liang@...ux.intel.com>
The patch series intends to add Icelake support for Linux perf.
PATCH 1-18: Kernel patches to support Icelake.
- 1-5: Support adaptive PEBS feature
- 6-7: Enable core support with some new features, e.g. 8 generic
counters, new event constraints, a new fixed counter.
- 8-11: Enable cstate, rapl, msr and uncore support on Icelake
- 12-18: Support hardware Metrics counters and SLOT fixed counter for
Topdown events.
- 19: Support CPUID 10.ECX to disable fixed counters
PATCH 20-23: Perf tool patches to support XMM, Topdown and event list.
Changes since V2:
- Make the setup_pebs_sample_data() a function pointer argument
- Use cpuc->pebs_record_size unconditionally
- Add comments for EVENT_CONSTRAINT_RANGE
- Correct the Author of "perf/x86: Support constraint ranges"
Changes since V1:
- Avoid the interface changes for perf_reg_value() and
perf_output_sample_regs().
- Remove the extra_regs in struct perf_sample_data.
- Add struct x86_perf_regs
- Add has_xmm_regs to indicate the specific platform which support XMM
registers collection.
- Add check in x86_pmu_hw_config() to reject invalid config of regs_user
and regs_intr.
- Rename intel_hsw_weight and intel_hsw_transaction
- Add missed inline for intel_get_tsx_transaction()
- Add new patch to extract code of event update in short period
- Code rebase on top of c634dc6bdede
- Rename @d to pebs_data_cfg
- Make pebs_update_adaptive_cfg readable
- Clear pebs_data_cfg and pebs_record_size for first PEBS in add
- Don't clear ICL_EVENTSEL_ADAPTIVE. Rely on MSR_PEBS_CFG settings
- Change PEBS record parsing order (bug fix)
- Support struct x86_perf_regs
- make get_pebs_status generic
- specific intel_pmu_drain_pebs_icl()
- Use cpuc->pebs_record_size to replace format_size
- Use 'size' to replace 'range_end' for constraint ranges
- Add x86_pmu.has_xmm_regs = true;
- Add more explanation in change log of REMOVE transaction
- Make perf_regs.h consistent between kernel and user space
