Date: Tue,  3 Jan 2023 16:20:34 +0000	[thread overview]
Message-ID: <20230103162042.423694-1-james.clark@arm.com> (raw)

Changes since v2:

  * Remove const to non-const change and copy strings where needed
    instead.
  * Use sizeof() instead of PATH_MAX
  * Append "will not be set accurately." to new error message
  * Remove unneeded stat() call
  * Rebase on perf/core

==========================

Changes since v1:

  * Add 3 refactor commits for sysfs reading around pmu.c as suggested
    by Arnaldo here [1]
  * The dependency on [2] has now reached mainline so is no longer
    blocking
  * Rebase on perf/core

  perf pmu: Add function to check if a pmu file exists
  perf cs_etm: Keep separate symbols for ETMv4 and ETE parameters
  perf cs_etm: Record ts_source in AUXTRACE_INFO for ETMv4 and ETE
  perf cs_etm: Set the time field in the synthetic samples

James Clark (3):
  perf: Remove duplication around EVENT_SOURCE_DEVICE_PATH
  perf: Use perf_pmu__open_file() and perf_pmu__scan_file()
  perf: Remove remaining duplication of bus/event_source/devices/...
