[PATCH v3 0/7] perf cs_etm: Basic support for virtual/kernel timestamps

From: James Clark
Date: Tue Jan 03 2023 - 11:22:46 EST


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
