Subject: perf: Add basic Skylake PMU support v2
Date: Sun, 10 May 2015 12:22:38 -0700 [thread overview]
Message-ID: <1431285767-27027-1-git-send-email-andi@firstfloor.org> (raw)
This patchkit adds support for the Intel Skylake core PMU to perf, documented in the
recently released SDM 054[1] Vol3, 17.9 and 18.12.
The main user visible feature is timed branch records, which allows to get cycle counts
for individual basic blocks, and a time stamp for PEBS records which improves
multi-record PEBS. The LBRs (branch records) also have been extended to 32, which allows
more accurate branch sampling and deeper call stacks.
v2:
Fix time stamp handling with non default clock.
Fix LBR freezing.
Some minor cleanups.
Moved user tools support for cycles into separate patchkit.
