From: Alexander Shishkin Date: Fri, 27 Jan 2017 15:16:43 +0000 (+0200) Subject: perf/x86/intel/pt: Add format strings for PTWRITE and power event tracing X-Git-Tag: C0P2-H0.0--20200415~9213 X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=89e8bd3add69debe228842e73b1df9925b44eb6e;p=linux.git perf/x86/intel/pt: Add format strings for PTWRITE and power event tracing commit 5443624bedd0d23e112d5f2a919435182875bce9 upstream. Commit: 8ee83b2ab3 ("perf/x86/intel/pt: Add support for PTWRITE and power event tracing") forgot to add format strings to the PT driver. So one could enable these features by setting corresponding bits in the event config, but not by their mnemonic names. This patch adds the format strings.
