Subject: [PATCH 0/6] perf header: Save and reuse feature information in header (v5)
Hi,
Currently the perf header information is used only at initial setup
time and discarded. If it's saved we could reuse the information for
various purpose - for instance, perf kvm stat needs to know cpuid so
it had to invent an accessor.
Thanks,
Namhyung
v4 -> v5:
* Use saved cpuid info for perf kvm (David)
v3 -> v4:
* rename perf_header_info to perf_session_env (Arnaldo)
v2 -> v3:
* patch 1-3 in v2 merged into tip
* rebased on current acme/perf/core
v1 -> v2:
* not touch EVENT_DESC feature handling
* split out struct perf_header_info
* simplify multi-string handling
* add some cleanup patches
Namhyung Kim (6):
perf header: Add struct perf_session_env
perf header: Add ->process callbacks to most of features
perf header: Use pre-processed session env when printing
perf header: Remove unused @feat arg from ->process callback
perf kvm: Use perf_session_env for reading cpuid
perf header: Remove perf_header__read_feature
