hi,
here's the change to make following syntax available:
perf stat -e cpu/event=instructions/u ls
perf stat -e cpu/cycles/u ls
this is identical to:
perf stat -e instructions:u ls
perf stat -e cycles:u ls
v4 changes:
- kernel change is now structured differently allowing
to pick up cpu differences
- added support for intel/p6/amd PMUs - intel and amd tested,
did not get p6 server, but should be ok.. feel free to omit
Attached patches:
1/8 perf x86: Making hardware events translations available in sysfs
2/8 perf x86: Filter out undefined events from sysfs events attribute
3/8 perf x86: Adding hardware events translations for intel cpus
4/8 perf x86: Adding hardware events translations for amd cpus
5/8 perf x86: Adding hardware events translations for p6 cpus
6/8 perf tools: Fix pmu object alias initialization
7/8 perf tools: Add support to specify hw event as pmu event term
8/8 perf test: Add automated tests for pmu sysfs translated events
