This patch series adds support for AMD Fam17h RAPL counters. As per AMD PPR, Fam17h support Package RAPL counters to monitor power usage. The RAPL counter operates as with Intel RAPL. As such, it is beneficial to share the code.
The series first moves the rapl.c file to common perf_events x86 and then adds the support. >From the user's point of view, the interface is identical with /sys/devices/power. The energy-pkg event is the only one supported. $ perf stat -a --per-socket -I 1000 -e power/energy-pkg/ Signed-off-by: Stephane Eranian <eran...@google.com> Stephane Eranian (3): perf/x86/rapl: move RAPL support to common x86 code perf/x86/rapl: refactor code for Intel/AMD sharing perf/x86/rapl: add AMD Fam17h RAPL support arch/x86/events/Kconfig | 8 ++--- arch/x86/events/Makefile | 1 + arch/x86/events/intel/Makefile | 2 -- arch/x86/events/probe.c | 4 +++ arch/x86/events/{intel => }/rapl.c | 55 +++++++++++++++++++++++++----- arch/x86/include/asm/msr-index.h | 3 ++ 6 files changed, 58 insertions(+), 15 deletions(-) rename arch/x86/events/{intel => }/rapl.c (92%) -- 2.26.2.761.g0e0b3e54be-goog
