perf/x86/rapl: Enable Apollo Lake RAPL support
This patch enables RAPL counters (energy consumption counters) support for Intel Apollo Lake (Goldmont) processors (Model 92): RAPL of Goldmont, unlikes ESU increment of Silvermont/Airmont, it likes the Haswell microarchitecture in 1/2^ESU joules and supports power domains in PP0/PP1/PKG/RAM. ESU and power domains refer to Intel Software Developers' Manual, Vol. 3C, Order No. 325384, Table 35-12. Usage example: $ perf list $ perf stat -a -e power/energy-cores/,power/energy-pkg/ sleep 10 Signed-off-by: Harry Pan <harry.pan@intel.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Vince Weaver <vincent.weaver@maine.edu> Cc: bp@alien8.de Cc: gs0622@gmail.com Cc: hpa@zytor.com Cc: srinivas.pandruvada@linux.intel.com Link: http://lkml.kernel.org/r/1473325738-730-1-git-send-email-harry.pan@intel.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
