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 <[email protected]> Signed-off-by: Peter Zijlstra (Intel) <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Cc: Thomas Gleixner <[email protected]> Cc: Vince Weaver <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]>
