According to the dmesg below, I don't think it is the psys domain that is missing. The difference is that we get 2 package domains in some cases, while we get 1 package domain in other cases. One possibility is that you're switching between different kernels, and one kernel is built with CONFIG_PROC_THERMAL_MMIO_RAPL set, and one is not. can you make a double check? if that is not the problem, please attach the output of "grep . /sys/class/powercap/intel-rapl*/name" in both cases. thanks, rui > > Is this a bug? > Do you know what may cause this? > > If you need more info to help me help you guys with this (if it's > truly an > issue), please let me know. > > Thanks, > > -Kenny > > ---- > Mar 22 05:02:48 xps-7390 kernel: [ 0.756890] RAPL PMU: API unit is > 2^-32 Joules, 3 fixed counters, 655360 ms ovfl timer > Mar 22 05:02:48 xps-7390 kernel: [ 0.756892] RAPL PMU: hw unit of > domain pp0-core 2^-14 Joules > Mar 22 05:02:48 xps-7390 kernel: [ 0.756893] RAPL PMU: hw unit of > domain package 2^-14 Joules > Mar 22 05:02:48 xps-7390 kernel: [ 0.756894] RAPL PMU: hw unit of > domain pp1-gpu 2^-14 Joules > Mar 22 05:02:48 xps-7390 kernel: [ 2.178267] intel_rapl_common: > Found RAPL domain package > Mar 22 05:02:48 xps-7390 kernel: [ 3.056499] intel_rapl_common: > Found RAPL domain package > Mar 22 05:02:48 xps-7390 kernel: [ 3.058417] intel_rapl_common: > Found RAPL domain core > Mar 22 05:02:48 xps-7390 kernel: [ 3.062290] intel_rapl_common: > Found RAPL domain uncore > Mar 22 05:17:50 xps-7390 kernel: [ 1.770794] RAPL PMU: API unit is > 2^-32 Joules, 3 fixed counters, 655360 ms ovfl timer > Mar 22 05:17:50 xps-7390 kernel: [ 1.770799] RAPL PMU: hw unit of > domain pp0-core 2^-14 Joules > Mar 22 05:17:50 xps-7390 kernel: [ 1.770802] RAPL PMU: hw unit of > domain package 2^-14 Joules > Mar 22 05:17:50 xps-7390 kernel: [ 1.770814] RAPL PMU: hw unit of > domain pp1-gpu 2^-14 Joules > Mar 22 05:17:50 xps-7390 kernel: [ 3.176324] intel_rapl_common: > Found RAPL domain package > Mar 22 05:17:50 xps-7390 kernel: [ 4.060045] intel_rapl_common: > Found RAPL domain package > Mar 22 05:17:50 xps-7390 kernel: [ 4.061739] intel_rapl_common: > Found RAPL domain core > Mar 22 05:17:50 xps-7390 kernel: [ 4.063129] intel_rapl_common: > Found RAPL domain uncore > Mar 22 05:28:05 xps-7390 kernel: [ 1.770320] RAPL PMU: API unit is > 2^-32 Joules, 4 fixed counters, 655360 ms ovfl timer > Mar 22 05:28:05 xps-7390 kernel: [ 1.770326] RAPL PMU: hw unit of > domain pp0-core 2^-14 Joules > Mar 22 05:28:05 xps-7390 kernel: [ 1.770329] RAPL PMU: hw unit of > domain package 2^-14 Joules > Mar 22 05:28:05 xps-7390 kernel: [ 1.770332] RAPL PMU: hw unit of > domain pp1-gpu 2^-14 Joules > Mar 22 05:28:05 xps-7390 kernel: [ 1.770335] RAPL PMU: hw unit of > domain psys 2^-14 Joules > Mar 22 05:28:05 xps-7390 kernel: [ 3.148050] intel_rapl_common: > Found RAPL domain package > Mar 22 05:28:05 xps-7390 kernel: [ 4.043621] intel_rapl_common: > Found RAPL domain package > Mar 22 05:28:05 xps-7390 kernel: [ 4.045295] intel_rapl_common: > Found RAPL domain core > Mar 22 05:28:05 xps-7390 kernel: [ 4.046823] intel_rapl_common: > Found RAPL domain uncore > Mar 22 05:37:11 xps-7390 kernel: [ 1.635660] RAPL PMU: API unit is > 2^-32 Joules, 4 fixed counters, 655360 ms ovfl timer > Mar 22 05:37:11 xps-7390 kernel: [ 1.635667] RAPL PMU: hw unit of > domain pp0-core 2^-14 Joules > Mar 22 05:37:11 xps-7390 kernel: [ 1.635670] RAPL PMU: hw unit of > domain package 2^-14 Joules > Mar 22 05:37:11 xps-7390 kernel: [ 1.635673] RAPL PMU: hw unit of > domain pp1-gpu 2^-14 Joules > Mar 22 05:37:11 xps-7390 kernel: [ 1.635676] RAPL PMU: hw unit of > domain psys 2^-14 Joules > Mar 22 05:37:11 xps-7390 kernel: [ 3.043397] intel_rapl_common: > Found RAPL domain package > Mar 22 05:37:11 xps-7390 kernel: [ 4.043265] intel_rapl_common: > Found RAPL domain package > Mar 22 05:37:11 xps-7390 kernel: [ 4.045524] intel_rapl_common: > Found RAPL domain core > Mar 22 05:37:11 xps-7390 kernel: [ 4.048153] intel_rapl_common: > Found RAPL domain uncore > ----
