dmesg | grep ENERGY [ 0.061976] ENERGY_PERF_BIAS: Set to 'normal', was 'performance' [ 0.061976] ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8) > checked on the slight chance I had an alias causing problems etc, but > that wasn't the case: > > $ 'dmesg'|'grep' ENERGY > [ 0.010557] ENERGY_PERF_BIAS: Set to 'normal', was 'performance' > ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8) > $ dmesg --version && grep --version > dmesg from util-linux 2.25.2 > grep (GNU grep) 2.20 $ dmesg --version && grep --version dmesg from util-linux 2.20.1 grep (GNU grep) 2.20 I've upgraged util-linux (for dmesg) on the other box: $ dmesg --version && grep --version dmesg from util-linux 2.25.1 grep (GNU grep) 2.18 and now I get: dmesg | grep -E "[id]TLB" [ 0.269607] Last level iTLB entries: 4KB 512, 2MB 1024, 4MB 512 Last level dTLB entries: 4KB 1024, 2MB 1024, 4MB 512, 1GB 0 So I'd say it looks like a regression in dmesg itself. -- Regards/Gruss, Boris.
