tools/power/x86: A tool to validate Intel Speed Select commands The Intel(R) Speed select technologies contains four features. Performance profile:An non architectural mechanism that allows multiple optimized performance profiles per system via static and/or dynamic adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS in the documentation. Base Frequency: Enables users to increase guaranteed base frequency on certain cores (high priority cores) in exchange for lower base frequency on remaining cores (low priority cores). aka PBF in the documenation. Turbo frequency: Enables the ability to set different turbo ratio limits to cores based on priority. aka FACT in the documentation. Core power: An Interface that allows user to define per core/tile priority. There is a multi level help for commands and options. This can be used to check required arguments for each feature and commands for the feature. To start navigating the features start with $sudo intel-speed-select --help For help on a specific feature for example $sudo intel-speed-select perf-profile --help To get help for a command for a feature for example $sudo intel-speed-select perf-profile get-lock-status --help Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Acked-by: Len Brown <len.brown@intel.com> Acked-by: Rafael J.

When HFI is supported there is no need for polling to check config level change. Subscribe to Linux thermal netlink messages and process message: THERMAL_GENL_EVENT_CPU_CAPABILITY_CHANGE.

kbuild: replace $(if A,A,B) with $(or A,B) $(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Nicolas Schier <nicolas@fjasle.eu>
