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.

tools/power/x86/intel-speed-select: Fix invalid core mask The core mask display is wrong in some cases. This is showing more cpus than the mask has. This is because mask is 64 bit but it used with BIT() macro to get the presence of CPU which doesn't support unsigned long long. Added a new macro for BIT_ULL and use that to get the presence of a CPU. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

With this the result field is changed to string interpreting every non zero value as errors. But these commands display on zero (>0) result. For example before this commit the display was: package-1 die-0 cpu-14 get-config-levels:4 Here the get-config-levels is interpreted as error and displayed as error with the above commit: package-1 die-0 cpu-14 get-config-levels:failed(error 4) Fix this issue by not using isst_display_result() to display such results, but define a new function which formats this data and prints.

tools/power/x86/intel-speed-select: Support platform with limited Intel(R) Speed Select There are some platforms, where there limited support of Intel(R) SST features. Here perf-profile has only one base configuration and limited support of commands. But still has support for discovery of base-freq and turbo-freq features. So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies. Here present base frequency by reading cpufreq base freq and turbo frequency by reading MSR 0x1AD. - Don't display any field, which has value == 0.
