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.

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.

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.

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.

tools/power/x86/intel-speed-select: Improve core-power result and error display This change adds improved error display and handling for commands related to core-power feature. The changes include: - Replace perror with helpful error message - Use ordered priority for SKX based platform by default as the proportional priority is not supported - Don't show weight and epp in help and also give error when user tries to set them in SKX based platforms - Range check for epp and weights and display error Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

tools/power/x86/intel-speed-select: Refuse to disable core-power when getting used The turbo-freq feature is dependent on the core-power feature. If the core-power feature is disabled while the turbo-freq feature is enabled, this will break the turbo-freq feature. This is a firmware limitation, where they can't return error under this scenario. So when trying to disable core-power, make sure that the turbo-freq feature is not enabled. If it enabled, return error if user is trying to disable the core-power feature.

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.
