2020-01-20tools/power/x86/intel-speed-select: Fix result display for turbo-freq auto modeSrinivas Pandruvada2-8/+10
The turbo-freq enable with auto mode, prints result for the last possible CPU, which is not correct when either CPU is not present or user wants command to be limited to a single die/package. For example, in the below command user wants to limit to die/package 0, but the "turbo-freq --auto" result is displayed using the other package. $ sudo intel-speed-select -c 0 turbo-freq enable -a Intel(R) Speed Select Technology package-0 die-0 cpu-0 turbo-freq enable:success package--1 die-0 cpu-31 turbo-freq --auto enable:success Since we do have to traverse all CPUs, don't display CPU info for "turbo-freq --auto", as we already displayed the result for turbo-freq enable with the CPU information.

It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level.

2019-11-07tools/power/x86/intel-speed-select: Support platform with limited Intel(R) ↵Srinivas Pandruvada4-60/+113
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.
