tools/power/x86/intel-speed-select: v1.14 release

2023-02-03T09:01:50+00:00

This release adds following change:
- Minor fixes for coverity static analysis
- Don't read cpufreq on offline CPUs
- SST turbo-freq enable on auto mode when user disables SMT from
kernel command line
- Fix uncore frequency display
- Set uncore frequency max/min limits on perf level change

tools/power/x86/intel-speed-select: Adjust uncore max/min frequency

2023-02-03T09:01:50+00:00

When perf level is changed, uncore limits can change. Set the uncore
limits via Linux uncore sysfs, when user changes perf level with
-o option.

tools/power/x86/intel-speed-select: Add Emerald Rapid quirk

2023-02-03T09:00:24+00:00

Need memory frequency quirk as Sapphire Rapids in Emerald Rapids.
So add Emerald Rapids CPU model check in is_spr_platform().

tools/power/x86/intel-speed-select: Fix display of uncore min frequency

2023-02-03T09:00:24+00:00

Uncore P1 is not uncore minmum frequency. This is uncore base frequency.
Correct display from uncore-frequency-min(MHz)
to uncore-frequency-base(Mhz).

To get uncore min frequency use mailbox command
CONFIG_TDP_GET_RATIO_INFO. Use this mailbox to get uncore frequency
limits when present.

tools/power/x86/intel-speed-select: turbo-freq auto mode with SMT off

2023-02-03T08:57:10+00:00

When SMT is disabled from kernel command line, sibling CPUs still
appears in the sysfs as offline CPUs. This is a problem when turbo-freq
is enabled in auto mode. They are still assigned to CLOS value
of 3 as they are still in the present CPU list. But they are not in the
sibling list of a CPU. When the CPU is a high priority CPU, because of
sibling it will be still set to CLOS to 3 as CLOS is assigned at core
level not at CPU level.

So, avoid setting CLOS 3 to offline CPU.

tools/power/x86/intel-speed-select: cpufreq reads on offline CPUs

2023-02-03T08:57:07+00:00

Due to some recent kernel changes, reading cpufreq attributes like
scaling_max_freq on offline CPUs returns error. So avoid reading
cpufreq attributes on offline CPUs.
