2023-03-22tools/power/x86/intel-speed-select: Introduce isst-core-mbox.cZhang Rui
isst-core.c should contain generic core APIs only. Platform specific implementations/configurations should be removed from this file. Introduce isst-core-mbox.c and move all mbox/mmio specific functions to this file. Introduce struct isst_platform_ops which contains a series of callbacks that used by the core APIs but need platform specific implementation. No functional changes are expected.

2023-03-22tools/power/x86/intel-speed-select: Always invoke isst_fill_platform_infoZhang Rui
isst_fill_platform_info fills platform specific information. And it is the proper place to set platform specific callbacks, as done in next patch. As the platform specific callbacks are needed in all cases, including isst_print_platform_information. The best way to achieve both is to invoke isst_fill_platform_info unconditionally, and make isst_print_platform_information leverage the data already filled. No functional changes are expected.

2023-03-22tools/power/x86/intel-speed-select: Move mbox functions to isst-core.cZhang Rui
isst-config.c should only contain generic code. Move mbox functions which are platform specific code to isst-core.c. As there are some platform specific parameters set via generic application options, introduce isst_update_platform_param to pass these parameters to platform specific code.

2023-03-22tools/power/x86/intel-speed-select: Improve isst_print_extended_platform_infoZhang Rui
The main thing done in isst_print_extended_platform_info is to get the isst feature status by checking one of the power domains of the platform. This can be done using the for_each_online_power_domain_in_set() function, which makes the code clean and easier to read. No functional changes are expected.

2023-03-22tools/power/x86/intel-speed-select: Rename for_each_online_package_in_setZhang Rui
for_each_online_package_in_set is actually used to invoke callback for each power domain. This is not a problem when there is a single power domain within a package/die, but it does not reflect the truth in multi-punit case. Rename for_each_online_package_in_set to for_each_online_power_domain_in_set. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
2023-03-22tools/power/x86/intel-speed-select: Introduce support for multi-punitZhang Rui
New platforms may have more than 1 punit in a Package/Die, thus it can have multiple power domains in a Package/Die. Package id and die id is not sufficient to refer to a specific Power domain. Introduce support for multi-punit per package/die.

2023-03-22tools/power/x86/intel-speed-select: Introduce isst_is_punit_valid()Zhang Rui
Introduce isst_is_punit_valid() for checking a valid domain. For current platforms, it requires a punit 0 in a valid Package/Die. No functional changes are expected.

2023-03-22tools/power/x86/intel-speed-select: Introduce punit to isst_idZhang Rui
Punit id can also be retrieved from ISST_IF_GET_PHY_ID. punit id is unique within a Package/Die, and together with Package id and Die id, they can be used to refer to a specific SST power domain. For current platforms, Punit id is always Zero. So no functional changes are expected for the current platforms. While here, prevent issuing IOCTL if the file /dev/isst_interface can't be opened.

2023-03-22tools/power/x86/intel-speed-select: Follow TRL nameing for FACT infoZhang Rui
SST-TF high priority core count and ratios and low priority core ratios are also per TRL level. Cleanup the code to follow the same nameing convention as TRL. This removes hardcoded TRL level names and variables. No functional changes are expected.

2023-03-22tools/power/x86/intel-speed-select: Unify TRL levelsZhang Rui
TRL supports different levels including SSE/AVX2/AVX512. Avoid using hardcoded level name and structure fields, so that a loop can be used to parse each TRL level instead. This reduces several lines of source code. No functional changes are expected.

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

2023-02-03tools/power/x86/intel-speed-select: turbo-freq auto mode with SMT offSrinivas Pandruvada
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.
