2023-03-22tools/power/x86/intel-speed-select: Introduce TPMI interface supportZhang Rui
TPMI (Topology Aware Register and PM Capsule Interface) creates a flexible, extendable and software-PCIe-driver-enumerable MMIO interface for PM features. SST feature is exposed via the TPMI interface on newer Xeon platforms. Kernel TPMI based SST driver provides a series of new IOCTLs for userspace to use. Introduce support for the platforms that do SST control via TPMI interface. Compared with previous platforms, Newer Xeons also supports multi-punit in a package/die, including cpu punit and non-cpu punit. These have already been handled in the generic code.

isst-core.c should contain generic core APIs only. Platform specific implementations/configurations should be removed from this file.

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: 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.

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.

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.
