2024-07-07tools/power/x86/intel-speed-select: Set TRL MSR in 100 MHz unitsSrinivas Pandruvada
When SST-TF is disabled in auto mode, the performance is getting limited. This is caused by wrong programming of Turbo Ratio Limit (TRL) MSR. This MSR always accepts the frequency ratio in 100 MHz unit. When the TPMI is sending TRL in 1 MHz unit, change to 100 MHz, before updating TRL MSR.

2024-04-29tools/power/x86/intel-speed-select: SST BF/TF support per levelSrinivas Pandruvada
SST BF and TF can be enabled/disabled per level. So check the current level support from the mask of supported levels. This change from a single level to mask for info.sst_tf_support and info.sst_tf_support is indicated by API version change. Use as mask for API version above 2. In this way there is no change in behavior when running on older kernel with API version 2. Since the tool can support now API version 3, update the supported API version.

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.

SST control is power-domain based rather than cpu based, on all the systems including Sapphire Rapids and ealier. SST core APIs uses cpu id as parameter, and use the underlying pkg_id and die_id information to find a power domain, this is not straight forward and introduces obscure logics in the code.
