2023-03-22tools/power/x86/intel-speed-select: Use cgroup v2 isolationSrinivas Pandruvada
On supported systems, it is possiible to isolate CPUs instead of CPU online/offline. This is optional and can be specified using -g option when running as daemon or in combination with -o option for SST-PP level change. CPU isolation doesn't isolate IRQs. So IRQs needs to be moved away from isoolated CPUs. This can be done via IRQ sysfs or irqbalance daemon. The IRQ balance daemon is also capable to parse thermal HFI messages to move IRQs away from CPUS, which are supposed be isolated. But this requires version released after July 2022.

2023-03-22tools/power/x86/intel-speed-select: Add missing free cpusetSrinivas Pandruvada
During perf level change cpuset is allocated but not freed. Add free_cpu_set() in success and failure path. Although this is not an issue, as the program will exit after processing of online/offline, but for completeness add the free_cpu_set().

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.
