2026-08-19T02:09:42+00:00

Pull x86 cpuid updates from Borislav Petkov:

 - Get rid of static_cpu_has() - one less API to care about testing CPU
   features

 - Unify the handling of CPU core types (performance, efficient, etc) by
   mapping the vendor-specific types to Linux ones

 - Continuation of the work of Ahmed Darwish to centralize CPUID leaf
   representation

platform/x86: ISST: Add a NULL check for sst_inst[]

2026-08-18T14:30:29+00:00

To be consistent with other places, add a NULL check for failed socket
loading by checking isst_common.sst_inst[].

platform/x86: ISST: Return error during profile addition

2026-08-18T14:30:28+00:00

If sst_add_perf_profiles() fails for memory allocation, it continues
to allow SST-CP (core-power) feature. But in practice this is not
very useful as to achieve some frequencies via SST-CP, an SST-PP
(perf-profile) level change is required.

platform/x86: ISST: Just allow 2 bits for SST feature enable

2026-08-18T14:30:27+00:00

Currently only 2 features SST-TF and SST-BF are supported, so only allow
bit 0 and bit 1.

platform/x86: ISST: Use PP level enable mask

2026-08-18T14:30:25+00:00

Add check for enabled levels only when reading MMIO. Some levels can be
disabled by BIOS. If the level is not enabled, return an error.

Reset the enable and allowed level masks if there is a failure to add a
perf level.
