Mario Limonciello fbd74d1689 ACPI: CPPC: Fix enabling CPPC on AMD systems with shared memory ... When commit 72f2ecb7ec ("ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported") was introduced, we found collateral damage that a number of AMD systems that supported CPPC but didn't advertise support in _OSC stopped having a functional amd-pstate driver. The _OSC was only enforced on Intel systems at that time. This was fixed for the MSR based designs by commit 8b356e536e ("ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported") but some shared memory based designs also support CPPC but haven't advertised support in the _OSC. Add support for those designs as well by hardcoding the list of systems. Fixes: 72f2ecb7ec ("ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported") Fixes: 8b356e536e ("ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported") Link: https://lore.kernel.org/all/3559249.JlDtxWtqDm@natalenko.name/ Cc: 5.18+ <stable@vger.kernel.org> # 5.18+ Reported-and-tested-by: Oleksandr Natalenko <oleksandr@natalenko.name> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Rafael J.
