Hello Mario.
The following commits were pulled into v5.18.11:
``` $ git log --oneline --no-merges v5.18.10..v5.18.11 | grep ACPI 2783414e6ef7 ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported 3068cfeca3b5 ACPI: CPPC: Only probe for _CPC if CPPC v2 is acked 8beb71759cc8 ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported 13bb696dd2f3 ACPI: CPPC: Check _OSC for flexible address space ```
and now this happens:
``` $ sudo modprobe amd-pstate shared_mem=1 modprobe: ERROR: could not insert 'amd_pstate': No such device ```
With v5.18.10 this worked just fine.
In your upstream commit 8b356e536e69f3a4d6778ae9f0858a1beadabb1f you write:
``` If there is additional breakage on the shared memory designs also missing this _OSC, additional follow up changes may be needed. ```
So the question is what else should be pulled into the stable tree to unbreak amd-pstate?
Thanks.
