platform/x86/amd: pmc: Drop SMU F/W match for Cezanne
JIRA: https://issues.redhat.com/browse/RHEL-102860 commit 5b9e075 Author: Mario Limonciello <mario.limonciello@amd.com> Date: Thu Jul 24 13:51:08 2025 -0500 platform/x86/amd: pmc: Drop SMU F/W match for Cezanne Chris reported that even on a BIOS that has a new enough SMU F/W version there is still a spurious IRQ1. Although the solution was added to SMU F/W 64.66.0 it turns out there needs to be a matching SBIOS change to activate it. Thus Linux shouldn't be avoiding the IRQ1 workaround on newer SMU F/W because there is no indication the BIOS change is in place. Drop the match for 64.66.0+ and instead match all RN/CZN/BRC (they all share same SMU F/W). Adjust the quirk infrastructure to allow quirking the workaround on or off and also adjust existing quirks to match properly. Unfortunately this may cause some systems that did have the SBIOS change in place to regress in keyboard wakeup but we don't have a way to know. If a user reports a keyboard wakeup regression they can run with amd_pmc.disable_workarounds=1 to deactivate the workaround and share DMI data so that their system can be quirked not to use the workaround in the upstream kernel.
