Public bug reported:
[Impact]
The intel_pstate module should not be loaded when OOB mode for P-state
control is enabled, but currently the Noble kernel is only able to
detect OOB mode up to Emerald Rapids CPUs. This patch enables detection
for Granite Rapids/Sierra Forest CPUs.
[Fix]
Cherry pick 3ca2a3d1e727 ("cpufreq: intel_pstate: Support Granite Rapids
and Sierra Forest OOB mode") into the Noble tree.
[Test plan]
Build tested only.
[Where problems could occur]
Risk of regression seems very low, but problems here could manifest as
the intel_pstate driver misbehaving on Sierra Forest/Granite Rapids
systems.
