Subject: [PATCH] cpufreq: intel_pstate: Support Emerald Rapids OOB mode
Date: Wed, 29 May 2024 22:53:30 -0700 [thread overview]
Message-ID: <20240530055330.1279381-1-srinivas.pandruvada@linux.intel.com> (raw)
Prevent intel_pstate to load when OOB (Out Of Band) P-states mode is
enabled in Emerald Rapids. The OOB identifying bits are same as the
prior generation CPUs like Sapphire Rapids servers. So, also add Emerald
Rapids to intel_pstate_cpu_oob_ids list.
