From 35b6f74fb47839627b5dc71d53c5630869774ee1 Mon Sep 17 00:00:00 2001 From: Adamos Ttofari Date: Fri, 12 Nov 2021 09:16:57 +0000 Subject: [PATCH] cpufreq: intel_pstate: Add Ice Lake server to out-of-band IDs Commit ea24557fe61d ("cpufreq: intel_pstate: Add Icelake servers support in no-HWP mode") enabled the use of Intel P-State driver for Ice Lake servers. But it doesn't cover the case when OS can't control P-States. Therefore, for Ice Lake server, if MSR_MISC_PWR_MGMT bits 8 or 18 are enabled, then the Intel P-State driver should exit as OS can't control P-States.
