cpufreq: intel_pstate: Add Ice Lake server to out-of-band IDs
mainline inclusion from mainline-v5.16 commit cd23f02f category: feature bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I78I87 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d23f02f166892603eb9f2d488152b975872b682 Intel-SIG: commit cd23f02f cpufreq: intel_pstate: Add Ice Lake server to out-of-band IDs. Backport for intel-pstate driver ------------------------------------------------- Commit fbdc21e9 ("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.
