Public bug reported: [ Impact ]
* Access to trying to access /sys/devices/system/cpu/intel_pstate/no_turbo on Skylake-X systems trigger an unchecked MSR access error: WRMSR to 0x199 (attempted to write 0x0000000100001300). [ Fix ] * Clean cherry-pick from upstream: ac4e04d9e378 cpufreq: intel_pstate: Unchecked MSR aceess in legacy mode [ Test Plan ] * Compiled. [ Where problems could occur ] * Regression in turbo management in intel hardware.
