[PATCH 0/2] intel_pstate: fix turbo not being used after a processor is rebooted

From: Pratyush Yadav
Date: Wed Dec 21 2022 - 10:52:30 EST


When a processor is brought offline and online again, it is unable to
use Turbo mode because the _PSS table does not contain the whole turbo
frequency range, but only +1 MHz above the max non-turbo frequency. This
causes problems when ACPI processor driver tries to set frequency
constraints. See patch 2 for more details.

Pratyush Yadav (2):
acpi: processor: allow fixing up the frequency for a performance state
cpufreq: intel_pstate: use acpi perflib to update turbo frequency
