[v3] Enable amd-pstate active mode by default

[PATCH v3 0/3] Enable amd-pstate active mode by default

Posted by Mario Limonciello 2 years, 7 months ago

Active mode for amd-pstate has shown enough success now that it makes sense
to enable it by default on client systems.

This series introduces a new kernel configuration option to set the default
policy for amd-pstate modes for a kernel.

Server systems will by identified by the PM preferred profile and still be
set as disabled by default for now.

v2->v3:
 * Drop patch 4; Intel intentionally doesn't want intel-pstate on SOHO
   server
 * Move symbols from patch 1 into patch 2
 * Add tags
Mario Limonciello (3):
  ACPI: CPPC: Add definition for undefined FADT preferred PM profile
    value
  cpufreq: amd-pstate: Set a fallback policy based on preferred_profile
  cpufreq: amd-pstate: Add a kernel config option to set default mode
