[PATCH v3 0/3] Add support for Zen 6 client EPP tunings
Posted by Mario Limonciello 2 weeks, 2 days ago
From: Mario Limonciello (AMD) <superm1@kernel.org>

Zen6 client platform firmware uses EPP values differently than previous
platforms. To optimize performance and power consumption tunings are
applied that match platform characteristics.

v3:
 * Enhancements suggested by Prateek to patch 1

Mario Limonciello (AMD) (3):
  cpufreq/amd-pstate: Show a warning if missing EPP tunings
  cpufreq/amd-pstate: Add per SoC and per core type EPP tuning values
  cpufreq/amd-pstate: Add EPP tunings for Zen6 client platforms
