amd-pstate Dynamic EPP and raw EPP

From: Mario Limonciello <mario.limonciello@amd.com> Dynamic EPP allows the kernel to register amd-pstate as part of a platform profile. It will change EPP modes matching the user's preference to the platform profile sysfs files as well as power adapter state. Raw EPP allows userspace to write integers to energy_performance_preference. This series is based off superm1/linux.git bleeding-edge branch + https://lore.kernel.org/linux-pm/20250215005244.1212285-1-superm1@kernel.org/T/#t Mario Limonciello (5): cpufreq/amd-pstate: Add dynamic energy performance preference cpufreq/amd-pstate: add kernel command line to override dynamic epp cpufreq/amd-pstate: Add support for platform profile class cpufreq/amd-pstate: Add support for raw EPP writes cpufreq/amd-pstate-ut: Add a unit test for raw EPP .../admin-guide/kernel-parameters.txt | 7 + Documentation/admin-guide/pm/amd-pstate.rst | 41 ++- drivers/cpufreq/Kconfig.x86 | 13 + drivers/cpufreq/amd-pstate-ut.c | 58 ++++ drivers/cpufreq/amd-pstate.c | 291 ++++++++++++++++-- drivers/cpufreq/amd-pstate.h | 16 +- 6 files changed, 390 insertions(+), 36 deletions(-)
