** Description changed:

  [ Impact ]
  
-  * Changing the Power Mode from PPD (Perfomance/Balance/Power Saver),
- the USTT(User Selectable Thermal Table) setting will also be changed.
- Add the feature to synchronize Power Mode and ACPI ThermalManagement
+  * The amd-pstate driver will change CPU frequency control mechanism
+ against the different power mode setting in the PPD. To support the
+ mechanism fully it needs to adapt correct thermal management policy in
+ the BIOS which is determined by the USTT(User Selectable Thermal Table),
+ and it is reflected by the platform profile. The feature will change the
+ ThermalManagement setting after reboot when user change the power mode
  setting.
  
  The mapping relationship power mode and platform profiles:
  performance <-> performance
  balanced <-> balanced/balanced_performance/cool
  power saver <-> low-power/quiet
  
  [ Test Plan ]
  
-  * On machine supports ACPI platform profile, which has sysfs node
+  * On AMD Strix Point/Krackan Point platform which has sysfs node
  /sys/firmware/acpi/platform_profile
  
   * Try to modify power mode by $ sudo powerprofilectl set <power-mode>
  
   * Check if /sys/firmware/acpi/platform_profile being updated
  
-  * Check if BIOS update the ThermalManagement setting by $ fwupdmgr get-
- bios-setting ThermalManagement after reboot
+  * After reboot, check if BIOS update the ThermalManagement setting by $
+ fwupdmgr get-bios-setting ThermalManagement
  
  [ Where problems could occur ]
  
-  * The change tries to map the power mode and platform_profile. It
- doesn't work if the platform profile is unexpected
+  * The platform will list supported platform_profile in
+ /sys/firmware/acpi/platform_profile_choices, the DPP power mode should
+ map to one of it, otherwise, it can't select the correct thermal policy.
+ If the platform set the unexpected string which the mapping is not
+ defined in the PPD. The thermal policy can't be switched successfully.

Title:
  Can't recognize custom ACPI platform profile

Status in OEM Priority Project:
  New
Status in power-profiles-daemon package in Ubuntu:
  In Progress

Bug description:
  [ Impact ]

   * The amd-pstate driver will change CPU frequency control mechanism
  against different power mode setting in the PPD. To support the
  mechanism fully it needs to adapt correct thermal management policy in
  the BIOS which is determined by the USTT(User Selectable Thermal
  Table), and it is reflected by the platform profile. The feature will
  change the ThermalManagement setting after reboot when user change the
  power mode setting.

  The mapping relationship power mode and platform profiles:
  performance <-> performance
  balanced <-> balanced/balanced_performance/cool
  power saver <-> low-power/quiet

  [ Test Plan ]

   * On AMD Strix Point/Krackan Point platform which has sysfs node
  /sys/firmware/acpi/platform_profile

   * Try to modify power mode by $ sudo powerprofilectl set <power-mode>

   * Check if /sys/firmware/acpi/platform_profile being updated

   * After reboot, check if BIOS update the ThermalManagement setting by
  $ fwupdmgr get-bios-setting ThermalManagement

  [ Where problems could occur ]

   * The platform will list supported platform_profile in
  /sys/firmware/acpi/platform_profile_choices, the DPP power mode should
  map to one of it, otherwise, it can't select the correct thermal
  policy. If the platform set the unexpected string which the mapping is
  not defined in the PPD. The thermal policy can't be switched
  successfully.
