Title:
  Can't recognize custom ACPI platform profile

Status in OEM Priority Project:
  New
Status in power-profiles-daemon package in Ubuntu:
  Fix Released
Status in power-profiles-daemon source package in Noble:
  Fix Committed

Bug description:
  [ Impact ]

   * The kernel 6.14+ support new string 'custom' platform profile to
  accommodate multiple driver to support different positions.

   * On Dell's platform have a BIOS option that configures the user
  selectable thermal tables which are read by the dell-pc driver. It's
  possible to boot up with the two drivers having different values and
  then the power slider being in an undefined position

   * PPD had to be modified to account for this new string. If PPD isn't
  modified then the system will be in an undefined power state.

  [ Test Plan ]

   * Checkbox job com.canonical.certification::power-
  management/switch_power_mode can verify if all platform supported
  profiles can be set and read correctly.

   *
  https://github.com/canonical/checkbox/blob/main/providers/base/units/power-
  management/jobs.pxu#L119

   * Add the job into kernel SRU plan to ensure the test coverage

  [ Where problems could occur ]

   * The platform will list supported platform_profile in
  /sys/firmware/acpi/platform_profile_choices, the PPD 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.

  [ Other Info ]

   * Upstream commit: https://gitlab.freedesktop.org/upower/power-
  profiles-daemon/-/commit/6b565b0b05a2bc92e3c546a567b394f415937265

   * The patch is in 25.04 and 25.10 already.

   * To the kernel without platform_profile node [1], the user
  experience is just as before.
