---------------
thermald (1.9.1-1ubuntu0.2) focal; urgency=medium

  * Performance workaround for Dell 7390 2-in-1 Ice Lake (LP: #1874933)
   - 5.4 kernel added support for "Processor thermal device" for Ice Lake
     via the PPCC power tables. The power table specified for Dell 7390
     2-in-1 specifies this as 9W so thermald will limit it to this.
     This is a workaround that will ignore power limits less than the
     power up power limit to workaround this throttling. Requires a
     couple of prerequisite patches to apply and final 2 patches for
     the fix.
   - eeadf7d2efe Restore to min state on deactivation without
     depending on hardware state
   - 9a6dc27879a Clean up the code and documentation
   - f7db4342933 Avoid polling power in non PPCC case
   - c3461690eaf Ignore invalid PPCC max power limit
