@Chris,
82609c7) it looks like refactoring but also contains codes to make passive 
police 1 as default.
the kernel part is also SRUed, LP1966089. 
for this bug and 1982073, i cherry-picked some,these are essential and make 
jammy-2.4.9 and 2.5.0 are almost identical.

I have ran some unit tests for rapl/powerclamp/intel_pstate.
also ask Dell/User to verify 2.5.0 with supported kernel.

Title:
  thermald prematurely throttling GPU

Status in thermald package in Ubuntu:
  Fix Released
Status in thermald source package in Jammy:
  In Progress

Bug description:
  [Impact]
   * thermald prematurely throttling GPU

  [Test Plan]
   * Run game on the target machine.
   * the FPS must not be throttled below 20FPS.

  [Where problems could occur]
   * better support for Passive Policy. currently passive policy 1 is supported 
and it should have a bug if the machine only enable pssive policy 2.

  I got a new game and started playing it
  It would run at over 100 FPS solidly some of the time and then cyclically dip 
down to below 20 FPS for a few minutes

  I determined that it was thermald trying to keep my GPU below 70°C
  to determine this I sudo systemctl stop thermald
  The game ran solidly and consistently with the GPU at 75°C

  This is well below the specs set by the manufacturer and perhaps
  unreasonably low for a laptop

  But more importantly I was given no indication this was happening. I
  had to sleuth it out myself.

  Perhaps it is impossible to determine good defaults for all hardware,
  I don't know. However without an indication that this is happening
  there will be a lot of people with a mysteriously broken experience.
  This was extremely difficult for me to find and I had several friend
  who are experts on linux gaming and video drivers trying to track this
  down. I discovered it by luck and perseverance.

  This absolutely needs some sort of indication and hopefully a way to
  remedy it from the GUI. ideally it would set thermal limits that are
  more in line with what the device is designed for and not a
  conservative default if at all possible.
