@Andreas, 
for the test 1, actually i can't hit the issue on my side so just show the 
benchmark between the proposded and upstream version. 
i can ran the previous version to compare.
i still need Colette's help to verify but didnt get the reply.

for test 2, it just to run thermald and check if the cpu is throttled.
please review this in LP#1995606, #25.

Title:
  thermald prematurely throttling GPU

Status in thermald package in Ubuntu:
  Fix Released
Status in thermald source package in Jammy:
  Fix Committed

Bug description:
  [Impact]
   * thermald prematurely throttling GPU

  [Fix]
  This fix is removed the code refactoring part and keep the necessary.

  (patch: 0009-Install-passive-default.patch)
  82609c7) Separate Adaptive engine and GDDV

  [Test Plan]
  Test1,
   * Run game on the target machine.
   * the FPS must not be significantly reduced.
  Test2,
   * Run on others platform, ADL/TGL/CML/CFL/KBL.
   * Use monitoring tool(e.g. s-tui) and stress-ng to verify if the machine 
runs normally.

  [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.
