@Robie,
For the TCC,
I have replied fo Jamssy,
~~~
TCC adjustment has been offloaded to kernel driver intel_tcc_cooling,
it's registered as a thermal cooling device.
2eb87d75f980) thermal/drivers/intel: Introduce tcc cooling driver.
This was merged to mainline since 5.13. Focal is using hwe-5.15.

commit fdf4f2fb8e8990c131b2b1a5a9c03681bb16e87a
Author: Srinivas Pandruvada <srinivas.pandruv...@linux.intel.com>

drivers: thermal: processor_thermal_device: Export sysfs interface
for TCC offset
so a backport to focal (which is planned) should be safe in that regard.

Is there any question I missed? thanks

Title:
Upgrade thermald to 2.5.1
Status in thermald package in Ubuntu:
Fix Released
Status in thermald source package in Jammy:
Incomplete
Bug description:
[Justification]
The purpose of this bug is that prevent the regression in the future.
The automatic test scripts are better for the future SRU and is still on the
planning.
[Test case]
For each supported CPU series (RPL/ADL/TGL/CML/CFL/KBL) the following tests
will be run on machines in the CI lab:
1. Run stress-ng, and observe the temperature/frequency/power with s-tui
- Temperatures should stay just below trip values
- Power/performance profiles should stay roughly the same between old
thermald and new thermald (unless specifically expected eg: to fix
premature/insufficient throttling)
2. check if thermald could read rules from /dev/acpi_thermal_rel and generate
the xml file on /etc/thermald/ correctly.
- this depends on if acpi_thermal_rel exist.
- if the machine suppots acpi_thermal_rel, the "thermal-conf.xml.auto"
could be landed in etc/thermald/.
- if not, the user-defined xml could be created, then jump to (3).
- run thermald with --loglevel=debug, and compare the log with xml.auto
file. check if the configuration could be parsed correctly.
3. check if theramd-conf.xml and thermal-cpu-cdev-order.xml can be loaded
correctly.
- run thermald with --loglevel=debug, and compare the log with xml files.
- if parsed correctly, the configurations from XML files would appear in
the log.
4. Run unit tests, the scripts are under test folder, using emul_temp to
simulate the High temperatue and check thermald would throttle CPU through the
related cooling device.
- rapl.sh
- intel_pstate.sh
- powerclamp.sh
- processor.sh
5. check if the power/frequency would be throttled once the temperature reach
the trip-points of thermal zone.
6. check if system would be throttled even the temperature is under the
trip-points.
