** Description changed:
[ Impact ]
- * To make thermald to support Intel PTL platform and support ITMT3
- policy when it is present
+ * The thermald will not be active on PTL platform
+
+ * The thermald won't enable ITMT3 even the processor can support it.
+
+ * The advantage of ITMT3 can be found in https://edc.intel.com/content/www/us/en/design/ipla/software-development-platforms/client/platforms/alder-lake-desktop/12th-generation-intel-core-processors-datasheet-volume-1-of-2/004/intel-turbo-boost-max-technology-3-0/
[ Test Plan ]
* On Intel PTL platform with ITMT3.0 policy configured
* Boot into Ubuntu
* Stop the default thermald by $ sudo systemctl stop thermald
* run the thermlad with extra parameter $ sudo thermald --systemd
--dbus-enable --adaptive --log-level=info
* check the journalctl log to confirm that thermald apply the policy
successfully
1. Make sure to see ITMT3.0 policy defined in the APAT table

ITMT1.0 and ITMT2.0. For platform within ITMT3.0 configured, might
change the thermal behavior.
[ Other Info ]
* ITMT stands for Intel Turbo Boost Max Technology, a feature that
identifies the best-performing cores on a processor and directs
workloads to them for increased single-threaded performance. This
technology assigns a higher priority to the fastest cores, ensuring that
demanding tasks get the maximum possible speed on those select cores,
while other cores handle less intensive work or remain idle.
