Title:
Fix the ACPI _CPC not found error from kernel dmesg on some dynamic
SSDT tables firmware
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
Some machines which have dynamically loaded SSDT tables, will not be loaded
and get the CPPC not worked.
[Fix]
Fix the regression by some load supports for CPPC from an SSDT dynamically
when _OSC reports CPPC v2. And make the "[\_SB.PR00._CPC], AE_NOT_FOUND" gone.
[Test]
Verified all the OEM dynamic table loaded or the "[\_SB.PR00._CPC],
AE_NOT_FOUND" error exist or not on demesg .
[Where problems could occur]
Low risk, It only helps to CPPC support loaded.
