I submitted a firmware update for sound/sof, the tracking bug number is: https://bugs.launchpad.net/bugs/1847250
Recently we found this update introduced one problem for cometlake platforms, cometlake need to check PV bit when loading the firmware, but this update doesn't set the PV bit for cometlake, as a result, on cometlake platforms, it always fails to load the firmware.
So we should revert this update |
SRU Justification
Impact: An update to the sound sof firmware does not set the PV bit for cometlake, and thus will not load. This is a regression on cometlake platforms.
Fix: Revert the update.
Test Case: Check that the firmware will load on affected platforms.
Regression Potential: This fixes a regression on cometlake paltforms, but will regress the platforms fixed by the patch being reverted.
