[PATCH v2 0/2] x86/time: prefer CMOS over EFI_GET_TIME

Posted by Roger Pau Monne 2 months, 3 weeks ago

Hello,

Workaround a common issue with x86 EFI implementations having broken
EFI_GET_TIME methods, and only resort to EFI_GET_TIME if CMOS is not
available.

First patch splits some of the CMOS probe and fetch logic into a
separate helper, so that patch 2 that actually performs the ordering
change is cleaner.

Thanks, Roger.
