[v4] OvmfPkg/PlatformPei: prefer etc/e820 for memory detection

[edk2-devel] [PATCH v4 0/3] OvmfPkg/PlatformPei: prefer etc/e820 for memory detection

Posted by Gerd Hoffmann 2 years, 4 months ago

Don't use cmos for memory detection if possible.
qemu provides the etc/e820 firmware config file
as alternative since 2013.

v4:
 - uncrustify & rebase to latest master.

v3:
 - fix CI failure.

v2:
 - fix lowmem detection.
 - pick up review tags.
 - add rfc patch to completely drop cmos support.
