This is meant to be a v4 of Laszlo's S3 series. (I hope
my changes are not too unwelcome! And, appologies for
anything I may have broken!)
The main improvements I made:
* Consolodate 'fixed' RAM usage at 8MB
* Declare fixed memory usage in PCDs & FDF files
* Don't decompress FVs on S3 resume
* Reduce runtime S3 RAM usage overhead to < 1MB
* Remove EmuNvramLib
I retained many of Laszlo's patches, but some were
modified.
I'm still not too happy with Ovmf/AcpiS3SaveDxe.
It would be nice to fixup the main AcpiS3SaveDxe so
we could use it directly rather than having a custom
version in OVMF.
I dropped the portion of the series that saves memory
when S3 is disabled in QEMU. I'd like to push it out,
and look at it as a follow-up to this series.
One other small change that I wanted to make, but I did
not get to is that I wanted to look at the PIIX4 sleep
register rather than CMOS for detecting an S3 resume.
