Hi,I recall the last related discussion from February:
Years ago, the bug(*) for PEI variable driver was filed against OVMF
and it used to be one reason to block S4 support in OVMF. The bug is
fixed now, and there are several MemTypeInfo fixes merged into OVMF.
I'm curious about the current status of S4 support in OVMF. Is it
still considered as unsupported due to some other bugs?
* [edk2-devel] [PATCH 0/2] Improve hibernation safety
No patches needed to be merged (Alex was missing some commits that had
been upstreamed by then).
My understanding is that S4 should work at this point, although I've
never really tested it myself.
Thanks for the information. I was reviewing the libvirt descriptor for
ovmf and wondering if it's ready for the "acpi-s4" tag. Maybe it's a
good to give it a try.
