[PATCH] OvmfPkg/OvmfXen: Fix S3
Posted by Xenia Ragiadakou 9 months, 3 weeks ago 
Currently, resuming an S3 suspended guest results in the following
assertion failure:
ASSERT MdePkg/Library/PeiResourcePublicationLib/PeiResourcePublicationLib.c(41): MemoryLength > 0
This happens because some parts of the S3 suspend and resume paths
are missing in order for S3 to work. For instance, the variables
mS3AcpiReservedMemoryBase and mS3AcpiReservedMemoryBase are not
initialized, regions that are used on S3 resume are either missing
or not marked as ACPI NVS memory and can be corrupted by the OS.
This patch adds the missing parts based heavily on the existing S3
implementation of other virtual platforms.

For S3 support, the provision of fw_cfg is required in order for
suspend states to be retrieved.

Another issue noticed is that when CalibrateLapicTimer() is called
on S3 resume path, the shared info page is remapped to a different
guest physical address. This remapping happens under guest's feet,
so any subsequent attempt of the guest to access the shared info
page results in nested page faults. This patch removes any local
APIC timer initializion and calibration from S3 resume path.

Is it possible to have S3 work without fw_cfg? We normally disable
fw_cfg in QEMU when using it to start a Xen guest. We only enable fw_cfg
if we want to boot a kernel directly in HVM (like PV guest, called
Direct Kernel Boot in xl.cfg(5)).

But even trying the direct kernel boot method, I've got issue trying to
resume a suspended guest. I ran into:
    ASSERT /root/build/ovmf/UefiCpuPkg/Library/MpInitLib/MpLib.c(2093): (LibPcdGet64(9U) & (0x00000001 | 0x00000002)) == (0x00000001 | 0x00000002)

By the way, I'm using `xl` to boot a guest to test this patch.

So, I've got some question, which version of QEMU do you use, which work
with this patch?
What toolstack do you use to boot a guest?


Thanks,

Anyone care to review this?
