[v2] Support 2 CpuMpPei/CpuDxe in One image

[edk2-devel] [PATCH V2 0/6] Support 2 CpuMpPei/CpuDxe in One image

Posted by Min Xu 1 year, 11 months ago

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3918

Above BZ reports an issue that commit 88da06ca triggers ASSERT in some
scenario. This patch-set is to fix this issue.

As commit 88da06ca describes TDVF BSP and APs are simplied and it can
simply use MpInitLibUp instead of MpInitLib. To achieve this goal, we
include 2 CpuMpPei/CpuDxe drivers in OvmfPkgX64 and IntelTdxX64. This
is done by setting different FILE_GUID to these drivers (of the same
name). In the other hand, we import a set of MpInitLibDepLib. These
libs simply depend on the PPI/Protocols. While these PPI/Protocols are
installed according to the guest type.

This patch-set is a replacement of
https://edk2.groups.io/g/devel/message/89381. Please see the dicussion in
 - https://edk2.groups.io/g/devel/message/89382
 - https://edk2.groups.io/g/devel/message/89455
 - https://edk2.groups.io/g/devel/message/89522
 - https://edk2.groups.io/g/devel/message/89535

The code is at: https://github.com/mxu9/edk2/tree/Rework-MpInitLib.v2

v2 changes:
 - Remove the un-used FILE_GUID definitions.
 - Delete un-used EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST in DispatchTable.
 - Add more comments.

So the idea is to pick the one or the other implementations via guid
and depex dependencies?  The approach looks sane to me.

Assuming the above is correct:
Acked-by: Gerd Hoffmann <kraxel@redhat.com>

take care,

Yes, it is the idea. In this way we can decouple the Tdx guest from MpInitLib (multi-processor version) in current stage.

Hi Min,

This appears to resolve the issue. I was able to boot a 64 vCPU guest in 
legacy, SEV, SEV-ES and SEV-SNP modes without any asserts.

I'm assuming that you were able to see the ASSERTs on your end and 
validate, too?

Thanks,
Tom

Yes. I enable a 4 vCPU legacy guest and can see the ASSERTs. But it appears in a random rate so it missed in the CI.

Hmmm... I hadn't noticed it before, but I'm seeing the following message
from the Linux kernel for each AP being brought online:

APIC: Stale IRR: 00000000,00000000,00000000,00000000,00000000,00000000,00000001,00000000 ISR: 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000000

Let me investigate this further to see where this regression was
introduced.

Thanks,
Tom

Yeah, with a low number of vCPUs, the crashes were random. When I upped 
the count to 64 vCPUs that could all run in parallel (running on an EPYC 
server box) it happened on (almost) every boot.

But glad that you were able to observe it and create this fix.

Thanks, Min!
