[edk2-devel] [PATCH v6 0/4] AMD processor MSR_IA32_MISC_ENABLE
Posted by Kirkendall, Garrett 4 years, 5 months ago 
AMD processor does not support MSR_IA32_MISC_ENABLE register.  Accessing
this register on AMD causes an unhandled exception in SmmEntry.nasm and
a subsequent failure to boot since this is too early in SMM path for the
exception handler to be loaded.

1. Prepare PcAtChipsetPkg/PcAtChipsetPkg.dsc to move
StandardSignatureIsAuthenticAMD into UefiCpuLib LibraryClass
BaseUefiCpuLib in UefiCpuPkg.

2. To distinguish between AMD and other processors, refactor
StandardSignatureIsAuthenticAMD into BaseUefiCpuLib.  So there is only
one copy in the source.

3. Skip manipulation of MSR_IA32_MISC_ENABLE register if running
on an AMD processor.

Tested on AMD X64 hardware.
OvmfIa32 and OvmfIa32X64 on Intel hardware.

v1: Move StandardSignatureIsAuthenticAMD. Handle MSR_IA32_MISC_ENABLE
v2: Incorporate Laszlo's feedback
v3: Typo, not sent
v4: Patch in to add UefiCpuLib to PcAtChipsetPkg.dsc
v5: Patch in to add UefiCpuLib to SourceLevelDebugPkg.dsc
v6: Hopefully reformat patch when sending????

I think we still have an open question here:

  https://edk2.groups.io/g/devel/message/61583

To clarify: I'm not suggesting that we should fix that issue. I'm saying
that we should *understand* Guomin's report enough so we can decide
*whether* this series needs a further update, or not.

If there is no feedback (clarification) from Guomin in a few days, I
think Eric or Ray (the UefiCpuPkg maintainers) should merge v6 -- for
example, on Friday.

Thanks,
Laszlo

Re: [edk2-devel] [PATCH v6 0/4] AMD processor MSR_IA32_MISC_ENABLE
Posted by Dong, Eric 4 years, 4 months ago 
Hi Laszlo,

I have fixed the issue reported by Guomin in below change.

SHA-1: 0060e0a694f3f249c3ec081b0e61287c36f64ebb

* IntelFsp2Pkg/FspSecCore: Use UefiCpuLib.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2825

UefiCpuLib has API InitializeFloatingPointUnits.
Remove internal copy of InitializeFloatingPointUnits
in FspSecCoreM, use UefiCpuLib API.

This change also avoid later potential conflict when
use UefiCpuLib for FspSecCoreM module.

With <https://bugzilla.tianocore.org/show_bug.cgi?id=2825> fixed (commit
0060e0a694f3), this patch set should be merged now.

I was about to do just that, but the review status of the series is
still incomplete. Even though this patch series has been on the list for
two weeks now.

- Ray, can you please review patch#1 immediately?

- Hao, can you please review patch#2 immediately?

- Ray and Eric, can one of you please review patch #4 at once?

Thanks
Laszlo
