This patch set will enable LoongArch virtual machine in edk2, the new
LoongArch virtual machine is located in OvmfPkg/LoongArchVirt/, it is a
generic platform that dose not require any actual hardware.
Patch1-Patch14: Submit the common library and driver for LoongArch
virtual machine and real hardware. Such as base help functions,
exception handel, MMU library, multiprocessor library etc.
Patch15-Patch16: Add PrePiCpuIoSize for LoongArch64. and move ArmVirtPkg
two PCDs into OvmfPkg for easier use by other architectures.
Patch17-Patch29: LoongArch virtual machine private code, include SEC and
PEI phase code, some library and drivers.
Patch30: Add LoongArchVirt's self introduction-file.
Modfied modues: MdePkg, UefiCpuPkg, EmbeddedPkg, ArmVirtPkg, OvmfPkg.

For the review opinions:
1. Add MMIO method to CpuIo2Dxe driver to accommodate more ARCH that
require MMIO method, enable it on ARM, RISCV64 and LOONGARCH64.
Questioner: Gerd, Sunil.
2. Move the FdtSerialProtAddressLib to OvmfPkg and enabled it on ARM and
LOONGARCH64. Questioner: Gerd, Laszlo.
3. Add a new library in MdePkg named PeiServiceTablePointerLibReg for
the Register Mechanism and enabled it on LOONGARCH64. Questioner: Laszlo.
4. Moved the ARM version of PlatformBootManagerLib to OvmfPkg/Library, and
enabled it on ARM and LOONGARCH64. Questioner: Laszlo, Gerd.
5. Adjust the order of some inf file in ArmVirtPkg. Questioner: Sami.
6. Move the CpuMmuLib.h some architecture-specific PTE #defines into
Csr.h. Questioner: Andrei.
**Changes from V3 to V4:**
Compared with V3, 1 patch moving ArmPciCpuIo2Dxe has been removed.
Adjusted the code of the LoongArch64 CPU timer library. Rename
PeiServiceTablePointerLibReg to PeiServiceTablePointerLibKs0. Fixed some
typos. Remove some APIs of CpuMmuLib.
For the review opinions:
1. Removed the patch that removed ArmPciCpuIo2Dxe, there are 15 platforms
in edk2-platforms were affected, so wait for this patch series to be
merged, then submit a patch to remove it. Questioner: Leif.
2. Renamed the PeiServiceTablePointLibReg to PeiServiceTablePointLibKs0.
Currently, this library is specific to LoongArch architecture.
Questioner: Laszlo, Liming.
3. Adjust some logic of LoongArch64 CPU timer library. Using the safe
INT library and adjust the bit width of stable counter. Questioner: Laszlo.
4. Removed some APIs from CpuMmuLib. Change some APIs to private.
Questioner: Ray.
**Changes from V4 to V5:**
Compared with V4, 1 patch adding PcdPciIoTranslationIsEnabled in MdePkg
has been removed.
Copy ArmPciCpuIo2Dxe to UefiCpuPkg and renamed it to CpuMmio2Dxe.
Restore the definitions in MdePkg/Include/Protocol/DebugSupport.h, and
just add some comments.
For the review opinions:
1. Copy ArmPciCpuIo2Dxe to UefiCpuPkg so that more other ARCHs can use
it easily. Questioner: Ray, Ard.
2. Restore the changes of MdePkg/Include/Protocol/DebugSupport.h.
Questioner: Liming.
3. Ia32 X64 and LoongArch64 use a same API definition,
InitializeFloatingPointUnits in CpuLib.h. Questioner: Liming.
4. Adjust API definition in CpuMmuLib.h. Questioner: Ray.
**Changes from V5 to V6:**
1. Added Sunil "Reviewed-by" message to patches 20 and 21.
2. Added Bibo "Reviced-by" message to patches 27, 29, 32 and 34.
3. Added the IPI handler in SEC and PEI stage. Modified patches 11 and
15.
4. Adjust some code styles to suit CI ECC.
5. Adjust the way of AP wakeup from IPI.
6. Adjust the order between setting exceptions and copying exception
handlers.
**Changes from V6 to V7:**
Compared with V6, 1 patch has been added.
Added Bibo "Reviewed-by" message to new patches 26, 27, 29, 31, 32, 36,

Hi Ray and Laszlo,
Sorry, I was busy the past few days, so V8 was late.
Ray, I *removed* your review message in patches 11, 12, 24, 15 and 16,
because our adjusted the folders layout, so please review again, thanks.
Laszlo, I did what you pointed out, please refer the cover letter,
please review, thanks.
Thanks,
Chao

Hi Liming, Mike, Ray, Laszlo, Ard, Gerd Leif and Sunil,
Since there are some mixed voices regarding patches for UefiCpuPkg, and
the stable202402 feature deadline is approaching, so may I suggest that
splitting this series into two or more smaller series, and having
patches of don't depend on UefiCpuPkg merged into stable202402 first,
involving patches 1-10, 17- 25, other patches still need to be reviewed
and merged to master later. So what do you suggest?
Thanks,
Chao

This sounds good to me.
I think you should submit a new series that contains only the patches
that you mention above, also picking up any new review tags you've
received for v8. This will provide maintainers with a good overview.
(And this will be needed anyway for the actual PR.)
I think the only missing R-b has been for "[PATCH v8 20/37] ArmVirtPkg:
Enable CpuMmio2Dxe", but I have reviewed that patch now. So I believe
further patch-level reviews shouldn't be necessary, only an overview of
those selected patches organized into a dedicated series.
Regards,
Laszlo

Chao,
When I review the detailed changes, I found a generic issue:
Some changes to INF files are not necessary. They are just reordering the source files or libs within the same section.
I hope that you could avoid these unnecessary changes.
Another point is please make sure do not add unnecessary lib dependencies for x86 (e.g.: SafeIntLib). That might cause
some platform build breaks due to not including the SafeIntLib in DSC.
Thanks,
Ray

Subject: Re: [edk2-devel] [PATCH v8 00/37] Enable LoongArch virtual machine in edk2
Hi Liming, Mike, Ray, Laszlo, Ard, Gerd Leif and Sunil,
Since there are some mixed voices regarding patches for UefiCpuPkg, and the stable202402 feature deadline is approaching, so may I suggest that splitting this series into two or more smaller series, and having patches of don't depend on UefiCpuPkg merged into stable202402 first, involving patches 1-10, 17- 25, other patches still need to be reviewed and merged to master later. So what do you suggest?
Thanks,
Chao

Hi Ray and Laszlo,
Sorry, I was busy the past few days, so V8 was late.
Ray, I removed your review message in patches 11, 12, 24, 15 and 16, because our adjusted the folders layout, so please review again, thanks.
Laszlo, I did what you pointed out, please refer the cover letter, please review, thanks.

Restore the definitions in MdePkg/Include/Protocol/DebugSupport.h, and
just add some comments.
For the review opinions:
1. Copy ArmPciCpuIo2Dxe to UefiCpuPkg so that more other ARCHs can use
it easily. Questioner: Ray, Ard.
2. Restore the changes of MdePkg/Include/Protocol/DebugSupport.h.
Questioner: Liming.
3. Ia32 X64 and LoongArch64 use a same API definition,
InitializeFloatingPointUnits in CpuLib.h. Questioner: Liming.
4. Adjust API definition in CpuMmuLib.h. Questioner: Ray.
**Changes from V5 to V6:**
1. Added Sunil "Reviewed-by" message to patches 20 and 21.

37.
Added Liming "Reviewed-by" message to all MdePkg changes.
For the review opinions:
1. Moved the changes to OvmfPkg.dec from old patch 24 to new patch 23.
Questioner: Laszlo.
2. Separate the changes to DebugSupport.h from old patch 11 and
create a new patch 10. Questioner: Liming.
**Changes from V7 to V8:**
Adjusted the folders layout in UefiCpuPkg, most LoongArch64 libraries and
drivers have been placed in current matching folders.
Removed Ray "Reviewed-by" message to patches 11, 12, 14, 15, 16. Because
them are moved to other current matching folders in UefiCpuPkg, they
need to be reviewed again.

I'm myself a bit torn about this. I generally like to keep entries in
[LibraryClasses] etc lexicographically sorted. However, it indeed
becomes confusing when a lib class is added or removed *together* with
sorting the entire list afresh. I think such changes are worth splitting
in to: first, sort the entries (a no-op patch), then implement the change.

I wouldn't necessarily call them unnecessary. I think sorting / cleanups
are worthwhile, but they should be well separated from the other types
of changes.

Can you clarify?
SafeIntLib is generally a good idea to *use* in C code, and when one
uses it, it must be listed in [LibraryClasses]. I agree that, when we
extend an INF file with a new dependency, we should grep edk2 (at least)
for platform DSCs that refer to that INF, and see if we have to resolve
the lib class.
Of course, when the C code doesn't actually consume SafeIntLib APIs,
then listing SafeIntLib in the INF file is just a bug.
