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. BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4584 **Changes from V1 to V2:** 1. Add Ray's Ack signature to patch 13. 2. Add LoongArchVirt's self introduction-file. And made a standalone patch for this change. **Changes from V2 to V3:** Compared with V2, there are 9 more patches, removed 2 libraries and 1 driver from OvmfPkg/LoongArchVrt. New patches: MdePkg: Add a new library named PeiServicesTablePointerLibReg MdePkg: Add method of LoongArch64 to PeiServicesTablePointerLibReg MdePkg: Add a PCD feature flag named PcdPciIoTranslationIsEnabled UefiCpuPkg: Add MMIO method in CpuIo2Dxe ArmVirtPkg: Enable UefiCpuPkg version CpuIo2Dxe ArmPkg: Remove ArmPciCpuIo2Dxe from ArmPkg OvmfPkg/RiscVVirt: Enable UefiCpuPkg version CpuIo2Dxe OvmfPkg/RiscVVirt: Remove PciCpuIo2Dxe from RiscVVirt ArmVirtPkg: Move the FdtSerialPortAddressLib to OvmfPkg ArmVirtPkg: Move the PcdTerminalTypeGuidBuffer into OvmfPkg ArmVirtPkg: Move PlatformBootManagerLib to 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.
