Needs two little tweaks in PCI code because microvm supports mmio only. Other than that just wire up the existing code (the PCIe host adapter used by microvm is the same (virtual) hardware used by the arm/aarch64 virtual machines).
v7: - allow non-existing io address space only in case there are no io reservations (Mateusz Albecki) v6: - codestyle fix (Abner Chang). v5: - codestyle (uncrustify) fix. v4: - update PciHostBridge check (Abner Chang). v3: - rebase to latest master, adapt to PlatformInitLib. - rework PhysMemAddressWidth handling for microvm. v2: - rebase to latest master - pick up review tags Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=3777 Gerd Hoffmann (6): MdeModulePkg/PciHostBridge: io range is not mandatory OvmfPkg/FdtPciHostBridgeLib: io range is not mandatory OvmfPkg/Platform: unfix PcdPciExpressBaseAddress OvmfPkg/Microvm/pcie: no vbeshim please OvmfPkg/Microvm/pcie: mPhysMemAddressWidth tweak OvmfPkg/Microvm/pcie: add pcie support OvmfPkg/Microvm/MicrovmX64.dsc | 40 ++++++++++------- .../PlatformInitLib/PlatformInitLib.inf | 4 +- OvmfPkg/PlatformPei/PlatformPei.inf | 2 +- .../Bus/Pci/PciHostBridgeDxe/PciHostBridge.c | 6 +++ .../FdtPciHostBridgeLib/FdtPciHostBridgeLib.c | 45 ++++++++++--------- OvmfPkg/Library/PlatformInitLib/MemDetect.c | 45 ++++++++++++++++++- OvmfPkg/Library/PlatformInitLib/Platform.c | 4 +- OvmfPkg/PlatformPei/Platform.c | 2 +- OvmfPkg/QemuVideoDxe/VbeShim.c | 2 + OvmfPkg/Microvm/README | 2 +- 10 files changed, 107 insertions(+), 45 deletions(-) -- 2.36.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
