2024-01-15OvmfPkg: CloudHv: Enable PcdUse1GPageTableThomas Barrett1-0/+2
Without enabling PcdUse1GPageTable, CloudHv guests are limited to a 40-bit address space, even if the hardware supports more. This limits the amount of RAM to 1TiB of CloudHv guests. Signed-off-by: Thomas Barrett <tbarrett@crusoeenergy.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2024-01-15OvmfPkg: Update PlatformAddressWidthInitialization for CloudHvThomas Barrett1-0/+12
In addition to initializing the PhysMemAddressWidth and FirstNonAddress fields in PlatformInfoHob, the PlatformAddressWidthInitialization function is responsible for initializing the PcdPciMmio64Base and PcdPciMmio64Size fields. Currently, for CloudHv guests, the PcdPciMmio64Base is placed immediately after either the 4G boundary or the last RAM region, whichever is greater. We do not change this behavior. Previously, when booting CloudHv guests with greater than 1TiB of high memory, the PlatformAddressWidthInitialization function incorrect calculates the amount of RAM using the overflowed 24-bit CMOS register. Now, we update the PlatformAddressWidthInitialization behavior on CloudHv to scan the E820 entries to detect the amount of RAM. This allows CloudHv guests to boot with greater than 1TiB of RAM Signed-off-by: Thomas Barrett <tbarrett@crusoeenergy.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2024-01-15OvmfPkg: Add CloudHv support to PlatformScanE820 utility function.Thomas Barrett1-30/+65
The PlatformScanE820 utility function is not currently compatible with CloudHv since it relies on the prescence of the "etc/e820" QemuFwCfg file. Update the PlatformScanE820 to iterate through the PVH e820 entries when running on a CloudHv guest.

2023-12-08OvmfPkg/MemEncryptSevLib: Fix address overflow during PVALIDATEMichael Roth1-2/+3
The struct used for GHCB-based page-state change requests uses a 40-bit bit-field for the GFN, which is shifted by PAGE_SHIFT to generate a 64-bit address. However, anything beyond 40-bits simply gets shifted off when doing this, which will cause issues when dealing with 1TB+ addresses. Fix this by casting the 40-bit GFN values to 64-bit ones prior to shifting it by PAGE_SHIFT.

2023-12-07OvmfPkg: unplug CsmSupportLib from BdsDxeLaszlo Ersek5-16/+1
CsmSupportLib is effectively a hack. It produces the following protocols: - Legacy Bios Platform, - Legacy Interrupt, - Legacy Region2. (Note that the "OvmfPkg/Csm/CsmSupportLib/CsmSupportLib.inf" file contains an error where it claims that "Legacy Bios Platform" is "consumed" -- it is not; the lib instance produces that protocol). At the same time, the library instance consumes gEfiLegacyBiosProtocolGuid. This *seemingly* creates a circular dependency with LegacyBiosDxe, because that driver has the exact opposite protocol usage patterns. The solution is that LegacyBiosDxe has a DEPEX on the protocols produced by CsmSupportLib, while CsmSupportLib consumes the Legacy Bios Protocol from LegacyBiosDxe only in the member functions of the protocols it produces. Therefore, once BdsDxe is dispatched, and the CsmSupportLib constructor exposes those three protocols, LegacyBiosDxe can also be started by the DXE dispatcher, and then the protocols from CsmSupportLib become functional. But the main reason why CsmSupportLib is a hack is that it should be a normal platform DXE driver (called e.g. "CsmSupportDxe"), and not a NULL class library that's randomly hooked into BdsDxe. Given that we have removed LegacyBiosDxe earlier (so there is no DEPEX we need to satisfy now, conceptually), unhook CsmSupportLib from BdsDxe. --*-- Note that in the BhyveX64 platform, the pathname "OvmfPkg/Bhyve/Csm/CsmSupportLib/CsmSupportLib.inf" is bogus, and has always been, since commit 656419f922c0 ("Add BhyvePkg, to support the bhyve hypervisor", 2020-07-31).

2023-12-07OvmfPkg/IncompatiblePciDeviceSupportDxe: ignore CSM presenceLaszlo Ersek2-140/+6
The UEFI protocol database cannot contain gEfiLegacyBiosProtocolGuid any longer, after excluding LegacyBiosDxe from the OVMF platforms. Therefore, instruct PciBusDxe from IncompatiblePciDeviceSupportDxe to allocate 64-bit BARs above 4 GB regardless of a CSM. Regression test: in commit 855743f71774 ("OvmfPkg: prevent 64-bit MMIO BAR degradation if there is no CSM", 2016-05-25), where we introduced IncompatiblePciDeviceSupportDxe, we said, "By default, the PCI Bus driver considers an option ROM reason enough for allocating the 64-bit MMIO BARs in 32-bit address space". Therefore it suffices to verify the 64-bit BARs of a device for which QEMU provides an option ROM. The simplest case is the virtio-net-pci device. And indeed, with this patch applied, the log contains: > PciBus: Discovered PCI @ [04|00|00] [VID = 0x1AF4, DID = 0x1041] > BAR[1]: Type = Mem32; Alignment = 0xFFF; Length = 0x1000; Offset = 0x14 > BAR[4]: Type = PMem64; Alignment = 0x3FFF; Length = 0x4000; Offset = 0x20 This portion shows that Bus|Device|Function 04|00|00 is a (modern) virito-net-pci device [VID = 0x1AF4, DID = 0x1041]. > PciBus: Resource Map for Bridge [00|01|03] > Type = Mem32; Base = 0x81200000; Length = 0x200000; Alignment = 0x1FFFFF > Base = Padding; Length = 0x200000; Alignment = 0x1FFFFF > Base = 0x81200000; Length = 0x1000; Alignment = 0xFFF; Owner = PCI [04|00|00:14] > Type = Mem32; Base = 0x81A43000; Length = 0x1000; Alignment = 0xFFF > Type = PMem64; Base = 0x800200000; Length = 0x100000; Alignment = 0xFFFFF > Base = 0x800200000; Length = 0x4000; Alignment = 0x3FFF; Owner = PCI [04|00|00:20] This quote shows that 04|00|00 has a BAR at 0x8_0020_0000. (It also shows that the device is behind a bridge (PCIe root port) whose own BDF is 00|01|03.) > [Security] 3rd party image[7CEEB418] can be loaded after EndOfDxe: PciRoot(0x0)/Pci(0x1,0x3)/Pci(0x0,0x0)/Offset(0x10E00,0x273FF). > None of Tcg2Protocol/CcMeasurementProtocol is installed. > InstallProtocolInterface: [EfiLoadedImageProtocol] 7D2E5140 > Loading driver at 0x0007CA9F000 EntryPoint=0x0007CAA5447 1af41000.efi > InstallProtocolInterface: [EfiLoadedImageDevicePathProtocol] 7D5B2198 And this part finally shows that the iPXE option ROM for the device (1af41000.efi) was detected and is loaded.

2023-12-07OvmfPkg: exclude the CSM-based VideoDxe driverLaszlo Ersek12-45/+3
The CSM-based VideoDxe driver is a special UEFI_DRIVER module that both follows and doesn't follow the UEFI driver model. Namely, in the Supported and Start members of its Driver Binding Protocol instance, it consumes the Legacy Bios Protocol directly from the UEFI protocol database, as opposed to (only) opening protocols on the handle that it is supposed to bind. Furthermore, the driver "marks" its own image handle with the NULL-interface "Legacy Bios" (pseudo-protocol) GUID, in order to "inform back" the provider of the Legacy Bios Protocol, i.e., LegacyBiosDxe, that VideoDxe is a "BIOS Thunk Driver" in the system. Quoting "OvmfPkg/Csm/Include/Guid/LegacyBios.h", such a driver follows the UEFI Driver Model, but still uses the Int86() or FarCall() services of the Legacy Bios Protocol as the basis for the UEFI protocol it produces. In a sense, there is a circular dependency between VideoDxe and LegacyBiosDxe; each knows about the other. However, VideoDxe is a UEFI_DRIVER, while LegacyBiosDxe is a platform DXE_DRIVER with a very long DEPEX. Therefore, for keeping dependencies conceptually intact, first exclude VideoDxe from the OVMF platforms. Always include the hypervisor-specific real UEFI video driver. --*-- Note that the pathname "IntelFrameworkModulePkg/Csm/BiosThunk/VideoDxe/VideoDxe.inf" in the bhyve platform DSC and FDF files is bogus anyway.

2023-12-07OvmfPkg: cripple CSM_ENABLE macroLaszlo Ersek6-0/+6
We're going to gradually tear down and remove the Compatibility Support Module (CSM) in OvmfPkg (due to it having no maintainer). Start by making all platforms that have thus far accepted "-D CSM_ENABLE" reject that macro, so that mid-series, the partially removed infrastructure cannot be built or booted. Insert an !error directive in each DSC file's first "!ifdef $(CSM_ENABLE)" conditional. At the end of the series, the !error directive introduced in this patch will be removed.

2023-12-07OvmfPkg/Bhyve: use a proper PCI IO rangeCorvin Köhne1-2/+2
Bhyve uses an io port range of [ 0x2000, 0x10000 ] [1]. At the moment, EDKII is using a subset of this range [ 0xC000, 0x10000 ] [2]. Even though the EDKII range doesn't exceed the bhyve range, it's causing issues on some guests like OpenBSD [3]. We don't know why it's causing issues yet. However, using the same IO port range in EDKII fixes the issue and is a good idea anyway.

2023-11-28OvmfPkg/ResetVector: Define SNP metadata for kernel hashesDov Murik2-1/+21
In order to allow the VMM (such as QEMU) to add a page with hashes of kernel/initrd/cmdline for measured direct boot on SNP, add it explicitly to the SNP metadata list report to the VMM. In such case, VMM should fill the page with the hashes content, or explicitly update it as a zero page (if kernel hashes are not used). Note that for SNP, the launch secret part of the page (lower 3KB) are not relevant and will remain zero. The last 1KB is used for the hashes. This should have no effect on OvmfPkgX64 targets (which don't define PcdSevLaunchSecretBase).
