Ovmf/HardwareInfoLib: Create Pei lib to parse directly from fw-cfg Define the HardwareInfoLib API and create the PeiHardwareInfoLib which implements it, specifically for Pei usage, supporting only static accesses to parse data directly from a fw-cfg file. All list-like APIs are implemented as unsupported and only a fw-cfg wrapper to read hardware info elements is provided. The Hardware Info library is intended to describe non-discoverable hardware information and share that from the host to the guest in Ovmf platforms. The QEMU fw-cfg extension for this library provides a first variation to parse hardware info by reading it directly from a fw-cfg file. This library offers a wrapper function to the plain QmeuFwCfgReadBytes which, specifically, parses header-data pairs out of the binary values in the file. For this purpose, the approach is incremental, reading the file block by block and outputting the values only for a specific known hardware type (e.g. PCI host bridges). One element is returned in each call until the end of the file is reached. Considering fw-cfg as the first means to transport hardware info from the host to the guest, this wrapping library offers the possibility to statically, and in steps, read a specific type of hardware info elements out of the file. This method reads one hardware element of a specific type at a time, without the need to pre-allocate memory and read the whole file or dynamically allocate memory for each new element found. As a usage example, the static approach followed by this library enables early UEFI stages to use and read hardware information supplied by the host. For instance, in early times of the PEI stage, hardware information can be parsed out from a fw-cfg file prescinding from memory services, that may not yet be available, and avoiding dynamic memory allocations.

Ovmf/HardwareInfoLib: Add Dxe lib to dynamically parse heterogenous data Following the Hardware Info library, create the DxeHardwareInfoLib which implements the whole API capable of parsing heterogeneous hardware information. The list-like API grants callers a flexible and common pattern to retrieve the data. Moreover, the initial source is a BLOB which generalizes the host-to-guest transmission mechanism. The Hardware Info library main objective is to provide a way to describe non-discoverable hardware so that the host can share the available resources with the guest in Ovmf platforms. This change features and embraces the main idea behind the library by providing an API that parses a BLOB into a linked list to retrieve hardware data from any source. Additionally, list-like APIs are provided so that the hardware info list can be traversed conveniently. Similarly, the capability is provided to filter results by specific hardware types. However, heterogeneous elements can be added to the list, increasing the flexibility. This way, a single source, for example a fw-cfg file, can be used to describe several instances of multiple types of hardware. This part of the Hardware Info library makes use of dynamic memory and is intended for stages in which memory services are available. A motivation example is the PciHostBridgeLib. This library, part of the PCI driver populates the list of PCI root bridges during DXE stage for future steps to discover the resources under them. The hardware info library can be used to obtain the detailed description of available host bridges, for instance in the form of a fw-cfg file, and parse that information into a dynmaic list that allows, first to verify consistency of the data, and second discover the resources availabe for each root bridge.

OvmfPkg: Update Sec to support Tdx RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 There are below major changes in this commit. 1. SecEntry.nasm In TDX BSP and APs goes to the same entry point in SecEntry.nasm. BSP initialize the temporary stack and then jumps to SecMain, just as legacy Ovmf does. APs spin in a modified mailbox loop using initial mailbox structure. Its structure defition is in OvmfPkg/Include/IndustryStandard/IntelTdx.h. APs wait for command to see if the command is for me. If so execute the command. 2. Sec/SecMain.c When host VMM create the Td guest, the system memory informations are stored in TdHob, which is a memory region described in Tdx metadata. The system memory region in TdHob should be accepted before it can be accessed. So the major task of this patch is to process the TdHobList to accept the memory. After that TDVF follow the standard OVMF flow and jump to PEI phase. PcdUse1GPageTable is set to FALSE by default in OvmfPkgX64.dsc. It gives no chance for Intel TDX to support 1G page table. To support 1G page table this PCD is set to TRUE in OvmfPkgX64.dsc. TDX_GUEST_SUPPORTED is defined in OvmfPkgX64.dsc. This macro wraps the Tdx specific code. TDX only works on X64, so the code is only valid in X64 arch.

OvmfPkg/ResetSystemLib: introduce the DxeResetSystemLib instance The BaseResetSystemLib instance is not suitable for OS runtime, because its ResetShutdown() implementation calls PciRead16 (OVMF_HOSTBRIDGE_DID). On q35, this boils down to a memory-mapped config space access -- but we never ask the OS to map MMCONFIG for runtime. There are at least three alternatives to approach this: (1) Investigate "MdePkg/Library/DxeRuntimePciExpressLib", which offers some kind of runtime mapping for MMCONFIG. (2) Consume PciCf8Lib directly, rather than PciLib, in ResetSystemLib. Then we'll read OVMF_HOSTBRIDGE_DID from the config space with IO port accesses on q35 too, not just on i440fx. IO ports don't depend on page tables. (3) In the lib constructor, cache "mAcpiPmBaseAddress" based on "PcdOvmfHostBridgePciDevId" (which is set by PlatformPei). Then the host bridge type will be known at runtime without PCI config space accesses. This patch follows approach (3), in order to mirror AcpiTimerLib. Notes: * This patch is best viewed with "git show --find-copies-harder -C43". * PCDs are not usable in the DXE_CORE, as the PCD PPI is gone, and the PCD protocol is not available yet. (The DXE_CORE does consume ResetSystemLib in practice, when OVMF is built with -D SOURCE_DEBUG_ENABLE.)

OvmfPkg/ResetSystemLib: introduce the DxeResetSystemLib instance The BaseResetSystemLib instance is not suitable for OS runtime, because its ResetShutdown() implementation calls PciRead16 (OVMF_HOSTBRIDGE_DID). On q35, this boils down to a memory-mapped config space access -- but we never ask the OS to map MMCONFIG for runtime. There are at least three alternatives to approach this: (1) Investigate "MdePkg/Library/DxeRuntimePciExpressLib", which offers some kind of runtime mapping for MMCONFIG. (2) Consume PciCf8Lib directly, rather than PciLib, in ResetSystemLib. Then we'll read OVMF_HOSTBRIDGE_DID from the config space with IO port accesses on q35 too, not just on i440fx. IO ports don't depend on page tables. (3) In the lib constructor, cache "mAcpiPmBaseAddress" based on "PcdOvmfHostBridgePciDevId" (which is set by PlatformPei). Then the host bridge type will be known at runtime without PCI config space accesses. This patch follows approach (3), in order to mirror AcpiTimerLib.

OvmfPkg: disable list length checks in NOOPT and DEBUG builds In NOOPT and DEBUG builds, if "PcdMaximumLinkedListLength" is nonzero, then several LIST_ENTRY *node* APIs in BaseLib compare the *full* list length against the PCD. This turns the time complexity of node-level APIs from constant to linear, and that of full-list manipulations from linear to quadratic. As an example, consider the EFI_SHELL_FILE_INFO list, which is a data structure that's widely used in the UEFI shell. I randomly extracted 5000 files from "/usr/include" on my laptop, spanning 1095 subdirectories out of 1538, and then ran "DIR -R" in the UEFI shell on this tree. These are the wall-clock times: PcdMaximumLinkedListLength PcdMaximumLinkedListLength =1,000,000 =0 -------------------------- --------------------------- FAT 4 min 31 s 18 s virtio-fs 5 min 13 s 1 min 33 s Checking list lengths against an arbitrary maximum (default: 1,000,000) seems useless even in NOOPT and DEBUG builds, while the cost is significant; so set the PCD to 0.

OvmfPkg/XenPlatformPei: Use CPUID to get physical address width on Xen We faced a problem with passing through a PCI device with 64GB BAR to UEFI guest. The BAR is expectedly programmed into 64-bit PCI aperture at 64G address which pushes physical address space to 37 bits. That is above 36-bit width that OVMF exposes currently to a guest without tweaking PcdPciMmio64Size knob. The reverse calculation using this knob was inhereted from QEMU-KVM platform code where it serves the purpose of finding max accessible physical address without necessary trusting emulated CPUID physbits value (that could be different from host physbits). On Xen we expect to use CPUID policy to level the data correctly to prevent situations with guest physbits > host physbits e.g. across migrations. The next aspect raising concern - resource consumption for DXE IPL page tables and time required to map the whole address space in case of using CPUID bits directly. That could be mitigated by enabling support for 1G pages in DXE IPL configuration. 1G pages are available on most CPUs produced in the last 10 years and those without don't have many phys bits. Remove all the redundant code now (including PcdPciMmio64.. handling that's not used on Xen anyway) and grab physbits directly from CPUID that should be what baremetal UEFI systems do.

OvmfPkg: add PcdVideoResolutionSource It's a UINT8 (enum) PCD telling where the PcdVideoHorizontalResolution and PcdVideoVerticalResolution values are coming from. It can be: 0 (unset aka default from dsc file), or 1 (from PlatformConfig), or 2 (set by Video Driver). It will be used by video drivers to avoid overriding PlatformConfig values, or override each others values in case multiple display devices are present. The underlying problem this tries to solve is that the GOP protocol has no way to indicate the preferred video mode. On physical hardware this isn't much of a problem because using the highest resolution available works just fine as that is typically the native display resolution But in a virtual machine you don't want come up with a huge 4k window by default just because the virtual vga is able to handle that. Cutting down the video mode list isn't a great solution either as that would also remove the modes from the platform configuration so the user wouldn't be able to pick a resolution higher than the default any more. So with patch drivers can use use PcdVideoHorizontalResolution and PcdVideoVerticalResolution to indicate what the preferred display resolution is, without overwriting the user preferences from PlatformConfig if present. A possible alternative approach would be to extend the GOP protocol, but I'm not sure this is a good plan given this is mostly a problem for virtual machines and using PCDs allows to keep this local to OvmfPkg.

OvmfPkg: unplug CsmSupportLib from BdsDxe 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).

OvmfPkg/AmdSevDxe: do not use extended PCI config space BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 Commit 85b8eac59b8c5bd9c7eb9afdb64357ce1aa2e803 added support to ensure that MMIO is only performed against the un-encrypted memory. If MMIO is performed against encrypted memory, a #GP is raised. The AmdSevDxe uses the functions provided by the MemEncryptSevLib to clear the memory encryption mask from the page table. If the MemEncryptSevLib is extended to include VmgExitLib then depedency chain will look like this: OvmfPkg/AmdSevDxe/AmdSevDxe.inf -----> MemEncryptSevLib class -----> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf" instance -----> VmgExitLib class -----> "OvmfPkg/VmgExitLib" instance -----> LocalApicLib class -----> "UefiCpuPkg/BaseXApicX2ApicLib/BaseXApicX2ApicLib.inf" instance -----> TimerLib class -----> "OvmfPkg/AcpiTimerLib/DxeAcpiTimerLib.inf" instance -----> PciLib class -----> "OvmfPkg/DxePciLibI440FxQ35/DxePciLibI440FxQ35.inf" instance -----> PciExpressLib class -----> "MdePkg/BasePciExpressLib/BasePciExpressLib.inf" instance The LocalApicLib provides a constructor that gets called before the AmdSevDxe can clear the memory encryption mask from the MMIO regions. When running under the Q35 machine type, the call chain looks like this: AcpiTimerLibConstructor () [AcpiTimerLib] PciRead32 () [DxePciLibI440FxQ35] PciExpressRead32 () [PciExpressLib] The PciExpressRead32 () reads the MMIO region. The MMIO regions are not yet mapped un-encrypted, so the check introduced in the commit 85b8eac59b8c5bd9c7eb9afdb64357ce1aa2e803 raises a #GP. The AmdSevDxe driver does not require the access to the extended PCI config space. Accessing a normal PCI config space, via IO port should be sufficent. Use the module-scope override to make the AmdSevDxe use the BasePciLib instead of BasePciExpressLib so that PciRead32 () uses the IO ports instead of the extended config space.
