* OvmfPkg: exclude NullMemoryTestDxe driverLaszlo Ersek2023-12-072-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NullMemoryTestDxe was included in the OVMF platforms in historical commit 999a815e9ff3 ("OvmfPkg: Add NullMemoryTestDxe driver", 2011-01-21). It produces gEfiGenericMemTestProtocolGuid. With LegacyBiosDxe gone, the only consumer of this protocol in all of edk2 is "EmulatorPkg/Library/PlatformBmLib/PlatformBmMemoryTest.c". Thus, exclude NullMemoryTestDxe from all OVMF platforms. (Notably, ArmVirtPkg platforms don't include NullMemoryTestDxe either.)

* MdeModulePkg: Duplicate BaseRngLibTimerLib to MdeModulePkgPierre Gondois2023-09-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504 The BaseRngLibTimerLib allows to generate number based on a timer. This mechanism allows to have a basic non-secure implementation for non-production platforms. To bind and identify Random Number Generators implementations with a GUID, an unsafe GUID should be added. This GUID cannot be added to the MdePkg unless it is also added to a specification. To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to the MdeModulePkg. This will allow to define an unsafe Rng GUID in a later patch in the MdeModulePkg. The MdePkg implementation will be removed later. This allows to give some time to platform owners to switch to the MdeModulePkg implementation.

* Ovmf/HardwareInfoLib: Add Dxe lib to dynamically parse heterogenous dataNicolas Ojeda Leon2022-06-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Ovmf/HardwareInfoLib: Create Pei lib to parse directly from fw-cfgNicolas Ojeda Leon2022-06-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* OvmfPkg: Update IoMmuDxe to support TDXMin Xu2022-04-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429 The IOMMU protocol driver provides capabilities to set a DMA access attribute and methods to allocate, free, map and unmap the DMA memory for the PCI Bus devices. The current IoMmuDxe driver supports DMA operations inside SEV guest. To support DMA operation in TDX guest, CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr) is used to determine if it is SEV guest or TDX guest. Due to security reasons all DMA operations inside the SEV/TDX guest must be performed on shared pages. The IOMMU protocol driver for the SEV/TDX guest uses a bounce buffer to map guest DMA buffer to shared pages in order to provide the support for DMA operations inside SEV/TDX guest. The call of SEV or TDX specific function to set/clear EncMask/SharedBit is determined by CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr).

* OvmfPkg: Update Sec to support TdxMin Xu2022-04-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Create initial version of PlatformInitLibMin Xu2022-04-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3863 There are 3 variants of PlatformPei in OvmfPkg: - OvmfPkg/PlatformPei - OvmfPkg/XenPlatformPei - OvmfPkg/Bhyve/PlatformPei/PlatformPei.inf These PlatformPeis can share many common codes, such as Cmos / Hob / Memory / Platform related functions. This commit (and its following several patches) are to create a PlatformInitLib which wraps the common code called in above PlatformPeis. In this initial version of PlatformInitLib, below Cmos related functions are introduced: - PlatformCmosRead8 - PlatformCmosWrite8 - PlatformDebugDumpCmos They correspond to the functions in OvmfPkg/PlatformPei: - CmosRead8 - CmosWrite8 - DebugDumpCmos Considering this PlatformInitLib will be used in SEC phase, global variables and dynamic PCDs are avoided. We use PlatformInfoHob to exchange information between functions. EFI_HOB_PLATFORM_INFO is the data struct which contains the platform information, such as HostBridgeDevId, BootMode, S3Supported, SmmSmramRequire, etc. After PlatformInitLib is created, OvmfPkg/PlatformPei is refactored with this library.

* OvmfPkg: add PcdVideoResolutionSourceGerd Hoffmann2022-01-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
