| | | | | | | | | | | | | | | | | Also swap the ordering of 32bit PCI MMIO window on q35, i.e. use the room between end of low memory and the start of the mmconfig bar. With a typical configuration on modern qemu with gigabyte-aligned memory the MMIO window start at 0x8000000, sized 1532 MB. In case there is memory present above 0x80000000 the window will start at 0xc0000000 instead, with 512 MB size. This depends on qemu commit 4a4418369d6d ("q35: fix mmconfig and PCI0._CRS"), so it raises the bar for the lowest supported version to qemu 4.1 (released Aug 2019).

* OvmfPkg/OvmfPkg*.dsc: Increase ACPI Reclaim memory sizeannie li2022-09-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | The current ACPI Reclaim memory size is set as 0x10 (64KiB). The ACPI table size will be increased if the memory slots' number of the guest gets increased. In the guest with more memory slots, the ACPI Reclaim memory size may not be sufficient for hibernation. This may cause resume failure of the hibernated guest that was booted up with a fresh copied writable OVMF_VARS file. However, the failure doesn't happen in following hibernation/resume cycles. The ACPI_MAX_RAM_SLOTS is set as 256 in the current QEMU. With ACPI_MAX_RAM_SLOTS, 18 pages are required to be allocated in ACPI Reclaim memory. However, due to the 0x10 (16 pages) setting, 2 extra pages will be allocated in other space. This may break the hibernation/resume in the above scenario. This patch increases the ACPI Reclaim memory size to 0x12, i.e. PcdMemoryTypeEfiACPIReclaimMemory is set as 0x12 (18 pages).

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3835 The commit ade62c18f4742301bbef474ac10518bde5972fba caused a boot failure when OVMF is build with SECURE_BOOT/SMM enabled. This happen because the above commit extended the BaseMemEncryptSevLib.inf to include VmgExitLib. The FvbServicesSmm uses the functions provided by the MemEncryptSevLib to clear the memory encryption mask from the page table. It created a dependency, as shown below OvmfPkg/FvbServicesSmm.inf ---> MemEncryptSevLib class ---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf" instance ---> VmgExitLib ---> "OvmfPkg/VmgExitLib" instance ---> LocalApicLib class ---> UefiCpuPkg/BaseXApicX2ApicLib/BaseXApicX2ApicLib.inf instance ---> TimerLib class ---> "OvmfPkg/AcpiTimerLib/DxeAcpiTimerLib.inf" instance ---> PciLib class ---> "OvmfPkg/DxePciLibI440FxQ35/DxePciLibI440FxQ35.inf" instance The LocalApicLib provides a constructor, execution of the constructor causes an exception. The SEV-ES and SEV-SNP do not support the SMM, so skip including the VmgExitLib chain. Use the module override to use the VmgExitLibNull to avoid the inclusion of unneeded LocalApicLib dependency chain in FvbServicesSmm. We ran similar issue for AmdSevDxe driver, see commit 19914edc5a0202cc7830f819ffac7e7b2368166a After the patch, the dependency look like this: OvmfPkg/FvbServicesSmm.inf ---> MemEncryptSevLib class ---> "OvmfPkg/BaseMemEncryptSevLib/DxeMemEncryptSevLib.inf" instance ---> VmgExitLib ---> "UefiCpuPkg/Library/VmgExitLibNull" instance Fixes: ade62c18f4742301bbef474ac10518bde5972fba Reported-by: Aaron Young <aaron.young@oracle.com> Cc: Dann Frazier <dann.frazier@canonical.com> Cc: Michael Roth <michael.roth@amd.com> Cc: James Bottomley <jejb@linux.ibm.com> Cc: Min Xu <min.m.xu@intel.com> Cc: Jiewen Yao <jiewen.yao@intel.com> Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Ard Biesheuvel <ardb+tianocore@kernel.org> Cc: Erdem Aktas <erdemaktas@google.com> Cc: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Tested-by: dann frazier <dann.frazier@canonical.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/MemEncryptSevLib: add support to validate system RAMBrijesh Singh via groups.io2021-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3275 Many of the integrity guarantees of SEV-SNP are enforced through the Reverse Map Table (RMP). Each RMP entry contains the GPA at which a particular page of DRAM should be mapped. The guest can request the hypervisor to add pages in the RMP table via the Page State Change VMGEXIT defined in the GHCB specification section 2.5.1 and 4.1.6. Inside each RMP entry is a Validated flag; this flag is automatically cleared to 0 by the CPU hardware when a new RMP entry is created for a guest. Each VM page can be either validated or invalidated, as indicated by the Validated flag in the RMP entry. Memory access to a private page that is not validated generates a #VC. A VM can use the PVALIDATE instruction to validate the private page before using it. During the guest creation, the boot ROM memory is pre-validated by the AMD-SEV firmware. The MemEncryptSevSnpValidateSystemRam() can be called during the SEC and PEI phase to validate the detected system RAM. One of the fields in the Page State Change NAE is the RMP page size. The page size input parameter indicates that either a 4KB or 2MB page should be used while adding the RMP entry. During the validation, when possible, the MemEncryptSevSnpValidateSystemRam() will use the 2MB entry. A hypervisor backing the memory may choose to use the different page size in the RMP entry. In those cases, the PVALIDATE instruction should return SIZEMISMATCH. If a SIZEMISMATCH is detected, then validate all 512-pages constituting a 2MB region. Upon completion, the PVALIDATE instruction sets the rFLAGS.CF to 0 if instruction changed the RMP entry and to 1 if the instruction did not change the RMP entry. The rFlags.CF will be 1 only when a memory region is already validated. We should not double validate a memory as it could lead to a security compromise. If double validation is detected, terminate the boot.
