OvmfPkg: Remove OVMF IA32

2025-09-09T18:49:32+00:00

This commit removes OVMF IA32 from edk2 per RFC https://edk2.groups.io/g/devel/topic/rfc_remove_ovmf_ia32_and/114152215. OVMF IA32 is a 32 bit only platform that no longer represents the vast majority of physical platforms. The RFC details more reasoning in much more depth. OVMF IA32 will be kept in a branch off the edk2-stable202508 tag for any long term consumers; it will receive build break updates only (e.g. if an upstream submodule changes location).

OvmfPkg/OvmfXen: Introduce Xen's ResetSystemLib, to use xen hypercall

2024-08-30T16:55:41+00:00

When booting OvmfXen, the ACPI interface for shutdown/reset might not be available, instead use the hypercall interface. While it's probably possible to use the hypercall in all cases, we keep using the same interface while it still possible. That is ACPI on HVM guest, and fallback to hypercall on PVH guest.

OvmfPkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout OvmfPkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel Reviewed-by: Sunil V L

OvmfPkg/ResetSystemLib: introduce the DxeResetSystemLib instance

2020-04-22T19:42:32+00:00

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: rename to BaseResetSystemLib

2020-04-22T19:42:32+00:00

In preparation for introducing DxeResetSystemLib, rename the current (only) ResetSystemLib instance to BaseResetSystemLib. In the DSC files, keep the ResetSystemLib resolution in the same [LibraryClasses] section, but move it near the TimerLib resolution, as the differences between the ResetSystemLib instances will mostly follow those seen under OvmfPkg/Library/AcpiTimerLib. (While OvmfXen does not use "OvmfPkg/Library/AcpiTimerLib", perform the same movement there too, for keeping future DSC diffing simple.)
