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 OVMF IA32 is a 32 bit only platform that no longer represents the vast majority of physical platforms.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/PciHostBridgeLib: remove Bhyve and Xen support

2021-06-04T16:01:50+00:00

The "OvmfPkg/Library/PciHostBridgeLib/PciHostBridgeLib.inf" instance is used by the following platforms in edk2: OvmfPkg/AmdSev/AmdSevX64.dsc OvmfPkg/OvmfPkgIa32.dsc OvmfPkg/OvmfPkgIa32X64.dsc OvmfPkg/OvmfPkgX64.dsc All these platforms statically inherit PcdPciDisableBusEnumeration=FALSE from "MdeModulePkg.dec". Remove the the PCD and everything that depends on it from the PciHostBridgeLib instance. Namely, remove the logic that determines the root bridge apertures by (a) scanning the entire bus, device and function number space, and (b) parsing the BAR values that were pre-set by the Bhyve or Xen machinery. "XenSupport.c" used to be listed explicitly in "Maintainers.txt", remove it from that spot too.

OvmfPkg/PciHostBridgeLib: consolidate #includes and INF file sections

2021-06-04T16:01:50+00:00

- In every C file, list every necessary public #include individually, with an example identifier that's actually consumed. - Place all public #includes first, all module-private #includes second. Separate them with a single empty line. Keep each section sorted in itself. - Sort all sections in the INF file, except [Defines]. - Add unlisted lib classes. - Remove unnecessary #include directives, add unlisted #include directives.
