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 OVMF IA32 is a 32 bit only platform that no longer represents the vast majority of physical platforms.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/PciHostBridgeLibScan: clean up file names and file-top comments

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

Rename "XenSupport.c" to "ScanForRootBridges.c", after the main function in it. Update the file-top comments; refer to both Bhyve and Xen.

OvmfPkg/PciHostBridgeLibScan: remove PcdOvmfHostBridgePciDevId

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

The "OvmfPkg/Library/PciHostBridgeLibScan/PciHostBridgeLibScan.inf" instance is used in the following platforms in edk2: OvmfPkg/Bhyve/BhyveX64.dsc OvmfPkg/OvmfXen.dsc Neither Bhyve nor Xen provide a Q35 board, therefore the expression PcdGet16 (PcdOvmfHostBridgePciDevId) != INTEL_Q35_MCH_DEVICE_ID always evaluates to TRUE, in the PciHostBridgeLibScan instance. Replace the expression with constant TRUE, eliminating the PCD dependency. (In effect, this reports that the root bridge being registered does not support extended PCI config space.)

OvmfPkg/PciHostBridgeLibScan: remove QEMU (fw_cfg) support

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

The "OvmfPkg/Library/PciHostBridgeLibScan/PciHostBridgeLibScan.inf" instance is used in the following platforms in edk2: OvmfPkg/Bhyve/BhyveX64.dsc OvmfPkg/OvmfXen.dsc Both platforms define "PcdPciDisableBusEnumeration" with Fixed-at-Build access method, and TRUE value. Remove the PCD from the PciHostBridgeLibScan instance, and everything else that is useful only when the PCD is FALSE. In practice, this removes the PciHostBridgeUtilityGetRootBridges() function call, which is based on fw-cfg; see "OvmfPkg/Library/PciHostBridgeUtilityLib/PciHostBridgeUtilityLib.c". (Note that the dependency on PciHostBridgeUtilityLib remains in place, given that the PciHostBridgeLibScan instance continues using lower-level functions from the library that do not depend on fw-cfg.)

OvmfPkg/PciHostBridgeLibScan: create from PciHostBridgeLib

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

Create an almost verbatim copy of the "OvmfPkg/Library/PciHostBridgeLib/PciHostBridgeLib.inf" library instance. The new PciHostBridgeLibScan instance will ultimately duplicate a negligible amount of code from the original, and will be used by the Bhyve and OvmfXen platforms. List the new driver in "Maintainers.txt", in the "OvmfPkg: bhyve-related modules" and "OvmfPkg: Xen-related modules" sections. This patch should be reviewed with "git show --find-copies-harder".
