[edk2-devel] [PATCH v4 0/9] Add extra pci roots support for Arm

Posted by Jiahui Cen via groups.io 1 week, 6 days ago
v3->v4:
* Refactor InitRootBridges/UninitRootBridges/GetRootBridges/FreeRootBridges.
* Fix library dependencies.

v2->v3:
* Rename utility functions under the PciHostBridgeUtilityLib namespace.
* Remove some unused Library dependencies.
* Sort the Include headers.

v1->v2:
* Separated into four patches.
* Factor the same logic parts into a new library.

v3: https://edk2.groups.io/g/devel/message/69382
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3059
QEMU: https://lore.kernel.org/qemu-devel/20201119014841.7298-1-cenjiahui@huawei.com/

This patch series adds support for extra pci roots for ARM.

In order to avoid duplicated codes, we introduce a new library
PciHostBridgeUtilityLib which extracts common interfaces from
OvmfPkg/PciHostBridgeLib. It provides conflicts informing and extra pci
roots scanning. Using the utility lib, the uefi could scan for extra
root buses and recognize multiple roots for ARM.

I'm looking forward to v6; I'd really like to merge that, so I can move
on to reviewing other patches.

Thanks!
