Subject: [PATCH v4 0/9] Add extra pci roots support for Arm
Date: Tue, 12 Jan 2021 17:45:40 +0800	[thread overview]
Message-ID: <20210112094549.10238-1-cenjiahui@huawei.com> (raw)

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.
