Hi Fred,
The artful repository is git://kernel.ubuntu.com/ubuntu/ubuntu-
artful.git
It contains 4417ec7a7c8d ("UBUNTU: SAUCE: PCI: Support hibmc VGA cards
behind a misbehaving HiSilicon bridge")
This was an earlier version of those patches and should allow xorg
autoconfiguration to work.
Regards,
Daniel

hibmc driver does not include "pci:" prefix in bus ID

Bug description:
SRU Justification
[Impact]
On the HiSilicon D05 (arm64) board, X crashes when started. [0]
[Fix]
The crash is attributable to the bus ID that the hibmc driver reports for the
hibmc graphics card on the board. In particular, the bus id is missing the
"pci:" prefix that most other cards provide: [1]
- The busid reported on the arm64 system is "0007:a1:00.0"
- The busid reported on a amd64 system is "pci:0000:00:02.0"
X tests for this prefix. A missing prefix for PCI cards leads to an
Xorg crash.
Fix this by using the set_pci_busid function from the DRM core.
[Testcase]
Successfully tested on a D05 board. [2]
[Regression Potential]
Changes are limited to the hibmc driver, so any regression should also be
limited to that driver.
[Notes]
I submitted the patch upstream. However, upstream is refactoring the drm
core, and set_busid is going away. That does fix this issue but the regression
potential of the refactor is enormous, so this seems like the wiser approach.
