There is one last fix going in there today as a result of the vendor (Aspeed) doing intensive testing. The sha1's are still changing. I will be sending the new series to Dave Airlie for upstreaming today and will update this bug when that is done.

Additional info: This series isn't POWER specific. It will fix issues with any server using aspeed BMC graphics.

Hi Canonical,

We would like to have the follow patches included in Ubuntu, to improve AST device driver. One of the POWER9 machines has an AST card, and these patches are useful to have it working properly:

a455ad6395 drm/ast: Call open_key before enable_mmio in POST code
f12175646d drm/ast: Fix test for VGA enabled
cebd35bdf4 drm/ast: POST code for the new AST2500
0062e661b9 drm/ast: Rename ast_init_dram_2300 to ast_post_chip_2300
4bab68a8d5 drm/ast: Factor mmc_test code in POST code
23810df5b7 drm/ast: Fixed vram size incorrect issue on POWER
ed29ff3019 drm/ast: Base support for AST2500
f5defee34f drm/ast: Fix calculation of MCLK
20d1eff177 drm/ast: Remove spurrious include
a5fb120633 drm/ast: const'ify mode setting tables
95d34f1481 drm/ast: Handle configuration without P2A bridge

Patches will be upstream soon but are currently the top 11 patches here https://github.com/ozbenh/linux-ast/commits/master

There is one last fix going in there today as a result of the vendor (Aspeed) doing intensive testing. The sha1's are still changing. I will be sending the new series to Dave Airlie for upstreaming today and will update this bug when that is done.
Series sent. Patches can be found here:

https://github.com/ozbenh/linux-ast/commits/master

Additional info: This series isn't POWER specific. It will fix issues with any server using aspeed BMC graphics.

Is the fix a new patch or a change to the existing patches? The patches I've applied are the same ones currently in benh's github tree, so if it's a new patch I can just apply it once it's available.

This bug was fixed in the package linux - 4.10.0-11.13
