Ok, so I think part of the problem is that the kernel hibmc driver needs to use a set_busid function from the drm core. I've simulated this change in the debugger, and it seems to at least prevent the crash. (It doesn't seem to be enough for the server to work, still working on that.)
Here's a patch - we can discuss the best way to build and install it. ** Patch added: "0001-Use-standard-busid-function-from-drm-core.patch" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1691991/+attachment/4887275/+files/0001-Use-standard-busid-function-from-drm-core.patch -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1691991 Title: Xorg Segmentation fault on Hisilicon D05 board (arm64) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1691991/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
