I was on irc a few days ago trying to get the new amdgpu driver up and running on my system. I am able to get the kernel booted successfully, however X via amdgpu is turning out to be a real roadblock. It is the problem with amdgpu_drv.so seeing gbm_create_device as an undefined symbol. From what little I understand, I may be needing a more recent xserver to resolve this...

I don't think that would help.

Does the attached xf86-video-amdgpu patch fix the problem?

If not, you can manually load the glamoregl module in /etc/X11/xorg.conf to pull in libgbm:

Section "Module" Load "glamoregl" EndSection

Hi Michel, thanks for the reply. I got around to recompiling the stack from the latest trees as noted by Alex earlier. However, I'm afraid something may have changed recently and I may be needing a newer xserver after all. Loading amdgpu_drv.so now results in:

[ 1122.347] (EE) module ABI major version (19) doesn't match the server's version (18)

That just means the driver it's trying to load wasn't built against the same version of xserver. Make sure the xf86-video-amdgpu build is picking up the xorg-server.pc and header files of the same version of xserver you're trying to run.

Oops! Looks like I forgot to cc the mailing list.

I think my version mismatch issues above may have been resolved by a recent upload of xserver-xorg-core 2:1.17.1-2 to debian unstable(?)...

As a result, I could finally test Michel's patch, and I am happy to say that X via amdgpu is now working for me! Thanks to Michel! :)

However, the two additional issues mentioned in my initial post are still present:

*) Non-working DVI-I-0 -- even if I use xrandr to turn it off and on again, a signal is never acquired.

*) System lockup on xen boot (even magic sysrq is not recognized)
