          Assignee: dri-devel@lists.freedesktop.org
           Summary: [r600] Unreal Engine 4 demo crashed kernel
          Severity: major

kernel messages

Tried running Unreal Engine 4 demos from
https://wiki.unrealengine.com/Linux_Demos
'Mobile Temple Demo' started, worked bad (image was too dark, possible to see
almost nothing), but did not crash anything.
Next tried 'Effects Cave Demo': in a few seconds after first start of demo X
server became not responding (not even possible to switch with ctrl+alt+f1), it
was flickering between grey fill and normal desktop (seems kernel tried to
restart GPU), then system became fully unresponsive: ssh did not work, power
button did not send system to suspend. Attached kernel messages saved by
syslog.

I never had GPU related stability problems with 3.12.x-3.14.x kernels before:
several opengl 3d games worked fine, opengl based mpv video output worked fine,
glxgears and stellarium worked fine too.

Did unreal engine try to use some non implemented or unstable features? Why
kernel allowed to crash itself instead of killing userspace app?

Hardware: Radeon HD 6770
Software: Gentoo hardened amd64 stable, kernel-3.14.10, libdrm-2.4.54,
mesa-10.2.2, llvm-3.3, xf86-video-ati-7.3.0, xorg-server-1.15.0

I tried the Effects Cave Demo on a Radeon HD 6950: After it loaded the sound
played but the screen was going into standby and the system wasn't even
reacting to MagSysRq keys. Would love to give logs but they where wiped with
the system reset.

OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.3.0-devel

Now I tried Mobile Temple Demo, too, which played no sound and showed vertical
blue lines (garbage I guess) only till the watchdog kicked in.

--- Comment #5 from Knut Andre Tidemann <knut.tidemann@gmail.com> ---
I can also reproduce this with the effects demo on this card:
[AMD/ATI] Redwood XT [Radeon HD 5670/5690/5730]

I was able to ssh into the machine and kill the application, which restored the
display on the X server.

The following output was seen repeating in the terminal output of the
application:

EE r600_shader.c:157 r600_pipe_shader_create - translation from TGSI failed !
EE r600_state_common.c:751 r600_shader_select - Failed to build shader variant
(type=1) -1

as well as GPU lockups in the kernel like this:

I have no problems running any demo from that site.

However - there is some severe and very annoying stuttering. Which I can also
replicate on games using that engine...
Can someone else confirm?

Yes, it's because of shader recompiles. This is being addressed and will
hopefully be fixed before too long. It's not related to this bug report though.

Thanks for the info. By adressed you mean in the engine or in the driver?
Also is there a bug report about this / can I track this somewhere?
