Created attachment 89950 [details] dmesg System Environment: -------------------------- Platform: Broadwell kernel (drm-intel-nexe-queued)8b4f49e03901e82898540bd1189333edf9588d74 Some additional commit info: Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Mon Nov 25 15:51:16 2013 -0800 drm/i915: split fb allocation and initialization v2 If we use a stolen buffer, our probe callback shouldn't allocate a new buffer; we should re-use the one from the BIOS instead if possible. v2: fix locking (Jesse) Bug detailed description: ----------------------------- Igt/gem_render_copy causes gpu hangs. This is the first time to run igt test on Broadwell. Error log: [ 186.649624] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 186.649715] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [ 186.652134] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [ 186.654378] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [ 186.656653] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. Steps: --------------------------- ./gem_render_copy
Again, please attach the gpu hang. Also I think Damien is working on patches for the rendercpy code, so assigning to him for now.
It'd be interesting to try again with the instruction lengths fixed (intel-gpu-tools as of today). But IIUC what Ben was suggesting, we may have something not quite right in the kernel.

gem_render_copy testing for gen8_render_copy func blocks many other testcases, so rise its priority.
I have disabled rendercopy for now to help QA with their runs. Hangs are annoying.
I think it'll be easier to wait for the mesa guys to figure out what's wrong and copy what they do. It could be a null state missing, a magic bit not set in one of the commands. I guess it could also be a missing W/A at this point, we might want to do a pass on them.
Closing as not a bug until we have working rendercopy. Please reopen if there is still an issue when we do.
