The actual output of the program is: GL_VERSION: 3.3 (Core Profile) Mesa 11.1.2 ASSERT: Scalar FS validation failed! load_payload(8) vgrf2:UD, (null):UD(null):UD(null):UD, vgrf0+3.0:F brw_fs_validate.cpp:53: inst->src[i].reg_offset + inst->regs_read(i) <= (int)alloc.sizes[inst->src[i].nr] Aborted (core dumped) This seems to have been fixed for a while. I tracked the fix down to this commit: commit 7f53fead5cf9a85c74a94d359dd5fccfbb87856c Author: Timothy Arceri <timothy.arceri@collabora.com> Date: Mon May 23 16:48:05 2016 +1000 i965: enable component packing for vs and fs Rather than trying to work out the total number of components used at a location we simply treat all outputs as vec4s. This removes the need for complex code looping over varyings to match packed locations and the need for storing the total number of components used at each location.

Has that commit actually made it into a release yet?
(In reply to org.freedesktop from comment #7) > Has that commit actually made it into a release yet? It's in mesa-13.0.0 which was just released yesterday. :) Ah, thanks. I was going to say that I'd wait for my distro to catch up, but it seems like they just pushed new 13.0.0 packages out today. |
