Created attachment 130455 [details] INTEL_DEBUG=wm output deferredmultisampling: compiler/brw_fs_generator.cpp:2107: int fs_generator::generate_code(const cfg_t*, int): Assertion `validated' failed. There are "ERROR: src0 is null" messages when run with INTEL_DEBUG=wm. If I comment the assert out, the demo runs seemingly correctly (matches radv at least), and I see no problems reported by validation layers. HW: SKL GT2 Mesa git version: 641f629536c2da
Thanks for the report! I've got a patch to fix this on the mailing list.
This has been fixed by the following commit in master: commit 3503b2714b98684a2ceba5f4fd9a5bfbfbcaad38 Author: Jason Ekstrand <jason.ekstrand@intel.com> Date: Wed Mar 29 15:16:15 2017 -0700 i965/fs: Always provide a default LOD of 0 for TXS and TXL We already provide a default LOD for textureQueryLevels and texture() on non-fragment stages. However, there are more cases where one is needed such as textureSize(gsampler2DMS*) in SPIR-V. Instead of trying to list out all of the cases one at a time, just provide the default for all TXS and TXL operations. This fixes a shader validation error in the new Sascha deferredmultisampling demo which uses textureSize(gsampler2DMS).
