kernel: 4.5.2 mesa: 11.3.0_devel.81287.59156b2 when playing victor vran dmesg gets spammed with MISALIGNED_GPR and MULTIPLE_WARP_ERRORS, the game runs and i cant notice any particular side effects from it, i have apitraced it and found the bad glDrawElementsInstancedBaseVertex call. karolherbst didnt get it when replaying the trace which is why we suspected its a gk110+ issue. the call happends in frame 228 and call 372955 according to qapitrace. trace is a bit big, 372mb compressed. trace: https://www.dropbox.com/s/lxrt0oneqaz4mvb/victorvran.tar.xz?dl=1 dmesg: https://gist.github.com/gulafaran/012338e3c3d07c34e289957cb934f5ed GL_FRAGMENT_SHADER from qapitrace: https://gist.github.com/gulafaran/2dfa0998770e3b35468013df07216e71 GL_VERTEX_SHADER from qapitrace: https://gist.github.com/gulafaran/cb51eae8ba9bdb79ed59ca8988266e39
Should be fixed by: commit 2ef3cdb07e42d985103b5a3e930b2bba676e920b Author: Ilia Mirkin <imirkin@alum.mit.edu> Date: Sat May 14 19:25:15 2016 -0400 nvc0/ir: make sure to align the second arg of TXD to 4, as we do for TEX This was handled in handleTEX(), however the way the logic works, those extra arguments aren't added on by then, so it did nothing. Instead we must duplicate that bit here. GK110 appears to complain about MISALIGNED_GPR, however it's reasonable to believe that GK104 has the same requirements.
