No, I tried to add assert : diff --git a/src/gallium/drivers/nouveau/nv50/nv50_query.c b/src/gallium/drivers/nouveau/nv50/nv50_query.c index a373dc6..23f5eaf 100644 --- a/src/gallium/drivers/nouveau/nv50/nv50_query.c +++ b/src/gallium/drivers/nouveau/nv50/nv50_query.c @@ -222,6 +222,7 @@ nv50_query_end(struct pipe_context *pipe, struct pipe_query *pq) break; case PIPE_QUERY_GPU_FINISHED: q->sequence++; + assert(0); nv50_query_get(push, q, 0, 0x1000f010); break; case NVA0_QUERY_STREAM_OUTPUT_BUFFER_OFFSET: on top of mesa-git-454aab4 and it doesn't trigger during mplayer's run (resulted in usual hang).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
