My colleague Denis bisected it to: commit 5ad0c88dbe3e5805a10d8f1fef9d0cf1bbecdd46 (HEAD, refs/bisect/bad) Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> Date: Tue Mar 12 14:51:22 2019 -0700 iris: Replace buffer backing storage and rebind to update addresses. ....... 2. At the moment I found out that INTEL_DEBUG=sync fixes the issue as well as the following patch: diff --git a/src/gallium/drivers/iris/iris_resource.c b/src/gallium/drivers/iris/iris_resource.c index 989c112a3e3..b076c09af83 100644 --- a/src/gallium/drivers/iris/iris_resource.c +++ b/src/gallium/drivers/iris/iris_resource.c @@ -1175,7 +1175,7 @@ iris_invalidate_resource(struct pipe_context *ctx, return; // XXX: We should support this. - if (res->bind_history & PIPE_BIND_STREAM_OUTPUT) + if (res->bind_history & (PIPE_BIND_STREAM_OUTPUT | PIPE_BIND_SAMPLER_VIEW)) return; struct iris_bo *old_bo = res->bo; So according to the patch, I can assume that something went wrong with sampler_views but at the moment, I can't say what exactly so I continue my investigation.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
