Bisected to: fb0e9b5197cb65bde1e116d89acd5deb32f9132c Author: Jason Ekstrand <jason.ekstrand@intel.com> i965: Track the depth and render caches separately More tests in this group were (itermittently) failing again today on BDW & BSW, so I have disabled this group of tests from running on those two platforms: dEQP-GLES31.functional.copy_image.non_compressed.viewclass_32_bits. *** Bug 104570 has been marked as a duplicate of this bug. *** Does this series help? https://patchwork.freedesktop.org/series/35325/ Created attachment 137233 [details] [review] workaround I debugged this and noticed that flushing always for genX(blorp_exec) makes tests pass. Maybe this helps? Jason, let me know if there are some particular things I could check. I'm beginning to think that the root cause here is actually a hardware bug. I'm trying to get a hold of someone who better understands GEN cache hierarchies to know for sure. dEQP-GLES31.functional.copy_image.mixed tests were also failing intermittently in CI on these 4 platforms. Jason, I thought I saw a patch to work around this land, is that correct? Hacked around with commit 8379bff6c4456f8a77041eee225dcd44e5e00a76 Author: Jason Ekstrand <jason.ekstrand@intel.com> Date: Fri Mar 9 21:23:23 2018 -0800 i965: Emit texture cache invalidates around blorp_copy So dropping from the 18.0 blockers list. Leaving open as we'll need a real solution eventually. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
