--- Comment #4 from Johannes Hirte (johannes.hi...@datenkhaos.de) --- (In reply to Michel Dänzer from comment #3) > Looks like https://bugs.freedesktop.org/109234 => > https://lists.freedesktop.org/archives/dri-devel/2019-January/202909.html > and follow-ups. Yes, looks like it's this bug. From https://lists.linuxfoundation.org/pipermail/iommu/2019-January/032651.html > Hmm, I wonder if we are not actually using swiotlb in the end, > can you check if your dmesg contains this line or not? > > PCI-DMA: Using software bounce buffering for IO (SWIOTLB) No, it isn't. I can't find anything about SWIOTLB or PCI-DMA in dmesg. Just testing the patch. I don't have a reproducer, but it could be suspend/resume related. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
