https://bugzilla.kernel.org/show_bug.cgi?id=196409 --- Comment #34 from Nick Sarnie (commendsarnex@xxxxxxxxx) --- Hi all, Just a quick update. A workaround has been found. Please see the following post: https://lists.linuxfoundation.org/pipermail/iommu/2017-October/024823.html Please note that this patch is only a workaround, is incorrect in some cases and cannot be merged upstream in this form. But, it's a start and you can make this change locally to workaround the GPU performance hit. Thanks, Sarnex -- You are receiving this mail because: You are watching the assignee of the bug.
