https://bugzilla.kernel.org/show_bug.cgi?id=198883 --- Comment #67 from Ricardo Ribalda (ricardo.ribalda@xxxxxxxxx) --- I have coreboot. So I do not have the typical menu. I have an FPGA writing to the main memory, and that could not happen if iommu is enabled without extra configuration. If you can tell me which register to look for we can be 100% sure. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
