Should add I was able to read/write system memory mapped by amdgpu with these patches in place on my polaris10 device (with iommu enabled of course).

So there is no need for /dev/mem or /dev/fmem anymore when reading system memory. Patches 3/4 are unchanged and remove the TTM trace from amdgpu and from TTM itself. _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx _______________________________________________ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
