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). ________________________________________ From: amd-gfx <amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx> on behalf of Tom St Denis <tom.stdenis at amd.com> Sent: Monday, September 18, 2017 13:33 To: amd-gfx at lists.freedesktop.org Cc: dri-devel at lists.freedesktop.org Subject: remove ttm trace and add iova debugfs (v2) In this respin I add some changes per feedback and make the iova entry have proper read/write methods which access pages mapped by amdgpu. 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 at lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx
