Hi, So tiling work is i believe done. I have run piglit accross wide range of hw and sw combination. Bottom line is new mesa on top of either old kernel or old ddx won't regress anything. New mesa on top of proper kernel will get you 2D tiling for texture and anything allocated by mesa, and if you have proper DDX with option ColorTiling2D enabled you will also get 2D tiling for front buffer and depth/stencil buffer.
For libdrm you need the lastest master. I will do a libdrm release on monday. Afterward i will commit mesa & ddx with proper autoconf voodoo to check for the new libdrm. kernel patches : http://people.freedesktop.org/~glisse/tiling/0001-drm-radeon-kms-add-support-for-streamout-v7.patch http://people.freedesktop.org/~glisse/tiling/0001-drm-radeon-add-support-for-evergreen-ni-tiling-infor.patch mesa patch: http://people.freedesktop.org/~glisse/tiling/0001-r600g-add-support-for-common-surface-allocator-for-t.patch ddx patch: http://people.freedesktop.org/~glisse/tiling/0001-r600-evergreen-use-common-surface-allocator-for-tili.patch Link to piglit test: http://people.freedesktop.org/~glisse/tiling/cayman/changes.html http://people.freedesktop.org/~glisse/tiling/cedar/changes.html http://people.freedesktop.org/~glisse/tiling/redwood/changes.html http://people.freedesktop.org/~glisse/tiling/juniper/changes.html http://people.freedesktop.org/~glisse/tiling/fusion/changes.html http://people.freedesktop.org/~glisse/tiling/rv770/changes.html http://people.freedesktop.org/~glisse/tiling/rv710/changes.html http://people.freedesktop.org/~glisse/tiling/rv635/changes.html http://people.freedesktop.org/~glisse/tiling/rv610/changes.html first column GPU name is unpatched mesa,unpatched ddx,unpatched kernel second column surf0-ddx0 is patched mesa,patched ddx with 2d tiling disabled and new mesa code path disabled (basicly check that nothing regress in old code path). third column patched mesa, unpatched ddx using new mesa code path. This check that mesa on top of old userspace doesn't break anything. fourth column patched mesa, patched ddx, unpatched kernel. This check that new mesa on top of old kernel works properly. fith column is everything is patched and 2D tiling is enabled everywhere. Note that few test just randomly switch from pass to fail (fbo-sys-blit*, read-front, ...). I also tested a lot the old userspace on top of new kernel for evergreen to make sure that the command checker doesn't regress anything. While it reject some command stream thus were wrong and never successfully completed. Leading to no regression in piglit (basicly second column). Fusion doesn't have unpatched kernel run as things keep locking up for me with unpatched kernel.
