For this v2 I have fixed the patches that are non-controversial (all Lucas' :)) and am resubmitting them in the hope that they will get merged. This will just leave the issue of Nouveau system-memory buffers mapping to be solved. This issue is quite complex, so let me summarize the situation and the data I have at hand. ARM caching is like a quantum world where Murphy's law constantly

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Thomas Zimmermann (4): drm/vram: Move VRAM memory manager to GEM VRAM implementation drm/vram: Have VRAM MM call GEM VRAM functions directly drm/vram: Unexport internal functions of VRAM MM drm/vram: Unconditonally set BO call-back

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM

This small series introduces TTM helper functions as well as Nouveau hooks that are needed to ensure buffer coherency on ARM. Most of this series is a forward-port of some patches Lucas Stach sent last year and that are also needed for Nouveau GK20A support: http://lists.freedesktop.org/archives/nouveau/2013-August/014026.html Another patch takes care of flushing the CPU write-buffer when

Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same

Hi guys, Well let's face it AGP is a total headache to maintain and dead for at least 10+ years. We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc... So the idea here is to just go ahead and remove the support
