[PATCH v2 0/3] drm/ttm: nouveau: memory coherency for ARM
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

[PATCH 0/4] drm/ttm: nouveau: memory coherency fixes for ARM
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

[PATCH 0/6] Nouveau on ARM fixes
This is the first set of patches to make Nouveau work on Tegra. Those are only the obvious correctness fixes, a lot of optimization work remains to be done, but at least it's enough to get accel working and let the machine survive a piglit run. A new BO flag is introduced to allow userspace to hint the kernel about possible optimizations. Lucas Stach (6): drm/ttm: recognize ARM arch in

[PATCH v4 05/10] drm/ttm: Add vmap/vunmap to TTM and TTM GEM helpers
The new functions ttm_bo_{vmap,vunmap}() map and unmap a TTM BO in kernel address space. The mapping's address is returned as struct dma_buf_map. Each function is a simplified version of TTM's existing kmap code. Both functions respect the memory's location ani/or writecombine flags. On top TTM's functions, GEM TTM helpers got drm_gem_ttm_{vmap,vunmap}(), two helpers that convert

[PATCH 2/2] drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_global
So far, struct ttm_bo_global_ref was the only way of initializing a struct ttm_bo_global. Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO. The original functions for initializing and releasing via struct ttm_bo_global_ref are wrappers

[patch V3 31/37] drm/ttm: Replace kmap_atomic() usage
There is no reason to disable pagefaults and preemption as a side effect of kmap_atomic_prot(). Use kmap_local_page_prot() instead and document the reasoning for the mapping usage with the given pgprot. Remove the NULL pointer check for the map. These functions return a valid address for valid pages and the return was bogus anyway as it would have left preemption and pagefaults disabled.
