drm/nouveau: drop drm/ prefix from include

2016-05-13T13:06:10Z

Similar to the rest of the DRM UAPI - these are to be imported unmodified into libdrm. In current form that's impossible. Signed-off-by: Emil Velikov Acked-by: Ben Skeggs

nouveau_drm.h: use u32 and u64 from linux/types.h

2015-12-10T11:33:23Z

Fixes userspace compilation errors like: drm/nouveau_drm.h:41:2: error: unknown type name ‘uint32_t’ Signed-off-by: Mikko Rapeli

drm/nouveau: remove unnecessary usage of object handles

2015-11-03T05:02:18Z

No longer required in a lot of cases, as objects are identified over NVIF via an alternate mechanism since the rework. Signed-off-by: Ben Skeggs

drm/nouveau/gem: allow user-space to specify an object should be coherent

2015-04-14T07:00:46Z

User-space use mappable BOs notably for fences, and expects that a value update by the GPU will be immediatly visible through the user-space mapping. ARM has a property that may prevent this from happening though: memory can be mapped multiple times only if the different mappings share the same caching properties. However all the lowmem memory is already identity-mapped into the kernel with cache enabled, so when user-space requests an uncached mapping, we actually get an "undefined caching policy" one and this has strange side-effects described on Freedesktop bug 86690. To prevent this from happening, allow user-space to explicitly specify which objects should be coherent, and create such objects with the TTM_PL_FLAG_UNCACHED flag. This will make TTM allocate memory using the DMA API, which will fix the identify mapping and allow us to safely map the objects to user-space uncached.
