2016-05-13	drm/nouveau: drop drm/ prefix from include	Emil Velikov	1	-1/+1
	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 <emil.l.velikov@gmail.com> Acked-by: Ben Skeggs <bskeggs@redhat.com>
2016-05-13	drm/nouveau: add extern C guard for the UAPI header	Emil Velikov	1	-0/+8

2015-12-10	nouveau_drm.h: use __u32 and __u64 from linux/types.h	Mikko Rapeli	1	-42/+44
	Fixes userspace compilation errors like: drm/nouveau_drm.h:41:2: error: unknown type name ‘uint32_t’ Signed-off-by: Mikko Rapeli <mikko.rapeli@iki.fi>
2015-11-03	drm/nouveau: remove unnecessary usage of object handles	Ben Skeggs	1	-8/+0
	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 <bskeggs@redhat.com>
2015-04-14	drm/nouveau/gem: allow user-space to specify an object should be coherent	Alexandre Courbot	1	-0/+1
	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.
