Some graphics APIs differentiate between out-of-graphics-memory and out-of-host-memory (system memory). Add a device init flag to have -ENOSPC propagated from the resource managers instead of being converted to -ENOMEM, to aid driver stacks in determining what error code to return or whether corrective action can be taken at the driver level. The first patch deals with a ttm_device_init()

Pass gem vma_offset_manager to ttm_bo_device_init(), so ttm uses it instead of its own embedded struct. This makes some gem functions (specifically drm_gem_object_lookup) work on ttm objects.

Hi all, this little series removes the last swiotlb API exposed to modules.

Add max_segment argument to drm_prime_pages_to_sg(). When set pass it through to the __sg_alloc_table_from_pages() call, otherwise use SCATTERLIST_MAX_SEGMENT. Also add max_segment field to drm driver and pass it to drm_prime_pages_to_sg() calls in drivers and helpers. v2: place max_segment in drm driver not gem object.

Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer.

Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the

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
