2019-09-11drm/nouveau: switch to gem vma offset managerGerd Hoffmann1-1/+1
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.

2019-09-11drm/ttm: turn ttm_bo_device.vma_manager into a pointerGerd Hoffmann1-0/+1
Rename the embedded struct vma_offset_manager, new name is _vma_manager. ttm_bo_device.vma_manager changed to a pointer. The ttm_bo_device_init() function gets an additional vma_manager argument which allows to initialize ttm with a different vma manager. When passing NULL the embedded _vma_manager is used. All callers are updated to pass NULL, so the behavior doesn't change.

2019-03-19drm/ttm: Quick-test mmap offset in ttm_bo_mmap()Thomas Zimmermann1-3/+0
A BO's address has to be at least the minimum offset. Sharing this test in ttm_bo_mmap() removes code from drivers.

This will cause a subtle behaviour change on GPUs that are in mixed-memory configurations in that VRAM in the degraded section of VRAM will no longer be used for TTM buffer objects. That section of VRAM is not meant to be used for displayable/compressed surfaces, and we have no reliable way with the current interfaces to be able to make that decision properly.

2015-04-14make RAM device optionalAlexandre Courbot1-0/+3
Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the longer term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in places where a RAM device was assumed to be present and allows some more objects to be allocated from the TT domain, allowing Nouveau to handle GPUs for which pfb->ram == NULL.

2015-01-22drm/nouveau: finalise nvkm namespace switch (no binary change)Ben Skeggs1-26/+26
The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
