similar to: [PATCH 0/4] drm/nouveau: Replace {un/reference} with {put, get} functions

This patch set replaces the occurrences of drm_*_reference() and drm_*_unreference() with the new drm_*_get() and drm_*_put() functions. All patches in the series do the same thing, converting to the new APIs. I created patches per DRM driver as suggested by Daniel Vetter. Background: In the kernel, reference counting APIs use *_get(), *_put() style naming to reference-count the objects. But DRM

All fields in struct nouveau_framebuffer appear to be obsolete. The data structure can be replaced by struct drm_framebuffer entirely. Patch 1 removes several unused fields from struct nouveau_framebuffer. Patch 2 moves the field vma to struct nouveau_fbdev. The information in vma is only relevant for fbdev emulation, and as such he field is only used there. Patch 3 removes nvbo from struct

Because all drivers currently use gem objects for framebuffer planes, the virtual create_handle() is not required. This change adds a struct drm_gem_object *gems[4] field to drm_framebuffer and removes create_handle() function pointer from drm_framebuffer_funcs. The corresponding *_create_handle() function is removed from each driver. In many cases this change eliminates a struct *_framebuffer

This patch unifies the naming of DRM functions for reference counting of struct drm_gem_object. The resulting code is more aligned with the rest of the Linux kernel interfaces.

Note I'm adding some fields to nouveau_framebuffer in the series "drm/nouveau: Support NVIDIA format modifiers." I sent out v3 of that yesterday. It would probably still be possible to avoid them by re-extracting the relevant data from the format modifier on the fly when needed, but it is simpler and likely less error-prone with the wrapper struct.

Yes, that's certainly viable. If that's the general preference in direction, I'll rework that patches to do so.

The format modifiers, when present, override the equivalent field in the BO. Right now, that's probably not particularly useful. However, as nouveau interfaces evolve towards the HW capabilities and add support for newer graphics APIs, saying an entire BO has a singular layout becomes less meaningful, so I suspect those fields will be effectively deprecated in favor of the

Hi, Generally the the imported buffers which has memory type TTM_PL_TT are mapped as small pages probably due to lack of big page allocation. But the platform device which also use memory type TTM_PL_TT, like GK20A, can *allocate* big page though the IOMMU hardware inside the SoC. This is a try to map the imported buffers as big pages in GMMU by the platform IOMMU. With some preparation work to
