[PATCH 0/4] drm/nouveau: Remove struct nouveau_framebuffer
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

[PATCH 4/4] drm/nouveau: Remove struct nouveau_framebuffer
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. Thanks, -James On 2/6/20

[PATCH 4/4] drm/nouveau: Remove struct nouveau_framebuffer
Yes, that's certainly viable. If that's the general preference in direction, I'll rework that patches to do so.

[PATCH 4/4] drm/nouveau: Remove struct nouveau_framebuffer
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
