[Intel-gfx] [PATCH 00/24] drm_framebuffer boilerplate removal

[Daniel Stone]

Hi,
I've been working on a getfb2[0] ioctl, which amongst other things
supports multi-planar framebuffers as well as modifiers. getfb
currently calls the framebuffer's handle_create hook, which doesn't
support multiple planes.

Thanks to Noralf's recent work, drivers can just store GEM objects
directly in drm_framebuffer. I use this directly in getfb2: we need
direct access to the GEM objects and not a vfunc in order to not hand
out duplicate GEM names for the same object.

This series converts all drivers except for nouveau, which was a
little too non-trivial for my comfort, to storing GEM objects directly
in drm_framebuffer. For those drivers whose driver_framebuffer struct
was nothing but drm_framebuffer + BO, it deletes the driver-specific
struct. It also makes use of Noralf's generic framebuffer helpers for
create_handle and destroy where possible.

I don't have the hardware for most of these drivers, so have had to
settle for just staring really hard at the diff.

I intend to remove create_handle when all drivers are converted over
to placing BOs directly inside drm_framebuffer. For most drivers
there's a relatively easy conversion to using the helpers for
basically all framebuffer handling and fbdev emulation as well, though
that's a bit further than I was willing to go without hardware to test
on ...

Cheers,
Daniel
