drm/todo: Tick off some tinydrm entries
- Better manual-upload support for atomic The new damage helper has the necessary pieces to make this work. - tinydrm_gem_cma_prime_import_sg_table This is now moved to the CMA helper and can be set using the DRM_GEM_CMA_VMAP_DRIVER_OPS macro. - tinydrm_fb_create This is now covered by drm_gem_fb_create_with_dirty() Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190115043643.2364-6-noralf@tronnes.org

-Better manual-upload support for atomic
----------------------------------------
-
-This would be especially useful for tinydrm:
-
-- Add a struct drm_rect dirty_clip to drm_crtc_state. When duplicating the
- crtc state, clear that to the max values, x/y = 0 and w/h = MAX_INT, in
- __drm_atomic_helper_crtc_duplicate_state().
-
-- Move tinydrm_merge_clips into drm_framebuffer.c, dropping the tinydrm\_
- prefix ofc and using drm_fb\_. drm_framebuffer.c makes sense since this
- is a function useful to implement the fb->dirty function.
-
-- Create a new drm_fb_dirty function which does essentially what e.g.
- mipi_dbi_fb_dirty does. You can use e.g. drm_atomic_helper_update_plane as the
- template. But instead of doing a simple full-screen plane update, this new
- helper also sets crtc_state->dirty_clip to the right coordinates. And of
- course it needs to check whether the fb is actually active (and maybe where),
- so there's some book-keeping involved. There's also some good fun involved in
- scaling things appropriately. For that case we might simply give up and
- declare the entire area covered by the plane as dirty.

Fallout from atomic KMS
-----------------------
@@ -459,21 +435,10 @@ those drivers as simple as possible, so lots of room for refactoring:
one of the ideas for having a shared dsi/dbi helper, abstracting away the
transport details more.
-- tinydrm_gem_cma_prime_import_sg_table should probably go into the cma
- helpers, as a _vmapped variant (since not every driver needs the vmap).
- And tinydrm_gem_cma_free_object could the be merged into
- drm_gem_cma_free_object().
-
-- tinydrm_fb_create we could move into drm_simple_pipe, only need to add
- the fb_create hook to drm_simple_pipe_funcs, which would again simplify a
- bunch of things (since it gives you a one-stop vfunc for simple drivers).
-
- Quick aside: The unregister devm stuff is kinda getting the lifetimes of
a drm_device wrong. Doesn't matter, since everyone else gets it wrong
too :-)
-- also rework the drm_framebuffer_funcs->dirty hook wire-up, see above.
