2017-08-01drm: Plumb modifiers through plane initBen Widawsky2-1/+2
This is the plumbing for supporting fb modifiers on planes. Modifiers have already been introduced to some extent, but this series will extend this to allow querying modifiers per plane. Based on this, the client to enable optimal modifications for framebuffers. This patch simply allows the DRM drivers to initialize their list of supported modifiers upon initializing the plane. v2: A minor addition from Daniel v3: * Updated commit message * s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu) * Remove some excess newlines (Liviu) * Update comment for > 64 modifiers (Liviu) v4: Minor comment adjustments (Liviu) v5: Some new platforms added due to rebase v6: Add some missed plane inits (or maybe they're new - who knows at this point) (Daniel) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Daniel Stone <daniels@collabora.com> (v2) Reviewed-by: Liviu Dudau <Liviu.Dudau@arm.com> Signed-off-by: Daniel Stone <daniels@collabora.com>

Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages.

The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead.

2017-02-07drm: remove drm_vblank_no_hw_counter assignment from driver codeShawn Guo2-2/+0
Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi2-2/+2
Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

Hardware has multiple (2 or 3, depending on model) stride registers per layer; add a function that correctly takes that into account. On hardware that only has 2 stride registers, ensure that 3-plane (YUV) content has identical strides for both chroma planes.
