2018-05-25drm/atmel-hlcdc: Stop using plane->fbVille Syrjälä1-11/+1
We want to get rid of plane->fb on atomic drivers. Stop looking at it. Daniel pointed out that the drm_framebuffer_put() in the plane cleanup indicates that the driver doesn't shut things down cleanly. To do that we should be able to just call drm_atomic_helper_shutdown().

Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up through the atomic API, but realizing that userspace is likely to take shortcuts and assume that the enum values are what is sent over the wire. As a result these defines are provided purely as a convenience to userspace applications.

2017-02-28drm/atmel-hlcdc: Simplify the HLCDC layer logicBoris Brezillon1-332/+313
An HLCDC layers in Atmel's nomenclature is either a DRM plane or a 'Post Processing Layer' which can be used to output the results of the HLCDC composition in a memory buffer. atmel_hlcdc_layer.c was designed to be generic enough to be re-usable in both cases, but we're not exposing the post-processing layer yet, and even if we were, I'm not sure the code would provide the necessary tools to manipulate this kind of layer. Moreover, the code in atmel_hlcdc_{plane,layer}.c was designed before the atomic modesetting API, and was trying solve the check-setting/commit-if-ok/rollback-otherwise problem, which is now entirely solved by the existing core infrastructure. And finally, the code in atmel_hlcdc_layer.c is over-complicated compared to what we really need. This rework is a good excuse to simplify it. Note that this rework solves an existing resource leak (leading to a -EBUSY error) which I failed to clearly identify.

2017-02-26drm: Always prepare null framebuffer in transitional helperGabriel Krisman Bertazi1-0/+3
Despite the documentation claim that cleanup_fb will match prior calls to prepare_fb, in case of NULL framebuffers in the transitional helpers, the code will skip the call to prepare_fb but not the corresponding cleanup_fb call. This asymmetry in semantics is unnecessarily surprising for developers transitioning drivers to atomic model, specially because the final atomic handlers don't have the issue - the prepare_fb is always called, despite the new state framebuffer being null. The only current user of the transitional helper that doesn't take care of null framebuffers explicitly inside the prepare_fb hook is atmel_hlcdc, so we take special care to make sure we don't break anything there.

2015-12-11drm: Pass 'name' to drm_universal_plane_init()Ville Syrjälä1-1/+1
Done with coccinelle for the most part. It choked on msm/mdp/mdp5/mdp5_plane.c like so: "BAD:!!!!! enum drm_plane_type type;" No idea how to deal with that, so I just fixed that up by hand. Also it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards. I didn't convert drm_plane_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ typedef uint32_t; identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5, E6, E7; @@ drm_universal_plane_init(E1, E2, E3, E4, E5, E6, E7 + ,NULL ) v2: Split crtc and plane changes apart Pass NUL for no-name instead of "" Leave drm_plane_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670795-2853-1-git-send-email-ville.syrjala@linux.intel.com

2015-09-08drm/atomic: Make prepare_fb/cleanup_fb only take state, v3.Maarten Lankhorst1-1/+3
This removes the need to separately track fb changes i915. That will be done as a separate commit, however. Changes since v1: - Add dri-devel to cc. - Fix a check in intel's prepare and cleanup fb to take rotation into account. Changes since v2: - Split out i915 changes to a separate commit.

2015-03-05drm: Pass in new and old plane state to prepare_fb and cleanup_fbTvrtko Ursulin1-1/+2
Use cases like rotation require these hooks to have some context so they know how to prepare and cleanup the frame buffer correctly. For i915 specifically, object backing pages need to be mapped differently for different rotation modes and the driver needs to know which mapping to instantiate and which to tear down when transitioning between them. v2: Made passed in states const.

2015-02-22drm: atmel-hlcdc: add discard area supportBoris Brezillon1-0/+108
The HLCDC IP provides a way to discard a specific area on the primary plane (in case at least one of the overlay is activated and alpha blending is disabled). Doing this will reduce the amount of data to transfer from the main memory to the Display Controller, and thus alleviate the load on the memory bus (since this link is quite limited on such hardware, this kind of optimization is really important).

2015-01-21drm: add Atmel HLCDC Display Controller supportBoris Brezillon1-0/+856
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.
