drm: Drop drm_blend.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_blend.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_blend.h. Quite a few placs do currently depend on drm_blend.h without actually including it directly. All of those need to be fixed up.

drm/sun4i: Constify static structs

2020-08-18T08:49:13+00:00

A number of static variables are not modified and can be made const to allow the compiler to put them in read-only memory. Signed-off-by: Rikard Falkeborn Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20200804215337.54594-1-rikard.falkeborn@gmail.com

drm/sun4i: drop use of drmP.h

2019-07-17T10:52:45+00:00

Drop use of the deprecated drmP.h header file. While touching the list of include file, use the typical order of the blocks: \#include \#include \#include \#include "" Within each block, sort the files. Include necessary files to fix build after the drmP.h removal.

drm/sun4i: Use drm_fbdev_generic_setup()

2018-11-01T14:25:11+00:00

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.

drm/sun4i: backend: Add support for zpos

2018-01-29T13:02:40+00:00

Our various planes have a configurable zpos, that combined with the pipes allow to configure the composition. Since the interaction between the pipes, zpos and alphas framebuffers is not trivial, let's just enable the zpos as an immutable property for now, and use that zpos in our atomic_update part.

drm/sun4i: framebuffer: Add a custom atomic_check

2018-01-29T13:02:36+00:00

In order to support normalized zpos, we need to call drm_atomic_normalize_zpos in our driver's drm_mode_config_funcs' atomic_check. Let's duplicate the definition of drm_atomic_helper_check for now.

drm/sun4i: backend: Use runtime_pm variant of atomic_commit_tail

2018-01-22T14:21:18+00:00

During a hardware commit, the commit bit in the backend will only be cleared if the TCON is enabled. Use the runtime_pm variant of the atomic_commit_tail hook that makes sure that the CRTC, our TCON, is enabled when we perform an atomic_commit.

drm/sun4i: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:42+00:00

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.
