drm: Unexport drm_plane_helper_check_update

2018-10-05T20:45:19Z

It's for legacy drivers only (atomic ones should use drm_atomic_helper_check_plane_state() instead), and there's no users left except the one in the primary plane helpers.

drm: Unexport primary plane helpers

2018-10-05T16:06:49Z

Well except the destroy helper, which isn't really a primary helper but generally useful, if mislabelled. v2: Keep some of the nice comments about the limitations of the primarmy plane helpers, and put them into the kerneldoc for drm_crtc_init() (Sam).

drm: Remove transitional helpers

2018-10-05T16:04:10Z

With armada the last bigger driver that realistically needed these to convert from legacy kms to atomic is converted. These helpers have been broken more often than not the past 2 years, and as this little patch series shows, tricked a bunch of people into using the wrong helpers for their functions. Aside: I think a lot more drivers should be using the device-level drm_atomic_helper_shutdown/suspend/resume helpers and related functions. In almost all the cases they get things exactly right.

drm: add missing ctx argument to plane transitional helpers

2018-07-03T07:30:19Z

In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

drm: Move drm_plane_helper_check_state() into drm_atomic_helper.c

2017-11-20T19:14:22Z

drm_plane_helper_check_update() isn't a transitional helper, so let's rename it to drm_atomic_helper_check_plane_state() and move it into drm_atomic_helper.c. v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Cc: Daniel Vetter Suggested-by: Daniel Vetter Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20171101201619.6175-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter

drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()

2017-11-20T18:33:21Z

drm_plane_helper_check_state() is supposed to do things the atomic way, so it should not be inspecting crtc->enabled. Rather we should be looking at crtc_state->enable. We have a slight complication due to drm_plane_helper_check_update() reusing drm_plane_helper_check_state() for non-atomic drivers. Thus we'll have to pass the crtc_state in manally and construct a fake crtc_state in drm_plane_helper_check_update(). v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20171101201558.6059-1-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter
