drm: Free the writeback_job when it with an empty fb

2019-09-23T07:31:53Z

Adds the check if the writeback_job with an empty fb, then it should be freed in atomic_check phase. With this change, the driver users will not check empty fb case any more. So refined accordingly.

drm: Add helpers to kick off self refresh mode in drivers

2019-06-13T18:31:10Z

This patch adds a new drm helper library to help drivers implement self refresh. Drivers choosing to use it will register crtcs and will receive callbacks when it's time to enter or exit self refresh mode. In its current form, it has a timer which will trigger after a driver-specified amount of inactivity. When the timer triggers, the helpers will submit a new atomic commit to shut the refreshing pipe off. On the next atomic commit, the drm core will revert the self refresh state and bring everything back up to be actively driven. From the driver's perspective, this works like a regular disable/enable cycle. The driver need only check the 'self_refresh_active' state in crtc_state. It should initiate self refresh mode on the panel and enter an off or low-power state. Changes in v2: - s/psr/self_refresh/ (Daniel) - integrated the psr exit into the commit that wakes it up (Jose/Daniel) - made the psr state per-crtc (Jose/Daniel) Changes in v3: - Remove the self_refresh_(active|changed) from connector state (Daniel) - Simplify loop in drm_self_refresh_helper_alter_state (Daniel) - Improve self_refresh_aware comment (Daniel) - s/self_refresh_state/self_refresh_data/ (Daniel) Changes in v4: - Move docbook location below panel (Daniel) - Improve docbook with references and more detailed explanation (Daniel) - Instead of register/unregister, use init/cleanup (Daniel) Changes in v5: - Resolved conflict in drm_atomic_helper.c #include block - Resolved conflict in rst with HDCP helper docs Changes in v6: - Fix include ordering, clean up forward declarations (Sam) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-2-sean@poorly.run Link to v2: https://patchwork.freedesktop.org/patch/msgid/20190326204509.96515-1-sean@poorly.run Link to v3: https://patchwork.freedesktop.org/patch/msgid/20190502194956.218441-6-sean@poorly.run Link to v4: https://patchwork.freedesktop.org/patch/msgid/20190508160920.144739-6-sean@poorly.run Link to v5: https://patchwork.freedesktop.org/patch/msgid/20190611160844.257498-6-sean@poorly.run Cc: Daniel Vetter Cc: Jose Souza Cc: Zain Wang Cc: Tomasz Figa Cc: Ville Syrjälä Cc: Sam Ravnborg Tested-by: Heiko Stuebner Reviewed-by: Daniel Vetter Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/20190612145026.191846-1-sean@poorly.run

drm: Add drm_atomic_get_(old|new)_connector_for_encoder() helpers

2019-06-13T17:00:29Z

Add functions to the atomic core to retrieve the old and new connectors associated with an encoder in a drm_atomic_state. This is useful for encoders and bridges that need to access the connector, for instance for the drm_display_info. The CRTC associated with the encoder can also be retrieved through the connector state, and from it, the old and new CRTC states.

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

drm: Add a new plane property to send damage during plane update

2018-12-05T09:00:35Z

FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.
