2020-10-09drm/atomic: Pass the full state to CRTC atomic enable/disableMaxime Ripard1-2/+2
If the CRTC driver ever needs to access the full DRM state, it can't do so at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state will have cleared the pointer from the struct drm_crtc_state to the struct drm_atomic_state before calling those hooks. In order to allow that, let's pass the full DRM state to atomic_enable and atomic_disable. The conversion was done using the coccinelle script below, built tested on all the drivers and actually tested on vc4. virtual report @@ struct drm_crtc_helper_funcs *FUNCS; identifier dev, state; identifier crtc, crtc_state; @@ disable_outputs(struct drm_device *dev, struct drm_atomic_state *state) { <... - FUNCS->atomic_disable(crtc, crtc_state); + FUNCS->atomic_disable(crtc, state); ...> } @@ struct drm_crtc_helper_funcs *FUNCS; identifier dev, state; identifier crtc, crtc_state; @@ drm_atomic_helper_commit_modeset_enables(struct drm_device *dev, struct drm_atomic_state *state) { <... - FUNCS->atomic_enable(crtc, crtc_state); + FUNCS->atomic_enable(crtc, state); ...> } @@ identifier crtc, old_state; @@ struct drm_crtc_helper_funcs { ... - void (*atomic_enable)(struct drm_crtc *crtc, struct drm_crtc_state *old_state); + void (*atomic_enable)(struct drm_crtc *crtc, struct drm_atomic_state *state); ... - void (*atomic_disable)(struct drm_crtc *crtc, struct drm_crtc_state *old_state); + void (*atomic_disable)(struct drm_crtc *crtc, struct drm_atomic_state *state); ... } @ crtc_atomic_func @ identifier helpers; identifier func; @@ ( static struct drm_crtc_helper_funcs helpers = { ..., .atomic_enable = func, ..., }; | static struct drm_crtc_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; ) @ ignores_old_state @ identifier crtc_atomic_func.func; identifier crtc, old_state; @@ void func(struct drm_crtc *crtc, struct drm_crtc_state *old_state) { ... when != old_state } @ adds_old_state depends on crtc_atomic_func && !ignores_old_state @ identifier crtc_atomic_func.func; identifier crtc, old_state; @@ void func(struct drm_crtc *crtc, struct drm_crtc_state *old_state) { + struct drm_crtc_state *old_state = drm_atomic_get_old_crtc_state(state, crtc); ... } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; expression E; type T; @@ void func(...) { ... - T state = E; + T crtc_state = E; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; type T; @@ void func(...) { ... - T state; + T crtc_state; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; identifier old_state; identifier crtc; @@ void func(struct drm_crtc *crtc, - struct drm_crtc_state *old_state + struct drm_atomic_state *state ) { ... } @ include depends on adds_old_state @ @@ #include <drm/drm_atomic.h> @ no_include depends on !include && adds_old_state @ @@ + #include <drm/drm_atomic.h> #include <drm/...> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/845aa10ef171fc0ea060495efef142a0c13f7870.1602161031.git-series.maxime@cerno.tech

The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels.

The HPD sense mechanism in Allwinner's old HDMI encoder hardware is more or less an input-only GPIO. Other GPIO-based HPD implementations directly return the current state, instead of polling for a specific state and returning the other if that times out. Remove the I/O polling from sun4i_hdmi_connector_detect() and directly return a known state based on the current reading. This also gets rid of excessive CPU usage by kworker as reported on Stack Exchange [1] and Armbian forums [2].

Platform glue drivers for dw_hdmi may need to access device-specific data from their .mode_valid() implementation. They currently have no clean way to do so, and one driver hacks around it by accessing the dev_private data of the drm_device retrieved from the connector. Add a priv_data void pointer to the dw_hdmi_plat_data structure, and pass it to the .mode_valid() function.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart2-2/+2
Most bridge drivers create a DRM connector to model the connector at the output of the bridge. This model is historical and has worked pretty well so far, but causes several issues: - It prevents supporting more complex display pipelines where DRM connector operations are split over multiple components. For instance a pipeline with a bridge connected to the DDC signals to read EDID data, and another one connected to the HPD signal to detect connection and disconnection, will not be possible to support through this model. - It requires every bridge driver to implement similar connector handling code, resulting in code duplication. - It assumes that a bridge will either be wired to a connector or to another bridge, but doesn't support bridges that can be used in both positions very well (although there is some ad-hoc support for this in the analogix_dp bridge driver). In order to solve these issues, ownership of the connector should be moved to the display controller driver (where it can be implemented using helpers provided by the core). Extend the bridge API to allow disabling connector creation in bridge drivers as a first step towards the new model. The new flags argument to the bridge .attach() operation allows instructing the bridge driver to skip creating a connector. Unconditionally set the new flags argument to 0 for now to keep the existing behaviour, and modify all existing bridge drivers to return an error when connector creation is not requested as they don't support this feature yet. The change is based on the following semantic patch, with manual review and edits. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .attach = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; statement S, S1; @@ int fn( struct drm_bridge *bridge + , enum drm_bridge_attach_flags flags ) { ... when != S + if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) { + DRM_ERROR("Fix bridge driver to make connector optional!"); + return -EINVAL; + } + S1 ... } @ depends on rule1 @ identifier rule1.fn; identifier bridge, flags; expression E1, E2, E3; @@ int fn( struct drm_bridge *bridge, enum drm_bridge_attach_flags flags ) { <... drm_bridge_attach(E1, E2, E3 + , flags ) ...> } @@ expression E1, E2, E3; @@ drm_bridge_attach(E1, E2, E3 + , 0 ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Tested-by: Sebastian Reichel <sebastian.reichel@collabora.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200226112514.12455-10-laurent.pinchart@ideasonboard.com
