2020-03-18drm: convert .debugfs_init() hook to return void.Wambui Karuga
As a result of commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) and changes to various debugfs functions in drm/core and across various drivers, there is no need for the drm_driver.debugfs_init() hook to have a return value. Therefore, declare it as void. This also includes refactoring all users of the .debugfs_init() hook to return void across the subsystem. v2: include changes to the hook and drivers that use it in one patch to prevent driver breakage and enable individual successful compilation of this change.

2020-03-18drm/sti: remove use of drm_debugfs functions as return valuesWambui Karuga
Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files() never fails, and should return void. This change therefore removes it uses as a return value in various functions across drm/sti. With these changes, the affected functions have been changed to use a void return value. v2: convert sti_mixer_debugfs_init() and sti_compositor_debugfs_init() to return void too. Also have sti_drm_dbg_init() to return 0 to avoid build issues.

2020-02-26drm/bridge: Extend bridge API to disable connector creationLaurent Pinchart
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

We are about to add a drm_bridge_state that inherits from drm_private_state which is defined in drm_atomic.h.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

drm_plane_helper_disable is a non-atomic drivers only function, and will blow up (since no one passes the locking context it needs). Atomic drivers which want to quiescent their hw on unload should use drm_atomic_helper_shutdown() instead. The sti cleanup code seems supremely confused: - In the load error path it calls drm_mode_config_cleanup before it stops various kms services like poll worker or fbdev emulation. That's going to oops. - The actual unload code doesn't even bother with the cleanup and just leaks. Try to fix this while at it.

2018-09-25drm/sti: Use drm_fbdev_generic_setup()Noralf Trønnes
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(). If drm_fbdev_generic_setup() fails, an error is printed by the function. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.
