Choose console BPP that supports RGB and remove the old fbdev bpp selection code. LCDC on AM335x has red and blue wires switched between 24 bit and 16 bit colors. If 24 format is wired for RGB colors, the 16 bit format is wired for BGR. drm_fbdev_cma_init() does not currently like anything else but RGB formats, so we must choose such bytes per pixel value that supports RGB.

Add "blue-and-red-wiring"-device tree property and update devicetree binding document. The red and blue components are reversed between 24 and 16 bit modes on am335x LCDC output pins. To get 24 RGB format the red and blue wires has to be crossed and this in turn causes 16 colors output to be in BGR format. With straight wiring the 16 color is RGB and 24 bit is BGR. The new property describes whether the red and blue wires are crossed or not. If the property is not present or its value is not recognized the legacy mode is assumed. The legacy configuration supports RGB565, RGB888 and XRGB8888 formats. However, depending on wiring, the red and blue colors are swapped in either 16 or 24-bit color modes.

Write DMA base and ceiling address with a single instruction, if available. This should make it more unlikely that LCDC would fetch the DMA addresses in the middle of an update. Having bad combination of addresses in dma base and ceiling (e.g base > ceiling) can cause unpredictaple behavior in LCDC. Signed-off-by:

The LCDC seems to expect its framebuffer ceiling address pointer to be an inclusive bound. The IP rev2 seems to cope with that but rev1 (as found on the LCDK) don't. Also note that this is what the framebuffer code does in da8xx-fb.c. Since, as the TRM puts it, "The 2 LSBs are hardwired to 00b", the dma_addr_t can be decremented without cast.

drm_kms_helper_poll_enable_locked() should check if we have delayed event pending and if we have, schedule the work to run without delay. Currently the output_poll_work is only scheduled if any of the connectors have DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT with DRM_OUTPUT_POLL_PERIOD delay. It does not matter if we have delayed event already registered to be handled. The detection will be delayd by DRM_OUTPUT_POLL_PERIOD in any case. Furthermore if none of the connectors are marked as POLL_CONNECT or POLL_DISCONNECT because all connectors are either POLL_HPD or they are always connected: the output_poll_work will not run at all even if we have delayed event marked. When none of the connectors require polling, their initial status change from unknown to connected/disconnected is not going to be handled until the first kms application starts or if we have fb console enabled. Note that in general the output poll work should be enabled already when this happens, but at driver load usually the first probe happens before the output polling is enabled. This patch fixes this case. Signed-off-by:

Just for the struct drm_mode_object base class. The header file was already partially extracted to help untangle the include loops. v2: - Also move the generic get/set property ioctls. At first this seemed like a bad idea since it requires making drm_mode_crtc_set_obj_prop non-static. But eventually that will get split away too (like the connector version already is) for both crtc and planes. Hence I reconsidered. - drm_mode_object.[hc] instead of drm_modeset.[hc], which requires renaming the drm_modeset.h header I already started building up. This is more consistent (matches the name of the main structure), and I want to be able to use drm_modeset.[hc] for the basic modeset init/cleanup functionality like drm_mode_config_init.

When CONFIG_DRM_KMS_FB_HELPER is disabled, we can have a configuration in which some DRM drivers are built-in, but the framebuffer core is a loadable module.

We could alternatively avoid the link error by forcing CONFIG_FB to not be a module in this case, but that wouldn't change anything at runtime, and just make the already convoluted set of dependencies worse here. I could not find out what happens if the fbdev driver gets loaded as a module after the DRM driver is already initialized, but that is a case that can happen with or without this patch.

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that. Suggested-by:

Currently, the helper drm_atomic_helper_disable_planes_on_crtc() calls ->atomic_disable for all planes _to be_ enabled on a particular CRTC. This is obviously wrong for those planes which are not scanning out frames when the helper is called. Instead, it's sane to disable active planes of old_crtc_state in the helper. Suggested-by:

Some display controllers need plane(s) to be disabled together with the relevant CRTC, e.g., the IPUv3 display controller for imx-drm. This patch adds atomic_disable CRTC helper callback so that old_crtc_state(as a parameter of the callback) could be used to get the active plane(s) of the old CRTC state for disable operation.

Andrea Merello authored
Up to now, once a bridge has been attached to a DRM device, it cannot be undone. In particular you couldn't rmmod/insmod a DRM driver that uses a bridge, because the bridge would remain bound to the first (dead) driver instance. This patch fixes this by introducing drm_encoder_detach() and a ->detach callback in drm_bridge_funcs for the bridge to be notified about detaches. It's DRM/KMS driver responsibility to call drm_encoder_detach(). While adding the bridge detach callback, with its kerneldoc, I also added kerneldoc for attach callback. Few other kerneldocs fixes around there are included. Suggested-by:

The *only* known user of GETCLIENT is libva, which uses it to check whether its own context is authenticated. It used to iterate all clients, look for one that matches its own pid and then check its state. The entire purpose for us to still have a GETCLIENT implementation is to serve libva. So lets not pretend we do anything else: Make this function return information on the caller's context only, fake the PID to the caller's pid so they always match, and just fill in the "authenticated" bit, nothing else. This patch reduces the complexity of GETCLIENT to a bare minimum, avoids any dependency on priv->uid or priv->pid (allows us to get rid of them), and makes libva happy by always *exactly* returning the information it wants.

The legacy DRI1 drivers expose highly broken interfaces to user-space. No modern system should enable them, or you will effectively allow user-space to circumvent most of your kernel security measures. The DRI1 kernel APIs are simply broken. User-space can always use vesafb/efifb/simplefb and friends to get working graphics. Lets hide the old drivers behind CONFIG_BROKEN. In case they turn out to be still used (really?), we can easily revert this and figure out a way to move them out of sight (e.g., moving all DRI1 drivers to drivers/gpu/dri1/). Signed-off-by:

Lets move forward and hide the remaining DRI1 drivers behind a config option, so we have a central place to disable them all. Furthermore, we can provide a clear warning to anyone enabling them. Signed-off-by:
