Adds functions to link and unlink source channels to sink channels in the FSU: int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch); int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch); The channels numbers are usually IDMAC channels, but they can also be channels that do not transfer data to or from memory. The following convenience functions can be used in place of ipu_fsu_link/unlink() when both source and sink channels are IDMAC channels: int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink); int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink); So far the following links are supported: IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC PUV3_CHANNEL_IC_PRP_VF_MEM -> IPUV3_CHANNEL_MEM_ROT_VF IPUV3_CHANNEL_IC_PP_MEM -> IPUV3_CHANNEL_MEM_ROT_PP IPUV3_CHANNEL_CSI_DIRECT -> IPUV3_CHANNEL_CSI_VDI_PREV More links can be added to the fsu_link_info[] array.

Drop the load/unload driver ops, as they are deprecated because of their inherent races, with devices being visible to userspace before they are fully initialized.

When the destroy path is called the plane should already be disabled. If not, this is a core bug and should not be worked around in the driver. Signed-off-by:

We don't support configuring active plane on-the-fly for imx-drm. The relevant CRTC should be disabled before the plane configuration. Of course, the plane itself should be disabled as well. This patch adds active plane reconfiguration support by forcing CRTC mode change in plane's ->atomic_check callback so that the CRTC will be disabled before the plane configuration. Suggested-by:

The IPUv3 display controller behind imx-drm needs all planes of a CRTC be disabled when the CRTC is disabled. The DRM_PLANE_COMMIT_NO_DISABLE_AFTER_MODESET flag reflects this hardware requirement. Let's use the flag for imx-drm. Suggested-by:

According to basic tests, it looks there is no issue if we don't wait for DMFC FIFO to clear when disabling DMFC channel. NXP BSP doesn't do that, either. This patch is needed to avoid the annoying warning caused by a timeout on waiting for the FIFO to clear after we add the new DRM_PLANE_COMMIT_NO_DISABLE_AFTER_MODESET flag to the imx-drm driver which changes the procedure to disable display channel slightly.

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:

Liu Ying authored
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:

Liu Ying authored
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.

drm_simple_display_pipe_init() pretends to attach a connector to the display pipe. In case a drm bridge has to be used, then it's the bridge that takes care of connectors. This patch makes the connector parameter optional for drm_simple_display_pipe_init(), so that a drm bridge could handle connector by itself later. Signed-off-by:
-
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:

Our update function is hooked to the single plane, which might not get called for crtc-only updates. Which is surprising, so fix this by always adding the plane. While at it document how&when the event should be sent out better in the kerneldoc.

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:

Commit d112a816 ("gma500/cdv: Add eDP support") replaced the code inside this if-conditional with gma_backlight_set(), which becomes a nop stub if CONFIG_BACKLIGHT_CLASS_DEVICE is disabled. So, there is no need to guard the caller with config_enabled(). Note: This is one of remaining TODOs to deprecate config_enabled() macro. Refer to commit 97f2645f ("tree-wide: replace config_enabled() with IS_ENABLED()"). Signed-off-by:

Everyone knows them, except all the new folks joining from the ARM side haven't lived through all the pain of the past years and are entirely surprised when I raise this. Definitely time to document this. Last time this was a big discussion was about 6 years ago, when qcom tried to land a kernel driver without userspace.

This adds a function that also takes the console lock before calling fb_set_suspend() in contrast to drm_fb_helper_set_suspend() which is a plain wrapper around fb_set_suspend().

We always need to remove conflicting framebuffers if any other fb driver is enabled, and not just if we are setting up an fbdev ourselves. Unfortunately remove_conflicting_framebuffers() was incorrectly stubbed out if !fbdev rather than !fb leading to major memory corruption (and corrupt filesystems) upon boot.
