While normal video/radio/vbi/swradio nodes have a proper QUERYCAP ioctl that apps can call to determine that it is indeed a V4L2 device, there is currently no equivalent for v4l-subdev nodes. Adding this ioctl will solve that, and it will allow utilities like v4l2-compliance to be used with these devices as well. SUBDEV_QUERYCAP currently returns the version and capabilities of the subdevice. Define a capability flag to report if the subdevice is registered in read-only mode. Signed-off-by:

A sub-device device node can be registered in user space only if the CONFIG_VIDEO_V4L2_SUBDEV_API Kconfig option is selected. Currently the open/close file operations and the ioctl handler have some parts of their implementations guarded by #if defined(CONFIG_VIDEO_V4L2_SUBDEV_API), while they are actually not accessible without a video device node registered to user space. Guard the whole open, close and ioctl handler and provide stubs if the VIDEO_V4L2_SUBDEV_API Kconfig option is not selected. This slightly reduces the kernel size when the option is not selected and simplifies the file ops and ioctl implementations. Signed-off-by:

Add to the V4L2 core a function to register device nodes for video subdevices in read-only mode. Registering a device node in read-only mode is useful to expose to userspace the current sub-device configuration, without allowing application to change it by using the V4L2 subdevice ioctls. Acked-by:

Rework the documentation to make it easier for the reader to understand the differences in behavior of this ioctl between MC and non-MC drivers. Note the addition of the 'video-node-centric' and 'MC-centric' terms to help understand what the IO_MC capability really means. Also mention in the beginning that mbus_code is one of the fields that application should initialize, and add META_OUTPUT as one of the types that this ioctl supports (that was never added here when the META_OUTPUT buffer type was added). Finally document that EINVAL will be returned if mbus_code is unsupported. Fixes: e5b6b07a ("media: v4l2: Extend VIDIOC_ENUM_FMT to support MC-centric devices") Signed-off-by:

The VIDIOC_ENUM_FMT ioctl enumerates all formats supported by a video node. For MC-centric devices, its behaviour has always been ill-defined, with drivers implementing one of the following behaviours: - No support for VIDIOC_ENUM_FMT at all - Enumerating all formats supported by the video node, regardless of the configuration of the pipeline - Enumerating formats supported by the video node for the active configuration of the connected subdevice The first behaviour is obviously useless for applications. The second behaviour provides the most information, but doesn't offer a way to find what formats are compatible with a given pipeline configuration. The third behaviour fixes that, but with the drawback that applications can't enumerate all supported formats anymore, and have to modify the active configuration of the pipeline to enumerate formats. The situation is messy as none of the implemented behaviours are ideal, and userspace can't predict what will happen as the behaviour is driver-specific. To fix this, let's extend the VIDIOC_ENUM_FMT with a missing capability: enumerating pixel formats for a given media bus code. The media bus code is passed through the v4l2_fmtdesc structure in a new mbus_code field (repurposed from the reserved fields). With this capability in place, applications can enumerate pixel formats for a given media bus code without modifying the active configuration of the device. The current behaviour of the ioctl is preserved when the new mbus_code field is set to 0, ensuring compatibility with existing userspace. The API extension is documented as mandatory for MC-centric devices (as advertised through the V4L2_CAP_IO_MC capability), allowing applications and compliance tools to easily determine the availability of the VIDIOC_ENUM_FMT extension.

Add a video device capability flag to indicate that its inputs and/or outputs are controlled by the Media Controller instead of the V4L2 API. When this flag is set, ioctl for enum inputs and outputs are automatically enabled and programmed to call a helper function. Suggested-by:

The log_addrs->log_addr_type[i] value is a u8 which is controlled by the user and comes from the ioctl. If it's over 31 then that results in undefined behavior (shift wrapping) and that leads to a Smatch static checker warning. We already cap the value later so we can silence the warning just by re-ordering the existing checks. I think the UBSan checker will also catch this bug at runtime and generate a warning. But otherwise the bug is harmless. Fixes: 9881fe0c ("[media] cec: add HDMI CEC framework (adapter)") Signed-off-by:

The function imx_media_init_mbus_fmt() initializes the imx subdevice mbus colorimetry to some sane defaults when the subdevice is registered. Currently it guesses at a colorspace based on the passed mbus pixel format. If the format is RGB, it chooses colorspace V4L2_COLORSPACE_SRGB, and if the format is YUV, it chooses V4L2_COLORSPACE_SMPTE170M. While that might be a good guess, it's not necessarily true that a RGB pixel format encoding uses a SRGB colorspace, or that a YUV encoding uses a SMPTE170M colorspace. Instead of making this dubious guess, just default the colorspace to SRGB. Reported-by:
