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.

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.

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.

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.

According to stateful Codec API the decoder will process all remaining buffers from before the source change event in dynamic-resolution-change state and mark the last buffer with V4L2_BUF_FLAG_LAST. In Venus case the firmware doesn't mark that last buffer and some mechanism have to be created in v4l decoder driver. Fortunately the firmware interface (HFI) claims that the decoder output buffers will be returned to v4l decoder driver before it send the insufficient event. In order to do that we save last queued in the driver capture buffer in the event_notify and issue flush on output firmware buffers queue. Once the saved buffer is returned (as a result of flush command) we mark it as LAST. For all that possible we extend HFI flush command with one more argument and one more flush_done HFI driver callback.

Presently the list initialization is done only in dynamic-resolution-change state, which leads to list corruptions and use-after-free. Init list_head unconditionally in vdec_stop_capture called by vb2 stop_streaming without takeing into account current codec state.

Once the hfi_session_flush is issued by the vdec all queued buffers to firmware should be returned to the v4l driver. Some of those buffers are not processed at the time of flush command, those buffers has filled len zero (no data). Catch that in buffer_done callback and mark not filled capture buffers with error state so that client can discard them.
