The PUT_STREAM_BUFFER and ENCODE_FRAME request have fields that allow to pass arbitrary 64 bit values through the firmware to the ENCODE_FRAME response. Use these values to verify that the buffers when finishing the frame are actually the same buffers that have been sent for encoding a frame. Signed-off-by:

The V4L2_CID_MPEG_VIDEO_FRAME_RC_ENABLE control allows to enable/disable rate control on a channel. When rate control is disabled, the driver shall use constant QP, which are set by the application. Also implement the controls for configuring the QP. Signed-off-by:

The allegro dvt codec adjust the encoding speed according to a configured frame rate. Furthermore, the frame rate is written into the coded stream. Ensure that the coded video data has the correct frame rate by implementing s_parm for setting the frame rate from user space. Signed-off-by:

The driver instructs the firmware to leave some space space in front of the coded frame data for SPS/PPS data. If the driver receives an IDR, it writes the SPS/PPS into that free space and fills the rest with filler data. However, if there is no additional data, the driver can use the plane offset to skip this space instead of adding filler data. As the size of the SPS/PPS is only available after writing it, keep the filler data between the SPS/PPS and the coded frame data. Signed-off-by:

The driver uses structs to parse the responses from the VCU and expects a certain size of the responses. However, the size and format of the mails is not stable across firmware versions. Therefore, print a warning if the size does not match the expected size to warn the user that strange things might happen. Signed-off-by:

The mcu and the codec use 32 bit addresses which are sent via the firmware messages. Add helper functions for this address calculation to make it obvious which address is used in the message. As the mcu and the codec have a limited address space, print warnings if the addresses are outside the respective address space. Signed-off-by:

The Zynq UltraScale+ Devices Register Reference states that the WAKEUP bit "should be set to 0 after the MCU sleep status bit gets back to 0." If this is not done, the mcu is not going to sleep on reset and fail the reset. Set WAKEUP to 0 before triggering a reset to make sure that the reset is successful. Signed-off-by:

The cpb_size is given in kilobytes, but the bitrate is given in bits per second. Therefore, the calculation of the initial removal delay and the cpb size for the firmware were wrong. Convert the bitrate to kilobytes before calculating the cpb size in 90 kHz units for sending it to the firmware. Also reuse the result for the initial removal delay, to make it obvious that we are setting the initial removal delay to the maximum value. Signed-off-by:

When creating a channel, freq_idr defines the number of frames between IDR frames in the coded stream. In V4L2, the period between IDR frames shall be taken from the GOP_SIZE control. Set the IDR frame frequency equal to the GOP size and let every GOP start with an IDR frame. Signed-off-by:

The subframe_latency and lda_control_mode fields directly follow freq_golden_ref field and there is no unknown field in between. The unknown field it at the end of the message. Reorder the fields accordingly. This further allows to drop the hard coded value from the lda_control_mode field and set the mode to 0. Signed-off-by:

Michael Tretter authored
The gop_length field is actually only u16 and there are two more u8 fields in the message: - the number of consecutive b-frames - frequency of golden frames Fix the message and thus fix the configuration of the GOP length. Signed-off-by:

Only negative values are actual errors and positive values are used for warnings. Warnings should not fail the encoding process. Signed-off-by:

Since commit cc62c747 ("media: allegro: add missed checks in allegro_open()") the allegro device does provide v4l2 controls to user space anymore. The reason is that v4l2_fh_init() initializes fh->ctrl_handler to vdev->ctrl_handler, which invalidates the previous driver override of the ctrl_handler. Therefore, v4l2_fh_init() must be called before the driver overrides the fh->ctrl_handler with its own handler. Move the initialization of the fh back to the top, as the initialization does not does not need to be reverted on errors, but it is enough to free the channel.

The driver doesn't really support V4L2_PIX_FMT_Y16, as there's no 16-bit greyscale media bus code defined by the kernel. It (ab)uses the format to capture 10-bit and 12-bit greyscale formats. Fix it to properly support MEDIA_BUS_FMT_Y10_1X10 and MEDIA_BUS_FMT_Y12_1X12 instead. Signed-off-by:

Commit 4791bd7d ("media: imx: Try colorimetry at both sink and source pads") reworked the way that formats are set on the sink pad of the CSI subdevice, and accidentally removed video field handling. Restore it by defaulting to V4L2_FIELD_NONE if the field value isn't supported, with the only two supported value being V4L2_FIELD_NONE and V4L2_FIELD_INTERLACED.

The imx7_csi_dma_reflash() function starts by reading the unrelated register CSI_CSICR18 to then overwrite the read value with a read from register CSI_CSICR3. This is likely due to a bad copy&paste, and is not needed. Remove the extraneous read from register CSI_CSICR18.

Enable filtering based on CSI-2 data type. Otherwise sources that send multiple data types (such as sensors that send embedded data) will not be properly supported. They will both result in additional non-image lines being captured, and in the receiver being confused as it doesn't resynchronise on vsync. Signed-off-by:

Make sure to check that we have two alternate settings and at least one endpoint before accessing the second altsetting structure and dereferencing the endpoint arrays. This specifically avoids dereferencing NULL-pointers or corrupting memory when a device does not have the expected descriptors. Note that the sanity check in cit_get_packet_size() is not redundant as the driver is mixing looking up altsettings by index and by number, which may not coincide.
