Syzbot reported that -1 is used as array index. The problem was in missing validation check. hdw->unit_number is initialized with -1 and then if init table walk fails this value remains unchanged. Since code blindly uses this member for array indexing adding sanity check is the easiest fix for that. hdw->workpoll initialization moved upper to prevent warning in __flush_work.

Describe the coding tree unit as replacement for the macroblock in the HEVC codec. Highlight a key difference of the HEVC codec to predecessors like AVC(H.264) to give a better overview of the differences between the coding standards.

VP9 support has been added to the driver by commit f25709c4 ("media: rkvdec: Add the VP9 backend"). And the VP9 uABI was merged with commit b88dbe38 ("media: uapi: Add VP9 stateless decoder controls"). The remaining codec that keeps this driver in staging is HEVC. Update the TODO list accordingly.

To support dynamic resolution change, driver should meet the following conditions: 1. the previous pictures are all decoded before source change event. 2. prevent decoding new resolution pictures with incorrect capture buffer, until user handle source change event and setup capture. 3. report correct fmt and resolution during source change.

The decoder will save the precision that was detected from jpeg header and use it later, when choosing the pixel format and also calculate bytesperline according to precision. The 12bit jpeg is not supported yet, but driver shouldn't led to serious problem if user enqueue a 12 bit jpeg. And the 12bit jpeg is supported by hardware, driver may support it later.

The RDACM20 camera supports a single image format which is currently listed as MEDIA_BUS_FMT_UYVY8_2X8. As the video stream is transmitted on the GMSL serial bus, the 2X8 variant does not apply. Fix the format by using MEDIA_BUS_FMT_UYVY8_1X16. This fixes a runtime error which is now triggered as the MAX9286 deserializer implements .link_validate(). Signed-off-by:

Add a check to make sure the input interface (CSI-2 or parallel) allow for the requested input bus format. If not inform the user and error out rather then try to continue with incorrect settings. While at it add the missing define for RGB666 that is not yet supported in the driver but we can preemptively check for it in this context already. Signed-off-by:

smb_word_op() has a parameter data_format that determines if the data is either a byte or word. From inspection, smb_word_op() is only used by the macros smb_wr16() and smb_rd16() both pass in CMD_WORD_DATA. There is no use of smb_word_op() that passes in CMD_BYTE_DATA. So remove the byte handling. Signed-off-by:

This patch aims to add UVC_GUID_FORMAT_H265 High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2. They describe the same video encoding method. So for handling their behavior is the same. However, when external camera device describes this encoding method, some use hevc, some use h265. There is no uniform specification to describe this encoding method. So if an external camera device use h265 to describe this encoding method, driver will not recognize it. Therefore, this patch is to enable driver to read HEVC/H265 and convert it to V4L2_PIX_FMT_HEVC. Signed-off-by:
