The AWB workqueue runs in a kernel thread and needs to be synchronized w.r.t. the streaming status. It is possible that streaming is stopped while the AWB workq is running. In this case it is likely that the check for vb2_start_streaming_called is done at one point in time, but the AWB computations are done later, including a call to isc_update_profile, which requires streaming to be started. Thus , isc_update_profile will fail if during this operation sequence the streaming was stopped. To solve this issue, a mutex is added, that will serialize the awb work and streaming stopping, with the mention that either streaming is stopped completely including termination of the last frame is done, and after that the AWB work can check stream status and stop; either first AWB work is completed and after that the streaming can stop correctly. The awb spin lock cannot be used since this spinlock is taken in the same context and using it in the stop streaming will result in a recursion BUG. Signed-off-by:

While this does not happen in production, this check should be done versus the mask, as checking with the YCYC value may not include some bits that may be set. It is correct and safe to check the whole mask. Fixes: 123aaf81 ("media: atmel: atmel-sama5d2-isc: fix YUYV format") Signed-off-by:

In s_fmt_vid_cap, we should check if vb2_is_busy and return EBUSY, not check if it's streaming to return the busy state. Suggested-by:

During experiments with libcamera, it looks like vb2_is_streaming returns true before our start streaming is called. Order of operations is streamon -> queue -> start_streaming ISC would have started the DMA immediately when a buffer is being added to the vbqueue if the queue is streaming. It is more safe to start the DMA after the start streaming of the driver is called. Thus, even if vb2queue is streaming, add the buffer to the dma queue of the driver instead of actually starting the DMA process, if the start streaming has not been called yet. Tho achieve this, we have to use vb2_start_streaming_called instead of vb2_is_streaming. Signed-off-by:

The vertical subsampling factor is currently not considered in the offset calculation for plane cropping done in rpf_configure_partition. This causes a distortion (shift of the color plane) when formats with the vsub factor larger than 1 are used (e.g. NV12, see vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor for all planes except plane 0 (luminance). Drop generalization of the offset calculation to reduce the binary size.

Use the vb2_fop_release() helper to replace the open-coded version. The video->lock is assigned to the queue lock, used by vb2_fop_release(), so the only functional difference is that v4l2_fh_release() is now called before vsp1_device_put(). This should be harmless. Signed-off-by:

vb2 queue ownership is managed by the ioctl handler helpers (vb2_ioctl_*). There are however use cases where drivers can benefit from checking queue ownership, for instance when open-coding an ioctl handler that needs to perform additional checks before calling the corresponding vb2 operation. Expose the vb2_queue_is_busy() function in the videobuf2-v4l2.h header, and change its first argument to a struct vb2_queue pointer as the function name implies it operates on a queue, not a video_device.

That's wrong, and may lead the caller to use a weird value. Signed-off-by: -

After that, there is no need to make a workaround for poll function. driver can use v4l2_m2m_fop_poll directly. Also, driver don't need to keep a input threshold as the buffer count is up to only 32.

Fix build errors when RADIO_TEA575X=y, VIDEO_BT848=m, and VIDEO_DEV=m. The build errors occur due to [in drivers/media/Makefile]: obj-$(CONFIG_VIDEO_DEV) += radio/ so the (would be) builtin tea575x.o is not being built. This is also due to drivers/media/radio/Kconfig declaring a bool Kconfig symbol (RADIO_ADAPTERS) that depends on a tristate (VIDEO_DEV), so when VIDEO_DEV=m, RADIO_ADAPTERS becomes =y, and then the drivers that depend on RADIO_ADPATERS can be configured as builtin (=y) or as loadable modules (=m). Fix this by converting RADIO_ADAPTERS to a tristate symbol instead of a bool symbol. Fixes these build errors: ERROR: modpost: "snd_tea575x_hw_init" [drivers/media/pci/bt8xx/bttv.ko] undefined!

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.
