dib7000p is for DVB, and not ISDB. So, there's no layer. That removes this compilation warning: drivers/media/dvb-frontends/dib7000p.c:1972: warning: 'i' is used uninitialized in this function Signed-off-by:

The warning is simple: drivers/media/v4l2-core/v4l2-ctrls.c:1685:15: warning: incorrect type in assignment (different address spaces) but the fix isn't. The core problem was that the conversion from user to kernelspace was done at too low a level and that needed to be moved up. That made it possible to drop pointers to v4l2_ext_control from set_ctrl and validate_new and clean up this sparse warning because those functions now always operate on kernelspace pointers.

The NV12M is supported by all the version of MFC, so it is better to use it as default OUTPUT format. MFC v5 doesn't support NV21, I have tested it, for the SEC doc it is not supported either. Signed-off-by:

Patch b906352c ([media] coda: dequeue buffers if start_streaming fails) incorrectly marked buffers as DEQUEUED in case of start_streaming failure, when in fact they should be set to QUEUED. The videobuf2 core warns about this. Reported-by:

Interrupt result flags have to be cleared before a hardware job is run. Otherwise, if they are cleared asynchronously, we may end up clearing them after the interrupt for which we wanted to wait has already arrived, thus overwriting the job results that we intended to wait for. To prevent this, clear the flags only under hw_lock and before running a hardware job. Signed-off-by:

While resolution change is detected by MFC, we flush out older dpbs, send the resolution change event to application, and then accept further queuing of new src buffers. Sometimes, we error out during dpb flush because of lack of src buffers. Since we have not started decoding new resolution yet, it is simpler to push zero-size buffer until we flush out all dpbs. This is already been done while handling EOS command, and this patch extends the same logic to resolution change as well. Signed-off-by:

Pawel Osciak authored
If the software watchdog kicks in, the watchdog worker is not synchronized with hardware interrupts and does not block other instances. It's possible for it to clear the hw_lock, making other instances trigger a BUG() on hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice, just WARN in those cases for now. We should not explode, as firmware will return errors as needed for other instances after it's reloaded, or they will time out. A clean fix should involve killing other instances when watchdog kicks in, but requires a major redesign of locking in the driver. Signed-off-by:

Timestamp i of a previously decoded buffer was overwritten for some H.264 streams with timestamp i+1 of the next buffer. This happened when encountering frame_type S5P_FIMV_DECODE_FRAME_SKIPPED, indicating no new frame. In most cases this wrong indexing might not have been noticed except for a one frame delay in frame presentation. For H.264 streams though that require reordering of frames for presentation, it caused a slightly erratic presentation time lookup and consequently dropped frames in the Pepper Flash plugin.

The enter_suspend flag is set after we enter mfc suspend function but if suspend fails after that due to any reason (like hardware timeout etc), this flag must be cleared before returning an error. Otherwise, this flag never gets cleared and the MFC suspend will always return an error on subsequent tries. If clock off fails, disable hw_lock also. Signed-off-by:

For small frame sizes, allocating 1 MiB per compressed buffer is a waste of space. On the other hand, incompressible 1080p data can produce JPEGs larger than 1 MiB at higher quality settings. Allow userspace to set the compressed buffer size and clamp the value to a sensible range. Also set the initial sizeimage to a value inside the range allowed by try_fmt. While at it, reduce the default image size to a maximum of 1920*1088 (otherwise JPEG will default to 8k*8k and 96 MiB buffers). Signed-off-by:

With bitstream padding, it is possible to decode a single JPEG in the bitstream immediately. This allows us to only ever queue a single JPEG into the bitstream buffer, except to increase payload over 512 bytes or to back out of hold state. This is a measure to decrease JPEG decoder latency.

Storing the buffer position in the bitstream with the buffer metadata allows to later use that information to drop metadata for skipped buffers and to determine whether bitstream padding has to be applied. This patch also renames struct coda_timestamp to struct coda_buffer_meta to make clear that it contains more than only the buffer timestamp. Signed-off-by:

This patch adds JPEG encoding and decoding support for CODA7541, using the BIT processor. Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG. Signed-off-by:
