[media] c8sectpfe: use setup_timer

2017-04-10T17:56:17Z

Use setup_timer() instead of init_timer() to simplify the code. Signed-off-by: Geliang Tang Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] stih-cec: add CEC notifier support

2017-04-10T15:53:51Z

By using the CEC notifier framework there is no longer any reason to manually set the physical address. This was the one blocking issue that prevented this driver from going out of staging, so do this move as well.

[media] bdisp: Clean up file handle in open() error path

The File handle is not yet added in the vdev list.So no need to call v4l2_fh_del(&ctx->fh)if it fails to create control. Signed-off-by: Shailendra Verma Reviewed-by: Fabien Dessenne Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] st-delta: debug: trace stream/frame information & summary

2017-02-08T12:07:29Z

Adds some trace points showing input compressed stream or output decoded frame information. Adds an unconditional trace point when streaming starts showing the compressed stream and the decoded frame information. Adds an unconditional trace point at instance closure summarizing into a single line the decoding process (stream information, decoded and output frames number, potential errors observed).

[media] st-delta: add mjpeg support

2017-02-08T12:06:16Z

Adds support of DELTA MJPEG video decoder back-end, implemented by calling JPEG_DECODER_HW0 firmware using RPMSG IPC communication layer. Acked-by: Peter Griffin Signed-off-by: Hugues Fruchet Signed-off-by: Mauro Carvalho Chehab

[media] st-delta: EOS (End Of Stream) support

2017-02-08T12:04:28Z

EOS (End Of Stream) support allows user to get all the potential decoded frames remaining in decoder pipeline after having reached the end of video bitstream. To do so, user calls VIDIOC_DECODER_CMD(V4L2_DEC_CMD_STOP) which will drain the decoder and get the drained frames that are then returned to user. User is informed of EOS completion in two ways: - dequeue of an empty frame flagged to V4L2_BUF_FLAG_LAST - reception of a V4L2_EVENT_EOS event. If, unfortunately, no buffer is available on CAPTURE queue to return the empty frame, EOS is delayed till user queue one CAPTURE buffer.

[media] st-delta: rpmsg ipc support

2017-02-08T12:03:49Z

IPC (Inter Process Communication) support for communication with DELTA coprocessor firmware using rpmsg kernel framework. Based on 4 services open/set_stream/decode/close and their associated rpmsg messages. The messages structures are duplicated on both host and firmware side and are packed (use only of 32 bits size fields in messages structures to ensure packing). Each service is synchronous; service returns only when firmware acknowledges the associated command message. Due to significant parameters size exchanged from host to copro, parameters are not inserted in rpmsg messages. Instead, parameters are stored in physical memory shared between host and coprocessor. Memory is non-cacheable, so no special operation is required to ensure memory coherency on host and on coprocessor side. Multi-instance support and re-entrance are ensured using host_hdl and copro_hdl in message header exchanged between both host and coprocessor. This avoids to manage tables on both sides to get back the running context of each instance. Acked-by: Peter Griffin Signed-off-by: Hugues Fruchet Signed-off-by: Mauro Carvalho Chehab
