Currently the platform device pointer is stored in struct coda_dev, only to convert it into a device pointer wherever it is used. Just store the device pointer directly. Signed-off-by:

If reordering is not enabled, the last decoded frame has to be the last returned buffer. Otherwise wait for the firmware to report no more frame to display. In that case the return buffer is the last one as well, and can be reported as such. Signed-off-by:

If there is still a buffer pending, mark it as the last buffer. It will create a meta that is flagged as last when the buffer is copied into the bitstream ring buffer. If there are no more buffers pending, find the last bitstream meta and mark it as last. If there is no bitstream meta either, wake up the capture queue as there will be no more decoded frames.

Make sure that an encoder stop command running concurrently with an encoder finish_run always either flags the last returned buffer or wakes up the capture queue to signal the end of stream condition afterwards. Signed-off-by:

Use the flagged last output buffer to also flag the corresponding capture buffer after encoding. This causes the end of stream event to be issued and the buffer to be dequeued with the last flag set. Signed-off-by:

If there are no pending queued output buffers to be encoded, waking up the capture queue with -EPIPE signals end of stream. If there are pending buffers on the other hand, setting the V4L2_BUF_FLAG_LAST on the resulting encoded capture buffers is all that is needed. Signed-off-by:

Using the output queue sequence counter to determine the last buffer to be encoded or decoded always was fragile at best. Now that we have the last buffer flag propagating from the output queue to the capture queue correctly, this is not needed anymore. Signed-off-by:

Mark the last output buffer to be encoded. Signed-off-by:

Philipp Zabel authored
If there are still queued output buffers pending to be copied into the bitstream ring buffer, setting the stream end flag should be deferred until the marked last output buffer is written into the bitstream ring buffer. Signed-off-by:

Mark the last output buffer to be decoded and only copy pending queued output buffers into the bitstream ring buffer in the BIT processor decoder case. Signed-off-by:
-
Philipp Zabel authored
Since V4L2_BUF_FLAG_LAST is a CAPTURE only flag, clear it from OUTPUT buffers in QBUF and DQBUF. This allows to use the flag internally to signal the last buffer to decode after a decoder stop command was issued. Signed-off-by:

Philipp Zabel authored
If no more frames are decoded in bitstream end mode, and a previously decoded frame has been returned, the firmware still increments the frame number. To avoid a sequence number mismatch after decoder restart, increment the sequence_offset correction parameter. Signed-off-by:

The bitstream ringbuffer might be in an underrun state after draining, or it might still contain unread data if the previous decoder stop command was flagged as immediate. Flush the bitstream ring buffer during V4L2_DEC_CMD_START to get into a well defined state. Also fill the bitstream with buffers that have been queued during draining, to resume decoding immediately.

On CODA960, sequence initialization can succeed if less than 512 bytes are ready in the bitstream ring buffer. On other variants, warn about too small payload in start_streaming. Signed-off-by:
-
Philipp Zabel authored
If the first buffer contains only headers, the sequence initialization command fails. On CodaHx4 the buffer must be padded to at least 512 bytes, on CODA960 it seems to be enough to just repeat the sequence and extension headers (MPEG-2) or the VOS and VO headers (MPEG-4) once for for sequence initialization to succeed without further bitstream data. On CodaHx4 the headers can be repeated multiple times until the 512 byte mark is reached. A similar issue was solved for h.264 by padding with a filler NAL in commit 0eef8940 ("[media] coda: pad first h.264 buffer to 512 bytes"). Signed-off-by:

Add a sequence initialization work item to be run when OUTPUT buffers are queued in the initialization state. Signed-off-by:
-
Philipp Zabel authored
The sequence initialization already has to happen during the initialization phase, after headers have been queued on the OUTPUT queue. This means that sequence initialization has to be queued as a work item from QBUF on the OUTPUT queue. The internal framebuffer setup should be done later during VIDIOC_REQBUFS() on the CAPTURE queue. Signed-off-by:

When the DEC_CMD_STOP command is issued after the context has already consumed all the queued buffers, we need to make sure to wake the destination queue with last_buffer_dequeued set, to allow userspace to make progress in its EOS handling. As there might still be picture run workers pending at that point, we need to synchronize with them, so the sequence number comparison reads stable values. reword commit message] Signed-off-by:

Combine setting the last_buffer_dequeued flag on the capture video queue and waking up its done workqueue into a helper function. Signed-off-by:
-
Marco Felsch authored
coda_encoder_cmd() is racy, as the last scheduled picture run worker can still be in-flight while the ENC_CMD_STOP command is issued. Depending on the exact timing the sequence numbers might already be changed, but the last buffer might not have been put on the destination queue yet. In this case the current implementation would prematurely wake the destination queue with last_buffer_dequeued=true, causing userspace to call streamoff before the last buffer is handled. Close this race window by synchronizing with the pic_run_worker before doing the sequence check. Signed-off-by:

Sequence number handling assumed that the BIT processor frame number starts counting at 1, but this is not true for the MPEG-2 decoder, which starts at 0. Fix the sequence counter offset detection to handle this. Signed-off-by:

The CMD_START shall be used to start the processing after a drain that was initiated with CMD_STOP. Up until now, a drain on coda could only be finished with a STREAMOFF-STREAMON, which resulted in a reset of the device. Signed-off-by:

Ask device connected on sink pad for link frequency in order to configure CLK_LANE_REG1 (ui_x4). If not available, ask for pixel rate information to compute it. This is needed to deal with compressed format such as JPEG where number of bits per pixel is unknown: computation of link frequency from pixel rate is not possible. Signed-off-by:

The sensor needs the MCLK clock running when it's being probed. On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent. It was always the case. Signed-off-by:

An instance of a sensor on DT-based MMP2 platform is always going to be created asynchronously. Let's move the manual device creation away from the core to the Cafe driver (used on OLPC XO-1, not present in DT) and set up appropriate async matches: I2C on Cafe, FWNODE on MMP (OLPC XO-1.75).
