Currently the cobalt driver refuses to load if fewer than 8 PCIe lanes are assigned. This patch changes this and just issues a warning. The only time it will refuse to load is if the number of assigned lanes is less than what the PCIe host is capable of since this suggests that the card isn't seated correctly in the slot.

When vb2_is_busy() it should still be possible to call S_DV_TIMINGS provided the new timings are the same as the current timings. For input 1 (test generator) the size is always 1080p, so just return that. Fixes a v4l2-compliance issue. Signed-off-by:

There was a race condition where during cleanup/release operation on-going streaming would cause a kernel panic because the hardware module was disabled prematurely with IRQ still pending.

Add videobuf2 specific vb2_qbuf and vb2_dqbuf trace events that mirror the v4l2_qbuf and v4l2_dqbuf trace events, only they include additional information about queue fill state and are emitted right before the buffer is enqueued in the driver or userspace is woken up. This allows to make sense of the timeline of trace events in combination with others that might be triggered by __enqueue_in_driver. Also two new trace events vb2_buf_queue and vb2_buf_done are added, allowing to trace the handover between videobuf2 framework and driver. Signed-off-by:

The queue owner will be used by videobuf2 trace events to determine and record the device minor number. It is set in v4l2_m2m_reqbufs instead of v4l2_m2m_ioctl_reqbufs because several drivers implement their own vidioc_reqbufs handlers that still call v4l2_m2m_reqbufs directly. Signed-off-by:

Trace events with exactly the same parameters and trace output, such as v4l2_qbuf and v4l2_dqbuf, are supposed to use the DECLARE_EVENT_CLASS and DEFINE_EVENT macros instead of duplicated TRACE_EVENT macro calls. Suggested-by:

The chroma interleaved NV12 format has higher memory bandwidth efficiency because the chroma planes can be read/written with longer burst lengths. Use NV12 as default format if available and consistently sort it first. Signed-off-by:
-
Philipp Zabel authored
Storing internal frames in macroblock tiled order improves memory access patterns by allowing increased burst sizes when transferring the uncompressed macroblocks to or from main memory. The translation logic only supports a single chroma base address, so this is only supported for the chroma interleaved NV12 format. Since the rotator used to copy the decoder output into the v4l2 capture buffers does not seem to support the tiled format correctly, only enable it in the encoder for now. Signed-off-by:

Philipp Zabel authored
The frame cache should be set up correctly to encode NV12 source frames. This was not done before, so move the cache setup out of start_decoding into its own function and call it from both start_encoding and start_decoding. Signed-off-by:

The encoder needs to know the nominal framerate for the constant bitrate control mechanism to work. Currently the only way to set the framerate is by using VIDIOC_S_PARM on the output queue. Signed-off-by:

On i.MX6, sometimes after decoding a stream, encoding will produce macroblock errors caused by missing 8-byte sequences in the output stream. Until the cause for this is found, reset the hardware after sequence end, which seems to help. Signed-off-by:

The v4l2_m2m_num_src_bufs_ready() function is called in multiple places in coda_cob_ready, and there already is a variable src_bufs that is assigned to its result. Move it to the beginning and use it everywhere. Signed-off-by:

Trace events with exactly the same parameters and trace output, such as coda_enc_pic_run and coda_enc_pic_done, are supposed to use the DECLARE_EVENT_CLASS and DEFINE_EVENT macros instead of duplicated TRACE_EVENT macro calls. This patch changes the order of parameters to coda_dec_rot_done and adds a timestamp so it can share an event class with coda_bit_queue. Signed-off-by:

Allow coda_seq_end_work to be called multiple times, move the setting of ctx->initialized from coda_start/stop_streaming() into coda_start_encoding/decoding and coda_seq_end_work, respectively, and skip the SEQ_END command in coda_seq_end_work if the context is already deinitialized before.

This is already done for one side of the comparison with the expectation that the HW counter rolls over at the 16 bit boundary. This is true when decoding a h.264 stream, but doesn't hold for at least MJPEG. As we don't know the exact wrap-around point for this format just clamp the HW counter to the same 16 bits. This should be enough to detect most of the errors and saves us from doing different comparisons based on the decoded format. Signed-off-by:

This commit implements frame decimation for stk1160, which allows to support format changes instead of a static frame size. The stk1160 supports independent row and column decimation, in two different modes: * set a number of rows/columns units to skip for each unit sent. * set a number of rows/columns units to send for each unit skipped. This effectively allows to achieve different frame scaling ratios. The unit number can be set to either two row/columns sent/skipped, or four row/columns sent/skipped. Since the video format (UYVY) has 4-bytes, using a unit number of two row/columns results in frame color 'shifting', so set to four row/columns sent/skipped. Signed-off-by:

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency of VIDEO_ADV7604 and VIDEO_COBALT (the latter selects the former) on GPIOLIB if COMPILE_TEST is enabled. Signed-off-by:

Use the new v4l2_subdev_notify_event() helper function to deliver the resolution change event to userspace via the v4l2 subdev event queue as well as to the bridge driver using the callback notify mechanism. This allows userspace applications to react to changes in resolution. This is useful and often necessary for video pipelines where there is no direct 1-to-1 relationship between the subdevice converter and the video capture device and hence it does not make sense to directly forward the event to the video capture device node.

Add a new helper function called v4l2_subdev_notify_event() which will deliver the specified event to both the v4l2 subdev event queue as well as to the notify callback. The former is typically used by userspace applications to listen to notification events while the later is used by bridge drivers. Combining both into the same function avoids boilerplate code in subdev drivers. Signed-off-by:
