It turns out that received CEC messages can arrive faster than can be processed by the CEC framework, resulting in lost messages. Instead of storing only one CEC message, store up to 8. Also fix a bug where the EOM bit wasn't checked for a received message of length 1, so POLL messages weren't properly reported. Signed-off-by:

Instead of adap_transmit waiting until the full message is transmitted (and thus hoarding the adap->lock mutex), have it kick off a transmit workqueue. This prevents adap->lock from being locked for a very long time. Also skip FAILED_ACK reports for broadcast messages: this makes no sense, and it seems a spurious message coming from the Pulse-Eight, since some time later I see the SUCCEEDED message.

Drop the write_lock, rename config_lock to plain lock since this now locks access to the adapter. Use 'lock' when transmitting a message, ensuring that nothing interferes with the transmit. Signed-off-by:

When building with Clang + -Wtautological-constant-compare, several of the ivtv and cx18 drivers warn along the lines of: drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the result of '<<' to a boolean always evaluates to true [-Wtautological-constant-compare] cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL, ^ drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro 'CX18_HW_GPIO_RESET_CTRL' #define CX18_HW_GPIO_RESET_CTRL (1 << 6) ^ 1 warning generated. This warning happens because the shift operation is implicitly converted to a boolean in v4l2_device_mask_call_all before being negated. This can be solved by just comparing the mask result to 0 explicitly so that there is no boolean conversion. The ultimate goal is to enable -Wtautological-compare globally because there are several subwarnings that would be helpful to have. For visual consistency and avoidance of these warnings in the future, all of the implicitly boolean conversions in the v4l2_device macros are converted to explicit ones as well.

The Hantro G1 decoder is able to enable a post-processor on the decoding pipeline, which can be used to perform scaling and color conversion. The post-processor is integrated to the decoder, and it's possible to use it in a way that is completely transparent to the user. This commit enables color conversion via post-processing, which means the driver now exposes YUV packed, in addition to NV12. Signed-off-by:

It has been decided to use the ENUM_FMT index value as a hint for driver preference. This is defined purposedly in a very liberal way, letting drivers define what "preference" means. For instance, the Hantro VPU driver indicates additional processing to output a given format, and thus implicates more CPU usage, which is enumerated after native (non-processed) formats.

Add support for the sink pad of scaler subdevice to respond VIDIOC_G_SELECTION and VIDIOC_S_SELECTION ioctls with the following targets: V4L2_SEL_TGT_COMPOSE_BOUNDS and V4L2_SEL_TGT_CROP. * Add new const struct crop_rect_default to initialize subdev scaler properly. * Make changes in sink pad format reflect to the crop rectangle. E.g. changing the frame format to a smaller size one can make the former crop rectangle selects a non existing frame area. To solve this situation the crop rectangle is clamped to the frame boundaries. * Clamp crop rectangle respecting the sink bounds during set_selection ioctl. Co-developed-by:

When requesting format from sensor, some sensors call the subdev_get_try_crop which for ISI was not properly initialized, and this causes errors in determining proper image resolutions. To accommodate for this, when trying a format (in try_fmt), first attempt to obtain the framesize for this format from sensor. In case this fails, use the maximum ISI width/height as try_crop, otherwise provide the first size height/width from the sensor. Signed-off-by:

This adds support for GREY and Y16 formats, based on Y10 mbus codes. Y16 needs to go through preview path in the ISI, with 2 pixels per word, and it fits the Y16 format. The ISI data lines need to be MSB aligned with the sensor data lines. GREY format in 8 bits per pixel is done by dropping the 2 LSB bits from the Y10 format, and packed as 4 pixels per word.

The ISC can receive input from sensors using Y10 format directly (10 bits greyscale). In this case, the ISC must dump the data directly, either as GREY (8bit) or Y10 (10bit). Y16 is not supported because we cannot align the MSB 10 bits to the MSB inside the 16bit container. For this format, the ISC internal pipeline cannot work (only works with BAYER), so we must dump the data directly as 8bit/10bit. Signed-off-by:

In case the format that the sensor sends is 8 bit only (like GREY for example) we need to be able to bypass ISC pipeline and directly dump 8 bits. That's why the hardcoded value of 16 bpp is not correct in all cases. This change allows the output format to decide what is the correct bpp (bits per pixel) such that the result is in the proper format. Signed-off-by:

When decoding using the CODA internal rotator (for example NV12 capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19) is written into the DEC_PIC_ROT_INDEX register. At least with firmware version 3.1.1 this causes CODA hangups as soon as the register value reaches 32. Instead, always write CODA_MAX_FRAMEBUFFERS. Signed-off-by:

This patch adds JPEG encoding support for CODA960, handling the JPEG hardware directly. A separate JPEG encoder video device is created due to the separate hardware unit and different supported pixel formats. While the hardware can not change subsampling on the fly, it can encode 4:2:2 subsampled images into JPEGs of the same subsampling. There are two additional tracepoints added to the coda driver that can be used together with the v4l2:v4l2_qbuf and v4l2:v4l2_dqbuf tracepoints to to follow video frames through the mem2mem device when encoding or decoding with the CODA960 JPEG codec: coda:coda_jpeg_run coda:coda_jpeg_done Signed-off-by:Richard Leitner <richard.leitner@skidata.com> [hverkuil-cisco@xs4all.nl: removed unused k and q_data_dst variables] Signed-off-by:
