Even though the CODA h.264 decoder always decodes complete macroblocks, we can set the stride to the corresponding multiple of 16 and use a value smaller than that as real width. Unfortunately the same doesn't work for height, as there is no vertical linesperframe stride for discontiguous planar YUV frames. Signed-off-by:

On i.MX53 and i.MX6, the CODA VPU can be reset by the System Reset Controller. We can use this to get out of dire situations, for example after a picture run timeout. Signed-off-by:

Rename the per-context prescan_failed variable to hold, as this is what the flag does: it temporarily keeps the coda from running until new data is fed into the bitstream buffer or stop_streaming is called on the input side. A prescan failure on i.MX5 is one possible reason to enter this state, another one is a picture run timeout on i.MX6. Signed-off-by:

The coda h.264 decoder also counts PIC_RUNs where no frame was decoded but a frame was rotated out / marked as ready to be displayed. This causes an offset between the incoming encoded frame's sequence number and the decode sequence number returned by the coda. This patch introduces a sequence counter offset variable to keep track of the difference. Signed-off-by:

The coda driver advertises timestamp_type V4L2_BUF_FLAG_TIMESTAMP_COPY on both queues, so we have to copy timestamps from input v4l2 buffers to the corresponding destination v4l2 buffers. Since the h.264 decoder can reorder frames, a timestamp queue is needed to keep track of and assign the correct timestamp to destination buffers. Signed-off-by:

Some drivers might allow to decode remaining frames from an internal ringbuffer after a decoder stop command. Allow those to call v4l2_m2m_try_schedule directly. Signed-off-by:

If the bitrate control is set, the encoder works in CBR mode, dynamically changing the quantization parameters to achieve a constant bitrate. With the min/max QP controls the quantization parameters can be limited to a given range. Signed-off-by:

This adds a new function coda_check_firmware that does the firmware version checks so that this can be done only once from coda_probe instead of every time the runtime pm framework resumes the coda. Signed-off-by:

Using the coda_mutex lock to serialize hardware access would cause "INFO: possible circular locking dependency detected" lockdep warnings. Since the possible locking paths are hard to follow, serialize hardware access with a single workqueue thread. Ultimately the workqueue could be converted to only do register setup and readout for per-command work items. Using the initialized context property, SEQ_END is only queued in coda_release when needed. Signed-off-by:

The h.264 decoder produces capture frames that are a multiple of the macroblock size (16 pixels). To inform userspace about invalid pixel data at the edges, use the active and padded composing rectangles on the capture queue. The cropping information is obtained from the h.264 sequence parameter set. Reviewed-by:

This patch adds support for the CODA960 VPU in Freescale i.MX6 SoCs. It enables h.264 and MPEG4 encoding and decoding support. Besides the usual register shifting, the CODA960 gains frame memory control and GDI registers that are set up for linear mapping right now, needs ENC_PIC_SRC_INDEX to be set beyond the number of internal buffers for some reason, and has subsampling buffers that need to be set up. Also, the work buffer size is increased to 80 KiB. The CODA960 firmware spins if there is not enough input data in the bitstream buffer. To make it continue, buffers need to be copied into the bitstream as soon as they are queued. As the bitstream fifo is written into from two places, it must be protected with a mutex. For that, using a threaded interrupt handler is necessary. Signed-off-by:

For MFC firmwares, improved versions with bug fixes and feature additions are released keeping the firmware version including major and minor number same. The issue came with the release of a new MFCv6 firmware with an interface change. This patch adds the support of accepting multiple firmware binaries for every version with the driver trying to load firmwares starting from latest. This ensures full backward compatibility regardless of which firmware version and kernel version is used. Signed-off-by:

X-Patchwork-Delegate: mchehab@redhat.com Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files. Note that the current (common sense) dependency on SMS_USB_DRV and SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not violate its constraints. These constraint are that: - it should only be built if SMS_USB_DRV is set; - it can't be builtin if USB support is modular. So drop the dependency on SMS_USB_DRV, as it is unneeded.
