Add a 1 second timeout for each PIC_RUN command to the CODA. In case it locks up, stop all queues and dequeue remaining buffers. Signed-off-by:

Determining the next free instance just by incrementing and decrementing an instance counter does not work: if there are two instances opened, 0 and 1, and instance 0 is released, the next call to coda_open will create a new instance with index 1, but instance 1 is already in use. Instead, scan a bitfield of active instances to determine the first free instance index. Signed-off-by:

job_ready is supposed to signal whether a context is ready to be added to the job queue, not whether the CODA is ready to run it immediately. Calling v4l2_m2m_job_finish at the end of coda_irq_handler already guarantees that the coda is ready when v4l2-mem2mem eventually tries to run the next queued job. Signed-off-by:

Some codecs running on CODA need internal framebuffers for reference and reconstructed frames. Allocate them separately, and do not use the input vb2_buffers: those will be handed off to userspace regularly, and there is no way to signal to the CODA which of the registered framebuffers are off limits. As a consequence, userspace is now free to choose the number of v4l2 buffers. This patch also includes the code to set up the parameter buffer for CODA7 and above with 64-bit AXI bus width.

This uses the ARCH_MXC specific iram_alloc API to allocate a work buffer in the SoC's on-chip SRAM and sets up the AXI_SRAM_USE register. In the future, the allocation will be converted to use the genalloc API. Signed-off-by:

Add support for loading a raw firmware with 16-bit chars ordered in little-endian 64-bit words, corresponding to the memory access pattern of CODA7 and above: When writing the boot code into the code download register, the chars have to be reordered back. Signed-off-by:

New mem-to-mem video drivers should use V4L2_CAP_VIDEO_M2M capability, rather than ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags, as outlined in commit a1367f1b. Signed-off-by:

Check against q->fileio to see if the queue owner should be set or not. The former check against the return value of read or write is wrong, since read/write can return an error, even if the queue is in streaming mode. For example, EAGAIN when in non-blocking mode. Signed-off-by:

The ioctl validity checks have been improved and now take vfl_type and vfl_dir into account. During the 2012 Media Workshop it was decided that these improved v4l2 core checks should be added as they simplified drivers and made drivers behave consistently. Signed-off-by:

While the documentation says that VIDIOC_CROPCAP is compulsory for all video capture and output devices, in practice VIDIOC_CROPCAP is only implemented for devices that can do cropping and/or scaling. Update the documentation to no longer require VIDIOC_CROPCAP if the driver does not support cropping or scaling or non-square pixels. Signed-off-by:

These have been replaced by new defines without the "CUSTOM_" part. Get rid of the old ones. Signed-off-by:
-
Hans Verkuil authored
The 'custom' timings are no longer just for custom timings, but also for standard CEA/VESA timings. So rename to V4L2_IN/OUT_CAP_DV_TIMINGS. The old define is still kept for backwards compatibility. This decision was taken during the 2012 Media Workshop. Signed-off-by:

Currently the core code looks at tvnorms to see whether ENUMSTD or G_PARM should be enabled. This is not a good check for drivers that support the STD API on one input and the DV Timings API on another. In that case tvnorms may be 0. Instead check whether s_std is present (for ENUMSTD) or whether g_std or current_norm is present for g_parm. Also, in the enumstd core function return ENODATA if tvnorms is 0, because in that case the current input does not support the STD API and ENUMSTD should return ENODATA for that. Signed-off-by:

ENODATA should be returned if the API used for getting, changing, querying or enumerating the current video timings is not supported by the current input or output. This was decided during the 2012 Media Workshop. Signed-off-by:

A number of old drivers still had the experimental tag. Time to remove it.

V4L2_BUF_TYPE_PRIVATE was used in these driver for internal purposes. It turned out though that it wasn't used at all, so it could be removed. I know it was used in the past, but clearly later changes made this obsolete. Signed-off-by:

This buffer type isn't used at all, and since it is effectively undefined what it should do it is deprecated. The define still exists, but any internal support for such buffers is removed. The decisions to deprecate this was taken during the 2012 Media Workshop. Signed-off-by:

- S/TRY_FMT should always succeed, unless an invalid type field is passed in. - TRY_FMT should give the same result as S_FMT, all other things being equal. - ENUMFMT may return different formats for different inputs or outputs. This was decided during the 2012 Media Workshop. Signed-off-by:
