This commit adds the needed boilerplate code to support the VPU in decoding operation. Two v4l2 interfaces are exposed, one for encoding and one for decoding, but a single m2m device is shared by them, so jobs are properly serialized. Signed-off-by:

The code in rockchip_vpu_v4l2 was hardcoded for encoder support. Modify it more generic to support the decoder case so that we can re-use the same vb2/v4l2 ops for both devices. Co-developed-by:

When initializing a context, the core wants to reset both src and dst formats. Right now the order doesn't matter, but if we want to have a valid default width/height on the non-coded/raw format side (src in case of encoders, dst in case of decoders), we need to reset those formats in the right order: first the coded-format side, then the other, such that width and height on the raw format side can be taken from the coded format. Let's provide a helper that will reset both formats and make sure this is done in the right order. Signed-off-by:

The V4L2/VB2 implementation for the encoder and decoder logic are very similar, so let's rename rockchip_vpu_enc.c file into rockchip_vpu_v4l2.c and remove the _enc_ part in objects/functions exposed in rockchip_vpu_v4l2.h. We also rename the enc_queue_init() function (in rockchip_vpu_drv.c) queue_init() since it will be used to initialize both type of queues. The implementation itself will be patched to support the decoding case when decoder support is added. Suggested-by:

We're about to add prototypes for the vb2/v4l2 helpers shared by the encoder/decoder logic in this file, so let's pick a name that reflects that (rockchip_vpu_common.h was a bit to generic). Suggested-by:

Introduce support for the Request API. Although the JPEG encoder does not mandate using the Request API, it's perfectly possible to use it, if the application wants to. Signed-off-by:

In preparation to support decoders, using a single memory-to-memory device, we need to roll our own media controller entities registration. To do that, we define a rockchip_vpu_func object that embeds the video_device object plus all the elements that are needed to attach this vdev to the media device. Signed-off-by:

The rockchip VPU driver is open-coding this logic which seems pretty generic. Let's provide an helper to apply the min/max and alignment constraints on width/height. Signed-off-by:

In vb2_vmalloc_get_userptr() the framevector is created with the 'write' argument set to false when vb2_create_framevec() is called for OUTPUT buffers. So the pages are marked as read-only. However, userspace will write to these buffers since it will fill in the data to output. Since get_userptr is only called if the userptr of the queued buffer has changed since the last time that same buffer was queued, this will fail when the buffer contents is updated and the buffer is queued again. E.g., userspace fills buffer 1 with the output video and queues it. The first time get_userptr is called and the pages are grabbed and pinned in memory and marked read-only. The second time buffer 1 is filled with different video data and queued again. Since the userptr hasn't changed the get_userptr() callback isn't called again. Since the pages were marked as read-only the new contents isn't updated. Just always call vb2_create_framevec() with FOLL_WRITE to always allow writing to the buffers. Using USERPTR streaming with OUTPUT devices is almost never done. And when it is done it is via v4l2-compliance and a driver like vim2m. But since v4l2-compliance doesn't actually inspect the capture buffer and compare it to the original output buffer, this issue was never noticed. But the vicodec driver actually needs to parse the bitstream in the OUTPUT buffers and any errors there will be immediately noticed. So this time v4l2-compliance failed the USERPTR streaming test.

The allegro hardware encoder does not write SPS/PPS nal units into the encoded video stream. Therefore, we need to write the units in software. The implementation follows Rec. ITU-T H.264 (04/2017) to allow to convert between a C struct and the RBSP representation of the SPS and PPS nal units. The allegro driver writes the nal units into the v4l2 capture buffer in front of the actual video data which is written at an offset by the IP core. The remaining gap is filled with a filler nal unit.

Add a V4L2 mem-to-mem driver for Allegro DVT video IP cores as found in the EV family of the Xilinx ZynqMP SoC. The Zynq UltraScale+ Device Technical Reference Manual uses the term VCU (Video Codec Unit) for the encoder, decoder and system integration block. This driver takes care of interacting with the MicroBlaze MCU that controls the actual IP cores. The IP cores and MCU are integrated in the FPGA. The xlnx_vcu driver is responsible for configuring the clocks and providing information about the codec configuration. The driver currently only supports the H.264 video encoder. Signed-off-by:
