Hi all,
This patch series adds support for
the amphion video encoder and decoder
via the VPU block present in imx8q platforms.
Currently, support for IMX8QXP and IMX8QM is included.
It features decoding for the following formats:
- H.264
- HEVC
- MPEG4
- MPEG2
- VC1
- VP8
It features encoding for the following formats:
- H.264
The driver creates a separate device node for the encoder and decoder.
This driver is dependent on vpu firmwares.
The firmwares have been submitted to linux-firmware.
The firmware patch is since commit
b563148fd28623f6b6ce68bb06c3dd3bd138b058:
linux-firmware: Update firmware file for Intel Bluetooth 9462
(Fri Oct 8 16:30:14 2021 +0530)

amphion: add VPU firmwares for NXP i.MX8Q SoCs
(Tue Oct 12 15:09:57 2021 +0800)
encoder is tested with gstreamer
decoder is tested with gstreamer, but the following patches are required:

- add some documentation descriptions
- pass the lateset v4l2-compliance test
v4:
- redefine the memory-region in devicetree bindings documentation
- use v4l2's mechanism to implement synchronize queuing ioctl
- remove the unnecessary mutex ioctl_sync
- don't notify source change event if the parameters are same as previously established
- add flag V4L2_FMT_FLAG_DYN_RESOLUTION to decoder's capture format
v3:
- don't make vpu device node a simple-bus

2.33.0
The amphion vpu codec ip contains encoder and decoder.
Windsor is the encoder, it supports to encode H.264.
Malone is the decoder, it features a powerful
video processing unit able to decode many foramts,
such as H.264, HEVC, and other foramts.
This Driver is for this IP that is based on the v4l2 mem2mem framework.
Supported SoCs are: IMX8QXP, IMX8QM

2.33.0
driver use mailbox to communicate with vpu core.
and there are a command buffer and a message buffer.
driver will write commands to the command buffer,
then trigger a vpu core interrupt
vpu core will write messages to the message buffer,
then trigger a cpu interrupt.

The vpu supports encoder and decoder.
it needs mu core to handle it.
core will run either encoder or decoder firmware.
This driver is for support the vpu core.

Yes, it means "vpu core", we often call it mu internally.

pixel -> pixels (note: also wrong in the text V4L2_PIX_FMT_NV12_4L4/16L16/32L32)
Shouldn't this be called V4L2_PIX_FMT_NV12M_8L128? The 'MT' suffix seems to be specific
to macroblock tiles and not linear tiles.

at the big end -> in big endian order
I assume the 10 bit pixels are packed? So 5 bytes contain 4 10-bit pixels layout like
this (for luma):
byte 0: Y0(bits 9-2)
byte 1: Y0(bits 1-0) Y1(bits 9-4)
byte 2: Y1(bits 3-0) Y2(bits 9-6)
byte 3: Y2(bits 5-0) Y3(bits 9-8)
byte 4: Y3(bits 7-0)

Either do:

return -EINVAL;
or just drop it. You'll get a oops with backtrace soon enough.

Use pm_runtime_resume_and_get() instead and drop the pm_runtime_put_noidle()
in the 'if' below. The use of pm_runtime_resume_and_get is preferred over
the rather confusing pm_runtime_get_sync().
If it is used elsewhere in this series as well (I haven't checked this),
then make the same changes.

I would drop VB2_USERPTR. Not desired for new drivers unless there is a really good reason.

Assuming this means the minimum number of buffers needed, why is
min_buffers_needed set to 1 when initializing the vb2_queue structs?

This looks very wrong. I expect a call to v4l2_m2m_ctx_release() here,
and that will take care of any streaming.

In my opinion, the min_buffers_needed determine when vb2_start_streaming will be called,
Like the following code:
if (q->queued_count >= q->min_buffers_needed) {
... ...
ret = vb2_start_streaming(q);
... ...
}
I hope driver starts a vpu instance when 1 frame is queued, so I set the min_buffers_needed to 1.
And the min_buffer_cap means the minimum vb2 buffer count, and it will changed according to the stream,
I just set default value to 2, it will be changed after vpu parsed the stream info.

As discussed earlier, when producing tiled, this driver should negotiate
V4L2_FIELD_ALTERNATE and ensure the sequence numbers for paired fields matches
as per spec. The height being halved is common this this type of interlace
output.
Note that this is a bit of a whole in GStreamer fluster integration (there is
nothing to merge fields), you can probably just move NV12, which according to
its frame size will be interleaved, by placing that format first in your
enum_fmt implementation. Though it conflict with the intent to place first the
most "native" format. I can also provide patch that will force NV12 in fluster
for current mainline testing.

As a followup, this should be conditional to the chosen pixel format. If I
understood correct, you produce interlaced is only produce for linear NV12, for
tiled the fields are outputed seperated in their respective v4l2_buffer. Note
sure where yet, but the V4L2 spec requires you to pair the fields by using the
same seq_num on both.

The amphion vpu will store the two fields into one v4l2_buf,
So I'll change V4L2_FIELD_INTERLACED to V4L2_FIELD_SEQ_TB

Hi Nicolas,
Seems gstreamer doesn't support V4L2_FIELD_SEQ_TB yet.
switch (fmt.fmt.pix.field) {
case V4L2_FIELD_ANY:
case V4L2_FIELD_NONE:
interlace_mode = GST_VIDEO_INTERLACE_MODE_PROGRESSIVE;
break;
case V4L2_FIELD_INTERLACED:
case V4L2_FIELD_INTERLACED_TB:

interlace_mode = GST_VIDEO_INTERLACE_MODE_INTERLEAVED;
break;
case V4L2_FIELD_ALTERNATE:
interlace_mode = GST_VIDEO_INTERLACE_MODE_ALTERNATE;
break;
default:
goto unsupported_field;

This is correct, I had never had the chance to implement it. So far I only know
IMX6 camera pipeline producing that, but rarely used in practice. What matters
here is that your driver does report the right information so that userspace
don't get fooled into thinking it's interleaved.
