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.
I've been trying to test this driver, based it on mainline 5.15-rc2
in absence of recommendation here. There seems to be poor mainline
support for this board, notably only 1 CPU come up. Finally, I could
not test anything as the driver failed to boot the decoders and
encoder cores:

[   30.766160] [VPU CORE][0] decoder boot
[   31.873175] [VPU CORE][0] decoder boot timeout
[   31.878057] [VPU V4L2]there is no core for decoder
[ 1766.495963] [VPU CORE][1] encoder boot [ 1767.524957] [VPU
CORE][1] encoder boot timeout [ 1767.529724] [VPU V4L2]there is no
core for encoder

Please, let me know how I can get passed these issues. I have used
firmwares referenced in Yocto tree:

Firmware for this driver will also be a subject to tackle. In an
ideal world, the "self extracted" script requirement to accept your
EULA would need to be waved, and distribution of the firmware should
go into linux-firmwares. I believe firmwares are still allowed to
have some user agreement, but I suppose there must be guidelines,
best is to ask there directly.

regards,
Nicolas
Seems you use the wrong firmware, I will send the firmware to you.
My commit base is 9c3a0f285248899dfa81585bc5d5bc9ebdb8fead,
You can find it in the bottom of this cover.

Would you please explain the linux-firmware issue in detail
I believe that to merge a driver (non staging) that depends on a firmware (I'll
let Hans and others confirm), you need to submit this firmware, along with a
non-interactive licence to be included in the linux-firmware project.

NXP notably have an SDMA firmware in there, with a licence file. Perhaps
these developers can assist in this regard. Often that takes time due to legal
requirement of moving from an interactive EULA to a licence file.

In later version, it would be nice to explain in the cover later the status of
firmware distribution, and how to obtain the correct version of (specially if not
yet in linux-firmware).

Thanks for sending me the firmwares, I will see if I can do more tests.
Thank you for the detailed explanation, I'll check the Linux firmware

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.
