Subject: Re: [PATCH v9 00/13] amphion video decoder/encoder driver
Hi Ming,

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:
https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.9.bin
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.

Nicolas
