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. regards, Nicolas > > It features decoding for the following
