imx-vpu-hantro updates for 4.14 kernel?

[jonathanolson]

The imx-vpu-hantro depends on ION memory allocator APIs which became obsolete after kernel 4.12.

It seems that these kernel APIs were changed after 4.12 to use a dma buffers similar to the V4L2 APIs.

Are there any updates to imx-vpu-hantro to support the new kernel APIs?  I've checked up to the 1.13 release but no joy...

Better yet, I wish NXP would just replace imx-vpu-hantro with support for the V4L2 M2M hantro driver being developed for Rockchip which uses the same hantro codec.

Hello Jonathan Olson,

My apologies for the delay.

There was a customer who successfully replaced the driver solution with the V4L2 implementation from Rockchip.

There are plans for using V4L2 interface for controlling the Hantro VPU, but it will be based on the VeriSilicon driver and we don’t have a public roadmap as of today.

There are no plans for the moment to use DMABUF instead of ION in imx-vpu-hantro.

I hope this helps!

Regards,
