imx8mmini evk missing ion allocator for hantro vpu on debian

[simon_friedrich]

Hello community,

I use the imx8mmini evk and try to compile the hantro vpu librarys for debian with kernel version 4.19.35_1.1.0. I have a running debian system and compiled the kernel for it as well.

Within the yocto project recipes I found the sources for the imx-hantro-vpu and tried to compile on my debian system, but it seems I am missing the ion allocator.

At first i thought it might be a missing kernel option and tried different options(especially because i found the missing header file within the kernel sources) but none of them worked for me. Right now I think it must be a mssing package which is installing the ion allocator.

Does anyone know which package/recipe I need to make the ion allocator available and where to find?

Best regards,

Simon F.

the configure file enable this option:

"CONFIG_ION_CMA_HEAP=y"
defconfig\configs\arm64\arch - linux-imx - i.MX Linux kernel

Hi Joan,

thanks for the reply. I checked this config option and it is enabled by default. Are there any other options I may miss, because this doesn't solve my problem.

Best regards
