JetPack 3.3.4 ( L4T 28.5) : CMA support in kernel

Hello,

My FPGA does not support scatter gather. Only DMA to contiguous physical memory (>4MB)
I’m using TX2 on a customized carrier.

Can you please tell if the kernel included in 3.3.4 supports CMA ?
I’m aware that I will probably have to recompile the kernel with CMA=y, DMA_CMA=y

Thank you,
Zvika

Hello,

I checked. CMA is included in the image 64MB

Thank you,
