Maximum memory size allocable with dma_alloc_coherent

Hi,
What is the maximum memory size allocable with dma_alloc_cohernet on jetson nano?

Thanks.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

May I know what the use case tou want to implement?
Is this still an issue to support? Any result can be shared? Thanks
