We are working on a project using AlphaData board connected to Xavier’s PCIe slot. But PCIe DMA read and write rates are only 200+MBps. The Xavier’s L4T version is 3.5.1.
I also noticed there is an issue that the earlier version of kernel (32.2.1?) doesn’t support “PCIe Asynchronous DMA”. I’m not sure if it is the problem.
I was wondering which version of kernel start to support Asynchronous DMA? and should I configure to enable it?
