We are using AR65444 PCIe driver for linux , and we would like to understand why 4K posix_memalign is required, what is the reason for it ?
Thank you in advanced.

I want to know the reason of the memory allocation with 4K alignment in userspace application demo (tools/dma_from_device.c) as below.
posix_memalign((void **)&allocated, 4096 /*alignment */ , size + 4096);
