one question happened when compiled code

[wangzhl-code]

hi, i compiled your driver source code in xdma file, but there is a error:
error: implicit declaration of function ‘mmiowb’ [-Werror=implicit-function-declaration]
636 | mmiowb();
why, could you please teach me how to settle it

I also encountered the same issue. Maybe you can comment mmiowb(); to settle it.

You can try the official Xilinx driver https://github.com/Xilinx/dma_ip_drivers
