Created August 22, 2017 15:27
Xilinx kernel module demonstrating kernel<-->PL memory mapped acces with and without caches using kernel asm/io.h primitives
/* CPU <-> PL Communication Example
*
* This small example is designed to show how to communicate between the CPU and the PL
* without using DMA. For some applications the amount of data being transferred may be
* small enough that is quicker to not use DMA.
*
* This example assumes a BRAM is on the PL for the testing at a specific address.
* It includes several test methods, cached and non-cached, to compare the performance.
* There are likely more optimization methods that could be applied as this is not
* intended to be that (such as LDM/STRM). This BRAM is connected to the GP0 and GP1
