重新make编译DE5a-NET-DDR4的 PCIe driver的时候报错

'''Q''':客户的环境 ubuntu18.04，内核版本5.4.0-150-generic，重新make编译DE5a-NET-DDR4的 PCIe driver的时候报错如下：

'''


'''A'''：内核版本高了  之前的驱动不支持5.4以上的内核版本，

修改方式：
1.将altera_pcie.c中，access_ok函数中的，第一个参数(VERIFY_READ或者VERIFY_WRITE)都拿掉
2.修改Makefile，添加：
        EXTRA_FLAGS += -Wno-error=date-time
        EXTRA_CFLAGS += -Wno-date-time -I$(PWD)

具体参考下面两个截图：

[[File:makeDE5A-NETDDR4PCIE1.jpg]]

[[File:makeDE5A-NETDDR4PCIE2.jpg]]


然后重启再安装。

若重启再遇到问题可以尝试改用modprobe 安装驱动。
