这里面其实最重要的就是做了两件事,一件事是register_blkdev,注册nvme这类块设备,返回一个major,另一件事是注册了nvme_driver,注册了nvme_driver后,当有nvme设备插入后系统后,系统会自动调用nvme_driver->nvme_probe去初始化这个nvme设备.这时候可能会有疑问,系统是如何知道插入的设备是nvme设备的呢,注意看struct ...
首先我们得组包nvme_cmd,这个包为读命令它包含我们读地址(0x02000000)、长度(nblock = 2)、和读到什么地方(prp);然后把这个包扔给sq,写doorbell通知控制器来数据咯,控制器取出命令来转换为TLP包通过PCIe Memory方式把0x02000000的数据写入到0x10000000中,然后在Cq的尾部写入完成标志,再写doorbell告诉控制器我的事...
本篇文章非常全面的介绍了基于linux5.0的nvme驱动的所有函数,基本每个函数都有非常详细的注释。同时,本篇文章全部是代码+注释的方式呈现,非常的清晰易懂。希望大家加一个关注,下一篇文章详细讲解nvme驱动中的各个结构体//一、nvme_probe介绍 static int nvme_probe(...
