近来由于Windows update频繁占用2Mb小水管的VPN带宽,不得不研究对策解决问题。要么是自己架双线双拨的路由,自己设置路由规则;要么就是找出Windows update的对方服务器,将其从VPN列表里踢出去。VPN供应商说,他们所用的思科设备无法通过域名的方式白名单,只能一个个加IP。怒骂W......

SMx内核驱动开发笔记
- 背景
硬件背景
为SMx开发Linux驱动。
SMx为与ARMv8核心以AXI和AHB挂接的SoC内部模块,用于SM3/4加速。
SMx功能包括SM3,SM4-ECB/CBC/CTR/CFB/OFB/GCM计算。
含有内部自用DMA,以及与SPAcc相似的内部连线接口。
软件背景
目标系统Peta Linux, kernel 4.6, ......
由于内核驱动运行于内核空间,而Linux的crypto API本身并不推荐开放给用户空间调用,如果要测试该驱动,理论上的办法是在内核里再写一个模块,像kernel自带的tcrypt那样,insmod这个新模块,用类似modprobe tcrypt sec=1 mode=200的方式测试。然而这个方法对于需要大量调用固定测试向量的testbench非常不友好,于是还是寻求从用户空间自由自在编写测试框......
