使用 Debian Linux 的 Sun T2/Niagara 硬件加密加速？

  • 772

我想使用较旧的 T2 机器作为 SSL 重网站的网络服务器。使用 Solaris，可以使用对 SSL 有意义的加密加速。现在我想知道这种加密加速是否曾经移植到 Linux 上？

# cat /etc/debian_version
7.7

# cat /proc/cpuinfo
cpu             : UltraSparc T2 (Niagara2)
fpu             : UltraSparc T2 integrated FPU
pmu             : niagara2
prom            : OBP 4.32.2.b 2010/12/21 20:20
type            : sun4v
ncpus probed    : 64
ncpus active    : 64
D$ parity tl1   : 0
I$ parity tl1   : 0

    我无法停止思考这个问题，所以我安装了另一台带有 Solaris 10 和 pkcs11 补丁的 T2 机器。尽管在 dmesg、openssl 引擎或其他方面没有说明，但 Niagara CPU 的硬件加速似乎已经在 Linux 中实现：
