OpenBSD/octeon on the EdgeRouter Lite

· OpenBSD

I've had the EdgeRouter Lite from Ubiquiti since a little more than a year now, and it's a nice and affordable little fanless device to run OpenBSD/octeon on.

The CPU on this machine is a dual-core Cavium Octeon CN50xx (MIPS64 ISA) which can run in both BE and LE modes. OpenBSD runs in big-endian mode on this architecture.

On the minus side, there is no internal clock and no FPU.

Here is the output of running file on executables:

ELF 64-bit MSB shared object, MIPS, MIPS-III version 1

And this is the result of the md5 -t benchmark:

MD5 time trial.  Processing 10000 10000-byte blocks...
Digest = 52e5f9c9e6f656f3e1800dfa5579d089
Time   = 2.183314 seconds
Speed  = 45801932.291920 bytes/second

For the record, LibreSSL speed benchmark results are available here.
