[9fans] Experiments in the wild

[lu...@proxima.alt.za]

I have a MikroTik 411 that will soon be deployed as a Wi-Fi link to
the Internet and in the absence of any other manner to mess with it
until then, I decided to see how far a Plan 9 installation would go:


Plan 9
cpu0: 680MHz mips 24k be v3.5 rev 0, no fpu
cpu0: 16 tlb entries, using 4K pages
cpu0: l1 i cache: 512 sets 4 ways 32 bytes/line
cpu0: l1 d cache: 256 sets 4 ways 32 bytes/linecaches configured as write-through
256M memory: 53M kernel data, 203M user, 1227M swap
#l0: atheros71xx: 1Gbps port 0X1A000000 irq 5: d4ca6d7df1ce
#l1: atheros71xx: 1Gbps port 0X19000000 irq 4: d4ca6d7df1cf

It stops there, but there are enough lies in the above to accept that
verdict.

Still, it shows promise, given that this is 9rb created from the
distribution. I don't think I have the know-how to fix it (I may do
at least some digging, though), but I thought others may find this at
least interesting.

In passing, having to build the user space for MIPS, I found that it
helps if /mips/bin/contrib is writable by the builder: it is not
created by default, but it comes in handy for those of us who may have
something that will be installed in it.

Make sure you have modified vl nop.c to emit the anti triple store bit and make sure that there is a proper root. I had a machine hang just like that this week.

I vaguely remember mention of the problem with three consecutive store
operations, I'm not sure how to make sure there is a proper root, but
I suspect that I can look that up. But fixing the memory size (the
411 has only 32MiB) and other strange items (two ethernet ports? I
would not expect the Wi-Fi to present itself as an ethernet device)
may be another problem altogether.

Still, I'll give it a shot.
