[9fans] plan9-bcm GPIO control raspberry pi

So I ran across this ( https://github.com/elewarr/plan9-bcm ) awhile back
and decided it would be fun to try to stick it on my pi running 9front.
Problem is I'm either too new to this, or am missing something really basic
when I'm trying to compile the kernel. Normally iirc one just has to run
"mk install" and things tend to come together, but I'm getting an error "No
recipe to make 'fpi.5' in director /sys/src/9/9-bcm"

I realize that the 5 corresponds to the ARM arch and I assume it is
supposed to be made automatically, I'm not sure if tehre's some
documentation somewhere on this I missed or if I should just dig through
the source to find out what it is/should be.

Thoughts?

just did a mk in /sys/src/9/bcm and it builds just fine.

what is "/sys/src/9/9-bcm"?

i'm guessing that plan9-bcm source directory should be bound -- bind(1) --
to /sys/src/9/9-bcm (or even /sys/src/9/bcm).

Ok, it ran when bound to /sys/src/9/bcm. Flawless success. @cinap_lenrek,
the folder was the source for the bcm kernel thing I linked above, it's
built to support GPIO afaik, I'd like to play with GPIO whilst I learn
plan9 on this pi.

If I may ask, what is the reason that it ran when bound to bcm, permissions
or something?
