Plan 9 runs on the various Raspberry Pi models. The port is stable
and performs reasonably, but there is more work to be done.
TODO
The Raspberry Pi contains a lot of interesting bits that we aren't
yet doing anything with. Here's a (more or less complete) list of
things we'd like to see done, with some info on each.
The best starting point for an [overview of the Pi's hardware
capabilities | http://elinux.org/RPi_Low-level_peripherals] is on
their wiki.
* [GPIO |
http://elinux.org/RPi_Low-level_peripherals#General_Purpose_Input.2FOutput_.28GPIO.29]
Bakul Shah has been working on a GPIO driver for the Pi.
* I²C
* I²S
* audio
* pwm
* spi
* [DSI | http://www.mipi.org/specifications/display-interface] &
[CSI-2 | http://www.mipi.org/specifications/camera-interface]
These are display and camera interfaces, located at S2 and S5 on the
Pi, respectively. These are not widely supported on the various
systems which run on the Pi, and compatible hardware is not very
common. Compatible displays can be found in some smartphones.
