request: kernel module and devices for epiphany access

[Gravis]

after a look, i realized there is no kernel module for the epiphany chip and that access to the epiphany is all through /dev/mem via e-lib.

my request is to create a kernel module with accompanying devices /dev/epiphany/raw, /dev/epiphany/core0 through core15 (or 63 as the case may be). to sweeten the deal, you could have /dev/epiphany/config for simplified configuration and commands like telling every core to halt/reset/activate/etc and maybe a novel IO like /dev/epiphany/stdio for simplified io for stuff like keyboard and text returned from the epiphany. it just seems like it would make interfacing and debugging. you could dump each core or replace what's there with ease.

you can do plenty of stuff through e-lib/e-hal but a simplified interface sure would be nice.

A kernel module is on the cards, but wouldn't it make more sense to integrate configuration via the /sys filesystem? Perhaps with a /proc/epiphanyinfo also for reading capabilities.

Cheers,

Andrew

A simple /dev interface is more portable between different OS.
