Linux device drivers in Ada?

Linux device drivers in Ada?

[Brian Drummond]

Possibly a long shot, but does anyone know of any example Linux device
drivers written in Ada? Is it even possible for Linux?

I'm not looking for anything specific, rather for a starting point.
I need to write a device driver for an FPGA card on the PCIe bus, and
I'd rather not use C if at all possible.

It is definitely possible.  The primitive way to do it is to compile
it using GNAT and Pragma (No_Runtime).  I think I've read a
description of a more elegant solution.  You might also want to take a
look at RTL-GNAT (see <http://rtportal.upv.es/apps/rtl-gnat/>).

There is an example in "The Big Online Book of Linux Ada Programming" [1]. 
Lookup chapter 16.16 "Writing Linux Modules".

Thanks! This looks very useful.

Thanks also to Jacob; RTLGnat may not help with the driver per se, but
certainly will with handling modules.
