NetBSD kernel's HD Audio sound driver has interrupt handler. The interrupt handler of the demo is re-written by Haskell language using Ajhc Haskell Compiler [ Ссылка ].

At the demo, run following operations.
First, set breakpoint at the interrupt of finding headphone,
and see Haskell function names on backtrace.
Second, set breakpoint s_alloc() function, that allocate area
in Haskell heap. Make sure of calling the function while anytime
running kernel.
Nevertheless, playing wav file does not break up.

The source code is found at [ Ссылка ]. The interrupt handler source code at [ Ссылка ]. A picture of the architecture is also at [ Ссылка ].
