I have long thought that linux could be much improved by having
its driver interface just accidentally happen to be identical to
Windows driver interface so you could just "oops" load windows
drivers :-).
Or at least have an optional layer which could install them.
Unfortunately, this would only help (admittedly the majority) folks
with i386 systems. Folks running linux on PPC, etc couldn't take
advantage of such drivers (unless you want to run drivers in
a 386 emulation layer - which might be possible but seems likely
to impact performance just a tad :-).
Umm, an emulated interrupt handler doesn't sound all that good to me.
And I've had to use them, with a PPC emulating a Z8001.
Also, from my brief foray into the early Windows NT Driver Development
Kit, I suspect there are only about 3 sentient entities in the universe
who actually understand how to develop windows drivers, and only one
of them lives within 4 light years of earth :-).
Well, I didn't find the DDK hard to understand, just hard to use. Just
reading the registry and making entries, hooking into the interrupt
structure, reserving memory and I/O space addresses with HAL, and
setting up for the deferred procedure calls took 1500 lines of C.
That was before actually writing any running code, just getting
installed as a driver. And the double conversion from Unicode to ASCII
to C style strings and then back again for everything was a major PITA
as well. Each individual part is easy enough to understand, but
it is all so complicated, and the documentation doesn't lay it all
out in order, just lots of "example code".

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
