Re: [rtl] hard irq by software?

[Norm Dresner <ndrez@att.net>]

Even if the original questioner (kissg@sztaki.hu) has found a  way around
the problem, I was wrestling with exactly this point a few weeks ago and
gave it up for more traditional debugging techniques, so I'd be very
interested in finding out how to do it.

If it can be done from the kernel, then it's easy enough to do from
user-space (via a ioctl-call) so I think that unless it's really easy we
should focus on a kernel-call.  I don't understand the distinction made in
the question about "do it with the hard interrupt flag disabled or not" and
I'd love to get an explanation of this.
