Subject: fast interrupts?
Date: Sat, 8 Jun 2002 05:11:01 -0400	[thread overview]
Message-ID: <046701c20ecc$69f3d560$9e03a5d8@oemcomputer> (raw)

Hi,
I am new both to this list and linux and i need help. have started reading
the book by Michael Beck...
am not clear about register saving in fast interrupts...
the book says...
while handling a fast interrupt, only those registers are saved that are
modified by a normal C function (?). This means that , if assmbler code is
to be used in the handling routine, the remaining registers (?) must be
saved beforehand and restored afterwards.

what does the author mean by registers modified by a normal C function, and
the remaining registers?
