Yeah. I need to go look at device drivers. Since I had some spare time
today,I've been mapping
out the call paths to see how the fpu emulation is called and I have been
looking at what might I
ned to do to put it in Fiasco. I am also going to see how mach does it for its
broken fpu
emulator
I ahve been at times studying the Mach, Fiasco, Linux, and GeekOS kernels to
try and learn things.
I quickly learned that looking ath te big picture is slow so thats why O have
been looking at the
FPU emulator. I think it has helped some seeing how the entry's and the traps
and all work.
Thanks for the ti[ps. I'll have to go look at OsKit. I can't wait till I know
enough to be of
use to thios project
