Hi all,
just a word to tell that the last gcc-egcs 2.95 seems to be buggy
with the io.
I have a driver for an owner video acquisition PCI card and this one
worked well. Last day I've installed the last
[gcc version gcc-2.95 19990524 (prerelease)]
and then my driver did no more works !
After a lot of debug , I realized that the function 'ioremap' returned
me a valid virt. address but all reading on this remapped io did
0xFFFFFFFF !!
Now I've reinstalled egcs [gcc version egcs-2.90.29 980515 (egcs-1.0.3
release)]
and the same recompilation make the driver working !!!!! with the same
source !!
Also , if you plan to use IO , don't use gcc-2.95 now ( next release
perhaps ... )
