Description Ray Strode 2002-08-19 00:34:47 EDT

XFree86 from RawHide doesn't start, failing with the 
error "xf86MapVidMemSparse: Could not (dense) mmap fb (No such file or 
directory)".  This is because mapVidMemSparse() in lnx_video.c incorrectly 
assumes that if mmap() returns an address that is different from the address 
requested then there is an error.

I will attach a patch that seems to fix the problem.

Thanks for the report, and the patch.  When I get a chance to hack
on Alpha stuff, I'll poke at this, and try to integrate changes needed
for Alpha and test, etc.

Thanks again.

Comment 3 Mike A. Harris 2002-11-03 08:19:09 EST

Applied to my 4.2.1-9.1 build, and my latest CVS build as of today.
Patch seems to work fine.  Thanks.
