Description ink 1999-03-09 06:11:02 EST
XF86DGA tries to mmap the PCI-bus physical address (32 bit),
but it's wrong on alphas. We should add dense memory base
address to the PCI-bus offset to get correct mapping.

The patch looks good.  This fix has been applied in RawHide, and will
be made officially available in the next release of Red Hat Linux.
Comment 4 ink 1999-06-30 04:06:59 EDT
Still broken in 6.0...
Quoted from XFree86-
 # the following patch is incomplete..broken..and thus commented out.
 #%patch61 -p1 -b .alphadga
I'm afraid the wrong patch sneaked into srpm,
and I'll send another one later today.
Comment 5 Preston Brown 1999-08-23 13:45:59 EDT
This will be fixed in the forthcoming errata release of 3.3.5.
