Native Xorg on sparc64

[Michael <macallan%netbsd.org@localhost>]

Hello,

in the last few days I committed the missing bits&pieces needed to run  
native Xorg on sparc64.
All you need to do is setenv MKXORG yes and build.sh distribution. Do  
NOT specify -x or -X.
SBus support is present but untested and nor useful since no SBus or  
UPA drivers have been imported yet ( I think I'll do sunffb and suncg6  
in the near future ). The Xserver will detect SBus and UPA carts  
( even though it thinks my FFBs are AFBs ) but won't be able to use  
them for lack of drivers.
PCI drivers should work but the only one I tested so far is radeon  
( with an XVR-100 ) - it works fine, although monitor configuration is  
rather different than in XFree86 ( you HAVE TO specify a Monitor  
section for each of the radeon's outputs, just putting it into the  
Screen section isn't enough and won't work right )
The mach64 driver should work out of the box ( would be nice if anyone  
could confirm that ), glint probably won't ( XFree's needed a simple  
change to work on BE hardware, I suspect Xorg's needs it too ).

The wsfb driver is included, should work as before but it's completely  
untested so far.

It should also build on sparc but for the lack of sbus drivers it's of  
limited use. Wsfb should work though.

have fun
Michael
