New Revision: 194540
URL: http://svn.freebsd.org/changeset/base/194540
Log:
The G45 docs indicate that all G4X chips use the new framecount
register.
Intel agrees with my reading of the docs, make it so for all G4X chips.
The new register also has a 32 bit width as opposed to 24 bits. Fix
things up so that the counters roll over properly.
Could this possibly fix the problem I'm seeing with the screen being
garbage after a logout from KDE 3.x (using kdm)? Everything works
fine after logging in, but when you log out, the screen is left with
garbage/lots of vertical striping. This only happened after upgrading
my system (and all ports) to Xorg 7.4, worked just fine before that.

I had similar symptoms. In my case this was cause X server crashing?
Do you see the same. If yes, there might be a recipe for cure.
Possibly, I don't recall if the X server crashed after logout.
Ctrl-Alt-F1, then Ctrl-Alt-Del to reboot was the only way to
recover, sometimes a hard reset was required. I guess I'll
have to try this change to see if it resolves my problem.
