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.

No, this only change only effects g45 chips, which would have been
incorrectly handling the hardware vblank counter. It will have no
impact on 945. I'm trying to pull changes that are definite wins from
my Intel branch right now. I don't think that I have seen the symptoms
that you describe on my 945, except when it is resuming from suspend. I
do only run gnome on it though, it is far too slow to do kde as well...
I'm trying to fix up the interrupt handling in a less invasive way than
I did previously, but even that should only effect 965+ with msi
enabled.
I have not tried GNOME, but mine does work fine with plain old xdm
and twm. It has been happily running for year(s) with previous
Xorg/KDE and drm.
