2.6.5-rc2-mm[34] causes drop in DRI FPS

2.6.5-rc2-mm[34] causes drop in DRI FPS

[Glenn Johnson]

The last two iterations of -mm kernels have caused my FPS count via
glxgears to drop from about 2000 fps to about 180 fps. I rebuilt X11 to
see if that would help but it did not.

This is with a Radeon 9100 AGP card and an Intel 865PE based
motherboard.

It could be the AGP changes.  Please do a `patch -p1 -R' of
bk-agpgart.patch and retest?

I reverted that patch and retested but it did not solve the problem. I
am still only seeing about 180 fps with glxgears.

what does 'glxinfo | grep rendering' show?

It shows:

        direct rendering: Yes
        
I had checked that first thing. I also verified that the AGPgart
detected the chipset, etc. Everything seems okay in the XFree86 log file
as well.

what about reverting "DRM-cvs-update.patch"?

I just did a diff of my XFree86 log files with the system booted using
the 2.6.5-rc2-mm2 and 2.6.5-rc2-mm4 kernels, respectively. Here is the
diff, so maybe this will mean something.

I have not tried that but has that patch been in the tree for some time
now? My DRI works fine with 2.6.5-rc2-mm2, which has that patch.

That's just a memory allocation, so that will never be consistent.

You're not using CONFIG_PCI_USE_VECTOR in the newer kernel, but that also
wouldn't make a difference.

Actually, I am using CONFIG_PCI_USE_VECTOR in both.
