Notification about software-fallbacks?

[Clemens Eisserer]

Hi,

I've recently profiled some xrender stuff I've written on R200 class hardware,
and according to sysprof almost the entire time is spent somewhere in pixmap.

Is there a way to get some information why and when software fallbacks
are in action?
Something like the "DebugFallback" option the intel driver has.

Thank you in advance, Clemens
