nVidia driver acceleration engine non-functional error located!

Hi there,

I've traced the versions where it went wrong:
r24493 is working OK;
r24511 is faulty.

It's MTRR-WC failed mapping because of overlapping regions after all:
commenting out the change in the kernel done in r24494 fixes the problem.
I'm now running r24865 in 32bit accelerated mode on my NV15.

I don't know what is the first mapped region that is later on overlapped
by my driver's request, but that deserves to be investigated. If that's
legal then overlapping regions may not be blocked I'd say!

Can someone have a look at this????

Bye!

Rudolf.


PS: I'm posting this finding in ticket #1950 and #2071 as well.
More tickets will exist.
