Subject: Make sure texture base addresses are used correctly.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a5fb15cb87a0734f5e0bf1b1dafe5204a32052da;p=mesa.git

Make sure texture base addresses are used correctly.

They are relative to the card's address space, not relative to fbLocation,
which will be important once we program MC_FB/AGP_LOCATION in the way
they are programmed on older Radeon chips.
