Description Roland Scheidegger 2005-07-05 03:44:48 UTC
zreaddraw doesn't work correctly at least on r200 (independant from tiling, page
flip etc.). Looks related to the renderbuffer code, last date it worked was
20050504 18:00 GMT. It's not completely broken (shortly after that date it was)
but about 4/5 of the area is completely white. Though if you don't force it to
redraw after starting it it's completely hosed.

Kernel .config

bogus zreaddraw screenshot (24bpp). The amount of how much of the picture is
mostly correct is somewhat randomized, i.e. for instance switch to a different
screen and back and it will be different, but at least 2/3 is always white.

only r200 was affected, fixed.

Mass version move, cvs -> git
