Description Eric Anholt 2006-04-27 11:56:33 UTC

When I disable DRI on my M6, I get bad rendering of fonts that looks like all
the caching issues I've seen before.  I tried replacing RB2D_DSTCACHE_* with
RB3D_DSTCACHE_*, since the rv200 doc indicates that RB2D_DSTCACHE* are read-only
mirrors of RB3D_DSTCACHE_*, and that fixed the issue.  The DRM uses RB3D, so
that's probably why we don't see the issue there.

I only had to do it for radeon_accel.c, interestingly enough -- I'll talk about
radeon_exa.c in another bug.  Patch will be attached shortly.

Tested with CVS server+driver as of 2006-04-25 or newer.  I haven't encountered
the issue much before, but I've always got DRI on.

Looks good, go ahead and commit as far as I'm concerned.
