As far as I have seen this is like 99% code from the TTM pool.
Yea, it evolved into being mostly logic from the TTM pool (or code that was very similar to begin with), but it's not where it started. My old days at IBM makes me wary of claiming it's no longer the Ship of Theseus. So instead I think I'll have to just throw out my patch and rewrite it in full (so apologies in advance for any review issues I introduce/reintroduce). thanks -john _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
