What this code was for: Before gtt mapping, we were doing software fallbacks in Mesa with pread/write on pages at a time (or worse) of the framebuffer. It would regularly result in hitting the same page again, since I was only caching the last page I'd pulled out, instead of keeping a whole copy of the framebuffer during the fallback. Since we've been doing gtt mapping for years at this point, I'm happy to see the code die. I'm not sure about the rest of the code. In particular, for the code that's switching between gtt and cpu mappings to handle a read/write, I'm concerned about whether the behavior matches for tiled objects. I haven't reviewed enough to be sure. -------------- next part -------------- A non-text attachment was scrubbed...
