I would like it if Intel could avoid garbage-collecting older-HW shared code for at least a release due aforementioned WIPs, but I think it's time to call the classic i965_dri.so and i915_dri.so done. +1 from me assuming that we validate that one can actually get a working X server with the mesa-legacy set installed. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
