>When was the last time a GPU driver was added by reverse engineering it Freedreno (for the Adreno family) Etnaviv (for the Vivante family) Panfrost / Bifrost (for Mali) All these RE efforts built on each other, although the GPUs are different the tools built to do the RE were shared (and I think ashai is benefiting too). AFAIK Google has now hired Rob Clark the Freedreno maintainer who started all this to work on Freedreno for Android / ChromeOS Upstream Linux now has pretty good GPU support for all the major mobile GPUs these days. The hold out has been PowerVR but they are now working on an official (not reverse engineered) driver.
