Ugh. Based on my experience with wfb, I wouldn't expect that to perform better than the current fallback paths in glamor. BTW, as I reported in https://bugs.freedesktop.org/show_bug.cgi?id=68524#c27 , accessing the texture memory in VRAM directly isn't much faster than those either with a discrete GPU. So, while I highly applaud the goal of making a glamor based generic driver generally usable (especially for XWayland), please don't bake in such platform specific assumptions then. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer
