llvmpipe is OpenGL 4.5 conformant.
(I just sent the below email to mesa3d developer list). Just to let everyone know, a month ago I submitted the 20.2 llvmpipe driver for OpenGL 4.5 conformance under the SPI/X.org umbrella, and it is now official[1]. Thanks to everyone who helped me drive this forward, and to all the contributors both to llvmpipe and the general Mesa stack that enabled this. Big shout out to Roland Scheidegger for helping review the mountain of patches I produced in this effort. My next plans involved submitting lavapipe for Vulkan 1.0, it's at 99% or so CTS, but there are line drawing, sampler accuracy and some snorm blending failure I have to work out. I also ran the OpenCL 3.0 conformance suite against clover/llvmpipe yesterday and have some vague hopes of driving that to some sort of completion. (for GL 4.6 only texture anisotropy is really missing, I've got patches for SPIR-V support, in case someone was feeling adventurous). Dave. [1] https://www.khronos.org/confor m
