Freedreno Lands An A2xx NIR Backend, Other Improvements For Mesa 19.0

Freedreno, for the uninformed, is the open-source driver for Qualcomm Adreno hardware. It's been a community-based, reverse-engineering led effort with the MSM DRM kernel driver that is mainlined as well as the Freedreno Gallium3D driver in Mesa for OpenGL support. While it supports the latest Adreno hardware, recently there has been a bit of resurgence in going back to support the original A2xx series hardware.

Mesa EGL Extension Needed For Universal Driver Configuration GUI Is Almost Landed
The MESA_query_driver extension for EGL is of fundamental importance if there is to be a "universal" graphics driver control panel / configuration GUI for Mesa 3D drivers. The extension briefly landed today in Mesa but ended up being reverted due to build problems.
MESA_query_driver provides an EGL extension that exposes the name of the driver as well as that driver's option list.
