Radeon R300 Driver Lands NIR-To-TGSI Code, Old NVIDIA Driver Eyes It Too

The open-source Radeon Linux graphics driver work covered yesterday about a big optimization by leveraging NIR and going through that intermediate representation and relying on common NIR optimizations has now been merged into Mesa 22.0. This is a step-up from the existing open-source OpenGL driver support for old Radeon 9500 through Radeon X1000 series (R500) graphics processors. A similar conversion is also planned for the old Nouveau driver handling NVIDIA "NV30" era graphics processors too...
