SB is enabled by default, but you can use R600_DEBUG=nir,nosb to run NIR with disabled SB. Play your favorite games with the back-end enabled and report bugs at https://gitlab.freedesktop.org/mesa/mesa/-/issues. If you are a developer and have the hardware, just pick a task from the list above and start fixing.

The NIR Intermediate Representation (NIR) is the optimizing compiler stack that sits at the core of most Mesa drivers’ shader compilers.

When the r600 driver are originally implemented, TGSI was the dominating intermediate representation (IR) used by the shader compilers in Mesa. Several years back, NIR (new intermediate representation) was introduced, which has since been adopted by most drivers in Mesa. Among other things, NIR allows adding hardware specific opcodes that make it easy to transform the shader code to something that can easily be translated into hardware specific assembly.
