### AI overview

NOCL is a developing Mesa Gallium driver that uses NVIDIA's proprietary CUDA driver and PTX representation to provide an open-source OpenCL option on Linux. Its merge request is pending; it supports more OpenCL extensions than NVIDIA's proprietary OpenCL driver and may aid performance comparisons and PTX development. PTX-to-NIR support could also matter for DLSS with the NVK Mesa driver.

### Source excerpt

In development the past year has been the Mesa Gallium3D API implemented atop NVIDIA's CUDA driver API. Initially named "CLUDA" and now going by "NOCL", this Mesa code paired with Rusticl is working well for OpenCL atop the NVIDIA proprietary driver as a new compute option...
