1### v3d backend 2 3This implements some of v3d using the closed source v3dv3 tree's 4C/C++-based simulator. All execution is synchronous. 5 6Export: `MESA_LOADER_DRIVER_OVERRIDE=v3d 7LD_PRELOAD=$prefix/lib/libv3d_drm_shim.so`. The v3dv3 version exposed 8will depend on the v3dv3 build -- 3.3, 4.1, and 4.2 are supported. 9 10### v3d_noop backend 11 12This implements the minimum of v3d in order to make shader-db work. 13The submit ioctl is stubbed out to not execute anything. 14 15Export `MESA_LOADER_DRIVER_OVERRIDE=v3d 16LD_PRELOAD=$prefix/lib/libv3d_noop_drm_shim.so`. This will be a V3D 174.2 device. 18
