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.

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.
