Rhys Perry f1db717ff6 amd/drm-shim: enable conformant_trunc_coord for navi31 
No idea if this is more typical of navi31 or not, but it's what my system
has.

radeon_noop backend

This implements the minimum of the radeon kernel driver in order to make shader-db work. The submit ioctl is stubbed out to not execute anything.

Export MESA_LOADER_DRIVER_OVERRIDE=r300 LD_PRELOAD=$prefix/lib/libradeon_noop_drm_shim.so. (or r600 for r600-class HW)

By default, rv515 is exposed. The chip can be selected an environment variable like RADEON_GPU_ID=CAYMAN or RADEON_GPU_ID=0x6740.

amdgpu_noop backend

This implements the minimum of the amdgpu kernel driver. The submit ioctl is stubbed out to not execute anything.

Export LD_PRELOAD=$prefix/lib/libamdgpu_noop_drm_shim.so.

To specify the device to expose, set the environment variable AMDGPU_GPU_ID to

  • renoir to expose a CHIP_RENOIR device
  • raven to expose a CHIP_RAVEN device
  • stoney to expose a CHIP_STONEY device

Further names follow the CHIP_* enum values. By default, the CHIP_RENOIR device is exposed.

To add a new device, amdgpu_devices.c needs to be modified. amdgpu_dump_states can be used to dump the relevant states from a real device.
