1### radeon_noop backend
2
3This implements the minimum of the radeon kernel driver in order to make shader-db work.
4The submit ioctl is stubbed out to not execute anything.
5
6Export `MESA_LOADER_DRIVER_OVERRIDE=r300
7LD_PRELOAD=$prefix/lib/libradeon_noop_drm_shim.so`. (or r600 for r600-class HW)
8
9By default, rv515 is exposed.  The chip can be selected an environment
10variable like `RADEON_GPU_ID=CAYMAN` or `RADEON_GPU_ID=0x6740`.
11
12### amdgpu_noop backend
13
14This implements the minimum of the amdgpu kernel driver.  The submit ioctl is
15stubbed out to not execute anything.
16
17Export `LD_PRELOAD=$prefix/lib/libamdgpu_noop_drm_shim.so`.
18
19To specify the device to expose, set the environment variable `AMDGPU_GPU_ID`
20to
21
22 - `renoir` to expose a `CHIP_RENOIR` device
23 - `raven` to expose a `CHIP_RAVEN` device
24 - `stoney` to expose a `CHIP_STONEY` device
25
26Further names follow the `CHIP_*` enum values. By default, the `CHIP_RENOIR`
27device is exposed.
28
29To add a new device, `amdgpu_devices.c` needs to be modified.
30`amdgpu_dump_states` can be used to dump the relevant states from a real
31device.
