Vram size is relatively smaller in APU, e.g. 512MB.
Current MMBench doesn't support small vram system.
Running MMBench may have below errors:
[ RUN ] KFDMemoryTest.MMBench
[ ] Found VRAM of 512MB.
[ ] Test (avg. ns) alloc mapOne umapOne mapAll umapAll free

1. Note on building kfdtest To build this kfdtest application, the following libraries should be already installed on the building machine: libdrm libdrm_amdgpu libhsakmt If libhsakmt is not installed, but the headers and libraries are present locally, you can specify its directory by export LIBHSAKMT_PATH=/*your local libhsakmt folder*/ With that, the headers and libraries are searched under LIBHSAKMT_PATH/include and LIBHSAKMT_PATH/lib respectively. 2. How to run kfdtest Just run "./run_kfdtest.sh" under the building output folder. You may need to specify library path through: export LD_LIBRARY_PATH=/*your library path containing libhsakmt*/ Note: you can use "run_kfdtest.sh -h" to see more options.
