The kfdtest multi-gpu extension only allows using the first gpu(in topology order) as default gpu for KFDEvictTest test case. We should allow user to select any gpu in system as default gpu to run KFDEvictTest test case. Signed-off-by: Xiaogang Chen<Xiaogang.Chen@amd.com> Change-Id: I8848771d92ae2812fbb96e917454ab3b4a71a2fa
