KFDPerformanceTest.P2PBandWidthTest[push, push] takes about 3 seconds on 4 gfx906, the default g_TestTimeout 2 seconds is not enough to wait for sDMA queue rptr is consumed. Use kfdtest command line option --timeout=6000, the test is finished and result is reasonable twice as P2PBandWidthTest[push, none]. Change P2PBandWidthTest wait timeout to 6 seconds. Add timeout argument to function WaitOnValue, BaseQueue.Wait4PacketConsumption SDMAQueue.Wait4PacketConsumption, PM4Queue.Wait4PacketConsumption with default value is g_TestTimeOut.
