This is to measure the laterncy + overhead of sdma packet consumption on p2p. It is Similar with QueueLatency test. What's more, the queue's overhead with different workload show more details. test result on two gfx900.

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.
