This patch restructures the CWSR basic test and allows for creating parameterized CWSR tests. This patch introduces four parameterizations. These tests behave as follows: This test dispatches the IterateIsa shader, which continuously increments a vgpr for (num_witems / WAVE_SIZE) waves. While this shader is running, dequeue/requeue requests are sent in a loop to trigger CWSRs. This test defines a CWSR threshold. Once the number of CWSRs triggered reaches the threshold, a known-value is filled into the inputBuf to signal the shader to exit. 4 parameterized tests are defined: KFDCWSRTest.BasicTest/0 KFDCWSRTest.BasicTest/1 KFDCWSRTest.BasicTest/2 KFDCWSRTest.BasicTest/3 0: 1 work-item, CWSR threshold of 10 1: 256 work-items, CWSR threshold of 50 2: 512 work-items, CWSR threshold of 100 3: 1024 work-items, CWSR threshold of 1000 Tuple Format: (num_witems, cwsr_thresh) num_witems: Defines the number of work-items. cwsr_thresh: Defines the number of CWSRs to trigger.

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.
