1, Initialize the registers before using them is the best practice. Though the use case here doesn't care whether the registers are initialized or not, some emulators complain the "read_before_write" behavior. Initialize the registers used to silence these complaints. 2, Update s_wait stuff for gfx12. Change-Id: I462b2b0b5017dd2876a5954169d3b6b2f1c2a75b Signed-off-by: Lang Yu <lang.yu@amd.com>
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=/path/to/libhsakmt.a With that, CMake/make will look for the lib at LIBHSAKMT_PATH/libhsakmt.a Note that this assumes that you will be building kfdtest from the same thunk found in ../.. 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=/path/to/libhsakmt.a Note: you can use "run_kfdtest.sh -h" to see more options.
