LoopIsa is a shader that performs a variety of intensive calculations in a loop. It is used by tests such as KFDQMTest.QueuePriorityOn* It contained a scalar load, despite not having any buffer to read from. This load causes page faults on GFX11. It is unclear why it did not cause page faults on earlier ASICs. Remove the load. Signed-off-by: David Francis <David.Francis@amd.com> Change-Id: I7426d0db48e933f3bb870467ea88476f7a283040
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.
