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.

ROCt Library
This repository includes the user-mode API interfaces used to interact with the ROCk driver.
Starting at 1.7 release, ROCt uses drm render device. This requires the user to belong to video group. Add the user account to video group with "sudo usermod -a -G video username" command if the user if not part of video group yet. NOTE: Users of Ubuntu 20.04 will need to add the user to the new "render" group, as Ubuntu has changed the owner:group of /dev/kfd to render:render as of that release
ROCk Driver
The ROCt library is not a standalone product and requires that you have the correct ROCk driver set installed. We recommend reading the full compatibility and installation details which are available in the ROCk github:
https://github.com/RadeonOpenCompute/ROCK-Radeon-Open-Compute-Kernel-Driver
Building the Thunk
A simple cmake-based system is available for building thunk. To build the thunk from the the ROCT-Thunk-Interface directory, execute:
mkdir -p build
cd build
cmake ..
make
If the hsakmt-roct and hsakmt-roct-dev packages are desired:
mkdir -p build
cd build
cmake ..
make package
If you choose not to build and install packages, manual installation of the binaries and header files can be done via:
make install
NOTE: For older versions of the thunk where hsakmt-dev.txt is present, "make package-dev" and "make install-dev" are required to generate/install the developer packages. Currently, these are created via the "make package" and "make install" commands
