The purpose of this KFDTest is to investigate the behaviour of an SDMA queue when an invalid memory address is used. v2: Don't wait for SDMA queue to finish - it won't finish because of the gpuvm fault. v3: Create kfd event before SDMA queue submission. This fix the issue that gpuvm fault happens earlier than kfd event is created then KFD exception handler can't find the kfd event (to wake up kfd test) v4: Instead of using 0x12345678 as the invalid VA, map one page of FB to gpu and unmap it. Use the mapped GPUVA as the invalid address Change-Id: I58af1511f75d869adddede302b238c2725f3fe5a Signed-off-by: Ori Messinger <Ori.Messinger@amd.com> Signed-off-by: Oak Zeng <Oak.Zeng@amd.com>
ROCt Library
This repository includes the user-mode API interfaces used to interact with the ROCk driver. Currently supported agents include only the AMD/ATI Fiji family of discrete GPUs.
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.
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
make package-dev
