Because dma32 zone is on node 0, use all system memory on node 0 will cause TTM eviction to free dma32 zone for other devices which only work with 32bit physical address. The TTM eviction and restore may take too long and cause queue timeout. Running on other NUMA nodes, the NUMA default memory policy is MPOL_PREFERRED, means TTM will get pages from local node first, and then get remaining pages from other nodes. Check /proc/buddyinfo can confirm this. Reset NUMA bind to all after the test. Change-Id: I39b373c07a2d5aa396f5c7602bffabab0481930f Signed-off-by: Philip Yang <Philip.Yang@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
