on NUMA system, node 0 may have no memory, application pass node id 0 to hsaKmtAllocMemory will fail because mbind to specify the allocation from node 0 return EINVAL. Add new flag NoNUMABind for application to pass it to hsaKmtAllocMemory to skip mbind. hsaKmtCreateEvent and hsaKmtCreateQueue specify the new flag NoNUMABind to allocate system memory for event page and CWSR area, don't bind the system memory to a specific NUMA node.

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
