On some asics, like tonga, the memory alignment size is as big as 0x8000. fmm_allocate* alloc vm area with size passed in which is not aligned mostly. But __fmm_release free vm area with vm_object_t->size which is aligned. That might cause aperture_release_area fail to free the vm area as the size might be bigger than zone itself or it just free another vm area nearby unexpected. This patch somehow will alloc more space than it needed on tonga. gfx900+ is not affected. Change-Id: I5a88c92b08c4e6f6bc05881798f769b55d6debe9 Signed-off-by: xinhui pan <xinhui.pan@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

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:
