-
Fedora images:
- Fedora release is currently unavailable for KFD 1.6
-
Userspace wrapper library called libhsakmt:
- libhsakmt_1.6.0_amd64.deb
-
A bash script which checks if kfd is installed correctly
The kernel image is built from a source tree based on the 4.0.0 upstream release plus :
- Features in the HSA kernel driver ("amdkfd") that are not yet upstreamed to the mainline Linux kernel.
- The new AMD kernel graphic driver ("amdgpu") that is not yet upstreamed to the mainline Linux kernel.
- Minor changes to "amd_iommu_v2" kernel driver, which are only present in later linux kernel versions
Please note that the libhsakmt library in this repository is NOT compatible with amdkfd that is distributed as part of the mainline Linux kernel from 3.19 and onward.
If you prefer to work with the upstreamed amdkfd in the mainline Linux kernel, you can get the corresponding libhsakmt from:
http://cgit.freedesktop.org/~gabbayo/libhsakmt/
This release is intended for use with any hardware configuration that contains a Kaveri or Carrizo APU.
The motherboards must support run latest BIOS version and have the IOMMU enabled in the BIOS.
The following is a reference hardware configuration that was used for testing purposes:
- APU: AMD A10-7850K APU
- Motherboard: ASUS A88X-PRO motherboard (ATX form factor)
- Memory: G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133
- OS: Ubuntu 14.04 64-bit edition
- No discrete GPU present in the system
-
Downloading the kernel binaries from the repo
git clone -b kfd-v1.6.x https://github.com/HSAFoundation/HSA-Drivers-Linux-AMD.git -
Go to the top of the repo:
cd HSA-Drivers-Linux-AMD -
Configure udev to allow any user to access /dev/kfd. As root, use a text editor to create /etc/udev/rules.d/kfd.rules containing one line: KERNEL=="kfd", MODE="0666", Or you could use the following command:
echo "KERNEL==\"kfd\", MODE=\"0666\"" | sudo tee /etc/udev/rules.d/kfd.rules -
For Ubuntu, install the linux-image kernel package using:
sudo dpkg -i kfd-1.6/ubuntu/*.deb -
Reboot the system to install the new kernel and enable the HSA kernel driver:
sudo reboot -
Check the HSA driver installation:
cd HSA-Drivers-Linux-AMD; ./kfd_check_installation.sh
