- lnx64a/libhsakmt.so.1
-
A bash script which checks if kfd is installed correctly
The kernel image is built from a source tree based on the 3.17.2 upstream release plus :
- The HSA kernel driver ("amdkfd"), which works with the radeon graphics driver.
- Fixes and improvements to the radeon and amd_iommu(v2) drivers, mm and mmu_notifier code.
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.
This release is intended for use with any hardware configuration that contains a Kaveri APU.
The motherboards must support the FM2+ socket, 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 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-1.0/ubuntu/*.deb -
For Fedora, install the kernel package and update initramfs using:
sudo yum install kfd-1.0/fedora/*.rpm ; sudo dracut --force --add-drivers "amd_iommu_v2 amdkfd" "/boot/initramfs-3.17.2-300.amdkfd.fc21.x86_64.img" 3.17.2-300.amdkfd.fc21.x86_64 -
Reboot the system to install the new kernel and enable the HSA kernel driver:
sudo reboot
