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 / Fedora 21 64-bit edition
• No discrete GPU present in the system

• Go to the top of the repo: cd Linux-HSA-Drivers-And-Images-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-0.6.1/ubuntu/*.deb

• For Fedora, install the kernel package and update initramfs using: sudo yum install kfd-0.6.1/fedora/*.rpm ; sudo dracut --force --add-drivers "amd_iommu_v2 radeon_kfd" "/boot/initramfs-3.14.4-1.kfd.fc21.x86_64.img" 3.14.4-1.kfd.fc21.x86_64

• Reboot the system to install the new kernel and enable the HSA kernel driver: sudo reboot

#####Obtaining kernel source code

Source code used to build the kernel can be downloaded with the following command : git clone -b v0.6.1 git://people.freedesktop.org/~gabbayo/linux.git

For Ubuntu, the kernel images were built using Ubuntu mainline kernel PPA patches, which can be downloaded with the following command : wget http://people.freedesktop.org/~gabbayo/kfd-v0.6.1/0001-base-packaging.patch ; wget http://people.freedesktop.org/~gabbayo/kfd-v0.6.1/0002-debian-changelog.patch ; wget http://people.freedesktop.org/~gabbayo/kfd-v0.6.1/0003-configs-based-on-Ubuntu-END.patch

Use the instructions in the following wiki page to built the Ubuntu kernel images: https://help.ubuntu.com/community/Kernel/Compile

For Fedora, the kernel images were built using Fedora kernel srpm, which can be downloaded with the following command : wget http://people.freedesktop.org/~gabbayo/kfd-v0.6.1/kernel-3.14.4-1.kfd.fc21.src.rpm

Use the instructions in the following wiki page to built the Fedora kernel images: https://fedoraproject.org/wiki/Building_a_custom_kernel

Alternatively, you can compile the kernel directly by running make inside the kernel directory. With this method, you will need to use the kernel config file located at: http://people.freedesktop.org/~gabbayo/kfd-v0.6.1/3.14.4-config-ubuntu-trusty
