Linux kernel ============ AMD version ----------- This is a branch used by AMD projects using RyzenAI XDNA accelerator like https://github.com/Xilinx/mlir-aie This is a stable Linux version with some patches for IOMMU SVA support and a bug fix for AMD PMC about sleep state. The kernels are provided as branches pointing to some versions, like v6.8.7-iommu-sva-part4-v7. If you are just interested by always having the latest kernel, the v6.8-iommu-sva-part4-v7 branch points to the latest 6.8.x branch from this repository. For the bug fix for AMD PMC about sleep state, there are also the branches per kernel version, such as v6.8.7-iommu-sva-part4-v7+pmc-10ms-delay If you are just interested by always having the latest kernel with this bug fix, the v6.8-iommu-sva-part4-v7+pmc-10ms-delay branch points to the latest 6.8.x branch with the fix from this repository. To compile this kernel in a nutshell: git clone --depth=1 --branch v6.8-iommu-sva-part4-v7 git@github.com:AMD-SW/linux cd linux # Often people compile a kernel from source code by reusing # their current config with something like: cp /boot/config-`uname -r` <your_build_dir>/.config # But if you do not have a `.config` file modern enough to start with, # you can get one for Debian/Ubuntu with: wget https://gist.github.com/keryell/55c57d5f0280de8943fb8cca64059764/raw/27fdbb7c86060ec58d8470fe391d2cd633f6e89f/.config # To compile and make some Debian/Ubuntu packages: make -j `nproc` bindeb-pkg # Install the kernel. The exact names will depend on your configuration sudo apt reinstall ../linux-headers-6.8.7+iommu-sva-part4-v7+_6.8.7-00095-gef3f1f49a69d-1_amd64.deb ../linux-image-6.8.7+iommu-sva-part4-v7+_6.8.7-00095-gef3f1f49a69d-1_amd64.deb ../linux-libc-dev_6.8.7-00095-gef3f1f49a69d-1_amd64.deb ``` Generic README -------------- There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
