The EVL project is about introducing a simple, scalable and dependable dual kernel architecture for Linux. Details are written on this page: https://evlproject.org/
Folders - 'patches.dovetail' and 'patches.evl-only' contains unnumbered patches. 'patches.dovetail' contains patches from the 'origin/dovetail/master' branch. 'patches.evl-only' contains only EVL real-time core patches. The sequence of applying patches in a series is found in the files 'series.dovetail' and 'series.evl-only', respectively. First, apply 'patches.dovetail' then patches 'patches.evl-only'. These two sources are intended primarily for transferring the current version of the 'EVL' kernel to another version of the Linux kernel using the 'quilt' and 'git quiltimport' tools.
Folder - 'patches.evl' contains a complete series of numbered patches from the 'origin/evl/master' branch GIT repository: https://git.evlproject.org/linux-evl.git. The sequence of which is contained in the file series.evl. This folder and file are Packed in a single archive for easy downloading if you don't need everything.
You can completely restore the contents of this branch by applying the entire series of patches use the 'git am' or 'git quiltimport' command to access the newly created git repository from the archive by downloading the corresponding version from: https://mirrors.edge.kernel.org/pub/linux/kernel/
