-Changes needed to DPDK are stored here as git patch files. Maintaining these
-files using “git format-patch” and “git am” will make it simpler to manage
-these changes. Patches made to DPDK should only be temporary until they are
-accepted upstream and made available in the next DPDK release.
-
-The following is the method used to generate these patches:
-
-1. Git clone the DPDK to a new directory:
- # git clone http://dpdk.org/git/dpdk dpdk
-
-2. Create a branch based on the DPDK release you wish to patch.
-Note, “git tag” will show you all the release tags. The following example is
-for DPDK release tag “v2.2.0” and will create a branch named “two_dot_two”.
- # cd dpdk
- # git checkout -b two_dot_two v2.2.0
-
-3. Apply all the existing VPP DPDK patches to this new branch.
- # git am <VPP directory>/dpdk/dpdk-2.2.0_patches/*
-
-4. Make your changes and commit your change to your DPDK repository.
- # <edit files>
- # git commit -s
-
-5. Create the patch files with format-patch. This creates all the patch files
-for your branch (two_dot_two), with your latest commits as the last ones.
- # git format-patch master..two_dot_two
-
-6. Copy, add and commit the new patches into the VPP patches directory.
- # cp <new patch files> <VPP directory>/dpdk/dpdk-2.2.0_patches
- # cd <VPP directory>
- # git add dpdk/dpdk-2.2.0_patches/<new patch files>
- # git commit -s
