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 + |
