| 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 |
