## Mellanox non-upstream linux kernel patches ##
Made non-upstream patch design order aware (#14434) - Why I did it Currently, non upstream patches are applied only after upstream patches. Depends on sonic-net/sonic-linux-kernel#313. Can be merged in any order, preferably together - What I did it Non upstream Patches that reside in the sonic repo will not be saved in a tar file bur rather in a folder pointed out by EXTERNAL_KERNEL_PATCH_LOC. This is to make changes to the non upstream patches easily traceable. The build variable name is also updated to INCLUDE_EXTERNAL_PATCHES Files/folders expected under EXTERNAL_KERNEL_PATCH_LOC EXTERNAL_KERNEL_PATCH_LOC/ ├──── patches/ ├── 0001-xxxxx.patch ├── 0001-yyyyyyyy.patch ├── ............. ├──── series.patch series.patch should contain a diff that is applied on the sonic-linux-kernel/patch/series file.

To include non-upstream patches into the sonic-linux image during build time, the `INCLUDE_EXTERNAL_PATCHES=y` flag has to be provided. By default, the directory pointed by EXTERNAL_KERNEL_PATCH_LOC will be used and it must follow the following structure. To use a publicly accessible tar of the non-upstream patches, also provide the `EXTERNAL_KERNEL_PATCH_URL` variable

1. It should contain a file named series.patch. This should contain a diff that is applied on the sonic-linux-kernel/patch/series file. The diff should include all the non-upstream patches.
2. All the patches should be present in the patches folder
3. Developers should make sure patches apply cleanly over the existing patches present in the src/sonic-linux-kernel .
### Include the non upstream patches while building sonic linux kernel
Set `INCLUDE_EXTERNAL_PATCHES=y` using `SONIC_OVERRIDE_BUILD_VARS` to include these changes before building the kernel.
- Eg: `NOJESSIE=1 NOSTRETCH=1 NOBUSTER=1 make SONIC_OVERRIDE_BUILD_VARS=' INCLUDE_EXTERNAL_PATCHES=y ' target/debs/bullseye/linux-headers-5.10.0-12-2-common_5.10.103-1_all.deb`
