- 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. The diff should include all the non-upstream patches. How to verify it Build the Kernel and verified if all the patches are applied properly Signed-off-by: Vivek Reddy Karri <vkarri@nvidia.com>
