New target, kernel patch hierarchy?

For Developers
1

Hi;

I am defining a new target using kernel 5.4 based on target/linux/bcm27xx/bcm2710 from which I want to use patches from target/linux/bcm27xx (bcm2710 subtarget has no patches) in addition to my own kernel patches.

When I compile the kernel, patches from target/linux/generic/hack-5.4 are used, in addition to my patches defined in target/linux/MyCustomTarget/patches-5.4

Q1: should the patch order be generic,bcm27xx,MyCustomTarget OR bcm27xx,MyCustomTarget (no generic)
Q2: How best to apply generic (if required), target/linux/bcm27xx/patches, then my patches?

Please advise...
Regards;
Bill

TARGET patches are for the specific target, the generic patches are tree-wide.

I believe the generic backport and hack patches are applied first, then the TARGET patches are applied. You can find the naming convention for the patches below.

Thanks;

My biggest problem was defining as a target (therefore, bcm27xx patches not applied), not subtarget of bcm27xx. Bit of code inspection was required. Let U know if further problems.

Big thanks for explaining patch order and generic are treewide...
