Subject: Re: [PATCH] kbuild: Show Kconfig fragments in "help"
Le 25/08/2023 à 00:36, Kees Cook a écrit :
> Doing a "make help" would show only hard-coded Kconfig targets and
> depended on the archhelp target to include ".config" targets. There was
> nothing showing global kernel/configs/ targets. Solve this by walking

> Update all Kconfig fragments to include help text and adjust archhelp
> targets to avoid redundancy.

> Adds the following section to "help" target output:

> Configuration fragment targets (for enabling various Kconfig items):
> debug.config - Debugging for CI systems and finding regressions
> kvm_guest.config - Bootable as a KVM guest
> nopm.config - Disable Power Management
> rust.config - Enable Rust
> tiny-base.config - Minimal options for tiny systems
> tiny.config - Smallest possible kernel image
> x86_debug.config - Debugging options for tip tree testing
> xen.config - Bootable as a Xen guest
> tiny.config - x86-specific options for a small kernel image
> xen.config - x86-specific options for a Xen virtualization guest
