Include HTML output generated with rustdoc into the Linux kernel documentation on Rust. Change target `make htmldocs` to combine RST Sphinx and the generation of Rust documentation, when support is available. Signed-off-by: Carlos Bilbao <carlos.bilbao@xxxxxxx> --- Changes since V1: - Work on top of v6.1-rc1. - Don't use rustdoc.rst, instead add link to Documentation/rust/index.rst. - In Documentation/Makefile, replace @make rustdoc for $(Q)$(MAKE) rustdoc. - Don't do LLVM=1 for all rustdoc generation within `make htmldocs`. - Add spaces on definition of RUSTDOC_OUTPUT, for consistency. --- Documentation/Makefile | 4 ++++ Documentation/rust/index.rst | 3 +++ rust/Makefile | 15 +++++++++------ 3 files changed, 16 insertions(+), 6 deletions(-) diff --git a/Documentation/Makefile b/Documentation/Makefile index 64d44c1ecad3..f537cf558af6 100644 --- a/Documentation/Makefile +++ b/Documentation/Makefile @@ -92,6 +92,10 @@ quiet_cmd_sphinx = SPHINX $@ --> file://$(abspath $(BUILDDIR)/$3/$4) fi htmldocs: +# If Rust support is available, add rustdoc generated contents +ifdef CONFIG_RUST + $(Q)$(MAKE) rustdoc +endif @$(srctree)/scripts/sphinx-pre-install --version-check @+$(foreach var,$(SPHINXDIRS),$(call loop_cmd,sphinx,html,$(var),,$(var))) diff --git a/Documentation/rust/index.rst b/Documentation/rust/index.rst index 4ae8c66b94fa..4005326c3ba9 100644 --- a/Documentation/rust/index.rst +++ b/Documentation/rust/index.rst @@ -6,6 +6,9 @@ Rust Documentation related to Rust within the kernel.
