.gitignore: ignore *.rpm

2022-12-30T08:22:14+00:00

Previously, *.rpm files were created under $HOME/rpmbuild/, but since commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji"), srcrpm-pkg creates the source rpm in the kernel tree because it sets '_srcrpmdir'. Signed-off-by: Masahiro Yamada

kbuild: Cleanup DT Overlay intermediate files as appropriate

2022-11-18T20:45:30+00:00

%.dtbo.o and %.dtbo.S files are used to build-in DT Overlay. They should should not be removed by Make or the kernel will be needlessly rebuilt. These should be removed by "clean" and ignored by git like other intermediate files.

Kbuild: add Rust support

2022-09-28T07:02:20+00:00

Having most of the new files in place, we now enable Rust support in the build system, including `Kconfig` entries related to Rust, the Rust configuration printer and a few other bits.

rust: add `.rustfmt.toml`

2022-09-28T07:02:20+00:00

This is the configuration file for the `rustfmt` tool. `rustfmt` is a tool for formatting Rust code according to style guidelines. It is very commonly used across Rust projects. The default configuration options are used.

scripts: add `generate_rust_analyzer.py`

2022-09-28T07:02:06+00:00

The `generate_rust_analyzer.py` script generates the configuration file (`rust-project.json`) for rust-analyzer. rust-analyzer is a modular compiler frontend for the Rust language. It provides an LSP server which can be used in editors such as VS Code, Emacs or Vim.

kbuild: split the second line of .mod into .usyms

2022-05-07T18:16:59+00:00

The *.mod files have two lines; the first line lists the member objects of the module, and the second line, if CONFIG_TRIM_UNUSED_KSYMS=y, lists the undefined symbols. Currently, we generate *.mod after constructing composite modules, otherwise, we cannot compute the second line. No prerequisite is required to print the first line. They are orthogonal. Splitting them into separate commands will ease further cleanups. This commit splits the list of undefined symbols out to *.usyms files. Previously, the list of undefined symbols ended up with a very long line, but now it has one symbol per line. Use sed like we did before commit 7d32358be8ac ("kbuild: avoid split lines in .mod files"). Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

.gitignore: ignore only top-level modules.builtin

2021-05-01T15:43:35+00:00

modules.builtin used to be created in every directory. Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), modules.builtin is created only in the top directory. Add the '/' prefix so that it matches to only the modules.builtin located in the top directory. It has been more than one year since that change. I hope this will not flood 'Untracked files' of 'git status'. Signed-off-by: Masahiro Yamada

.gitignore: move tags and TAGS close to other tag files

2021-05-01T15:43:35+00:00

For consistency, move tags and TAGS close to the cscope and GNU Global patterns. I removed the '/' prefix in case somebody wants to manually create tag files in sub-directories. Signed-off-by: Masahiro Yamada

kbuild: generate Module.symvers only when vmlinux exists

2021-04-24T20:17:02+00:00

The external module build shows the following warning if Module.symvers is missing in the kernel tree. WARNING: Symbol version dump "Module.symvers" is missing. Modules may not have dependencies or modversions. I think this is an important heads-up because the resulting modules may not work as expected. This happens when you did not build the entire kernel tree, for example, you might have prepared the minimal setups for external modules by 'make defconfig && make modules_preapre'. A problem is that 'make modules' creates Module.symvers even without vmlinux. In this case, that warning is suppressed since Module.symvers already exists in spite of its incomplete content. The incomplete (i.e. invalid) Module.symvers should not be created. This commit changes the second pass of modpost to dump symbols into modules-only.symvers. The final Module.symvers is created by concatenating vmlinux.symvers and modules-only.symvers if both exist. Module.symvers is supposed to collect symbols from both vmlinux and modules. It might be a bit confusing, and I am not quite sure if it is an official interface, but presumably it is difficult to rename it because some tools (e.g. kmod) parse it.

kbuild: add CONFIG_VMLINUX_MAP expert option

2021-04-24T20:12:26+00:00

It can be quite useful to have ld emit a link map file, in order to debug or verify that special sections end up where they are supposed to, and to see what LD_DEAD_CODE_DATA_ELIMINATION manages to get rid of. The only reason I'm not just adding this unconditionally is that the .map file can be rather large (several MB), and that's a waste of space when one isn't interested in these things. Also make it depend on CONFIG_EXPERT. Signed-off-by: Rasmus Villemoes Signed-off-by: Masahiro Yamada
