run-clang-tools: run multiprocessing.Pool as context manager

2026-05-27T23:47:51+00:00

`multiprocessing.pool.Pool()` should be used as a context manager so Python can free its internal resources and do a proper cleanup.[1] While at it move the code to read the `compiler_commands.json` so the opened file can be closed before the sub-processes are fork()ed.

gen_compile_commands: Ignore libgcc.a

2026-05-04T19:12:55+00:00

Some architectures link libgcc.a from the toolchain into the kernel. gen_compile_commands trie to read the kbuild .cmd files of its constituent object files, which are not available. Flat out ignore libgcc.a, as it is not built as part of the kernel anyways.

Revert "scripts/clang-tools: Handle included .c files in gen_compile_commands"

2025-12-27T19:48:01+00:00

This reverts commit 9362d34acf91a706c543d919ade3e651b9bd2d6f. Dmitry Vyukov reported that commit 9362d34acf91 ("scripts/clang-tools: Handle included .c files in gen_compile_commands") generates false entries in some cases for C files that are included in other C files but not meant for standalone compilation. For properly supporting clangd, including .c files is discouraged.

scripts/clang-tools: Handle included .c files in gen_compile_commands

2025-11-08T11:18:00+00:00

The gen_compile_commands.py script currently only creates entries for the primary source files found in .cmd files, but some kernel source files text-include others (i.e. kernel/sched/build_policy.c). This prevents tools like clangd from working properly on text-included c files, such as kernel/sched/ext.c because the generated compile_commands.json does not have entries for them. Extend process_line() to detect when a source file includes .c files, and generate additional compile_commands.json entries for them. For included c files, use the same compile flags as their parent and add their parents headers. This enables lsp tools like clangd to work properly on files like kernel/sched/ext.c Signed-off-by: Pat Somaru Reviewed-by: Nathan Chancellor Tested-by: Justin Stitt Tested-by: Eduard Zingerman Link: https://patch.msgid.link/20251008004615.2690081-1-patso@likewhatevs.io Signed-off-by: Nicolas Schier

gen_compile_commands.py: remove code for '\#' replacement

2025-03-15T12:16:21+00:00

Since commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd files for future Make"), '#' in the build command is replaced with $(pound) rather than '\#'. Calling .replace(r'\#', '#') is only necessary when this tool is used to parse .*.cmd files generated by Linux 4.16 or earlier, which is unlikely to happen.

gen_compile_commands.py: fix path resolve with symlinks in it

2023-12-23T14:24:03+00:00

When a path contains relative symbolic links, os.path.abspath() might not follow the symlinks and instead return the absolute path with just the relative paths resolved, resulting in an incorrect path. 1. Say "drivers/hdf/" has some symlinks: # ls -l drivers/hdf/ total 364 drwxrwxr-x 2 ... 4096 ... evdev lrwxrwxrwx 1 ... 44 ... framework -> ../../../../../../drivers/hdf_core/framework -rw-rw-r-- 1 ... 359010 ... hdf_macro_test.h lrwxrwxrwx 1 ... 55 ... inner_api -> ../../../../../../drivers/hdf_core/interfaces/inner_api lrwxrwxrwx 1 ... 53 ... khdf -> ../../../../../../drivers/hdf_core/adapter/khdf/linux -rw-r--r-- 1 ... 74 ... Makefile drwxrwxr-x 3 ... 4096 ... wifi 2. One .cmd file records that: # head -1 ./framework/core/manager/src/.devmgr_service.o.cmd cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \ /path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c 3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct: # ./scripts/clang-tools/gen_compile_commands.py INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \ /path/to/src/framework/core/manager/src/devmgr_service.c not found Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly. # cat compile_commands.json ... { "command": ... "directory": ... "file": "/path/to/bla/drivers/hdf_core/framework/core/manager/src/devmgr_service.c" }, ... Also fix it in parse_arguments(). Signed-off-by: Jialu Xu Signed-off-by: Masahiro Yamada
