d8d2d382 - kbuild: remove PYTHON variable

Mon, 01 Feb 2021 01:00:24 +0000

kbuild: remove PYTHON variablePython retired in 2020, and some distributions do not provide the'python' command any more.As in commit 51839e29cb59 ("scripts: switch explicitly to Python 3"),we need to use more specific 'python3' to invoke scripts even if theyare written in a way compatible with both Python 2 and 3.This commit removes the variable 'PYTHON', and switches the existingusers to 'PYTHON3'.BTW, PEP 394 (https://www.python.org/dev/peps/pep-0394/) is a helpfulmaterial.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/jobserver-exec

51e46c7a - docs, parallelism: Rearrange how jobserver reservations are made

Thu, 21 Nov 2019 20:59:29 +0000

docs, parallelism: Rearrange how jobserver reservations are madeRasmus correctly observed that the existing jobserver reservation onlyworked if no other build targets were specified. The correct approachis to hold the jobserver slots until sphinx has finished. To fix this,the following changes are made:- refactor (and rename) scripts/jobserver-exec to set an environment variable for the maximally reserved jobserver slots and exec a child, to release the slots on exit.- create Documentation/scripts/parallel-wrapper.sh which examines both $PARALLELISM and the detected "-jauto" logic from Documentation/Makefile to decide sphinx's final -j argument.- chain these together in Documentation/MakefileSuggested-by: Rasmus Villemoes Link: https://lore.kernel.org/lkml/eb25959a-9ec4-3530-2031-d9d716b40b20@rasmusvillemoes.dkSigned-off-by: Kees Cook Link: https://lore.kernel.org/r/20191121205929.40371-4-keescook@chromium.orgSigned-off-by: Jonathan Corbet List of files: /linux-6.15/scripts/jobserver-exec
