451 config PKG_BUILD_PARALLEL
453 prompt "Compile certain packages parallelized"
456 This adds a -jX option to certain packages that are known to
457 behave well for parallel build. By default the package make processes
458 use the main jobserver, in which case this option only takes effect
459 when you add -jX to the make command.
461 If you are unsure, select N.

466 depends on PKG_BUILD_PARALLEL
469 This passes the main make process jobserver fds to package builds,
470 enabling full parallelization across different packages
472 Note that disabling this may overcommit CPU resources depending on the
473 -j level of the main make process, the number of package
474 submake jobs selected below and the number of actual CPUs present.
475 Example: If the main make is passed a -j4 and the submake -j
476 is also set to 4, we may end up with 16 parallel make processes

492 depends on PKG_BUILD_PARALLEL
496 Always set the default package build rules to parallel build.
498 WARNING: This may break build or kill your cat, as it builds
499 packages with multiple jobs that are probably not tested in
500 a parallel build environment.
502 Only say Y, if you don't mind fixing broken packages.
503 Before reporting build bugs, set this to N and re-run the build.

553 bool "Strip unnecessary functions from libraries"
555 Reduces libraries to only those functions that are necessary for using all
556 selected packages (including those selected as <M>)
