Changes in version 2: use openmp for multi-processing instead of NSPR library, as requested by upstream. Add a link to the upstream submission to patches.
These two patches add multi-threaded features to RPM to speed up the do_package_write_rpm task. Specifically: 1) Multi-threaded xz compressor is used instead of default single-threaded gz. This has the most dramatic effect when a recipe produces a smaller number of large-sized packages. 2) Packages creation is run in multiple threads via thread pools. This is most beneficial when a recipe produces a large amount of small packages. Some not very scientific benchmarks for time and .rpm sizes (time is measured for do_package_write_rpm tasks only): webkitgtk before: 9m12s 1550M after: 1m40s 858M glibc-locale before: 2m52s 125M after: 30s 56M glibc before: 46s 54M after: 13s 38M perl before: 1m09s 63M after: 45s 42M python3 before: 30s 38M after: 18s 24M The following changes since commit 576821ea0a7558b626ccc87e9ae0e9ee40864956: bitbake: bitbake-layers: check layer dependencies before adding (2017-06-06 19:52:51 +0100) are available in the git repository at: git://git.yoctoproject.org/poky-contrib akanavin/parallel-rpm http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=akanavin/parallel-rpm Alexander Kanavin (2): package_rpm.bbclass: use multithreaded xz compression rpm: run binary package generation via thread pools meta/classes/package_rpm.bbclass | 2 + ...y-package-building-into-a-separate-functi.patch | 83 ++++++++ ...-binary-package-creation-via-thread-pools.patch | 125 ++++++++++++ ...c-make-operations-over-string-pools-threa.patch | 207 ++++++++++++++++++++ ...c-remove-static-local-variables-from-buil.patch | 216 +++++++++++++++++++++ meta/recipes-devtools/rpm/rpm_git.bb | 4 + 6 files changed, 637 insertions(+) create mode 100644 meta/recipes-devtools/rpm/files/0001-Split-binary-package-building-into-a-separate-functi.patch create mode 100644 meta/recipes-devtools/rpm/files/0002-Run-binary-package-creation-via-thread-pools.patch create mode 100644 meta/recipes-devtools/rpm/files/0003-rpmstrpool.c-make-operations-over-string-pools-threa.patch create mode 100644 meta/recipes-devtools/rpm/files/0004-build-pack.c-remove-static-local-variables-from-buil.patch -- 2.11.0 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
