[Bug 1742941] Comment bridged from LTC Bugzilla
--- Comment From danie...@au1.ibm.com 2020-02-06 22:14 EDT--- Where we are up to is there is a small amount of progress in the zlib-devel (https://zlib.net/mailman/listinfo/zlib-devel_madler.net) however nothing explicit on or off list about merging arch specific patches (from any architecture vendor). At the request of the community and other vendors, we have added explicit crc32 tests to the zlib and these have been pushed to that upstream PR. https://github.com/madler/zlib/pull/335 Since the patch on this bug report, the code has been changed from ASM to C (to increase the portability ), conformed closer to an upstream style as far a location and interfaces, and improved the test suite as mentioned. The zlib1g-dev package in focal (https://packages.ubuntu.com/focal /zlib1g-dev) still uses configure && make which the upstream PR patches correctly (notably I haven't patched CMakefiles as of today). Building `make crc32_test && ./crc32_test` as a test can be done quickly in the package build process to validate the accuracy. We hope this prudence and validation in the upstream PR https://github.com/madler/zlib/pull/335 can be accepted for the ubuntu-20.04 LTS release of the zlib package while we continue to work with upstream on maintenance.

--- Comment From danie...@au1.ibm.com 2019-04-08 18:59 EDT--- Significant background talks are taking place with Mark Adler about the maintenance of zlib for arch specific performance. Lets see what happens in the next 3 months. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742941 Title: [18.10] zlib: improve crc32 performance on P8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1742941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The patch has been waiting for the zlib maintainer since Feb. 6th. Likewise for all the pull requests submitted since January: https://github.com/madler/zlib/pulls?q=is%3Aopen+is%3Apr Canonical, would it be possible to carry this patchset out-of-tree? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742941 Title: [18.10] zlib: improve crc32 performance on P8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1742941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
