Linux 5.9: Checkpoint/Restore and Scheduler Improvements

Filed under
Linux
  • Checkpoint/Restore Of Unprivileged Processes Sent In For Linux 5.9

    Linux 5.9 is bringing another feature that's long been baking and of interest to a growing number of stakeholders... checkpoint/restore functionality of unprivileged processes.

    With Linux 5.9 all the pieces should be in place for allowing checkpoint/restore of processes not running as root. This saving and restoring of processes can be used for functionality like container migration, moving workloads in HPC environments, or for the Java JVM to speed-up startup time. The Linux kernel has supported checkpoint/restore of processes but only as root until now.

  • Linux 5.9 Continues Working On A Variety Of Scheduler Improvements

    Among the many pull requests sent in for the Linux 5.9 merge window by longtime developer Ingo Molnar are the usual assortment of scheduler improvements.

    [...]

    - The deadline scheduler is now capacity-aware and has seen other improvements too.

    - UClamp performance improvements for this utilization clamping functionality.

    - Cleanups to the energy/power-aware scheduling.

Plasma and the systemd startup

Landing in master, plasma has an optional new startup method to launch and manage all our KDE/Plasma services via a system --user interface rather than the current boot scripts. This will be available in Plasma 5.21. It is currently opt-in, off by default. I hope to make it the default where available after more testing and feedback, but it is important to stress that the current boot-up method will exist and be supported into the future. A lot of work was put into splitting and tidying so the actual amount of duplication in the end result is quite small and manageable. Read more

Mozilla Thunderbird 78.3 Is Out and You Can Finally Upgrade from Earlier Versions

Mozilla Thunderbird 78.3 open-source and free email client has arrived with more improvements and bug fixes, and you can now finally upgrade from older Thunderbird releases. When Thunderbird 78 launched earlier this year, it didn’t support automatic upgrades from version 68 or earlier. Automatic upgrade was blocked intentionally due to the revamped extension system that only supports MailExtensions, not classic extensions, to no break your Thunderbird installations. Three months later, Mozilla enabled automatic upgrades in Thunderbird with version 78.2.2 released a couple of weeks ago. Now Thunderbird 78.3 is out and it disables the installation of “legacy” MailExtensions. Read more
