[Bug 1919154] Re: Enable CONFIG_NO_HZ_FULL on supported architectures
** Description changed: [Impact] The CONFIG_NO_HZ_FULL=y Kconfig option causes the kernel to avoid sending scheduling-clock interrupts to CPUs with a single runnable task, and such CPUs are said to be "adaptive-ticks CPUs". This is important for applications with aggressive real-time response constraints because it allows them to improve their worst-case response times by the maximum duration of a scheduling-clock interrupt. It is also important for computationally intensive short-iteration workloads: If any CPU is delayed during a given iteration, all the other CPUs will be forced to wait idle while the delayed CPU finishes. Thus, the delay is multiplied by one less than the number of CPUs. In these situations, there is again strong motivation to avoid sending scheduling-clock interrupts.

[Bug 1921411] [NEW] linux-azure: Install PMEM modules by default
Public bug reported:
[Impact]
Some workloads, for example SQL Server, require PMEM support from
different modules for performance reasons. Most of this modules are
included in the linux-modules-extra package but linux-azure doesn't
install it by default.
Move these modules to the linux-modules package so they are installed by
default: nd_blk.ko, nd_pmem.ko, device_dax.ko, dax_hmem.ko, kmem.ko,
dax_pmem.ko, dax_pmem_compat.ko, virtio_pmem.ko , nd_virtio.ko.
(Some modules are not available depending on the kernel version)
[Test Plan]
The modules listed below should be included in the linux-modules package
instead of in the linux-modules-extra package.
[Where problems could occur]
The additional modules shouldn't cause any troubles and in case of
problem they can be blacklisted or removed from linux-modules.

[Bug 1919154] [NEW] Enable CONFIG_NO_HZ_FULL on supported architectures
Public bug reported: [Impact] The CONFIG_NO_HZ_FULL=y Kconfig option causes the kernel to avoid sending scheduling-clock interrupts to CPUs with a single runnable task, and such CPUs are said to be "adaptive-ticks CPUs". This is important for applications with aggressive real-time response constraints because it allows them to improve their worst-case response times by the maximum duration of a scheduling-clock interrupt. It is also important for computationally intensive short-iteration workloads: If any CPU is delayed during a given iteration, all the other CPUs will be forced to wait idle while the delayed CPU finishes. Thus, the delay is multiplied by one less than the number of CPUs. In these situations, there is again strong motivation to avoid sending scheduling-clock interrupts. [Test Plan] In order to verify the change will not cause performance issues in context switch we should compare the results for: ./stress-ng --seq 0 --metrics-brief -t 15 Running on a dedicated machine and with the following services disabled: smartd.service, iscsid.service, apport.service, cron.service, anacron.timer, apt-daily.timer, apt-daily-upgrade.timer, fstrim.timer, logrotate.timer, motd-news.timer, man-db.timer. [Where problems could occur] Performance degradation might happen for workloads with intensive context switching. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Affects: linux (Ubuntu Hirsute) Importance: Undecided Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Hirsute) Importance: Undecided Assignee: Marcelo Cerri (mhcerri) Status: In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1919154 Title: Enable CONFIG_NO_HZ_FULL on supported architectures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1919154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1915051] Re: dkms-autopkgtest: Also select binary packages that depends on dkms for testing
Hi, Łukasz. I believe they were passing simply because the DKMS tests weren't being triggered. Those past tests were run with the old version of dkms- autopkgtest (from dkms) and thus only binary packages with names ending with "-dkms" were tested by it (whick is not the case for virtualbox- hwe). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915051 Title: dkms-autopkgtest: Also select binary packages that depends on dkms for testing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dkms/+bug/1915051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1916290] [NEW] Enforce CONFIG_DRM_BOCHS=m
Public bug reported: [Impact] In LP:#1872863 we started to build and ship the bochs-drm.ko driver again, however this config wasn't enforced and because of that derivatives didn't inherit. We should enforce CONFIG_DRM_BOCHS=m to avoid problem in the future and to let the derivatives update their configuration to include it or not. [Testcase] This should be a no-op for bionic:linux causing no differences for the current kernel. For derivatives, it will prompt the kernel engineer to update the config or to annotate it. [Regression Potential] Since it's no-op, there's no regression potential. ** Affects: linux (Ubuntu) Importance: Medium Assignee: Marcelo Cerri (mhcerri) Status: In Progress ** Affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916290 Title: Enforce CONFIG_DRM_BOCHS=m To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1916290/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
