[Bug 2008958] Re: please backport 0.21 to jammy
Hi all I have tested the "jammy" power-profiles-daemon 0.21-1~22.04.1 package on an iMac12,2 which comes with an Intel(R) Core(TM) i5-2500S CPU @ 2.70GHz running Kubuntu 22.04 LTS. Everything seems good and I think it now runs somewhat cooler. The package also installs fine at an ancient iMac5,1 which runs Lubuntu 22.04 LTS. This Apple computer comes with an Intel(R) Core(TM)2 T7400 CPU @ 2.16GHz. But on that model there is no effect noticeable. Most likely this is due a special Apple config problem of the Radeon GPU. The "power tables" are not present in the firmware and because of this the GPU is running always on max performance. Whatever, that's a different topic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2008958 Title: please backport 0.21 to jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/power-profiles-daemon/+bug/2008958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've tested the jammy upload against two AMD Phoenix laptops and everything is working as I would expect. However; I don't think it's appropriate to add the verification-done- jammy tag until we have some information from people on Intel machines to ensure we didn't cause any unintended side effects. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2008958 Title: please backport 0.21 to jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/power-profiles-daemon/+bug/2008958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Dimitri, or anyone else affected, Accepted power-profiles-daemon into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/power-profiles- daemon/0.21-1~22.04.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: power-profiles-daemon (Ubuntu Jammy) Status: Confirmed => Fix Committed ** Tags added: verification-needed verification-needed-jammy ** Changed in: power-profiles-daemon (Ubuntu Mantic) Status: Confirmed => Fix Committed ** Tags added: verification-needed-mantic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2008958 Title: please backport 0.21 to jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/power-profiles-daemon/+bug/2008958/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2008958] Re: please backport 0.21 to jammy
** Description changed: [ Impact ] power-profiles-daemon has the ability to make drastic improvements to the power consumption of machines. This increases the likelihood of them passing energy certifications such as Energy Star. On AMD laptops the following improvements are made: * Tune the platform cTDP using the ACPI platform profile drivers. * Tune the CPU using the amd-pstate EPP driver (kernel 6.5 or newer) * Tune the backlight using AMD ABM (kernel 6.8 or newer) * Tune the EPP dynamically based on AC vs battery On Intel laptops the following improvements are made: * Tune the CPU using the intel-pstate EPP/EPB driver * Tune the EPP dynamically based on AC vs battery As Ubuntu 22.04 has kernel 6.5 and will later get kernel 6.8, many of the improvements specifically for AMD laptops can apply. [ Test Plan ] Check for visual "performance issues" on battery using a web browser. Verify correct EPP targets are selected (balance_power on battery balance_performance on AC). Verify that changing to power-saver and performance profiles work properly. - - The below significant bugfixes are implemented, which would enable more - power & energy efficient modes on our supported laptops, as well as - enable for the kernel default to change. [ Where problems could occur ] There is a very thorough integration test suite distributed with power- profiles-daemon. This covers combinations of kernels and hardware that are seen in Ubuntu. It is reported upstream that some "old" Intel systems don't handle balance_power effectively and can cause skipped frames. This should be looked for explicitly when testing. It is possible that some users would prefer the increased performance instead of efficiency that will be available on a laptop in battery mode. They will need to manually change to performance mode to get that performance. [ Other info ] Frame.work has been suggesting to their AMD laptop users to use a backported release on this PPA https://launchpad.net/~superm1/+archive/ubuntu/ppd since Framework 13 AMD and Framework 16 AMD launched. There have been no reports of bugs on the release on this PPA. Full upstream changelog is below. 0.21 Since this release power-profiles-daemon is battery-state aware and some drivers use a more power efficient state when using the balanced profile on battery. In particular both the AMD and Intel P-State drivers will use the balance_power EPP profile, while for Intel one we also set the energy performance bias to 8 (instead of 6). This release also contains various fixes for the powerprofilesctl command line tool when using the launch or version commands. The tool is now better documented as we generate a manual page for it (if python3-argparse is installed) and bash completions. We're even generating the ZSH completions, but the install path must be provided. The daemon command line interface has been improved for debugging, so use --help-debug for further information. The systemd service lockdown settings have been restricted even more. Various code optimizations. 0.20 This release adds support for multiple power-profiles-daemon drivers to load simultaneously. This notably allows both CPU based control with amd-pstate or intel-pstate as well as ACPI platform profile based control. This release also adds support for the amdgpu panel power savings which uses dedicated hardware in systems with integrated Radeon graphics to decrease panel power consumption when the system is on battery. 0.13 This release adds support for the AMD P-State driver that's been added to the 6.3 Linux kernel. This release also fixes mismatched profiles on some HP laptops and some miscellaneous bug fixes. 0.12 This release adds support for the Intel "Energy Performance Bias" feature, which can be used on hardware that doesn't have a platform_profile or doesn't support HWP. It will also be used to eke out a bit more performance, or power, on systems which already supported HWP. More information is available in the README. 0.11.1 -- This release stops power-profiles-daemon from modifying the cpufreq driver when driver when the user/administrator has chosen to disable the Intel P-State scaling governor (eg. forcing a passive operation mode). More information is available in the README. 0.11 This release fixes problems on Intel machines when the CPUs didn't support turbo at all, or the performance scaling governor was built as default in the kernel. It also adds better end-user documentation, fixes in the command-line tool to not cause bug report tools to popup on not-uncommon errors, and a bug fix for running on some systems with controllable charge speeds. -- You received this bug notification because you are a
