** Summary changed: - please backport 0.20 to jammy + please backport 0.21 to jammy
** Description changed: 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. + + 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 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
