As per Intel "We discussed needing this version in 24.10 with Stephane [Verdy] and he agreed this is closest to what we will need to support LNL. Additional patches will need to be backported to 0.0.6 later. But at the very least we should get 0.0.6 as baseline for 24.10.".
As additional context for the package FFe: intel-lpmd is the low-power mode daemon that is used on newer hybrid architectures (Meteor Lake onwards) where LP-cores are present (and not only the E-cores and P-cores of Alder Lake etc). lpmd manages the transition to low-power mode via dbus and can provide significant energy savings on mobile platforms. On v0.0.4 onwards, several changes were introduced enhancing this energy-saving capabilities. For instance, enhancing HFI support allows the daemon to handle scheduling hints from the CPU. By being able to enter multiple power states, it can exploit the sleep depth-latency trade-off more effectively and reduce power without affecting user experience. Finally, handling work load type hints allows the daemon to selectively enter low-power mode with increased accuracy. Due to the changes outlined above, I believe that this package should be accepted for a FFe as it provides significantly better handling of low- power modes on recent Intel mobile processors. As the processors themselves are very recent, it is expected we might require more frequent exceptions while the tooling around the LP-cores stabilize. Finally, I reiterate that the package has no reverse dependencies apt-cache rdepends intel-lpmd intel-lpmd Reverse Depends: And it has been thoroughly validated by Intel. Furthermore, as this is exclusively an user-space tool, any regressions should only cause performance/power degradation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080973 Title: [FFe] Update lpmd to version 0.0.6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-lpmd/+bug/2080973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
