Phoronix reports on "an exciting post-Christmas patch series out on the Linux kernel mailing list" proposing "a new runtime standby ABI that is similar in nature to the 'Modern Standby' functionality found with Microsoft Windows..." Modern Standby is a low-power mode on Windows 11 for letting systems remain connected to the network and appear "sleeping" but will allow for instant wake-up for notifications, music playback, and other functionality. The display is off, the network remains online, and background tasks can wake-up the system if needed with Microsoft Modern Standby... "This series introduces a new runtime standby ABI to allow firing Modern Standby firmware notifications that modify hardware appearance from userspace without suspending the kernel," [according to the email about the proposed patch series]. "This allows userspace to set the inactivity state of the device so that it looks like it is asleep (e.g., flashing the power button) while still being able to perform basic computations..." Those interested can see the RFC patch series for the work in its current form, in particular the documentation patch outlines the proposed /sys/power/standby interface.
