Analysis
This article discusses a proposed patch series for the Linux kernel that introduces a new runtime standby ABI, aiming to replicate the functionality of Microsoft Windows' 'Modern Standby'. This feature allows systems to remain connected to the network in a low-power state, enabling instant wake-up for notifications and background tasks. The implementation involves a new /sys/power/standby interface, allowing userspace to control the device's inactivity state without suspending the kernel. This development could significantly improve the user experience on Linux by providing a more seamless and responsive standby mode, similar to what Windows users are accustomed to. The article highlights the potential benefits of this feature for Linux users, bringing it closer to feature parity with Windows in terms of power management and responsiveness.
