Linux 6.14 Brings Some Systems Faster Suspend and Resume
Amid the ongoing Linux 6.14 kernel development cycle, Phoronix spotted a pull request for ACPI updates which "will allow for faster suspend and resume cycles on some systems."

"Wikipedia defines ACPI as "an open standard that operating systems can use to discover and configure computer hardware components" for things like power management and putting unused hardware components to sleep. Phoronix reports: The ACPI change worth highlighting for Linux 6.14 is switching from msleep() to usleep_range() within the acpi_os_sleep() call in the kernel. "The extra delay added by msleep() to the sleep time value passed to it can be significant, roughly between 1.5 ns on systems with HZ = 1000 and as much as 15 ms on systems with HZ = 100, which is hardly acceptable, at least for small sleep time values."
