💖 ACPI_RAPIDSTART 💖

okay so bestie, welcome to acpi_rapidstart(4) — that's the Kernel Interfaces Manual page for the Intel Rapid Start Technology ACPI driver, and honestly? it's giving niche-but-iconic. ✨

🌸 NAME 🌸

acpi_rapidstart — the Intel rapid start technology ACPI driver. yes that's the whole name, she's lowkey understated like that 💅

🎀 SYNOPSIS 🎀

so if you wanna compile this driver into the kernel (main character energy, no modules), you drop this line into your kernel configuration file:

device acpi_rapidstart

or, if you'd rather load the driver as a module at boot time, you put this line in loader.conf(5):

acpi_rapidstart_load="YES"

pick your lane, both slay 🫶

🦋 DESCRIPTION 🦋

the acpi_rapidstart driver provides support for the Intel Rapid Start technology ACPI device interface. and like… note that this is only for the ACPI device interface, ok? that's the whole vibe. 🧚

it has _CID PNP0C02, which is exactly why it should be loaded at boot time — you gotta avoid it attaching to the acpi_sysresource driver. no cap, that part matters. ⚠️

⭐ SYSCTLS ⭐

the following sysctl(8) nodes are currently implemented:

  • dev.acpi_rapidstart.0.ffs — the rapid start flag. it's a bitwise OR of these:
    • 1 — enter Fast Flash Standby in RTC wake.
    • 2 — enter Fast Flash Standby in Critical Battery Wake enable.
  • dev.acpi_rapidstart.0.ftv — the Fast Flash Standby timer value, in minutes. ⏱️
