ACPI_RAPIDSTART(4)

💖 ACPI_RAPIDSTART 💖

okay bestie, so this is acpi_rapidstart(4), and it lives in the Kernel Interfaces Manual section. yes, kernel stuff, we're going there, and honestly? we're gonna slay it. 🧚

✨ NAME ✨

acpi_rapidstart — the Intel rapid start technology ACPI driver, no cap 💅

---

🌸 SYNOPSIS 🌸

so like, if you wanna compile this driver into the kernel (main character energy, permanently living in there), you drop this line into your kernel configuration file:

device acpi_rapidstart

or — and this is the lowkey easier route — you load it as a module at boot time, and for that you put this line in loader.conf(5):

acpi_rapidstart_load="YES"

pick your fighter, both are valid 🫶

---

🦋 DESCRIPTION 🦋

okay so the acpi_rapidstart driver gives you support for the Intel Rapid Start technology ACPI device interface. and bestie, I need you to hear this part: it's only for the ACPI device interface. that's it. that's the whole thing. not the rest of it, just that.

and here's the tea 🍵 — this thing has _CID PNP0C02, which means you should fr fr load it at boot time, otherwise it'll go and attach itself to the acpi_sysresource driver instead, and that is not the vibe we're going for. load it early, thank me later.

⭐ SYSCTLS ⭐

the following sysctl(8) nodes are currently implemented, and yes we're listing all of them:

• dev.acpi_rapidstart.0.ffs — the Rapid start flag. it's a bitwise OR of these bad boys right here:
  • 1 — Enter Fast Flash Standby in RTC wake.
  • 2 — Enter Fast Flash Standby in Critical Battery Wake enable.
• dev.acpi_rapidstart.0.ftv — Fast Flash Standby timer value, measured in minutes. tick tock ⏰
