💫 ata_acpi_stm(9) — the kernel API manual, bestie edition 💫

okay so you're reading the ata_acpi_stm(9) page from the Kernel API Manual and honestly? you're about to eat. this is the one that makes the kernel go talk to ACPI's _STM and i'm literally obsessed 🎀

✨ NAME ✨

ata_acpi_stm — execute _STM. that's it. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

int ata_acpi_stm (struct ata_port *ap , const struct ata_acpi_gtm *stm
);

yes bestie, it takes two arguments and returns an int. short and iconic, no notes 💅

✨ ARGUMENTS ✨

  • ap — the target ATA port 🌸 like, the port we're doing all this for, main character energy fr fr
  • stm — the timing parameter that gets handed over to _STM ⏱️ this is the actual payload of the whole operation

✨ DESCRIPTION ✨

so what it does is — it evaluates _STM with the timing parameter stm. that's the whole plot. no plot twists. 🫶

LOCKING: EH context. periodt. don't come at it from anywhere else, iykyk 😭

✨ RETURN ✨

  • 0 — success, we ate 🔥
  • -ENOENT — happens when _STM doesn't exist. like, the thing you're looking for just isn't there 🙈
  • -errno — on failure, whatever the errno says 💀
