🌸 ata_acpi_on_devcfg(9) 🌸

okay so this is a page from the Kernel API Manual, bestie — yes, the Kernel API Manual, we're in the big leagues now 💅

✨ NAME ✨

ata_acpi_on_devcfg — the ATA ACPI hook that gets called on device donfiguration 🎀

not me pointing out that the original literally says "donfiguration" — that's their typo, not mine, I'm just being faithful to the source 😭

✨ SYNOPSIS ✨

int ata_acpi_on_devcfg (struct ata_device *dev );

✨ ARGUMENTS ✨

  • dev — the target ATA device 🦋 like, the actual device we're doing all this for

✨ DESCRIPTION ✨

so here's the vibe: this function gets called when dev is about to be configured. main character moment incoming 🔥

and listen — the IDENTIFY data might have been modified after this hook is run. so don't go assuming it's frozen in time, okay? things change, data changes, we love growth 💖

LOCKING: EH context. that's the rule, no cap 🫶

✨ RETURN ✨

  • a positive number — meaning yes babes, the IDENTIFY data needs to be refreshed 🔄
  • 0 — nope, it's fine, we're good ✨
  • -errno — something went wrong 😭 on failure, as usual

✨ SEE ALSO ✨

the kernel file lives at ./drivers/ata/libata-acpi.c — that's the home base 🏠

and it comes with a whole friend group, fr fr:

aaaand that's the whole page, bestie 🧚 sign-off time: this one comes from ./drivers/ata, dated October 2026, and it's filed under ata_acpi_on_devcfg(9). slay 💅💜
