✨ sata_pmp_eh_recover_pmp(9) ✨

okay so this is straight out of the Kernel API Manual bestie, and it's about rescuing a PMP 🫶 yes we're doing kernel-level rescue missions today, it's giving main character energy fr fr

💖 NAME 💖

sata_pmp_eh_recover_pmp — recover PMP 💅

🌸 SYNOPSIS 🌸

int sata_pmp_eh_recover_pmp (struct ata_port *ap , struct
       ata_reset_operations *reset_ops );

🎀 ARGUMENTS 🎀

  • ap — the ATA port that the PMP is attached to 🦋 like that's its home, its whole vibe
  • reset_ops — the set of reset operations you're gonna use, no cap, you gotta hand it the whole toolkit ✨

💅 DESCRIPTION 💅

So here's the tea: this bad boy recovers the PMP attached to ap. 🫶

The recovery procedure is somewhat similar to the one in ata_eh_recover, except — and this is the important part, bestie — reset should always be performed in a hard->soft sequence, and if recovery fails, the result is PMP detachment. 😭 like it literally just lets go. the drama.

LOCKING: Kernel thread context (may sleep). 💀 so don't you dare call this from somewhere that can't sleep, ok?

🌈 RETURN 🌈

  • 0 on success 🎉 slay
  • -errno on failure 🙈 it's giving error code

🔥 SEE ALSO 🔥

Kernel file ./drivers/ata/libata-pmp.c — go read it, iykyk 📖✨

ok that's literally the whole page, go forth and recover those PMPs responsibly 🧚‍♀️

soooo that's it bestie!! this one lives in ./drivers/ata, dated October 2026 in the Kernel API Manual 💜 mwah, ily, bye 🍓⭐
