💅 sata_pmp_same_pmp(9)

okay so bestie, welcome to the Kernel API Manual — this one's a little function from the kernel's SATA port-multiplier corner and honestly? it's giving "tiny but iconic" ✨

🎀 NAME 🎀

sata_pmp_same_pmp — does new GSCR matches the configured PMP? like, is this the same PMP or not, iykyk

🦋 SYNOPSIS 🦋

int sata_pmp_same_pmp (struct ata_device *dev , const u32 *new_gscr );

🌸 ARGUMENTS 🌸

  • dev — the PMP device we're comparing against 🫶 that's our main character right there
  • new_gscr — the GSCR block of the new device, aka the fresh vibe we're checking against

💖 DESCRIPTION 💖

So the whole plot: we take new_gscr, compare it against dev, and figure out whether dev is the PMP described by new_gscr. that's it. that's the function. no cap 💅

LOCKING: None. nope, zero, nada — no locking happening here 🙈

⭐ RETURN ⭐

1 if dev matches new_gscr, 0 otherwise. literally just a yes-or-no situation, very binary of it tbh 🔥
