ata_mode_string(9)

🌸 ata_mode_string(9) 🌸

okay bestie, so this is a kernel API manual page — like, a lil' reference card from the Kernel API Manual era — and today's main character is ata_mode_string. she converts xfer masks to strings. that's it. that's the whole gig. and honestly? she ate. 💅

✨ NAME ✨

ata_mode_string — convert xfer_mask to string 💖

🦋 SYNOPSIS 🦋

const char * ata_mode_string (unsigned int xfer_mask );

🎀 ARGUMENTS 🎀

• xfer_mask — a mask of bits that are supported, and here's the lil' plot twist bestie: only the highest bit counts. the rest are just... there. vibes only. lowkey decorative. 🫶

💜 DESCRIPTION 💜

so what she does is — she determines the string that represents the highest speed, aka the highest bit in modemask. that's the whole assignment. pick the top bit, hand back the name. iconic, no notes. ⭐

LOCKING: None. 🧚 like, zero locking. none. she's chill like that.

🌈 RETURN 🌈

she returns a constant C string representing the highest speed listed in mode_mask — or, if there's nothing to report, the constant C string "<n/a>". that's the fallback. that's the safe word. 🍓

ngl "<n/a>" is giving "she's not mad, she's just disappointed" energy 😭

👑 SEE ALSO 👑

okay so this is the part where the page just lists literally everyone in the building, and I mean everyone, so buckle up bestie — we're doing the full roll call, fr fr, no skipping, no "you get the idea", every single one: 💀

and that's the page bestie!! 🫶 this one lives in ./drivers/ata, dated October 2026, and it's titled ata_mode_string(9) — so like, if you ever need to cite her, that's the drip. go forth and convert those masks, mwah 💋🎀🦋
