💅 cs5520_set_timings — bestie's guide to kernel API manual, section 9

okay so buckle up bestie, we're in the Kernel API Manual and this page is section 9, the function is cs5520_set_timings, and yes it's giving "small function, big responsibility" energy. it's literally four little things and a whole lot of hardware devotion. 🎀

✨ NAME ✨

cs5520_set_timings — program PIO timings 🫶

like. that's it. that's the whole name. she programs the PIO timings. iconic, honestly.

🌸 SYNOPSIS 🌸

void cs5520_set_timings (struct ata_port *ap , struct ata_device *adev ,
int pio );

ngl the signature is a whole vibe — it returns void, so no exit status to stress about, no surprise return value, nothing. she just does the thing. 💅

🦋 ARGUMENTS 🦋

okay so three arguments, and each one is doing its own little main-character moment:

  • ap — the ATA port, fr fr. this is the port you're working with.
  • adev — the ATA device. yep, the actual device sitting on that port.
  • pio — the PIO ID. that's your PIO mode identifier, bestie, don't lose it.

⭐ DESCRIPTION ⭐

so basically: this function programs the PIO mode timings for the controller according to the pio clocking table. that's the whole assignment. she looks at the table, she programs the timings, she moves on. leroy jenkins but make it ATA. 😭✨

no cap, that's exactly what the description says — the timings for the controller, per the pio clocking table. don't come for me with "is there more" because there isn't. the simplicity is the point. 👑

💜 SEE ALSO 💜

go look at these, iykyk:

⚠️ real talk: that file path is exactly ./drivers/ata/pata_cs5520.c — copy it character for character, don't get cute with it bestie 🙈

🧚 sign-off 🧚

and that's the whole page!! this one came out of ./drivers/ata and it's dated October 2026 — so like, future girl summer but for kernel docs. mwah, go program some timings, you're gonna slay 💖💅🍓
