✨ hpt372_filter(9) — kernel API manual, but make it make sense ✨

okay bestie, welcome to the Kernel API Manual entry for hpt372_filter 💅 this is a <rainbow>mode selection filter</rainbow> and yes it's as niche as it sounds, but we're gonna get through it together 🫶

---

🎀 NAME 🎀

hpt372_filter — literally a mode selection filter, that's the whole vibe 🌸

---

🦋 SYNOPSIS 🦋

unsigned int hpt372_filter (struct ata_device *adev , unsigned int mask
);

that's the signature, no cap, copy it exactly 👑

---

💖 ARGUMENTS 💖

• adev — the ATA device in question, the main character here 🎀
• mask — the mode mask, i.e. the little filter-y thing that does the filtering ✨

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ the Marvell bridge chips that live on the HighPoint SATA cards do not seem to play nice with UltraDMA modes 1, 2, and 3 — and honestly? not with any MWDMA modes either... 😭 those modes just don't seem to be supported well, and that's exactly why this filter exists 💀
