sis_133_mode_filter(9)

💅 sis_133_mode_filter(9) 💅

okay so bestie, welcome to the sis_133_mode_filter page — it's a kernel API manual entry (section 9, the fancy "kernel internals" section, iykyk) and honestly it's a short one but it eats. let's get into it ✨

---

🌸 NAME 🌸

sis_133_mode_filter — the mode selection filter, aka the little vibe-checker that decides which transfer modes get to stay on the guest list 🎀

---

🦋 SYNOPSIS 🦋

unsigned int sis_133_mode_filter (struct ata_device *adev , unsigned int
mask );

literally that's the whole signature, no cap. she takes two things and hands you back an unsigned int 💖

---

✨ ARGUMENTS ✨

• adev — the ATA device in question, the main character of this whole operation 👑
• mask — the mask you receive, which she then manipulates and passes right back to you 🔁 (yes, she will be touching it, that's the whole point)

---

🔥 DESCRIPTION 🔥

Block UDMA6 on devices that do not support it.

that's it. that's the description. she shows up, she checks if the device can actually handle UDMA6, and if it can't? blocked. no UDMA6 for you, bestie 💀 it's giving bouncer-at-the-club energy and honestly we respect it 🫶
