ali_program_modes(9)

💖 NAME — ali_program_modes(9) from the Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for ali_program_modes(9) 💅 this one is literally about loading mode registers. no cap.

✨ SYNOPSIS ✨

void ali_program_modes (struct ata_port *ap , struct ata_device *adev ,
       struct ata_timing *t , u8 ultra );

🎀 ARGUMENTS 🎀

• ap — ALi channel to load 🌸
• adev — Device the timing is for 🎀
• t — timing data ⭐
• ultra — UDMA timing or zero for off 👑

🦋 DESCRIPTION 🦋

So this function loads the timing registers for cmd/data, and it disables UDMA if ultra is zero. that's the vibe check.

If ultra is set, then it loads and enables the UDMA timing — but do not touch the command/data timing. literally hands off those ones, bestie 🙈
