ali_check_atapi_dma(9)

✨ ali_check_atapi_dma ✨

okay so bestie, welcome to the Kernel API Manual — section 9, function girlie ali_check_atapi_dma(9). this is genuinely a tiny little page but it's got main character energy anyway, let's go 🎀

---

💖 NAME 💖

ali_check_atapi_dma — the DMA check for most ALi controllers 🦋

like, not all of them. most. the way that distinction matters, iykyk.

---

🌸 SYNOPSIS 🌸

int ali_check_atapi_dma (struct ata_queued_cmd *qc );

that's it. that's the whole vibe. one function, one argument, returns an int ✨

---

🧚 ARGUMENTS 🧚

• qc — the command to complete. that's your struct ata_queued_cmd *, no cap 🫶

---

👑 DESCRIPTION 👑

so this is the function that gets called to decide whether commands should be sent by DMA or PIO. literally that's its whole job — it's the vibe check for your data path, and whichever way it decides, that's how the command travels 💅

no notes, honestly. iconic behaviour.

🌈 SEE ALSO 🌈

okay this is where it pops off, because the whole ALi family shows up 🍓 the kernel file is ./drivers/ata/pata_ali.c and it's giving ensemble cast:

• ali_20_filter(9)
• ali_fifo_control(9)
• ali_program_modes(9)

go read them all bestie, they're all in ./drivers/ata too 💜
