ata_data_xfer_8bit(9)

💅 ata_data_xfer_8bit — like, the whole kernel API manual moment 🎀

okay bestie, so this is a page straight out of the Kernel API Manual about ata_data_xfer_8bit. sit down, hydrate, and let's get into it ✨

✨ NAME ✨

ata_data_xfer_8bit — transfer data by 8bit PIO 🦋

🌸 SYNOPSIS 🌸

unsigned int ata_data_xfer_8bit (struct ata_queued_cmd *qc , unsigned
char *buf , unsigned int buflen , int rw );

💖 ARGUMENTS 💖

• qc — the queued command. yeah. that one. 👑
• buf — the data buffer, where the bytes live 💫
• buflen — buffer length, i.e. how many bytes we're dealing with here 🔥
• rw — read/write. pick a lane, bestie 😌

🧚 DESCRIPTION 🧚

so what it does? it transfers data from/to the device data register by 8 bit PIO. that's the whole vibe. no cap. 💅

LOCKING: inherited from caller. so like, not its problem — whoever called it already handled that. periodt 🫶

lowkey important: the locking is inherited from the caller, so don't come for this function about it 🙈
