ata_eh_set_mode(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for ata_eh_set_mode(9) — yes, the manual name is folded in right here, no cap. 💖

ata_eh_set_mode — Program timings and issue SET FEATURES - XFER

✨ SYNOPSIS ✨

the whole call looks like this, character for character:

int ata_eh_set_mode (struct ata_link *link , struct ata_device
**r_failed_dev );

🎀 ARGUMENTS 🎀

• link — link on which timings will be programmed
• r_failed_dev — out parameter for failed device

🦋 DESCRIPTION 🦋

Okay so this one is doing the most in the best way: it sets the ATA device disk transfer mode (PIO3, UDMA6, etc.). If ata_eh_set_mode fails, pointer to the failing device is returned in r_failed_dev.

Locking vibe check: LOCKING: PCI/etc. bus probe sem.

🌈 RETURN 🌈

0 on success, negative errno otherwise — periodt.
