ata_dev_read_id(9)

💖 NAME 💖

ata_dev_read_id — read ID data from the specified device. This page is from the Kernel API Manual, bestie, and it's lowkey iconic. ✨

---

🌸 SYNOPSIS 🌸

int ata_dev_read_id (struct ata_device *dev , unsigned int *p_class ,
       unsigned int flags , u16 *id );

---

💅 ARGUMENTS 💅

• dev — the target device, aka the one we're reading from. 🎯
• p_class — pointer to the class of the target device (may be changed). ⚠️
• flags — ATA_READID_* flags. 🚩
• id — buffer to read IDENTIFY data into. 📥

---

🦋 DESCRIPTION 🦋

Okay so ata_dev_read_id reads ID data from the specified device. It performs ATA_CMD_ID_ATA on ATA devices and ATA_CMD_ID_ATAPI on ATAPI devices. It also issues ATA_CMD_INIT_DEV_PARAMS for pre-ATA4 drives. 💫

FIXME: ATA_CMD_ID_ATA is optional for early drives and right now we abort if we hit that case. 😭

LOCKING: Kernel thread context (may sleep). 💤

---

🌈 RETURN 🌈

It returns 0 on success, -errno otherwise. Slay when it's 0, bestie. 🫶
