xgene_ahci_read_id(9)

✨ NAME ✨

okay so bestie, this is xgene_ahci_read_id(9) from the Kernel API Manual, and it is literally about reading ID data from the specified device. that's the whole name vibe: xgene_ahci_read_id — read ID data from the specified device 🎀

🌸 SYNOPSIS 🌸

unsigned int xgene_ahci_read_id (struct ata_device *dev , struct ata_taskfile *tf , __le16 *id );

🦋 ARGUMENTS 🦋

• dev — device. that's the device bestie, the main character of this call 🫶
• tf — proposed taskfile. yes, the taskfile that's being proposed 💅
• id — data buffer. the data buffer where the ID data goes ✨

💖 DESCRIPTION 💖

This custom read ID function is required due to the fact that the HW does not support DEVSLP. no cap, that's the reason: the hardware literally does not support DEVSLP, so this custom read-ID function has to exist. it's giving required-workaround energy, but make it kernel API 😭🔥
