okay so real talk, this is ata_acpi_exec_tfs(9) and it is lowkey the moment ACPI meets your ATA device and they exchange notes. it's giving "get the settings, then write the settings." slay.

✨ SYNOPSIS ✨

int ata_acpi_exec_tfs (struct ata_device *dev , int *nr_executed );

literally that's the whole signature. two args. gorgeous. no cap. 💅

🌸 ARGUMENTS 🌸

  • dev — the target ATA device 🎯 like, the actual device we're doing all this for. main character energy fr.
  • nr_executed — an out parameter for the number of executed commands. yes bestie, it's an out parameter — the function writes back into it so you know how many commands actually got executed. 🫶

🦋 DESCRIPTION 🦋

so what does it do? it evaluates _GTF and then executes the taskfiles that came back from it. that's it, that's the vibe. get the taskfile settings, then write them. iconic. ✨

LOCKING: EH context. 🚨 that's the lock context, keep it in mind, iykyk.

🔥 RETURN 🔥

  • the number of executed taskfiles on success — yay 🎉
  • 0 if _GTF doesn't exist (like, it just wasn't there, no drama, no error)
  • -errno on other errors 😭 so check your negative values okay
