💅 ata_change_queue_depth(9)

okay so this is a page from the Kernel API Manual (yes, the fancy kernel docs, we love her) and it's all about ata_change_queue_depth — the little helper that sets a device's maximum queue depth. short page, but she ate. let's get into it 🫶

✨ NAME ✨

ata_change_queue_depth — set a device maximum queue depth 🎀

🌸 SYNOPSIS 🌸

int ata_change_queue_depth (struct ata_port *ap , struct scsi_device
*sdev , int queue_depth );

like, that's the whole signature. three args, one int coming back at you. nothing more, nothing less. periodt. ✨

🦋 ARGUMENTS 🦋

  • ap — the ATA port of the target device 👑 that's your struct ata_port *, the port we're messing with.
  • sdev — the SCSI device we're configuring the queue depth for 🌈 it's a struct scsi_device *, don't get it twisted.
  • queue_depth — the new queue depth 💅 the actual number, an int, that's literally the whole point of calling this.

💜 DESCRIPTION 💜

so this is a helper — a little guy whose entire job is to set a device's maximum queue depth. that's it, that's the function. 🧚

the cute part? it's usable with both libsas and libata, so she's flexible, she's versatile, she's main character energy in two subsystems at once. ngl, iconic. 🔥

⭐ SEE ALSO ⭐

okay bestie, buckle up, because this is the long part — the kernel file is ./drivers/ata/libata-sata.c, and the related functions are:

that's the whole squad, no cap — go read them if you want the full lore 😭💖

aaaaand that's the page!! short and sweet, fr fr. this masterpiece lives under ./drivers/ata and it's dated October 2026, so mark your calendars bestie 🎀✨💅
