qed_hw_stop_fastpath(9)

💅 qed_hw_stop_fastpath — the kernel API manual, bestie edition 🦋

okay so this is a page from the Kernel API Manual — yes, the kernel manual, we love her — and today's main character is qed_hw_stop_fastpath. Sit down, get comfy, we're learning ✨

✨ NAME ✨

qed_hw_stop_fastpath — the function you call incase slowpath is still required for the device, but fastpath is not. That's literally the whole vibe: device still needs slowpath, doesn't need fastpath anymore, so you stop the fastpath. Periodt 💅

🌸 SYNOPSIS 🌸

int qed_hw_stop_fastpath (struct qed_dev *cdev );

bestie it's giving "one argument, one return value, no drama" 🎀

🫶 ARGUMENTS 🫶

• cdev — Qed dev pointer. That's it, that's the whole argument list. She's lowkey minimal and we respect it 🦋

💖 RETURN 💖

Int. — yep, it returns an int, no cap. That's the entire documented return situation, and honestly? iconic 🙈

ngl the manpage is not giving us extra lore here — no error codes spelled out, so don't go inventing any, bestie 💀
