fm10k_check_hang_subtask(9)

💅 fm10k_check_hang_subtask(9) — like, the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel, in the Kernel API Manual (that's the manual name, iykyk 🎀), and you've stumbled onto this little icon. let me give you the whole rundown, no cap.

🌸 NAME 🌸

fm10k_check_hang_subtask — the girl whose whole job is literally checking for hung queues and dropped interrupts 💀

---

✨ SYNOPSIS ✨

void fm10k_check_hang_subtask (struct fm10k_intfc *interface );

she returns void, she takes one arg, she does not miss 👑

---

🦋 ARGUMENTS 🦋

• interface — pointer to the device interface structure. that's it, that's the whole argument list, and honestly? she ate.

---

💖 DESCRIPTION 💖

okay so this function is giving dual purpose main character energy — she's out here serving two whole purposes at once:

1. First, she strobes the interrupt lines in order to make certain interrupts are actually occurring. like, hey bestie, are you awake? vibe check 🔔
2. Secondly, she sets the bits needed to check for TX hangs. setting bits, doing the work 💅

and as a result? we should immediately determine if a hang has occurred. immediately. periodt. no waiting around 🌈

💀 friendly reminder: this is kernel space, so play nice — she's out here strobing real interrupt lines and flipping real bits, not vibes.
