selftest_interrupt(9)

💖 selftest_interrupt(9) 💖

okay so bestie, welcome to the selftest_interrupt page — it lives in section 9 of the Kernel API Manual, and honestly? it's short, it's sweet, and it does exactly one thing. main character energy fr fr.

---

✨ NAME ✨

selftest_interrupt — Perform interrupt test. 🫶 that's it, that's the whole vibe.

---

🌸 SYNOPSIS 🌸

int selftest_interrupt (struct qed_dev *cdev );

no cap, that's the entire signature. one function, one pointer, one int coming back at you. iconic 💅

---

🦋 ARGUMENTS 🦋

• cdev — the Qed dev pointer. that's your device handle bestie, she's a struct qed_dev * and you literally cannot run this test without her 💜

---

🎀 RETURN 🎀

• 0 — slay, success ✨
• anything else — 😭 error, something went sideways, it's giving "not my finest moment"

so like, zero is the good number. anything that isn't zero means take the L and go investigate.

okay this is the part where the page goes absolutely feral with cross-references, and I am obsessed. first up, the kernel file:

• Kernel file ./include/linux/qed/qed_if.h 📁 — the header where all this lives, iykyk

and then the whole friend group, alphabetically-ish in the order the manpage gives them (do not come for me about the ordering, it's canon):

• selftest_memory(9)
• selftest_register(9)
• selftest_clock(9)
• selftest_nvram(9)
• can_link_change(9)
• set_link(9)
• get_link(9)
