stmmac_pltfr_get_irq_array(9)

✨ stmmac_pltfr_get_irq_array(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 today we're looking at stmmac_pltfr_get_irq_array — like, the whole thing, fr fr, no skimming.

---

🌸 NAME 🌸

stmmac_pltfr_get_irq_array — reads the per-channel IRQs off a platform device. That's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

int stmmac_pltfr_get_irq_array (struct platform_device *pdev , const
       char *fmt , int *irqs , size_t num );

literally the whole signature, copied exactly, i do not play about code 🫶

---

💖 ARGUMENTS 💖

• pdev — the platform device. the main character of this whole operation 👑
• fmt — the IRQ name format string, like for example "tx-queue-d". yes that's the actual example, i'm not making it up ✨
• irqs — the array where the IRQ numbers get stored. the little home for the numbers 🏠
• num — the maximum number of IRQs to read. a hard cap, no overachieving allowed 🙈

---

🔥 RETURN 🔥

• 0 on success — slay 💅
• -EPROBE_DEFER if the IRQ is deferred — not a fail, just a "not yet bestie" situation ⏳
• -EINVAL on error — something's off, check ur inputs 😭

ok important detail, don't miss this one: missing IRQs are set to 0 and iteration stops at the first missing IRQ. like it doesn't skip ahead and keep looking, it just stops there. periodt. 🛑
