💅 mpc52xx_irqhost_xlate(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for mpc52xx_irqhost_xlate ✨ this is section 9, the big-girl kernel-dev section, and honestly? she's a little mysterious. let's get into it 🎀

---

🌸 NAME 🌸

mpc52xx_irqhost_xlate — translate virq# from device tree interrupts property 🦋

that's the whole name section, and yes, it's giving "I do exactly one thing and I do it iconically" 💅

---

✨ SYNOPSIS ✨

int mpc52xx_irqhost_xlate (struct irq_domain *h , struct device_node *ct
, const u32 *intspec , unsigned int intsize , irq_hw_number_t *out_hwirq
, unsigned int *out_flags );

look at that signature. six arguments. she's committed 🤭 returns an int, takes all of the above, periodt.

🫶 ARGUMENTS 🫶

okay so this is where things get a little unhinged — the manpage itself says every single one of these is -- undescribed --. not me making that up, that's literally what's in there 😭 so here's the honest list, no cap, no invented lore:

• h — -- undescribed -- 🙈
• ct — -- undescribed -- 🙈
• intspec — -- undescribed -- 🙈
• intsize — -- undescribed -- 🙈
• out_hwirq — -- undescribed -- 🙈
• out_flags — -- undescribed -- 🙈

not me reading the docs and finding out nobody wrote the descriptions 💀 the arguments are all real and listed right there in the synopsis, but the manual is out here leaving them blank. iykyk — if you need the deets, the source file below is your bestie, not this page 🫶

👑 SEE ALSO 👑

• Kernel file ./arch/powerpc/platforms/52xx/mpc52xx_pic.c 🔥 (yes, the whole path, go read it, she's the main character)
• mpc52xx_is_extirq(9)
• mpc52xx_irqhost_map(9)
• mpc52xx_init_irq(9)
