irq_domain_...twothreecell(9)

✨ irq_domain_translate_twothreecell(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie, and it's honestly kinda iconic — it's a (9) page, which is the section for kernel internals, so you know it's the real-deal stuff 💅

🎀 NAME 🎀

irq_domain_translate_twothreecell — the generic translate girlie for direct two-or-three-cell bindings. that's the whole vibe 🦋

🌸 SYNOPSIS 🌸

int irq_domain_translate_twothreecell (struct irq_domain *d , struct
       irq_fwspec *fwspec , unsigned long *out_hwirq , unsigned int *out_type
       );

💖 ARGUMENTS 💖

• d — the interrupt domain that's involved in the translation. she's the main character of this operation 👑
• fwspec — the firmware interrupt specifier we're translating, aka the thing you're feeding in 🍓
• out_hwirq — a pointer to storage for the hardware interrupt number. yes, you gotta hand her somewhere to put it 🫶
• out_type — a pointer to storage for the interrupt type. same deal, different output 💜

🦋 DESCRIPTION 🦋

so basically this is the firmware interrupt specifier translation function for two or three cell specifications ✨ and the whole point is that the parameter values map directly onto the hardware interrupt number and the type specifier. no cap, that's it — direct mapping, no weird little detours, no extra lore 💀

and that's the whole page, bestie 🧚 alright so real quick, the sign-off: this one lives under ./kernel/irq in the source, it's dated October 2026, and it's page irq_domain_...twothreecell(9) from the Kernel API Manual. go read the other ones, iykyk 💖✨
