irq_domain_xlate_onecell(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay bestie, welcome to the irq_domain_xlate_onecell(9) page in the Kernel API Manual 💅. This function is literally the generic xlate for direct one cell bindings — that's the whole NAME vibe. No cap.

✨ SYNOPSIS ✨

int irq_domain_xlate_onecell (struct irq_domain *d , struct device_node
*ctrlr , const u32 *intspec , unsigned int intsize , unsigned long
*out_hwirq , unsigned int *out_type );

🎀 ARGUMENTS 🎀

  • d — the interrupt domain involved in the translation. main character of the domain situation.
  • ctrlr — the device tree node for the device whose interrupt is translated.
  • intspec — the interrupt specifier data from the device tree.
  • intsize — the number of entries in intspec.
  • out_hwirq — pointer to storage for the hardware interrupt number.
  • out_type — pointer to storage for the interrupt type.

🦋 DESCRIPTION 🦋

This is a Device Tree IRQ specifier translation function. It works with one cell bindings where the cell value maps directly to the hwirq number. That's it, that's the tea ☕ — one cell, direct mapping, no extra drama.
