irq_domain_create_linear(9)

🌸 irq_domain_create_linear(9) 🌸

okay so bestie, welcome to the Kernel API Manual page for irq_domain_create_linear(9). This is the one where we allocate and register a linear revmap irq_domain, and honestly? iconic. 💅

✨ NAME ✨

irq_domain_create_linear — allocate and register a linear revmap irq_domain. no cap, that's the whole vibe. 🦋

🎀 SYNOPSIS 🎀

Here's the exact signature, bestie — don't let the line wraps scare you:

       struct irq_domain * irq_domain_create_linear (struct fwnode_handle
       *fwnode , unsigned int size , const struct irq_domain_ops *ops , void
       *host_data );

💖 ARGUMENTS 💖

• fwnode — pointer to the interrupt controller's FW node. yes, firmware node energy. ✨
• size — number of interrupts in the domain. that's the count, periodt. 🔢
• ops — map/unmap domain callbacks. the little handlers that do the mapping/unmapping thing. 🫶
• host_data — controller private data pointer. private data stays private, iykyk. 🙈

🌈 RETURN 🌈

Newly created irq_domain. that's it — fresh domain, newly created, slay. 👑
