ti_sci_intr_...domain_alloc(9)

💅 ti_sci_intr_irq_domain_alloc — bestie's guide to the kernel API manual ✨

okay so this is a page straight out of the Kernel API Manual, and it's lowkey the whole saga of one little function. the name? ti_sci_intr_irq_domain_alloc. say it three times fast, i dare you 😭 she's iconic, she's niche, she allocates interrupt router IRQs and she does NOT miss.

🎀 NAME 🎀

ti_sci_intr_irq_domain_alloc — literally just: Allocate Interrupt router IRQs 🦋 that's the whole vibe. no cap, that's her job description.

---

✨ SYNOPSIS ✨

int ti_sci_intr_irq_domain_alloc (struct irq_domain *domain , unsigned
int virq , unsigned int nr_irqs , void *data );

bestie she takes four things and she gives you back an int. that's the whole shape of her. main character energy fr fr 👑

---

🌸 ARGUMENTS 🌸

okay so let's do a little vibe check on each of her params, one by one, no skipping 💖

• domain — this one points at the interrupt router IRQ domain. she's the setting, the stage, the location of the whole situation 🎀
• virq — the corresponding Linux virtual IRQ number. yes bestie it's a virtual number, it's giving digital realness 🌈
• nr_irqs — the continuous irqs to be allocated. plural! continuous!! a whole little squad of them 🫶
• data — a pointer to the firmware specifier. idk what's in there but she knows 👀🔍

---

🦋 DESCRIPTION 🦋

so what does she do? literally:

Return 0 if all went well else appropriate error value.

that's it. that's the whole tea 🍓 0 = slay, we ate, everything worked. anything else = an appropriate error value, which is a very polite way of saying "girl something went wrong and she's telling you about it" 💀 not me refreshing my whole personality over a return code.
