STRUCT PRUSS_INTC(9)

💖 struct pruss_intc: PRUSS interrupt controller structure 💖

✨ NAME ✨

struct pruss_intc — PRUSS interrupt controller structure. This is the struct pruss_intc(9) page from the Kernel API Manual, and bestie, it’s literally the controller’s whole data vibe wrapped up in one C struct 💅✨

🌸 SYNOPSIS 🌸

       struct pruss_intc {
           struct pruss_intc_map_record event_channel[MAX_PRU_SYS_EVENTS];
           struct pruss_intc_map_record channel_host[MAX_PRU_CHANNELS];
           unsigned int irqs[MAX_NUM_HOST_IRQS];
           void __iomem *base;
           struct irq_domain *domain;
           const struct pruss_intc_match_data *soc_config;
           struct device *dev;
           struct mutex lock;
        };

💅 Members 💅

okay so these are the members, and we are doing all of them, no skipping, no cap:

• event_channel — current state of system event to channel mappings. The receipts for where every system event is headed 🫶
• channel_host — current state of channel to host mappings. Keeping track of which channel is chatting with which host 💌
• irqs — kernel irq numbers corresponding to PRUSS host interrupts. The actual irq number lineup, looking iconic 🔥
• base — base virtual address of INTC register space. The address where the register space starts, periodt 📍
• domain — irq domain for this interrupt controller. This controller’s irq-domain situation, very main character energy 👑
• soc_config — cached PRUSS INTC IP configuration data. Cached config data, sitting there being useful 🌸
• dev — PRUSS INTC device pointer. The device pointer for this PRUSS INTC, slay 🎀
• lock — mutex to serialize interrupts mapping. The mutex that keeps interrupts mapping from getting messy, thank u 💀
