STRUCT PDC_REGS(9)

✨ struct pdc_regs — PDC Registers Location ✨

okay bestie, this is a page from the Kernel API Manual, and it's a short one — but it's lowkey important if you're poking at the Qualcomm PDC irqchip, so let's get into it 🫶

---

🌸 SYNOPSIS 🌸

struct pdc_regs {
    u32 irq_en_reg;
    u32 irq_cfg_reg;
    u32 irq_param_reg;
};

it's giving three little u32s holding register locations, and honestly? iconic. no cap. ✨

🎀 Members 🎀

so here's the breakdown of every member, one by one, because we do not skip details in this house 💅

• irq_en_reg — this one holds the location of the IRQ_ENABLE_BANK register. yes, the enable bank. the vibes are: "where do we turn interrupts on" 📍
• irq_cfg_reg — holds the location of the IRQ_CFG register. config energy fr fr ⚙️
• irq_param_reg — holds the location of the IRQ_PARAM register. the parameter one. she's the third member and she ate 💖

lowkey note: each of these is just a register location — that's the whole point of the struct. don't go expecting anything fancier, bestie 🙈

🦋 SEE ALSO 🦋

go check out the kernel file ./drivers/irqchip/qcom-pdc.c — and while you're in the neighborhood, here's the whole friend group 🫶

• struct pdc_irq_cfg(9)
• struct pdc_desc(9)
• qcom_pdc_gic_set_type(9)
• qcom_pdc_gic_secondary_set_type(9)

all of them live in ./drivers/irqchip, iykyk 🌈

and that's the whole page, bestie — short, sweet, and every single member accounted for 💜
