STRUCT ZYNQMP_PM_DOMAIN(9)

💖 struct zynqmp_pm_domain(9) 💖

okay so this is a page straight outta the Kernel API Manual, and bestie it's a tiny one but it's meticulous — we're talking about struct zynqmp_pm_domain, which is literally just a wrapper around struct generic_pm_domain. that's it. that's the whole vibe. a little cozy blanket around the generic power domain so Xilinx ZynqMP can do its thing 🦋

✨ NAME ✨

struct zynqmp_pm_domain — a wrapper around struct generic_pm_domain 🫶

✨ SYNOPSIS ✨

struct zynqmp_pm_domain {
    struct generic_pm_domain gpd;
    u32 node_id;
    bool requested;
 };

no cap, that's the whole struct. three members. she's lowkey minimalist 💅

✨ Members ✨

• gpd — the generic power domain itself. like, the actual generic power domain energy 👑
• node_id — a u32 holding the PM node ID that corresponds to the device inside the PM domain. it's giving "which node are we even talking about" 🔥
• requested — a bool that says whether the PM node mapped to the PM domain has been requested. true means yes bestie, false means not yet 🎀

✨ SEE ALSO ✨

• the kernel file ./drivers/pmdomain/xilinx/zynqmp-pm-domains.c — go read the source, iykyk 📖
• zynqmp_gpd_is_active_wakeup_path(9)
• zynqmp_gpd_power_on(9)
• zynqmp_gpd_power_off(9)
• zynqmp_gpd_attach_dev(9)
• zynqmp_gpd_detach_dev(9)

like, the whole friend group fr fr 🌸

and that's the tea, bestie 🍓 this absolute icon of a page comes from ./drivers/pmdomain/xilinx, dated October 2026 — so yeah, she's from the future and still serving main character energy. go forth and wrap your power domains, periodt 💜✨
