zynqmp_pm_in...pend_work_fn(9)

💖 zynqmp_pm_init_suspend_work_fn(9) 💖

okay so bestie, we're in the Kernel API Manual today and this page is literally about one tiny little function that does the cleanup shift for the ZynqMP power management interrupt. no cap, it's short, but she's iconic. let's go. 🦋

---

✨ NAME ✨

zynqmp_pm_init_suspend_work_fn — Initialize suspend 🌸

that's it. that's the whole name. short and sweet, like a good text back.

---

✨ SYNOPSIS ✨

void zynqmp_pm_init_suspend_work_fn (struct work_struct *work );

she returns void — nothing back, no receipts, just vibes — and she takes exactly one argument. periodt. 💅

---

✨ ARGUMENTS ✨

• work — Pointer to work_struct 🎀

that's the only thing she asks for, and it's a pointer to a struct work_struct. yes bestie, the classic workqueue thing. she's not picky, she just needs something to work with.

---

✨ DESCRIPTION ✨

so here's the tea: this function is the bottom-half of the PM callback IRQ handler. 🫶

like, the IRQ handler is out there doing main character energy in interrupt context, and then this function is the one that comes in afterward — the bottom-half — to handle the deferred part of the job. she's the "i got it from here babe" of the power management world. lowkey essential. ✨

bestie don't overthink it — the whole description is literally one line in the original, so we're keeping it that way. no invented lore, i promise. 🙈

✨ SEE ALSO ✨

go check these out, they're all in the same friend group 💜:

• the kernel file ./drivers/soc/xilinx/zynqmp_power.c — yes, the struct lives there, that's the address, go say hi
• zynqmp_pm_work_struct(9)
• struct zynqmp_pm_event_info(9)
• zynqmp_pm_subsystem_restart_work_fn(9)

like genuinely go read them, they're the rest of the saga. iykyk. 🌈
