cdns_wdt_resume(9)

💖 cdns_wdt_resume — Kernel API Manual, but make it cute 🎀

Okay so bestie, we're in the kernel API manual section 9 today, and the star of the show is literally cdns_wdt_resume — the function that says "wake up babe, we're back" to your device. ✨

---

🌸 NAME 🌸

cdns_wdt_resume — Resume the device. That's it, that's the whole vibe. The device was napping (suspend era 😴) and now it's time to come back online. Main character energy returned. 👑

---

🦋 SYNOPSIS 🦋

int cdns_wdt_resume (struct device *dev );

Yep, that's the whole signature — copy it exactly like that, extra space before the closing paren and all, don't come for me, it's literally how it's written. 💅

---

🎀 ARGUMENTS 🎀

• dev — handle to the struct device structure. Like, this is your ticket to the device. Hand it over and the function knows who it's resuming. 🫶

---

⭐ RETURN ⭐

• 0 on success — slay, we're so back, everything worked. 💖
• errno otherwise — ngl, something went sideways, and the error code tells you what. 😭

🌈 SEE ALSO 🌈

Fr fr, go read these too, they're all in the kernel file ./drivers/watchdog/cadence_wdt.c, and they're all giving watchdog excellence:

• struct cdns_wdt(9)
• cdns_wdt_stop(9)
• cdns_wdt_reload(9)
• cdns_wdt_start(9)
• cdns_wdt_settimeout(9)
• cdns_wdt_irq_handler(9)
• cdns_wdt_probe(9)
• cdns_wdt_suspend(9) — the one that puts it to sleep, aka cdns_wdt_resume's other half 🥺

Lowkey reminder: this page lives under ./drivers/watchdog — that's the directory it's coming from, iykyk.

And that's the whole page, bestie! 💜 This lil' doc dropped October 2026, lives in the ./drivers/watchdog section of the source, and its version tag is literally just cdns_wdt_resume(9) — iconic, no cap. Go resume something. 🧚‍♀️🌸
