phy_may_wakeup(9)

okay so bestie, welcome to phy_may_wakeup(9) — yes, that's the page, and it's from the Kernel API Manual. It is literally here to answer one tiny but important question: does this PHY have wakeup enabled? no cap. ✨

🎀 NAME 🎀

phy_may_wakeup — indicate whether PHY has wakeup enabled. It's giving "wakeup status check" and honestly that's the whole assignment. 💅

🌸 SYNOPSIS 🌸

bool phy_may_wakeup (struct phy_device *phydev );

One function, one argument, zero drama. 🫶

🦋 ARGUMENTS 🦋

• phydev — the phy_device struct. That's it, that's the argument, and it's the PHY device we're asking about. 👑

⭐ RETURN ⭐

It returns true/false depending on the PHY driver's device_set_wakeup_enabled setting if using the driver model, otherwise the legacy determination. So yeah: driver-model path uses that setting, and the fallback is the legacy determination. 🔥
