dev_pm_genpd_get_hwmode(9)

💅 dev_pm_genpd_get_hwmode — kernel API manual, bestie edition 🎀

Okay so this is a page from the Kernel API Manual fam — it's dev_pm_genpd_get_hwmode(9) and honestly it's a little one but it matters. Let's go ✨

---

✨ NAME ✨

dev_pm_genpd_get_hwmode — gets the HW mode setting for the device, periodt 💅

---

🦋 SYNOPSIS 🦋

bool dev_pm_genpd_get_hwmode (struct device *dev );

---

🌸 ARGUMENTS 🌸

• dev — the device whose current HW-mode setting you want fetched. That's it, that's the whole vibe check 🫶

---

💖 DESCRIPTION 💖

So this helper function lets consumer drivers fetch the current HW mode setting of their device. Like, their device — you're peeking at your own stuff, not being nosy 👑

The way this works is a whole trust situation: it is assumed that the users guarantee that the genpd wouldn't be detached while this routine is getting called. Like bestie, do NOT let it detach mid-call, that's the one rule 🙈

---

⭐ RETURN ⭐

Returns the HW mode setting of device from SW cached hw_mode. That's the whole return, no cap 🎀
