vmw_kms_resume(9)

💅 vmw_kms_resume(9) — the kernel API manual page, bestie edition

okay so this is a section 9 kernel API manual page, and yes it's giving "tiny function, big responsibilities" energy. sit down, grab a 🍓, let's get into it.

✨ NAME ✨

vmw_kms_resume — re-enable modesetting and restore state 🫶

🌸 SYNOPSIS 🌸

int vmw_kms_resume (struct drm_device *dev );

🎀 ARGUMENTS 🎀

• dev — pointer to the drm device 💖

⭐ RETURN ⭐

• 0 on success, slay ✨
• a negative error code on failure 😭

🦋 DESCRIPTION 🦋

So here's the tea: the state gets resumed from a previous vmw_kms_suspend. That's the whole vibe — suspend happened, now we're bringing it back.

⚠️ no cap, this is important: it's illegal to call this function without a previous vmw_kms_suspend. like, do not. 🚫💀
