✨ vkms_crtc_init(9) ✨

okay so this is a page from the Kernel API Manual, bestie, and it's literally all about vkms_crtc_init — the glow-up moment where a CRTC gets born into the VKMS world 💅 no cap, it's a constructor and it's iconic for it.

🎀 NAME 🎀

vkms_crtc_init — Initialize a CRTC for VKMS

like… that's the whole vibe. it makes a CRTC. for VKMS. slay.

---

🦋 SYNOPSIS 🦋

struct vkms_output * vkms_crtc_init (struct drm_device *dev , struct
drm_plane *primary , struct drm_plane *cursor );

so you call it, you hand it three things, and it gives you back a struct vkms_output * 🫶 that's the whole deal, fr fr.

---

🌸 ARGUMENTS 🌸

okay bestie let's go through what you're passing in, one by one, no skipping 👑

• dev — the DRM device that's associated with the VKMS buffer. it's giving "who do you belong to" energy and honestly? valid.
• primary — the primary plane you're attaching to the CRTC. main character plane, obviously 👑
• cursor — the plane you're attaching to the CRTC. yes queen, the cursor gets to come too 🖱️✨

lowkey important: primary is the primary plane, cursor is a plane — the wording is different in the original and I'm not about to lie to you about it 💀
