vmw_du_crtc_duplicate_state(9)

✨ NAME ✨

okay so bestie, this is the vmw_du_crtc_duplicate_state(9) page from the Kernel API Manual — and the name is literally doing the most: vmw_du_crtc_duplicate_state means duplicate crtc state. 💖

---

🎀 SYNOPSIS 🎀

here's the signature, copied exactly because we do not play with code:

struct drm_crtc_state * vmw_du_crtc_duplicate_state (struct drm_crtc
*crtc );

---

💅 ARGUMENTS 💅

• crtc — a DRM crtc. that's the whole argument, periodt. it's the crtc whose state is getting duplicated. ✨

---

🌸 DESCRIPTION 🌸

okay so vmw_du_crtc_duplicate_state allocates and returns a copy of the crtc state for the specified crtc. and it's not just one little corner of the state — it's both the common state and the vmw-specific state. Together. In one copy. Iconic. 💅

---

🦋 RETURN 🦋

you get back the newly allocated crtc state. that's the main character right there, and it slays. 👑

if it fails, you get NULL. 😭 not a vibe, but that's the failure case, ngl.
