✨ vmw_kms_check_display_memory ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's page is vmw_kms_chec...splay_memory(9) (yes the title got truncated by the terminal, she's a long-name girlie, we still love her 🫶). Buckle up, we're doing a vibe check on display memory 💅

---

🌸 NAME 🌸

vmw_kms_check_display_memory — literally just validates the display memory required for a topology ✨ no cap, that's the whole gig 🎀

---

🦋 SYNOPSIS 🦋

int vmw_kms_check_display_memory (struct drm_device *dev , uint32_t
num_rects , struct drm_rect *rects );

---

💜 ARGUMENTS 💜

• dev — the DRM device, main character energy fr fr 👑
• num_rects — how many drm_rects live in rects 🔢
• rects — array of drm_rect representing the topology to validate, indexed by crtc index 🗺️✨

---

🍓 RETURN 🍓

0 on success — slay 💅 otherwise a negative error code 😭 (not slay)
