💅 drm_crtc_check_viewport ✨

okay so bestie, welcome to the kernel API manual — this one's drm_crtc_check_viewport(9), and honestly? it's giving "tiny bouncer at the door of the display pipeline." 🎀 let's get into it.

---

🌸 NAME 🌸

drm_crtc_check_viewport — literally just checks that your framebuffer is big enough for the CRTC viewport. that's it. that's the whole vibe check. ✨

---

🦋 SYNOPSIS 🦋

int drm_crtc_check_viewport (const struct drm_crtc *crtc , int x , int y
, const struct drm_display_mode *mode , const struct drm_framebuffer *fb
);

yeah she takes five args and returns an int, no cap. 💅

🎀 ARGUMENTS 🎀

• crtc — the CRTC that the framebuffer is gonna be displayed on. main character energy, obviously. 👑
• x — x panning. yes, the letter. yes, lowercase. 🙈
• y — y panning. matching set with x, they're a duo. 🫶
• mode — the mode that the framebuffer will be displayed under. the whole aesthetic it's being styled for. 🌈
• fb — the framebuffer we're checking the size of. this is the one getting the vibe check. 🔥
