🌸 dce_v10_0_line_buffer_adjust(9) 🌸

okay so bestie, we're in the Kernel API Manual, section 9 — the deep-lore kernel zone 💅 and this page is literally called dce_v10_0_line_buffer_adjust. (the header up top gets all squished and shy and shows it as dce_v10_0_li...uffer_adjust(9), but we know her real name ✨)

---

💖 NAME 💖

dce_v10_0_line_buffer_adjust — Set up the line buffer 🎀

---

✨ SYNOPSIS ✨

u32 dce_v10_0_line_buffer_adjust (struct amdgpu_device *adev , struct
amdgpu_crtc *amdgpu_crtc , struct drm_display_mode *mode );

---

🦋 ARGUMENTS 🦋

• adev — amdgpu_device pointer 👑 the whole device, the main character
• amdgpu_crtc — the selected display controller 🖥️ like, the specific one we're doing this for
• mode — the current display mode on the selected display controller 🌈

---

💀 DESCRIPTION 💀

So the whole vibe here is: setup up the line buffer allocation for the selected display controller (CIK). 🫶 That's it, that's the job.

And then it Returns the line buffer size in pixels. — yes bestie, it hands you back a number, u32, pixels, no cap 📏✨

ngl the header up top is truncated to dce_v10_0_li...uffer_adjust(9) — that's just the page header being dramatic, not a different function 🙈
