💅 dce_v6_0_line_buffer_adjust(9) — Kernel API Manual 💅

okay bestie, welcome to the Kernel API Manual ✨ this page is literally all about dce_v6_0_line_buffer_adjust(9), and it’s giving “tiny function, very specific display-controller job” energy. no cap, let’s get into it 🫶

---

💖 NAME 💖

dce_v6_0_line_buffer_adjust — set up the line buffer 🎀

---

✨ SYNOPSIS ✨

u32 dce_v6_0_line_buffer_adjust (struct amdgpu_device *adev , struct
amdgpu_crtc *amdgpu_crtc , struct drm_display_mode *mode , struct
drm_display_mode *other_mode );

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer, bestie 💖
• amdgpu_crtc — the selected display controller 👑
• mode — the current display mode on the selected display controller 🌈
• other_mode — the display mode of another display controller that may be sharing the line buffer 🦋

---

🦋 DESCRIPTION 🦋

So basically, this function sets up the line buffer allocation for the selected display controller (CIK) 💅 and then returns the line buffer size in pixels. periodt. that’s the whole vibe check: line buffer allocation setup + a u32 return with the size in pixels 🔥
