📦 version 7.3.1, in nixpkgs unstable

✨ dce_v6_0_program_watermarks ✨

okay so bestie, welcome to the kernel API manual 💖 this one's a 9 page (that's the kernel section, iykyk) and it's called dce_v6_0_program_watermarks, which literally means program display watermarks. yes. watermarks. for your display. we love a niche function 🎀

🌸 SYNOPSIS 🌸

void dce_v6_0_program_watermarks (struct amdgpu_device *adev , struct
amdgpu_crtc *amdgpu_crtc , u32 lb_size , u32 num_heads );

that's the whole signature, no cap — it returns void, so don't go looking for a return value, it's giving "i do the work and i leave" 💅

👑 ARGUMENTS 👑

four of them, all mandatory, all iconic:

  • adev — amdgpu_device pointer. this is the device, the main character, the whole vibe.
  • amdgpu_crtc — the selected display controller. this is the one getting watermarked, periodt.
  • lb_size — line buffer size. yeah. that size. the line buffer one.
  • num_heads — number of display controllers currently in use. count 'em, bestie 🔥

🦋 DESCRIPTION 🦋

So here's the tea: this function calculates and programs the display watermarks for the selected display controller. and which generation are we talking? CIK. that's it, that's the whole summary — the docs keep it short and mysterious and honestly? main character energy 🫶

no extra lore in the original, so no extra lore from me — i'm not out here inventing behaviour, that's not the vibe 🙈
