dce_v6_0_page_flip(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dce_v6_0_page_flip(9) — from the Kernel API Manual, bestie ✨

Okay so picture this: it's a kernel manual page, it lives in the Kernel API Manual, and its whole name is dce_v6_0_page_flip(9). Say it with me — it's giving lowkey unhinged naming convention, but she's iconic and she knows it 🎀

✨ NAME ✨

dce_v6_0_page_flip — the pageflip callback. that's it. that's the whole job. main character energy fr 💅

🌸 SYNOPSIS 🌸

void dce_v6_0_page_flip (struct amdgpu_device *adev , int crtc_id , u64
crtc_base , bool async );

yes bestie, she's void, she takes four args, and she does not return a thing. no cap 🤭

🦋 ARGUMENTS 🦋

  • adev — the amdgpu_device pointer. your little handle to the whole device, okay? 🫶
  • crtc_id — which crtc we're cleaning up the pageflip on.
  • crtc_base — the new address of the crtc. and ngl it's a GPU MC address, so don't go treating it like some casual system memory pointer 🙈
  • async — this is a bool, and it means asynchronous flip. as in, the flip is doing its own thing. live your truth ✨

💖 DESCRIPTION 💖

So what does she actually do? She does the actual pageflip — and yes, that's evergreen+, meaning evergreen and everything after it, periodt 👑

Here's the tea ☕: during vblank, we take the crtc lock and then we wait for the update_pending bit to go high. the way that bit just... needs to go high first 😭 when it does go high, we release the lock and let the double buffered update take place. that's the whole ritual, bestie.

And then — plot twist — she returns the current update pending status. yes even though the synopsis is void. that's what the page says, so that's what we're saying 💀

🔥 SEE ALSO 🔥

the kernel file lives right here, go be nosy:

./drivers/gpu/drm/amd/amdgpu/dce_v6_0.c

and here's the whole friend group — every single one of them, no skips, no cuts, we respect the full roster 🫡

like, that's a lot of bandwidth functions. she really said "bandwidth" and meant it 🌈

okay bestie real talk: this all comes from ./drivers/gpu/drm/amd/amdgpu, dated October 2026. so when you cite her, cite her correctly, iykyk 💜

mwah 💋 go flip some pages, you absolute icon 🧚‍♀️⭐
