evergreen_page_flip(9)

💅 evergreen_page_flip — pageflip callback

okay so this is evergreen_page_flip(9) from the Kernel API Manual, and bestie, it's literally the little function that makes your screen actually flip the page. iconic behaviour, no cap. 🦋

✨ SYNOPSIS ✨

void evergreen_page_flip (struct radeon_device *rdev , int crtc_id , u64
crtc_base , bool async );

like, that's the whole signature. she's not complicated, she just works. 🎀

---

🌸 ARGUMENTS 🌸

• rdev — a radeon_device pointer. yep, the radeon device. that's the girl. 💜
• crtc_id — the crtc to cleanup pageflip on. very "which one of y'all" energy.
• crtc_base — the new address of the crtc, and it's a GPU MC address btw, not like a regular pointer, don't get it twisted. 🧚
• async — asynchronous flip. bool. she said "do it in the background, periodt." ⭐

---

🔥 DESCRIPTION 🔥

so what does she do? she triggers the actual pageflip by updating the primary surface base address (evergreen+). that's it. that's the whole gig. main character energy but make it a register write. 💅✨

like, this is the moment the flip actually happens. not a preview, not a "we'll get to it" — the real deal. 🫶
