💅 radeon_fence_seq_signaled 💅

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel, we're in the kernel now, and this little function is out here doing fence vibe checks for the radeon driver. no cap, it's a whole thing. let's get into it 🎀

✨ NAME ✨

radeon_fence_seq_signaled — the function that checks whether a fence sequence number has signaled. that's it, that's the whole job, and it does it flawlessly 💅

✨ SYNOPSIS ✨

bool radeon_fence_seq_signaled (struct radeon_device *rdev , u64 seq ,
       unsigned int ring );

so it hands you back a bool — true or false, iconic binary queen — and it takes three things: a rdev, a seq, and a ring. keep reading, i'll introduce you 💖

✨ ARGUMENTS ✨

  • rdev — the radeon device pointer 🖥️ like, the actual GPU device we're talking about here. everything happens in the context of this bad boy.
  • seq — the sequence number. your number. the one you're asking about. 🔢
  • ring — the ring index that the fence is associated with 💫 so we're not just checking a random number in the void, we're checking it on a specific ring.

✨ DESCRIPTION ✨

okay so here's the tea ☕ this function checks whether the last signaled fence sequence number is >= the sequence number you requested — and it does this on all asics, every single one, no exceptions, she's universal 🫶

it returns true if the fence has signaled (meaning the current fence value is >= the requested value) 💚

or it returns false if it has not signaled (meaning the current fence value is < the requested value) 💀 that's it, that's the whole mood.

lowkey important: this is a helper function for radeon_fence_signaled — so it's not out here doing solo main character work, it's the support system. still iconic though. 🧚

✨ SEE ALSO ✨

the kernel file lives right here, bestie: ./drivers/gpu/drm/radeon/radeon_fence.c — go read the source, it's giving open book 📖

and now, the whole friend group, everybody say hi 👋

and that's the page, periodt 🌈 this lil doc lives in ./drivers/gpu/drm/radeon, dated October 2026 — so yeah, mark your calendars, it's from the future and it ate 🔥💜
