radeon_fence_process(9)
π radeon_fence_process(9) β from the Kernel API Manual, bestie β¨
okay so real talk, this one's from the radeon_fence_process(9) page in the Kernel API Manual and it's honestly short but it matters, so let's get into it π«Ά
πΈ NAME πΈ
radeon_fence_process β literally just: process a fence. that's the whole gig. no cap. β¨
π SYNOPSIS π
void radeon_fence_process (struct radeon_device *rdev , int ring );
that's it. two args, no return value (it's a void, so it gives you nothing back β very demure, very mindful π).
π¦ ARGUMENTS π¦
rdevβ aradeon_devicepointer π like, the actual radeon device we're talking about here.ringβ the ring index that this fence is associated with π so you gotta know which ring you're talking about, iykyk.
π DESCRIPTION π
okay so what does it DO π it checks the current fence value, and if the sequence number has increased, it wakes the fence queue. that's the whole vibe. and yes β this goes for all asics, no exceptions, everyone's invited to the party π π₯
ngl, this is one of those "small function, big consequences" situations β it's the thing that notices "oh we moved forward" and goes and wakes everybody up πΈ
β SEE ALSO β
the kernel file lives right here in ./drivers/gpu/drm/radeon/radeon_fence.c π and here's the whole fence friend group, they all show up together:

and that's the whole page, bestie π this came out of ./drivers/gpu/drm/radeon, dated October 2026, and it's radeon_fence_process(9) β go forth and process those fences, you absolute icon πβ¨π
