π amdgpu_fence_driver_hw_init(9) π
okay so bestie, welcome to the amdgpu_fence_driver_hw_init page β it's a kernel API manual entry, and honestly? it's a little baddie. let's get into it. π¦
β¨ NAME β¨
amdgpu_fence_driver_hw_init β literally just enables the fence driver for all possible rings. that's the whole vibe. π
πΈ SYNOPSIS πΈ
void amdgpu_fence_driver_hw_init (struct amdgpu_device *adev );
like, no return value, no drama, just vibes. π
π«Ά ARGUMENTS π«Ά
adevβ the amdgpu device pointer. that's your main character right there. π
π₯ DESCRIPTION π₯
so what it actually does: it enables the fence driver for all possible rings β and yes, that means across all asics. slay. β¨
but here's the tea β β not all asics have all rings. so instead of being messy about it, each asic will only start the fence driver on the rings it actually has, using amdgpu_fence_driver_start_ring. it's giving "know your limits, respect your limits." π
and it Returns 0 for success. π

and that's the page! π this little manual lives in ./drivers/gpu/drm/amd/amdgpu, and it's dated October 2026 β yes, future icon behavior, we love to see it. π bye bestie, go read some kernel source, iykyk π§ββοΈβ
