vcn_v2_0_dec...g_insert_end(9)
π NAME π
okay so bestie, meet vcn_v2_0_dec_ring_insert_end β she's the girly whose whole job is literally insert a end command. that's it. that's the gig. β¨
she lives in the Kernel API Manual, so yeah, she's kind of a big deal in kernel circles π
π¦ SYNOPSIS π¦
void vcn_v2_0_dec_ring_insert_end (struct amdgpu_ring *ring );
that's the whole signature, no cap β void return (she gives nothing back, she's mysterious like that π
) and she takes exactly one thing: a struct amdgpu_ring * named ring.
π ARGUMENTS π
ringβ anamdgpu_ringpointer. that's literally the entire description okay π it's just. a pointer. to anamdgpu_ring. iconically minimal of the docs ngl.
π DESCRIPTION π
bestie. it's so simple it's almost poetic πΈ β she writes a end command to the ring.
that's it!! that's the whole description!! no secret lore, no hidden flags, no little gotchas hiding in the fine print. she takes the ring, she drops a end command into it, she leaves. main character energy, zero extra dialogue πβ¨
ngl the docs are giving "one line and a dream" here β everything you get is exactly what's written above, so don't go looking for extra behaviour that isn't documented π
π SEE ALSO π
the kernel file she's living in, rent free π:

like look at that roster π₯ insert_start, insert_nop, insert_end β the insert triplets ate and left no crumbs π
and that's the whole page, bestie!! mwah π she's filed under ./drivers/gpu/drm/amd/amdgpu, dated October 2026, from the Kernel API Manual β so if you ever forget her, you know exactly where to find her π§ββοΈπβ
