sdma_v7_1_ring_emit_ib(9)
π sdma_v7_1_ring_emit_ib β a kernel API manual moment
okay so bestie, welcome to the Kernel API Manual entry for sdma_v7_1_ring_emit_ib(9). yes that's the whole title, yes it's a mouthful, no we're not shortening it, it's iconic like that π
β¨ NAME β¨
sdma_v7_1_ring_emit_ib β literally just schedules an IB on the DMA engine. that's the whole gig. π
π¦ SYNOPSIS π¦
void sdma_v7_1_ring_emit_ib (struct amdgpu_ring *ring , struct
amdgpu_job *job , struct amdgpu_ib *ib , uint32_t flags );
it returns void, meaning it gives you nothing back, and honestly? respect. it just does the thing and leaves. main character energy fr fr π
πΈ ARGUMENTS πΈ
ringβ theamdgpuring pointer. this is the ring we're talking about, bestie, it's giving "the venue" π€jobβ the job we pull thevmidfrom. it's literally there so we can retrievevmid, that's its entire purpose in this function's life πibβ the IB object we're about to schedule. our little star of the show βflagsβ unused. not "sometimes used", not "used for special cases", unused. it's just... there. decorative. a lil guy π«Ά
π DESCRIPTION π
schedule an IB in the DMA ring. that's it, that's the description. short, sweet, and to the point, and honestly we love a function that knows exactly what it is. no cap. π₯

like, the whole squad showed up. we stan a well-documented family tree π
ngl bestie, if you're reading a section 9 kernel API page at 3am, hydrate, stretch, and know that flags is still unused. it will always be unused. that's its journey π
that's a wrap, bestie!! π this cutie lives in ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and it's a Kernel API Manual page, sdma_v7_1_ring_emit_ib(9) β mwah, slay, go schedule some IBs responsibly πβ¨π¦
