π sdma_v7_0_ring_emit_mem_sync(9) π
okay so bestie, we're in the Kernel API Manual today and the star of the show is sdma_v7_0_ring_emit_mem_sync β yes the header truncates it to sdma_v7_0_ri...mit_mem_sync(9) like it's too iconic for a full name, but we know her full name, we been knew π
β¨ NAME β¨
sdma_v7_0_ring_emit_mem_sync β flush the IB by graphics cache rinse πΈ
π SYNOPSIS π
void sdma_v7_0_ring_emit_mem_sync (struct amdgpu_ring *ring );
literally returns nothing (void, she gives nothing and slays doing it), takes exactly one arg, periodt π«Ά
π¦ ARGUMENTS π¦
ringβ amdgpu ring pointer π« that's it, that's the whole parameter list, she's a one-arg wonder and we respect it
π DESCRIPTION π
so what does she DO. she flushes the IB by graphics cache rinse. that's the whole vibe! the IB gets flushed, the graphics cache gets rinsed, and honestly? iconic. no cap, that's the entire documented behaviour, don't come for me for the short description, that's just what the page says π§

mwah π that's the page! brought to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's the sdma_v7_0_ri...mit_mem_sync(9) moment β go flush that IB and rinse that graphics cache, bestie, you got this ππ¦π
