💅 sdma_v5_0_ri...mit_mem_sync(9) — the it-girl of IB flushing

okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is this lil function page, sdma_v5_0_ri...mit_mem_sync(9) — yes the title is lowkey truncated in the header (the full name is down in NAME, don't worry, we got you 🫶). She's niche, she's kernel-level, and she literally just rinses the IB with the graphics cache and dips. Iconic behaviour, no notes.

🌸 NAME 🌸

sdma_v5_0_ring_emit_mem_sync — she flushes the IB by graphics cache rinse. that's the whole vibe. 💅

✨ SYNOPSIS ✨

void sdma_v5_0_ring_emit_mem_sync (struct amdgpu_ring *ring );

that's it. one argument. one purpose. she's not complicated, she's just focused. 🎀

🦋 ARGUMENTS 🦋

  • ring — amdgpu ring pointer. yeah. that's the argument. the amdgpu ring pointer. the ring. the ring. she takes a pointer to an amdgpu ring and that's the whole cast list. 🫶

💖 DESCRIPTION 💖

flush the IB by graphics cache rinse. 💫

that's the description, bestie. i'm not gonna pad it out and lie to you — there's genuinely nothing more on this page. the function flushes the IB, and it does it by way of a graphics cache rinse. that's the assignment. she understood the assignment. she was the assignment. periodt. 👑

🌈 SEE ALSO 🌈

okay so the "see also" section is like, the group chat of this file — nobody's here alone in ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c (that's the kernel file she lives in, for reference 💜). full roster, no one left out, we don't do that here:

like, that's twenty-six (26) whole other functions bestie, go read them, they're all in the same folder 🍓

ngl if you're here looking for extra options or environment variables — there aren't any. this page is short and she knows it. don't come for her. 🙈

and that's the page!! mwah 💋 this lil beauty lives under ./drivers/gpu/drm/amd/amdgpu and the version tag says October 2026 — so yeah, she's from the future, we don't question it, we just stan. 🧚💜 bye bestie, go flush something 💅✨
