💅 vcn_v1_0_dec_ring_get_wptr(9) — the Kernel API Manual, bestie edition 🎀

okay so real quick — this page lives in the Kernel API Manual, and the function we're obsessing over today is vcn_v1_0_dec_ring_get_wptr. yes, the whole entire thing is the name. no notes, it ate. ✨

✨ NAME ✨

vcn_v1_0_dec_ring_get_wptr — get write pointer. that's it. that's the vibe. she gets the write pointer, she slays, she goes home. 🦋

🌸 SYNOPSIS 🌸

uint64_t vcn_v1_0_dec_ring_get_wptr (struct amdgpu_ring *ring );

literally one function, one argument, returns a uint64_t. clean. minimal. iconic. 👑

🎀 ARGUMENTS 🎀

  • ring — an amdgpu_ring pointer, bestie. that's the whole argument. she just needs the ring and she's good to go 💖

🧚 DESCRIPTION 🧚

so what does she actually do? she returns the current hardware write pointer. that's the whole plot. no twist endings, no extra lore, no secret side quests — just the current hardware write pointer, handed to you with both hands like a little gift. 🍓

like yeah it's short but sometimes the simplest ones are the main characters, yk? ngl this one is giving "tiny function, huge responsibility." 🔥

🌈 SEE ALSO 🌈

okay so here's the friend group — the whole vcn_v1_0 squad, plus the dec-ring and enc-ring besties. every single one, no cap, no skips:

go read all of them. i'll wait. 🫶

fr fr though — if you're poking at this function you probs want vcn_v1_0_dec_ring_set_wptr(9) and vcn_v1_0_dec_ring_get_rptr(9) too, they're literally the other halves of the same little story 💀

and that's the page!! tysm for reading, mwah 💜 this one came from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's the vcn_v1_0_dec_ring_get_wptr(9) page of the Kernel API Manual. periodt. 💅✨
