sdma_v4_0_ring_get_wptr(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to sdma_v4_0_ring_get_wptr(9) 💖 this is a page from the Kernel API Manual, and honestly? it's short, it's sweet, and it delivers. no notes. let's get into it ✨

🌸 NAME 🌸

sdma_v4_0_ring_get_wptr — get the current write pointer

like, it goes and gets the write pointer. that's the whole job. she's employed, she's thriving 💅

✨ SYNOPSIS ✨

uint64_t sdma_v4_0_ring_get_wptr (struct amdgpu_ring *ring );

yup, that's it. uint64_t in, one struct amdgpu_ring * argument, no cap 🫶

🎀 ARGUMENTS 🎀

  • ring — amdgpu ring pointer. that's the ring you're handing over. she needs it. give her the ring. 💍

🦋 DESCRIPTION 🦋

Get the current wptr from the hardware (VEGA10+) 🔥

that is literally the entire description. "wptr" = write pointer, "hardware" = the actual silicon, and the parenthetical VEGA10+ is doing a lot of heavy lifting — so like, if you're on VEGA10 or newer, this is your girl. older stuff? not her era, iykyk 🙈

💜 SEE ALSO 💜

the whole friend group 💅 first up, the source file, in case you wanna read the raw tea:

  • ./drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c

and then the entire squad, all 28 of them, no one left behind:

ok that's the page!! mwah 💋 no warnings, no bugs, no exit statuses — she's a clean, low-drama queen.

and finally, the little sign-off: this whole thing lives in ./drivers/gpu/drm/amd/amdgpu, and this edition is dated October 2026 — so like, future girl summer 🌈 stay hydrated, read your manpages, and remember: it's giving kernel developer energy 👑💖
