📦 version 7.3.1, in nixpkgs unstable

💖 sdma_v5_0_ring_get_wptr 💖

okay bestie, welcome to the Kernel API Manual, section 9 — this is the glow-up page for sdma_v5_0_ring_get_wptr, and yes she's a whole function, come on. ✨

🌸 NAME 🌸

sdma_v5_0_ring_get_wptr — literally just "get the current write pointer." that's the whole vibe. short, sweet, iconic. 🎀

🦋 SYNOPSIS 🦋

uint64_t sdma_v5_0_ring_get_wptr (struct amdgpu_ring *ring );

like, hand her a ring pointer and she hands you back a uint64_t. transactional queen. 💅

✨ ARGUMENTS ✨

  • ring — an amdgpu ring pointer. that's it. that's the whole gift. 🫶

💜 DESCRIPTION 💜

so what she does is: she gets the current wptr (write pointer, iykyk) straight from the hardware. 🔥 not from some cached little variable, not from vibes — the actual hardware, bestie.

and the hardware in question? NAVI10+. so if ur on that era of card, she's the main character of this operation. 👑

no cap, that's the entire description. she's efficient like that. 💅

🌈 SEE ALSO 🌈

the kernel file she lives in, for the curious:

  • ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c

and her whole extended friend group — every single one of them, no gatekeeping 🫶:

go read them all. i'll wait. 💀

and that's the page, bestie!! 🌟 it came to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — so yeah, she's got a timestamp and she's not afraid to use it. mwah 💋✨🍓
