💅 vcn_v2_5_enc_ring_get_rptr(9) — the Kernel API Manual, bestie edition 🎀

okay so real talk, we're deep in the Kernel API Manual today and this one page is about exactly one tiny little function that does exactly one tiny little thing. it's giving "small but mighty" energy and honestly? obsessed. 🦋

✨ NAME ✨

vcn_v2_5_enc_ring_get_rptr — the function that goes and gets the enc read pointer. that's it. that's the whole job. no cap. 💖

🌸 SYNOPSIS 🌸

uint64_t vcn_v2_5_enc_ring_get_rptr (struct amdgpu_ring *ring );

like, look at her. returns a uint64_t, takes one struct amdgpu_ring * named ring. clean, simple, iconic. she's not doing too much and honestly we respect that. 👑

🎀 ARGUMENTS 🎀

  • ring — an amdgpu_ring pointer. that's your ring bestie. that's the one. hand her over and we'll go look at her hardware read pointer. 🫶

🧚 DESCRIPTION 🧚

so what does it actually do? it returns the current hardware enc read pointer. literally that. the hardware's enc read pointer, freshly fetched, handed back to you as that uint64_t. no side quests, no surprises, just the pointer. slay. 💅

lowkey the most main-character thing about this function is how unbothered it is. it gets the pointer. it returns the pointer. periodt. ✨

🌈 SEE ALSO 🌈

if you wanna keep the vibe going, the whole squad lives in this kernel file:

  • ./drivers/gpu/drm/amd/amdgpu/vcn_v2_5.c 📁

and the rest of the friend group:

like yes, the dec ring has her own getters and setters, and yes, the enc ring has a get_wptr and a set_wptr too — but this page is the get_rptr one. know the difference, iykyk. 💜

and that's the whole page, bestie!! 🍓 this little cutie comes to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and she's filed under vcn_v2_5_enc_ring_get_rptr(9). mwah 💋 go get that read pointer. 🔥
