💖 jpeg_v2_5_dec_ring_get_rptr 💖

okay so bestie, welcome to the Kernel API Manual ✨ — today we're looking at jpeg_v2_5_dec_ring_get_rptr, and honestly? it's giving "tiny function, big main character energy." 🎀

🌸 NAME 🌸

jpeg_v2_5_dec_ring_get_rptr — get read pointer 🫶

like, that's literally it. it gets the read pointer. slay.

✨ SYNOPSIS ✨

uint64_t jpeg_v2_5_dec_ring_get_rptr (struct amdgpu_ring *ring );

so you hand it a ring and it hands you back a uint64_t. one in, one out. balanced. iconic. 💅

🦋 ARGUMENTS 🦋

  • ring — an amdgpu_ring pointer 💜 that's the whole vibe, that's the whole argument, there's exactly one (1) of them and it's a pointer to a struct amdgpu_ring.

🔥 DESCRIPTION 🔥

okay so what does it actually do? it returns the current hardware read pointer ✨ periodt. that's the entire thing. no cap, no hidden extras, no secret side quests. you ask it for the read pointer, it gives you the read pointer. obsessed. 👑

and the whole friend group it runs with (go say hi to all of them, they're all (9) sections iykyk):

💀 lowkey reminder that the read pointer is a hardware read pointer — this function isn't out here computing anything, it's just reporting what the hardware says. don't go expecting magic, bestie, expect a pointer value. 🙈

mwah 💋 that's the page! this lil cutie comes to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's filed under jpeg_v2_5_dec_ring_get_rptr(9) — go read the whole jpeg_v2_5.c family, they ate. 🌟🍓🧚
