jpeg_v4_0_5...ing_get_rptr(9)

💖 jpeg_v4_0_5_dec_ring_get_rptr — Kernel API Manual, section 9 💖

okay bestie, welcome to the little corner of the kernel where JPEG rings live. this page is from the Kernel API Manual, and it's literally just about grabbing a read pointer. tiny function, big main character energy. let's get into it 🎀

---

✨ NAME ✨

jpeg_v4_0_5_dec_ring_get_rptr — get read pointer

that's it. that's the whole vibe. it gets the read pointer. 💅

---

🌸 SYNOPSIS 🌸

uint64_t jpeg_v4_0_5_dec_ring_get_rptr (struct amdgpu_ring *ring );

one function, one arg, returns a uint64_t. no cap. 🦋

---

🎀 ARGUMENTS 🎀

• ring — an amdgpu_ring pointer. yes, that's the whole description, and honestly? she said what she said. it's the ring you're asking about 🫶

---

✨ DESCRIPTION ✨

Returns the current hardware read pointer 💖

like... that's the function. it goes and gets the read pointer from the hardware and hands it back to you as a uint64_t. iconic behaviour, zero notes, periodt. 👑

notice how get_wptr and set_wptr are right there too? yeah, that's the pointer-to-pointer pipeline slay 💀
