💅 jpeg_v5_0_1_dec_ring_get_wptr — get write pointer ✨

okay so bestie, this is a kernel API manual page (yes, the 9 means section 9, it's giving kernel-doc energy 🎀). Let's get into it.

✨ NAME ✨

jpeg_v5_0_1_dec_ring_get_wptr — get write pointer 🖊️

---

🌸 SYNOPSIS 🌸

uint64_t jpeg_v5_0_1_dec_ring_get_wptr (struct amdgpu_ring *ring );

like, that's the whole signature, no cap. it hands you back a uint64_t and takes exactly one thing. slay.

---

🦋 ARGUMENTS 🦋

• ring — an amdgpu_ring pointer 🌀 (literally just a pointer to an amdgpu_ring, that's the whole vibe)

---

💖 DESCRIPTION 💖

Returns the current hardware write pointer. that's it. that's the function. it goes and gets the wptr and gives it to you 💫

lowkey iconic for how straightforward it is ngl.

like look at get_rptr and set_wptr right there at the end — they're literally siblings of this one, iykyk 🔥
