vcn_v2_5_dec_ring_set_wptr(9)

💅 vcn_v2_5_dec_ring_set_wptr(9) — from the Kernel API Manual, bestie ✨

okay so picture this: it's a kernel API manual page, the function is vcn_v2_5_dec_ring_set_wptr, and it lives in section 9 (iykyk — that's the kernel interface section, we love a section 9 moment 🎀). This is the whole entire page, no skips, no cuts.

✨ NAME ✨

vcn_v2_5_dec_ring_set_wptr — literally just sets the write pointer 🫶

---

🌸 SYNOPSIS 🌸

void vcn_v2_5_dec_ring_set_wptr (struct amdgpu_ring *ring );

It returns nothing (void, the strong silent type 💀) and it takes exactly one argument. That's it. That's the whole signature. Slay.

---

🦋 ARGUMENTS 🦋

• ring — an amdgpu_ring pointer. Yes bestie, that's the whole description. It's a pointer, it points at an amdgpu_ring, and it's the thing you're passing in. Nothing more in the source, so nothing more from me. 🙈

---

👑 DESCRIPTION 👑

Commits the write pointer to the hardware. That's the vibe check and it passed. ✨

Like, look at that list — the decoder ring's whole friend group, plus the encoder rings crashing the party. Full main character energy from top to bottom. 🌈

ngl the entire description is one single sentence and I respect the confidence 😭

and that's the page!! mwah 💋 — sourced from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, filed under vcn_v2_5_dec_ring_set_wptr(9), and yes the footer says the exact same title as the top because that's how manpages do. periodt. 🍓🧚💜
