jpeg_v5_3_0...ing_set_wptr(9)

✨ jpeg_v5_3_0_dec_ring_set_wptr ✨

okay bestie, welcome to the Kernel API Manual 💖 you're about to meet the tiniest little function in the AMDGPU universe and honestly? she's iconic for it.

---

🌸 NAME 🌸

jpeg_v5_3_0_dec_ring_set_wptr — literally just set write pointer. that's it. that's the whole job. no cap. 🎀

---

🦋 SYNOPSIS 🦋

void jpeg_v5_3_0_dec_ring_set_wptr (struct amdgpu_ring *ring );

yes she returns void — she gives nothing back and she's thriving 💅

---

🫶 ARGUMENTS 🫶

• ring — an amdgpu_ring pointer 💫 that's the whole argument list, bestie. one (1) parameter. we love a low-maintenance queen.

---

🔥 DESCRIPTION 🔥

So what does she actually do? She commits the write pointer to the hardware. 🎯

like, the write pointer has been sitting there in software being all theoretical, and this function is the moment she goes "okay diva, you're real now" and sends it to the hardware. main character energy fr fr ✨
