okay so bestie, welcome to the Kernel API Manual — yes that's the actual manual name and yes this page is short, but it's important, so let's give it the attention it deserves 💅

✨ NAME ✨

jpeg_v1_0_decode_ring_set_wptr — literally just sets the write pointer. that's her job. that's what she does 🎀

✨ SYNOPSIS ✨

void jpeg_v1_0_decode_ring_set_wptr (struct amdgpu_ring *ring );

✨ ARGUMENTS ✨

• ring — an amdgpu_ring pointer, bestie. that's the whole personality of this parameter 🦋

✨ DESCRIPTION ✨

So what does she actually do? She commits the write pointer to the hardware. that's it. that's the post. no cap, it's a one-liner of a description but it's the whole function 💖

no extra lore here — the manpage really is this brief 🫶

✨ SEE ALSO ✨

like, go look in the kernel file ./drivers/gpu/drm/amd/amdgpu/jpeg_v1_0.c first, she's the main character 🧚
