okay so picture this: you're deep in the kernel, the IH ring buffer's read pointer is just sitting there being all stale, and literally nobody else is gonna fix it. that's this function. she's a little one but she ATE. ✨

🌸 NAME 🌸

iceland_ih_set_rptr — set the IH ring buffer rptr. that's it. that's the whole job. no cap. 💅

🦋 SYNOPSIS 🦋

void iceland_ih_set_rptr (struct amdgpu_device *adev , struct amdgpu_ih_ring *ih );

like, she takes two pointers and returns nothing. void queen. she doesn't need to give anything back, she's already that girl. 👑

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. this is your main character — the whole device herself. 🖥️✨
• ih — the IH ring buffer to set rptr on. yeah. that one. go set her rptr. 🌈

💖 DESCRIPTION 💖

Set the IH ring buffer rptr.

that's the description. that's literally what the manpage says. short, sweet, and to the point — it's giving minimalism, it's giving "i said what i said." the function sets the read pointer (rptr) of the IH ring buffer. obsessed. 🫶 no extra lore, no side quests, just rptr business. 🧚
