💅 amdgpu_devic...ait_for_idle(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of your fave kernel API manual page — it's amdgpu_devic...ait_for_idle(9) from the Kernel API Manual, and honestly? it's giving "small function, big responsibility." let's get into it 🫶

---

✨ NAME ✨

amdgpu_device_ip_wait_for_idle — literally just... wait for idle, no cap 💤

---

🌸 SYNOPSIS 🌸

int amdgpu_device_ip_wait_for_idle (struct amdgpu_device *adev , enum
       amd_ip_block_type block_type );

like, that's the whole vibe. you hand it a device and an IP block type and it goes "mmkay lemme check if that thing's chillin' yet" 🔥

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer, aka the main character of this whole story 👑
• block_type — the type of hardware IP you're checking on (SMU, GFX, UVD, etc.) — yes bestie, the "etc." is doing a lot of heavy lifting there but that's what the page says 💀

---

🦋 DESCRIPTION 🦋

so basically this function waits for the requested hardware IP to be idle — like, it's standing outside the door with its arms crossed until the IP stops doing stuff 🙈

it returns 0 for success 🎉 or a negative error code on failure 😭 (and yeah, negative error codes are the kernel's love language, iykyk).

ngl, no extra lore on which error codes — the page keeps it vague, and we're not about to make stuff up. periodt 💅
