✨ amdgpu_devic...esume_phase2(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual 💅 — yes, the actual kernel, like the thing your whole computer runs on. the title got squished down to amdgpu_devic...esume_phase2(9) because apparently man page headers hate us, but the real name is right down below 👇

🌸 NAME 🌸

amdgpu_device_ip_resume_phase2 — run resume for hardware IPs 🫶

🎀 SYNOPSIS 🎀

int amdgpu_device_ip_resume_phase2 (struct amdgpu_device *adev );

🦋 ARGUMENTS 🦋

  • adev — amdgpu_device pointer. that's your GPU's little passport 🛂✨

💜 DESCRIPTION 💜

okay so this is the second resume function for hardware IPs. second. phase two. the sequel that actually slaps 🔥

here's the vibe: the list of all the hardware IPs that make up the asic gets walked — like, the whole squad, one by one — and the resume callbacks are run for all blocks except COMMON, GMC, and IH. those three are literally not invited to this party, no cap. 🙈

and what does "resume" even mean? it means putting the hardware into a functional state after a suspend, and updating the software state as necessary. it's giving glow-up after a nap 😴➡️👑

also, fun fact that is extremely not a fun fact: this function is also used for restoring the GPU after a GPU reset. so it's not just a morning routine, it's also the "we crashed, fix it" routine 💀

it returns 0 on success, and a negative error code on failure. that's it. that's the whole reporting system. negative error code, my beloved 😭

⭐ the whole entire friend group

like, that's seventy-three functions. seventy-three. that's not a see-also, that's a whole contact list 💀 but every single one of them is here, bestie, i would never do you like that 🫶

and that's the page!! 🎀 catch you in the ./drivers/gpu/drm/amd/amdgpu directory, October 2026, same bat-time same bat-channel — stay iconic, stay resumable ✨💅
