🌸 amdgpu_devic...esume_phase3(9) 🌸

okay so we're in the Kernel API Manual, bestie — this is the page for amdgpu_device_ip_resume_phase3, and it's literally the third resume phase, hence the whole situation.

---

✨ NAME ✨

amdgpu_device_ip_resume_phase3 — run resume for hardware IPs. that's it, that's the whole function, and honestly? iconic.

---

🎀 SYNOPSIS 🎀

int amdgpu_device_ip_resume_phase3 (struct amdgpu_device *adev);

like look at her. one argument. no notes. 💅

---

🦋 ARGUMENTS 🦋

• adev — amdgpu_device pointer. that's the whole vibe check for this parameter, she's just a pointer to your amdgpu_device and she's doing her best. 🫶

---

💖 DESCRIPTION 💖

so this is the third resume function for hardware IPs — phase three, the finale, no cap. the list of all the hardware IPs that make up the asic gets walked, and the resume callbacks are run for all DCE. walking the list, running callbacks, main character energy fr fr.

what does resume even do? okay so resume puts the hardware into a functional state after a suspend, and it updates the software state as necessary. glow-up for your silicon. ✨

and bestie, this one is also used for restoring the GPU after a GPU reset — so she's not just for suspend, she moonlights as the reset recovery girlie too. multi-talented. 👑

returns 0 on success, negative error code on failure. so like, zero means slay, negative means 😭.

ngl if you get a negative error code back, that's your cue that something went wrong — that's literally what the return value is telling you.
