amdgpu_devic...esume_phase1(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… amdgpu_device_ip_resume_phase1 β€” like, the first resume phase, bestie

okay so real quick β€” this is a page from the Kernel API Manual (yes, the kernel has its own manual, she's fancy πŸ’…) and it's all about waking your AMD GPU's hardware IPs back up. stay with me, it's actually so good.


✨ NAME ✨

amdgpu_device_ip_resume_phase1 β€” run resume for hardware IPs 🫢


🌸 SYNOPSIS 🌸

int amdgpu_device_ip_resume_phase1 (struct amdgpu_device *adev);

πŸŽ€ ARGUMENTS πŸŽ€

  • adev β€” an amdgpu_device pointer. that's it, that's the whole argument. she's low-maintenance πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

So this is the first resume function for hardware IPs. literally phase one, the opening act, the main character entrance πŸ‘‘

Here's the vibe: the driver walks the whole list of hardware IPs that make up the asic β€” the entire roster β€” and runs the resume callbacks for COMMON, GMC, and IH. just those three for this phase, no cap. the other IPs get their moment in the later phases ✨

What does "resume" even mean here? it means putting the hardware into a functional state after a suspend, and updating the software state as necessary so everybody's on the same page. communication is key in any relationship, including driver↔hardware πŸ’–

Oh and the plot twist: this function is also used for restoring the GPU after a GPU reset. so she's not just a wake-up call, she's also the recovery girlie πŸ”₯

Returns 0 on success, or a negative error code on failure. 😭


🌈 SEE ALSO 🌈

okay this list is LONG, grab a snack πŸ“ β€” the kernel file itself lives at:

./drivers/gpu/drm/amd/amdgpu/amdgpu_device.c

and then all the friends and neighbors:


ngl bestie, that SEE ALSO list is giving "she has a lot of friends and she's loyal to every single one" 🫢 don't skip it, iykyk.

aaand that's the page! sourced from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 β€” yeah she's from the future, we don't question it πŸ’€βœ¨ mwah, go read phase2 now πŸ˜˜πŸ’–
