💅 amdgpu_switcheroo_set_state — Kernel API Manual energy ✨

okay so bestie, welcome to the Kernel API Manual entry for amdgpu_switcheroo_set_state(9) — yes the section 9 is doing numbers, she's a kernel function, not one of your little userland commands 💅

✨ NAME ✨

amdgpu_switcheroo_set_state — sets the switcheroo state 🦋

Like, that's literally her whole job description and she's not sorry about it.

🌸 SYNOPSIS 🌸

void amdgpu_switcheroo_set_state (struct pci_dev *pdev , enum
vga_switcheroo_state state );

No cap, that's the whole signature. She returns void and takes two things. Periodt.

🎀 ARGUMENTS 🎀

  • pdev — the pci dev pointer, aka the little handle that says which device we're talking about 🫶
  • state — the vga_switcheroo state, i.e. the vibe we're setting it to ✨

💖 DESCRIPTION 💖

She's the callback for the switcheroo driver — iconic behavior honestly 👑

What she does: she suspends or resumes the asics before or after the thing gets powered up using ACPI methods. The way that she's just sitting there, being a callback, waiting for switcheroo to call her up… main character energy fr fr 🔥

So yeah: before/after power-up via ACPI → she handles the suspend/resume of the asics. That's it. That's the whole gig. Lowkey elegant, highkey essential 💜

👑 SEE ALSO 👑

First up, the source file, because obviously:
