radeon_switcheroo_set_state(9)

💖 NAME 💖

Okay bestie, welcome to the radeon_switcheroo_set_state(9) page — yes, that’s the manual name, and this is the Kernel API Manual moment. It’s giving set switcheroo state. Periodt. 💅

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• pdev — pci dev pointer. Literally the pci dev pointer, no cap.
• state — vga_switcheroo state. That’s the vga_switcheroo state, bestie.

🦋 DESCRIPTION 🦋

So this one is the callback for the switcheroo driver. Suspends or resumes the asics before or after it is powered up using ACPI methods. That’s the whole vibe — the asics get suspended or resumed around that ACPI-powered-up moment. 💅
