💖 vga_switcheroo_client_fb_set(9) 💖

okay so bestie, welcome to the Kernel API Manual — literally the group chat where the kernel tells you how to talk to the vga_switcheroo framebuffer situation. sit down, grab a strawberry 🍓, we're doing this.

✨ NAME ✨

vga_switcheroo_client_fb_set — set framebuffer of a given client. that's it, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

void vga_switcheroo_client_fb_set (struct pci_dev *pdev , struct fb_info
*info );

no cap, that's the whole signature. she's short, she's iconic, she returns void because she gives nothing back 💅

🦋 ARGUMENTS 🦋

• pdev — client pci device. like, the actual device we're talking about, your main character 🫶
• info — framebuffer. the fb_info, the screen situation, the whole look 👑

💜 DESCRIPTION 💜

Set framebuffer of a given client. and the way that this matters: the console will be remapped to this on switching. so when the switcheroo goes down, your console ends up on this framebuffer. that's the entire tea, fr fr 🔥

bestie this is the part where I sign off 🥹 the whole thing lives in ./drivers/gpu/vga, dated October 2026, and yes the page is literally called vga_switcher...lient_fb_set(9) — she got truncated mid-name and honestly? still slaying 💀✨

mwah, go set some framebuffers, ily, bye 🧚‍♀️💖
