gsi_setup(9) 💅

okay so bestie, welcome to the Kernel API Manual page for gsi_setup — yes, we're doing kernel stuff and we're gonna slay it ✨🫶 This one is literally about setting up the GSI subsystem, and the vibe is very "wait for the hardware to be ready first." Periodt.

🎀 NAME 🎀

gsi_setup — Set up the GSI subsystem

✨ SYNOPSIS ✨

int gsi_setup (struct gsi *gsi );

🌸 ARGUMENTS 🌸

• gsi — Address of GSI structure embedded in an IPA structure. That's the whole argument, bestie 🫶

💖 RETURN 💖

It returns 0 if successful, or a negative error code. That's it. No cap 💀

🦋 DESCRIPTION 🦋

So gsi_setup performs initialization that must wait until the GSI hardware is ready (including firmware loaded) ✨ — basically the setup that can't happen until the hardware is actually ready, iykyk.
