host1x_register(9)

🦋 host1x_register(9) 🦋

okay bestie, welcome to the Kernel API Manual page for host1x_register — yes, the manual name is folded right in here, and this function is literally the “make it official” moment for a host1x controller 💅

✨ NAME ✨

host1x_register — register a host1x controller 👑

🎀 SYNOPSIS 🎀

int host1x_register (struct host1x *host1x );

🌸 ARGUMENTS 🌸

• host1x — host1x controller. that’s the controller in question, no cap 🫶

💖 DESCRIPTION 💖

The host1x controller driver uses this to register a host1x controller with the infrastructure. that’s the whole vibe: the driver brings its controller to the infrastructure, and the infrastructure is like “noted, bestie.” ✨

Note that all Tegra SoC generations have only ever come with a single host1x instance, so this function is somewhat academic. literally one instance across every generation — so it’s giving “academic” more than “main character energy,” iykyk 😭 periodt.
