💅 ssam_contro...load_from_of 💅

okay bestie so this is a page from the Kernel API Manual — yes, the kernel has lore too — and it's all about ssam_controller_caps_load_from_of. the shortened name up top is literally just ssam_contro...load_from_of(9) because manpage headers ran out of room, not because anyone's being shady ✨

🎀 NAME 🎀

ssam_controller_caps_load_from_of — loads controller capabilities from OF/DT. that's it, that's the whole job. she's a loader, she loads. periodt 💅

---

✨ SYNOPSIS ✨

int ssam_controller_caps_load_from_of (struct device *dev , struct ssam_controller_caps *caps );

like look at her. returns an int, takes two args, zero drama. iconic.

---

🫶 ARGUMENTS 🫶

• dev — a pointer to the controller device. lowkey the main character here — she's the device you're pulling info from 🎀
• caps — where to store the capabilities in. it's the basket, bestie. the caps go IN the caps. iykyk 🌸

ok real talk bestie: everything above is the actual documented content, i didn't invent a single syscall. go read the kernel file if you wanna see her in her natural habitat 🌈

and that's the whole vibe check 💀 this page came out of ./drivers/platform/surface/agg... (the abbreviated path, she's shy), with a date of October 2026, and the footer's repeating the title ssam_contro...load_from_of(9) one more time for the cheap seats. mwah 💋 go forth and load those caps 🦋👑
