hfi1_init_dd(9)

💖 NAME 💖

okay so bestie, gather round: this is the tea on hfi1_init_dd(9) from the Kernel API Manual — and the name is literally hfi1_init_dd, aka Initialize most of the dd structure. no cap, that's the whole name vibe 💅

✨ SYNOPSIS ✨

int hfi1_init_dd (struct hfi1_devdata *dd );

🎀 ARGUMENTS 🎀

• dd — the dd device. yep, that's the whole argument, bestie 🫶

🦋 DESCRIPTION 🦋

okay so here's the situation: this function is global, and it's called directly at init to set up the chip-specific function pointers for later use. literally setting the stage at init time so future stuff has what it needs ✨
