asd_init_chip(9)

💅 asd_init_chip(9) — initialize the chip 💅

okay bestie, welcome to the asd_init_chip(9) page from the Kernel API Manual — we're doing the chip reset thing today and it's lowkey iconic ✨

---

🌸 NAME 🌸

asd_init_chip — initialize the chip. That's the vibe check: this is the function that gets the chip initialized, periodt.

---

✨ SYNOPSIS ✨

the signature ate and left no crumbs, keep it exactly like this:

int asd_init_chip (struct asd_ha_struct *asd_ha );

---

🎀 ARGUMENTS 🎀

• asd_ha — pointer to host adapter structure. literally the host adapter struct pointer, no extra lore 🫶

---

🦋 DESCRIPTION 🦋

This function is the full send: it hard resets the chip, disables HA interrupts, downloads the sequencer microcode (the page spells it sequnecer, and honestly we respect the lore 💀), and starts the sequencers. no cap, that's the whole sequence.

🚨 important: it does not enable HA interrupts for you. The caller has to explicitly enable HA interrupts with asd_enable_ints(asd_ha). don't forget, bestie 😭
