💅 megasas_adp_...it_for_ready — Kernel API Manual, bestie edition 🎀

okay so hi!! welcome to the megasas_adp_...it_for_ready(9) page from the Kernel API Manual — yes the title is truncated with ... and no, we are not going to fix it, it's iconic, we respect it 🫶. The real full name of this function is megasas_adp_reset_wait_for_ready and she is a whole mood. Let's get into it ✨

---

🌸 NAME 🌸

megasas_adp_reset_wait_for_ready — kick off a chip reset and then wait for the controller to come to ready state. literally initiate + wait, that's the whole personality 💅

---

⭐ SYNOPSIS ⭐

int megasas_adp_reset_wait_for_ready (struct megasas_instance *instance
, bool do_adp_reset , int ocr_context );

bestie it returns an int, keep that in mind 👑

---

🦋 ARGUMENTS 🦋

• instance — the adapter's soft state. like, the whole vibe of this controller in one struct 💖
• do_adp_reset — if it's true, we do a chip reset. if not... we don't. no cap 🔥
• ocr_context — if this is being called from OCR context, it gets set to 1; otherwise it's 0. binary queen 👑

---

🧚 DESCRIPTION 🧚

So here's the tea 🍓: this function initiates a chip reset, and then it waits for the controller to transition to ready state. That's it, that's the function, and she does it flawlessly ✨

Meanwhile — and this is the important part — while all that's happening, the driver will block all access to PCI config space from userspace 😤 nobody's poking the PCI config while we're mid-reset, okay?? protective main character energy fr fr 🛡️

and that's the page!! 🎀 mwah 💋

sign-off time bestie: this little icon lives in ./drivers/scsi/megaraid, dated October 2026, and it's the megasas_adp_...it_for_ready(9) page, exactly as the footer says — truncated title and all, we stan a mysterious ellipsis 💜✨
