mpt_host_page_alloc(9)

💖 mpt_host_page_alloc — the glow-up page 💖

okay so bestie, we're deep in the Kernel API Manual today (yes, that manual, the kernel one, we're fancy now 🎀) and this little function is genuinely doing the most important thing: it's grabbing system memory for the fw — fw = firmware, iykyk. 🦋

---

✨ NAME ✨

mpt_host_page_alloc — allocate system memory for the fw

---

🌸 SYNOPSIS 🌸

int mpt_host_page_alloc (MPT_ADAPTER *ioc , pIOCInit_t ioc_init );

---

🎀 ARGUMENTS 🎀

• ioc — Pointer to pointer to IOC adapter. (yes, a pointer to a pointer, she's extra like that 💅)
• ioc_init — Pointer to ioc init config page.

---

💅 DESCRIPTION 💅

so here's the vibe check: if we already allocated memory in the past, then like… we just resend the same pointer. no need to be dramatic about it, we're not re-allocating, we're re-sending. iconic, honestly. 🔥

Returns 0 for success, non-zero for failure. that's it, that's the whole personality. 🫶
