megasas_create_frame_pool(9)

✨ NAME ✨

okay bestie, this is megasas_create_frame_pool from the Kernel API Manual 💖 — and the tiny iconic summary is literally: Creates DMA pool for cmd frames. That’s the whole vibe. No cap. 🎀

💅 SYNOPSIS 💅

int megasas_create_frame_pool (struct megasas_instance *instance );

🎀 ARGUMENTS 🎀

• instance — the adapter soft state. That’s it, bestie: one argument, and it’s the adapter’s soft state. 🫶

🦋 DESCRIPTION 🦋

So every command packet has an embedded DMA memory buffer, right? That buffer is used for filling the MFI frame and the SG list that immediately follows the frame — literally adjacent, main-character energy. ✨

This function creates those DMA memory buffers for each command packet by using the PCI pool facility. Slay. That’s the function’s whole job, and it ate. 💅
