mpi3mr_map_smp_buffer(9)

🦋 mpi3mr_map_smp_buffer(9) 🦋

okay so bestie, this page is from the Kernel API Manual — I’m folding that manual-name detail right in here at the top, no copied header line, we’re keeping it cute. 🫶

💖 NAME 💖

mpi3mr_map_smp_buffer — map BSG dma buffer ✨

✨ SYNOPSIS ✨

int mpi3mr_map_smp_buffer (struct device *dev , struct bsg_buffer *buf ,
dma_addr_t *dma_addr , size_t *dma_len , void **p );

🎀 ARGUMENTS 🎀

• dev — Generic device reference — the device-y starting point, bestie.
• buf — BSG buffer pointer — points at the BSG buffer in question.
• dma_addr — Physical address holder — the holder for the physical address.
• dma_len — Mapped DMA buffer length. — the length of the mapped DMA buffer. Keep that period, it’s canon.
• p — Virtual address holder — the holder for the virtual address.

🌸 DESCRIPTION 🌸

This function maps the DMAable buffer. That’s the whole assignment. It’s giving one job, done with main character energy — no extra lore needed. 💅

🔥 RETURN 🔥

0 on success, non-zero on failure. So zero is the success slay, and non-zero means it didn’t go off. Periodt. 💖
