🎀 _config_all...g_dma_memory(9) 🎀

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the big-kid kernel docs now, and honestly? this one's a lil cutie. it's a tiny helper function living its best life in the mpt3sas config code and it has one job. let's get into it 💅

🌸 NAME 🌸

_config_alloc_config_dma_memory — literally just obtain physical memory. that's it. that's the whole vibe. lowkey iconic for how straightforward it is ✨

🦋 SYNOPSIS 🦋

int _config_alloc_config_dma_memory (struct MPT3SAS_ADAPTER *ioc ,
struct config_request *mem );

it returns an int and takes two args, no cap. copy it exactly if you're typing it out, i'm not gonna let you fumble the signature 🙈

💖 ARGUMENTS 💖

  • ioc — the per adapter object. think of it as the main character of this whole driver situation 👑
  • mem — a struct config_request. this is the lil container that's gonna get the memory, she's the one receiving 🫶

⭐ DESCRIPTION ⭐

so basically: this function is a wrapper for obtaining dma-able memory for a config page request. that's it, that's the tweet.

it's giving "middle manager who exists so the other functions don't have to repeat themselves." not glamorous, but absolutely necessary. highkey a team player 💜

🔥 RETURN 🔥

  • returns 0 for success — slay 🎉
  • returns non-zero for failure — not slay, check your args 😭
