💖 _base_get_chain_phys (9) 💖

okay bestie, welcome to the Kernel API Manual page for _base_get_chain_phys(9) — yes, we are literally in the group chat of low-level scatter gather chain lore. No cap, this one is about figuring out a physical address in BAR0 for scatter gather chains, based on the smid you hand it. Let's go. 💅

✨ NAME ✨

_base_get_chain_phys — calculates and returns the physical address in BAR0 for scatter gather chains, for the provided smid. That's the whole vibe. 🫶

🦋 SYNOPSIS 🦋

phys_addr_t _base_get_chain_phys (struct MPT3SAS_ADAPTER *ioc , u16 smid
, u8 sge_chain_count );

it's giving function signature, periodt. ✨

🎀 ARGUMENTS 🎀

  • ioc — per adapter object. the main character adapter energy, honestly.
  • smid — system request message index. iconic little index, no notes.
  • sge_chain_count — Scatter gather chain count. the count of the scatter gather chain situation, bestie.

🔥 RETURN 🔥

Physical chain address. that's it, that's the return — a physical chain address, and we love that for it. 💖
