bfa_nw_ioc_smem_read(9)

💅 bfa_nw_ioc_smem_read(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, you've got a Brocade NIC staring at you, and you need data out of SMEM. That's literally this function's whole job. Say hi to bfa_nw_ioc_smem_read — it reads data from SMEM into the host through the PCI memmap, and honestly? iconic behaviour. ✨

---

🌸 SYNOPSIS 🌸

int bfa_nw_ioc_smem_read (struct bfa_ioc *ioc , void *tbuf , u32 soff ,
       u32 sz );

four args, one int back, no drama. 🫶

---

🎀 ARGUMENTS 🎀

• ioc — memory for IOC. yeah that's the whole description, she's mysterious like that 💅
• tbuf — the app memory where the data from smem gets stored, i.e. your cute lil landing spot for the bytes 🦋
• soff — smem offset, aka where in smem we're starting from
• sz — size of smem in bytes, so like, how much we're grabbing

ngl bestie, that's the whole page. no options, no exit statuses, no environment variables — just four args, a return int, and a whole lot of flash-adjacent friends. not me being jealous of a function with this many mutuals 😭
