_base_build_zero_len_sge(9)

📦 version 7.3.1, in nixpkgs unstable

💅 _base_build_zero_len_sge(9) — like, the Kernel API Manual, but make it make sense 🎀

okay bestie, sit down, grab a strawberry drink 🍓, because we're talking about a tiny little kernel function from the Kernel API Manual and honestly? she's lowkey a hero.

✨ NAME ✨

_base_build_zero_len_sge — literally just here to build zero length sg entry 🫶

🌸 SYNOPSIS 🌸

void _base_build_zero_len_sge (struct MPT3SAS_ADAPTER *ioc , void *paddr
);

that's it. that's the whole vibe check. no return value, no drama, just vibes and two arguments 💅

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object, aka the main character of this whole situation 👑
  • paddr — virtual address for SGE, like the lil address she's gonna write into ✨

💖 DESCRIPTION 💖

okay so here's the tea ☕: this function creates a zero length scatter gather entry.

and why, you ask? because we need to insure the IOCs hardware has something to use if the target device goes totally brain dead 😭 and then tries to send data — even when none is asked for. like girl, nobody asked!! 🙈 but the hardware needs a lil something to hold onto anyway, so we give it this empty SGE and everybody stays calm. iconic defensive programming behavior, ngl 🔥

okay that's the whole thing bestie, go forth and build your zero length sge 🌈✨
