mega_get_max_sgl(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mega_get_max_sgl(9) — the kernel API manual, bestie edition 🎀

okay so real talk, this is a page from the Kernel API Manual, section 9. It's about one tiny lil function in the megaraid driver and honestly? she's got main character energy for something so small. let's get into it ✨

🌸 NAME 🌸

mega_get_max_sgl — and that's it. That's the whole description.

not me noticing the original page literally leaves the name description blank 😭 like the manpage author said "you'll figure it out" and dipped. no cap, there is nothing after the dash. we move.

✨ SYNOPSIS ✨

void mega_get_max_sgl (adapter_t *adapter );

that's the whole signature, bestie. she returns void — nothing comes back out, she just does her thing and leaves 💅

🦋 ARGUMENTS 🦋

  • adapter — pointer to our soft state 🫶 that's it, that's the one (1) argument. she takes exactly one pointer and she's happy.

💖 DESCRIPTION 💖

okay so here's the vibe: mega_get_max_sgl figures out the maximum number of scatter-gather elements that this version of the firmware supports 🔥

literally that's the job. firmware version goes in, max SGL count comes out (well — not out out, she's void, but you get the vibe). it's giving "let me check what this firmware can handle before we commit to anything" and honestly? iconic. she's doing reconnaissance for you so you don't have to 🙈

👑 SEE ALSO 👑

the friend group 🫶 — every single one of these is in the kernel file ./drivers/scsi/megaraid.c:

like, that's the whole group chat 💀 every proc_show_* sibling, every irq handler, every scb helper — all present and accounted for. no one left on read 🫶

🧚 sign-off 🧚

and that's the page, bestie!! this one came from ./drivers/scsi and it's dated October 2026 ⭐ slay, go read the manpage, ily, bye 💜🌈
