megasas_get_ctrl_info(9)

📦 version 7.3.1, in nixpkgs unstable

✨ megasas_get_ctrl_info ✨

okay so bestie, you know how every kernel driver has that one function that's like, the main character of getting the controller's whole vibe? yeah, that's this one. this is the megasas_get_ctrl_info(9) manual page, and it's lowkey iconic. 💅

🌸 SYNOPSIS 🌸

int megasas_get_ctrl_info (struct megasas_instance *instance );

🎀 ARGUMENTS 🎀

  • instance — the adapter soft state. that's it. that's the whole argument. it's giving "one job and she did it" energy. 💖

🦋 DESCRIPTION 🦋

so here's the tea, bestie: this function issues an internal command (that's a DCMD, for the uninitiated) to get the FW's controller structure. like, it literally goes to the firmware and is like "hey queen, can you hand over your controller struct?" and the FW is like "say less" and gives it up. 💁‍♀️

and why do we even care? because this info is mainly used to find out the maximum IO transfer per command supported by the FW. that's the whole point, no cap. it's the function you call when you need to know how much data you can yeet at the controller in a single command. periodt. 🔥

💜 SEE ALSO 💜

if you wanna go down the rabbit hole of every related function in this driver's extended universe, here's the whole fam (and yes, there are a lot of them — we stan a comprehensive link list):

so yeah, that's the whole page. this function is living in ./drivers/scsi/megaraid (that's the source, bestie) and it's dated October 2026. now go forth and get that controller info. you got this. 💖✨🫶
