mpi3mr_refresh_trigger(9)

🌸 NAME 🌸

mpi3mr_refresh_trigger — Handler for Refresh trigger BSG.

Bestie, welcome to mpi3mr_refresh_trigger(9) from the Kernel API Manual. This is the page for the refresh trigger BSG handler, and yes it’s giving very niche kernel-core energy. 💅

✨ SYNOPSIS ✨

int mpi3mr_refresh_trigger (struct mpi3mr_ioc *mrioc , u8 page_action );

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. Like, the adapter’s main-character passport, fr.
• page_action — Page action. That’s the page action, no cap.

🦋 DESCRIPTION 🦋

Okay so here’s the tea: this function caches the driver page 2 in the driver’s memory by reading driver page 2 from the controller for a given page type, and it updates the HDB trigger values. Literally that’s the whole glow-up: read the page, cache it, refresh those HDB trigger values. 🫶

⭐ RETURN ⭐

0 on success and proper error codes on failure. So yeah, success is the 0 slay, and failure gives you proper error codes — iconic behavior. 😭
