nvec_event_mask(9)

💅 nvec_event_mask(9) — Kernel API Manual ✨

🎀 NAME 🎀

okay so nvec_event_mask — fill the command string with event bitfield. literally the whole point, bestie, and it’s serving exactly what it says. 💖

✨ SYNOPSIS ✨

the signature is void and it’s giving “short but iconic.” copy it exactly, no editing:

void nvec_event_mask (char *ev , u32 mask );

🦋 ARGUMENTS 🦋

two args, and yes they both matter:

• ev — points to event command string
• mask — bit to insert into the event mask

🌸 DESCRIPTION 🌸

okay so Configure event command expects a 32 bit bitfield that describes which events to enable. no cap, that’s the vibe.

the bitfield has the following structure (from highest byte to lowest):

• system state bits 7-0
• system state bits 15-8
• oem system state bits 7-0
• oem system state bits 15-8

periodt — those four lines are the whole structure, and yes, highest byte to lowest is the order. 🫶
