kgdb_call_nmi_hook(9)

💖 NAME 💖

okay so bestie, welcome to kgdb_call_nmi_hook(9) from the Kernel API Manual — it's literally about calling kgdb_nmicallback() on the current CPU. periodt. 🎀

✨ SYNOPSIS ✨

void kgdb_call_nmi_hook (void *ignored );

🫶 ARGUMENTS 🫶

• ignored — bestie, this parameter is only here to match the prototype. it's giving "I'm just vibing in the signature" energy. 💅

🌸 DESCRIPTION 🌸

so here's the tea: if you're using the default implementation of kgdb_roundup_cpus, this function will be called per CPU. no cap.

and if you don't implement kgdb_call_nmi_hook, a default will be used. literally that simple. 🦋
