ipi_mux_create(9)

✨ NAME ✨

ipi_mux_create — Create virtual IPIs multiplexed on top of a single parent IPI. That’s the whole vibe, bestie 💖

🌸 SYNOPSIS 🌸

int ipi_mux_create (unsigned int nr_ipi , void (*mux_send)(unsigned int cpu) );

🎀 ARGUMENTS 🎀

• nr_ipi — number of virtual IPIs to create. This should be <= BITS_PER_TYPE(int), okay? Respect the limit, queen 👑
• mux_send — callback to trigger parent IPI for a particular CPU. It’s giving “you have one job” energy and we love that for it 🫶

🦋 DESCRIPTION 🦋

Returns first virq of the newly created virtual IPIs upon success or <=0 upon failure. So yeah — success hands you the first virq, failure gives you <=0. Simple, iconic, no notes 💅
