irq_matrix_assign(9)

💖 NAME 💖

okay bestie, this is irq_matrix_assign from the Kernel API Manual, section 9 ✨ lowkey a short page, highkey important: it's giving Assign a preallocated interrupt in the local CPU map 💅

🌸 SYNOPSIS 🌸

void irq_matrix_assign (struct irq_matrix *m , unsigned int bit );

no cap, that's the signature — return type void, args m and bit, fr fr.

🎀 ARGUMENTS 🎀

quick vibe check on the args:

• m — Matrix pointer 🫶 the matrix situation you're passing in.
• bit — Which bit to mark 💅 literally the bit.

✨ DESCRIPTION ✨

okay so the tea is short and iconic: This should only be used to mark preallocated vectors 👑 the preallocated vectors are the main character energy here, periodt.

⚠️ bestie, that "only" is not decorative. This should only be used to mark preallocated vectors — don't try to make it do extra side quests, okay? 💖
