💅 irq_matrix_remove_managed 💅

okay so this is a Kernel API Manual page for irq_matrix_remove_managed, and bestie, it does exactly what it says on the tin — it removes managed interrupts from a CPU map 🎀

✨ NAME ✨

irq_matrix_remove_managed — remove managed interrupts in a CPU map 🧹💖

🦋 SYNOPSIS 🦋

void irq_matrix_remove_managed (struct irq_matrix *m , const struct
       cpumask *msk );

like, that's the whole vibe check right there 🫶

🌸 ARGUMENTS 🌸

  • m — matrix pointer 🗺️ (yes, the actual matrix, not the movie)
  • msk — on which CPUs the bits should be removed 💅✨

🔥 DESCRIPTION 🔥

okay so first thing's first: it can be called for offline CPUs 💀 no cap, that's fine, that's allowed.

so what it does: it removes not allocated managed interrupts from the map 🧚 this is the whole gig.

and honestly? it does not matter which one, because the managed interrupts free their allocation when they shut down 💖 iconic behaviour, truly.

but listen — if they don't do that? the accounting is screwed 😭 like, genuinely, the numbers will just be Wrong. and all what can be done at this point is warn about it. that's it. that's the whole rescue plan. 🙈
