💖 ilsel_enable(9) — Enable an ILSEL set 💖

Hii bestie! Welcome to the Kernel API Manual page for ilsel_enable(9) — it's giving “turn on an ILSEL set” and we're obsessed. 🎀

---

✨ NAME ✨

ilsel_enable — Enable an ILSEL set. 💅

---

🦋 SYNOPSIS 🦋

int ilsel_enable (ilsel_source_t set );

---

🌸 ARGUMENTS 🌸

• set — the ILSEL source, bestie. It's the ilsel_source_t enum, so peep include/asm-sh/ilsel.h for the full lineup. 🌈

---

🔥 DESCRIPTION 🔥

Okay so here's the tea: ilsel_enable enables a given non-aliased ILSEL source (<= ILSEL_KEY) at the highest available interrupt level. ✨

Callers should take care to order callsites, noting descending interrupt levels — like, keep that interrupt-level lineup in check, iykyk. 👑

Aliasing FPGA and external board IRQs need to use ilsel_enable_fixed. 🫶

The return value is an IRQ number that can later be taken down with ilsel_disable. No cap. 💯

That's the whole vibe check, bestie. This page comes from ./arch/sh/boards/mach-x3proto, dated October 2026, and it's all about ilsel_enable(9). Slay 💅✨
