💅 ilsel_enable_fixed(9) 💅

okay bestie, welcome to the Kernel API Manual page for ilsel_enable_fixed — yes, the whole manual name is folded in right here, no need to reread the header line. ✨ This one is short and iconic: it turns on an ILSEL set at a fixed interrupt level. Let’s get into it. 🎀

🌸 NAME 🌸

ilsel_enable_fixed — enable an ILSEL set at a fixed interrupt level. Slay. 💖

✨ SYNOPSIS ✨

int ilsel_enable_fixed (ilsel_source_t set , unsigned int level );

🦋 ARGUMENTS 🦋

• set — the ILSEL source. Peep the ilsel_source_t enum in include/asm-sh/ilsel.h. 👀
• level — the interrupt level, and it’s 1 - 15. Not 0, not 16, bestie. 🫶

💜 DESCRIPTION 💜

This enables a given ILSEL source at a fixed interrupt level. It’s necessary both for level reservation and for aliased sources that only exist on special ILSEL#s. No cap. 🔥

It returns an IRQ number (as ilsel_enable). 💅
