💅 sdca_irq_enable_early(9) — aka the Kernel API Manual page you're about to devour

okay so bestie, we're in Kernel API Manual territory and this page is literally called sdca_irq_enable_early. yes it's a mouthful. no we're not skipping it. it's giving "small function, big bootstrap energy" and honestly? iconic. 🎀

✨ NAME ✨

sdca_irq_enable_early — re-enable the early SDCA IRQs for a given function. that's the whole vibe. early bird gets the interrupt. 🐦💜

🌸 SYNOPSIS 🌸

void sdca_irq_enable_early (struct sdca_function_data *function , struct
sdca_interrupt_info *info );

look at that signature. void return, so nothing comes back at you — it just does the thing. no cap. ✨

🦋 ARGUMENTS 🦋

  • function — a pointer to the SDCA Function. like, the actual function we're bootstrapping here. point at it. respectfully. 🫶
  • info — a pointer to the SDCA interrupt info for this device. it's the interrupt lore for your device specifically. keep it close. 💖

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this is the early version of the IRQ enable. the way that it works is it lets you enable IRQs that might be necessary to bootstrap functionality for other IRQs, like the FDL process. yes, IRQs enabling IRQs. it's giving main character energy, it's giving "you can't sit with us until you've got your own IRQ sorted". 😭

literally: some IRQs can't do their job until these early ones are already up and running. so we enable them first. periodt. 👑

ngl this is a "first in the door" kind of function — get the early ones slaying so the rest of the functionality can actually happen. 💅
