setup_areas(9)

🦋 bestie, meet setup_areas(9) 🦋

welcome to the Kernel API Manual page for setup_areas(9), where we're mapping the spu regions into the address space and being iconic about it 💅✨

🌸 NAME 🌸

setup_areas — maps the spu regions into the address space. that's the whole assignment, bestie 🫶

✨ SYNOPSIS ✨

int setup_areas (struct spu *spu );

🎀 ARGUMENTS 🎀

• spu — the page says -- undescribed --, and honestly? respect. no extra lore, no made-up details, just vibes and a parameter name 🙈

💖 DESCRIPTION 💖

okay so here's the tea, no cap: the current HV requires the spu shadow regs to be mapped with the PTE page protection bits set as read-only. that's the requirement. that's the whole description. periodt 💀✨

🔥 RETURN 🔥

0 on success, or -errno on error. zero is the slay outcome; negative errno is the "welp" outcome 😭
