imr_write(9)

🎀 imr_write(9) 🎀

okay so welcome to the imr_write(9) page from the Kernel API Manual, bestie — it's giving kernel-internals main character energy, and we're gonna get through it together. 💅✨

💖 NAME 💖

imr_write — write an IMR at a given index. 🫶

🌸 SYNOPSIS 🌸

int imr_write (struct imr_device *idev , u32 imr_id , struct imr_regs *imr );

🦋 ARGUMENTS 🦋

• idev — pointer to imr_device structure. 💖
• imr_id — IMR entry to write. ✨
• imr — IMR structure representing address and access masks. 🎀

✨ DESCRIPTION ✨

Requires caller to hold imr mutex. 🔒 no cap, you gotta bring the lock.

Note lock bits need to be written independently of address bits. 🧚 lowkey important, so don't smoosh them together.

💅 RETURN 💅

0 on success or error code passed from mbi_iosf on failure. 😭
