add_opal_mem_range(9)

💖 NAME 💖

Okay bestie, welcome to add_opal_mem_range(9) from the Kernel API Manual — the function that adds an OPAL region to the given memory ranges list. It’s giving “small but iconic helper” energy. 🎀

✨ SYNOPSIS ✨

int add_opal_mem_range (struct crash_mem **mem_ranges );

🫶 ARGUMENTS 🫶

• mem_ranges — the range list you’re adding the memory range to. That’s the whole assignment, bestie. 💅

💅 DESCRIPTION 💅

The vibe check is simple: it returns 0 on success, and a negative errno on error. No cap. ✨
