💅 is_hint_crossing_range — Kernel API Manual ✨

okay so bestie, welcome to the is_hint_crossing_range(9) page 🫶 this is one of those kernel API manual pages (yes, the whole manual is literally called Kernel API Manual, we stay fancy) and it's honestly a little legend: it answers the question "hey, is this hint address wandering into reserved territory?" 👀

🌸 NAME 🌸

is_hint_crossing_range — check if hint address crossing specified reserved.

like, the whole vibe check of the function: does the hint address cross into the reserved range or not 💀

✨ SYNOPSIS ✨

bool is_hint_crossing_range (enum hl_va_range_type range_type , u64
start_addr , u32 size , struct asic_fixed_properties *prop );

it returns a bool, bestie — yes-or-no, no in-between, no "it's complicated" 🎀

🦋 ARGUMENTS 🦋

• range_type — the virtual space range type. like, which flavour of range are we even talking about 💅
• start_addr — the start virtual address. the place we start looking, our main character address ✨
• size — the block size. how much of a chunk we're dealing with 🍓
• prop — the asic properties structure, and that's the one we pull the reserved ranges from 👑

ngl, prop is doing all the heavy lifting here — no props, no reserved ranges, no answer. respect the struct 🙈
