STRUCT HL_MMU_HOP_INFO(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for struct hl_mmu_hop_info(9) — and no cap, this struct is literally the structure that describes the TLB hops and their hop-entries that were created in order to translate a virtual address into a physical one. it's giving "translation journey scrapbook" 💅✨

✨ SYNOPSIS ✨

here's the struct in all its iconic glory, bestie — spelling is sacred, don't touch it:

struct hl_mmu_hop_info {
    u64 scrambled_vaddr;
    u64 unscrambled_paddr;
    struct hl_mmu_per_hop_info hop_info[MMU_ARCH_6_HOPS];
    u32 used_hops;
    enum hl_va_range_type range_type;
 };

🧸 Members 🧸

these are the fields, and yes every single one is a main character:

• scrambled_vaddr — the value of the virtual address after scrambling. this address replaces the original virtual-address when it's mapped in the MMU tables. iykyk 🌀
• unscrambled_paddr — the un-scrambled physical address. periodt.
• hop_info — array holding the per-hop information used for the translation. the whole hop squad 🐇
• used_hops — the number of hops used for the translation. count 'em, bestie 🔢
• range_type — virtual address range type. the vibe check on the range 🌈
