💅 hl_mmu_get_hop_pte_phys_addr — NAME

okay so bestie, welcome to the Kernel API Manual ✨ this one's called hl_mmu_get_hop_pte_phys_addr, and it's literally the function that extracts the PTE address from a HOP 🎀 iykyk

🌸 SYNOPSIS

u64 hl_mmu_get_hop_pte_phys_addr (struct hl_ctx *ctx , struct
hl_mmu_properties *mmu_prop , u8 hop_idx , u64 hop_addr , u64 virt_addr
);

she takes five args and returns a u64, no cap 💖

🦋 ARGUMENTS

  • ctx — pointer to the context structure to initialize 🫶
  • mmu_prop — the MMU properties, mmkay?
  • hop_idx — the HOP index, like which hop we're on 💅
  • hop_addr — the HOP address itself
  • virt_addr — the virtual address you're translating for, that's the whole vibe ✨

👑 DESCRIPTION

she returns the matching PTE value on success 💖 otherwise you get U64_MAX 😭 (that's the "nope" value, so watch for it)
