qcomtee_mem_object_map(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… qcomtee_mem_object_map β€” Kernel API Manual (9)

okay so bestie, listen up πŸ’– this one is literally the qcomtee_mem_object_map page from the Kernel API Manual, section 9, and it's giving "short but iconic". It does exactly one thing and it does it slayfully: it maps a memory object. That's the whole vibe. No cap. ✨


🌸 NAME 🌸

qcomtee_mem_object_map β€” map a memory object. that's it, that's the whole name section πŸŽ€


✨ SYNOPSIS ✨

int qcomtee_mem_object_map (struct qcomtee_object *object , struct
qcomtee_object **map_object , u64 *mem_paddr , u64 *mem_size , u32
*perms );

look at her πŸ‘‘ five params, one int return, zero drama. copy it exactly bestie, don't be out here retyping it from memory 😭


πŸ¦‹ ARGUMENTS πŸ¦‹

  • object β€” the memory object. the main character of this whole operation tbh 🫢
  • map_object β€” the mapping object that gets created. so you pass in a pointer-to-pointer and it hands you back the new one, periodt ✨
  • mem_paddr β€” the physical address of the memory. yes, physical, not virtual, don't come for me πŸ™ˆ
  • mem_size β€” the size of the memory. how big is the vibe? this tells you πŸ’…
  • perms β€” the QTEE access permissions. it's a u32 *, and it's literally the permission slip for this memory, iykyk πŸ”₯

πŸŽ€ RETURN πŸŽ€

on success it returns 0 πŸ’– and on failure it returns <0 😭 (that's how you know something went sideways, bestie β€” negative numbers are never the move).

so to recap: 0 = slay, <0 = not slay. keep that in your notes app fr fr πŸ“
