πŸ’… NAME πŸ’…

amdgpu_vm_cpu_update β€” bestie, it's the helper that updates page tables via CPU ✨

So like, this little cutie is out here doing page-table updates the CPU way, no cap.


🌸 SYNOPSIS 🌸

int amdgpu_vm_cpu_update (struct amdgpu_vm_update_params *p , struct
amdgpu_bo_vm *vmbo , uint64_t pe , uint64_t addr , unsigned count ,
uint32_t incr , uint64_t flags );

πŸŽ€ ARGUMENTS πŸŽ€

  • p β€” okay so this one's just vibes-adjacent, you go see the amdgpu_vm_update_params definition for the deets 🫢
  • vmbo β€” the PD/PT we're updating, like the actual main character of this whole operation
  • pe β€” byte offset of the PDE/PTE, relative to the start of PDB/PTB, iykyk
  • addr β€” the dst addr that gets written into pe, slay πŸ’–
  • count β€” how many page entries we're updating (yes it matters, don't sleep on it)
  • incr β€” increases the next addr by incr bytes, periodt
  • flags β€” hw access flags, iconic as always πŸ‘‘

✨ DESCRIPTION ✨

Write count number of PT/PD entries directly. That's it, that's the whole vibe β€” literally just straight-up writing them, no middleman energy πŸ¦‹
