🌸 NAME 🌸

sdma_v7_1_vm_set_pte_pde — update the page tables using sDMA

like, that's literally the whole personality. it updates page tables. using sDMA. no cap 💅

✨ SYNOPSIS ✨

void sdma_v7_1_vm_set_pte_pde (struct amdgpu_ib *ib , uint64_t pe ,
uint64_t addr , unsigned count , uint32_t incr , uint64_t flags );

void return, six arguments, zero notes. she's a void girlie — doesn't return a thing, just does the thing. 🫶

🎀 ARGUMENTS 🎀

  • ib — indirect buffer to fill with commands 🧚 this is where all the little command bytes get poured in
  • pe — addr of the page entry (yes the arg is called pe and it holds an addr, iykyk)
  • addr — the dst addr that gets written into pe 💖
  • count — how many page entries we're updating, like how many besties are coming to the party
  • incr — bump the next addr up by incr bytes each time, lil step-by-step walk 🌈
  • flags — access flags 👑

🦋 DESCRIPTION 🦋

Update the page tables using sDMA. that's it, that's the sentence, she said what she said and she ate 🔥
