okay so bestie, welcome to the sdma_v6_0_vm_write_pte(9) page — it's a Kernel API Manual moment, and honestly? iconic. this is the function that goes "fine, i'll write the PTEs myself" and honestly we respect the hustle 🫶

uint64_t value , unsigned count , uint32_t incr );

like… look at that signature. it's giving structured. it's giving typed. we stan 💖

🦋 ARGUMENTS 🦋

  • ib — the indirect buffer you're filling up with commands. think of it as the group chat where all the commands get dropped. 📥
  • pe — addr of the page entry. yes, the page entry. the main character of this whole operation 👑
  • value — the dst addr to write into pe. literally just the destination address going in there. slay. ✨
  • count — number of page entries to update. how many we doing? this many. 🔢
  • incr — increase next addr by incr bytes. so each subsequent entry steps forward by this much. baby steps, but make it bytes 🚶‍♀️

💜 DESCRIPTION 💜

Update PTEs by writing them manually using sDMA. that's it, that's the description. no fancy auto-magic, no "the hardware handles it" — we handle it, by hand, with sDMA. it's giving DIY energy and honestly? obsessed. 💅
