💅 cik_sdma_vm_write_pages(9) ✨

okay so bestie, listen — we're deep in the cik_sdma zone of the Kernel API Manual, and this one is literally about updating PTEs by writing them manually. no cap, that's the whole vibe. it's cik_sdma_vm_write_pages, and she's serving "I fill an indirect buffer with commands so you don't have to" energy. 🎀

🌸 SYNOPSIS 🌸

void cik_sdma_vm_write_pages (struct radeon_device *rdev , struct
       radeon_ib *ib , uint64_t pe , uint64_t addr , unsigned count , uint32_t
       incr , uint32_t flags );

like, that's the whole signature, copy-pasted exactly, no editing, we respect her. 🫶

✨ ARGUMENTS ✨

  • rdev — the radeon_device pointer. yes queen, your device handle. 👑
  • ib — the indirect buffer we're gonna fill with commands. she's the canvas, we're the artist. 🎨
  • pe — addr of the page entry. that's the spot. 📍
  • addr — the dst addr to write into pe. where the data's actually going. 💌
  • count — number of page entries to update. do the math, bestie. 🔢
  • incr — increase next addr by incr bytes. we're striding, not strolling. 🚶‍♀️
  • flags — access flags. the permission slip, iykyk. 💅

🦋 DESCRIPTION 🦋

Update PTEs by writing them manually using sDMA (CIK). that's it, that's the whole description. she's concise, she's iconic, she didn't need to over-explain. ✨

ngl this is the "do it by hand" route — manual PTE writes via sDMA on CIK. no shortcuts, just vibes and commands. 🧚
