ENUM VMW_DMA_MAP_MODE(9)

💅 enum vmw_dma_map_mode(9) 💅

okay so this is a page from the Kernel API Manual bestie, and it's literally all about enum vmw_dma_map_mode — the icon of the show ✨

---

🌸 NAME 🌸

enum vmw_dma_map_mode — the little enum that tells you how to perform TTM page dma mappings 🎀

---

✨ SYNOPSIS ✨

enum vmw_dma_map_mode {
    vmw_dma_alloc_coherent ,
    vmw_dma_map_populate ,
    vmw_dma_map_bind

};

like. the vibes are immaculate, the syntax is minimal, we love to see it 💅

---

🦋 Constants 🦋

• vmw_dma_alloc_coherent — use TTM coherent pages, periodt ✨
• vmw_dma_map_populate — unmap from DMA just after unpopulate 🫶
• vmw_dma_map_bind — unmap from DMA just before unbind 👑

ngl that's the whole enum, it ate and left no crumbs 💖

iykyk 💀 the whole friend group is here, no one got left on read 🙈

lowkey a reminder: this is all kernel-space stuff, so treat it with the respect it deserves, bestie — no cap 🧚

okay that's the whole page, and here's your cute lil sign-off 🎀: this one lives in ./drivers/gpu/drm/vmwgfx, it's dated October 2026, and it goes by enum vmw_dma_map_mode(9) — slay, bye 💜🌈⭐
