amdgpu_vm_update_range(9)

🎀 NAME 🎀

amdgpu_vm_update_range — bestie, we're updating a range in the vm page table 💅✨

(also, hi, this is a page from the Kernel API Manual, so grab a snack 🍓)

---

🦋 SYNOPSIS 🦋

int amdgpu_vm_update_range (struct amdgpu_device *adev , struct
amdgpu_vm *vm , bool immediate , bool unlocked , bool flush_tlb , bool
allow_override , struct amdgpu_sync *sync , uint64_t start , uint64_t
last , uint64_t flags , uint64_t offset , uint64_t vram_base , struct
ttm_resource *res , dma_addr_t *pages_addr , struct dma_fence **fence );

---

✨ ARGUMENTS ✨

okay so here's the whole cast, no skips, everyone gets their moment 👑

• adev — the amdgpu_device pointer you're using for commands. main character energy, everything routes through it 🫶
• vm — the VM whose range we're updating. the star of the show, literally what we're editing 🌈
• immediate — immediate submission in a page fault. like, right now right now ⚡
• unlocked — unlocked invalidation during MM callback. living dangerously (it's fine, it's by design) 🙈
• flush_tlb — trigger tlb invalidation once the update has completed. the cleanup era 💅
• allow_override — change MTYPE for local NUMA nodes. yes, you're allowed to override, go off 👑
• sync — the fences we need to sync to. gotta wait for your friends before you leave 🧚
• start — start of the mapped range. where the story begins ⭐
• last — last mapped entry. where it ends, periodt 🔥
• flags — flags for the entries. the little details that matter, iykyk 💜
• offset — offset into nodes and pages_addr. don't forget this one, bestie 😭
• vram_base — base for vram mappings. the foundation of it all 🎀
• res — ttm_resource to map. the actual thing getting mapped, iconic 🌸
• pages_addr — DMA addresses to use for mapping. the addresses, slay 💀
• fence — optional resulting fence. optional!! no pressure 💖

---

💫 DESCRIPTION 💫

Fill in the page table entries between start and last. That's it. That's the vibe — you're filling in entries across that range, no cap 💅✨

---

🌟 RETURN 🌟

0 for success, negative erro code for failure. so like, zero = you ate, negative = something went sideways 😭

🔥 SEE ALSO 🔥

this list is long, bestie, but every single one of them is here because we don't do half-finished over here 💖
