xe_svm_alloc_vram(9)

🌸 NAME 🌸

okay so bestie, meet xe_svm_alloc_vram(9) — straight out of the Kernel API Manual — and it is literally the function that allocates device memory pages for a range, migrating existing data while it does it. slay. 💅✨

✨ SYNOPSIS ✨

the vibe check is this exact signature, no edits, periodt:

       int xe_svm_alloc_vram (struct xe_svm_range *range , const struct
       drm_gpusvm_ctx *ctx , struct drm_pagemap *dpagemap );

🎀 ARGUMENTS 🎀

• range — the SVM range. that's the zone we're working with, bestie. 🦋
• ctx — the DRM GPU SVM context. context is giving main character energy here. 💜
• dpagemap — the struct drm_pagemap representing the memory to allocate. literally the memory-map situation for the allocation. 🫶

💖 RETURN 💖

it returns 0 on success, or an error code on failure. that's it, that's the return vibe. no cap. 🌈
