💖 amdgpu_vram_mgr_alloc_sgt(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is amdgpu_vram_mgr_alloc_sgt(9) and it's lowkey the moment where a chunk of your VRAM allocation gets its own little scatter-gather table. very main character of it. ✨

🌸 NAME 🌸

amdgpu_vram_mgr_alloc_sgt — allocate and fill a sg table, fr fr

🎀 SYNOPSIS 🎀

int amdgpu_vram_mgr_alloc_sgt (struct amdgpu_device *adev , struct
       ttm_resource *res , u64 offset , u64 length , struct device *dev , enum
       dma_data_direction dir , struct sg_table **sgt );

like… look at all those arguments. she's got range. 💅

🦋 ARGUMENTS 🦋

  • adev — the amdgpu device pointer 🫶
  • res — the TTM memory object (iykyk)
  • offset — byte offset from the base of VRAM BO 🔥
  • length — number of bytes to export in sg_table
  • dev — the other device 👀
  • dir — dma direction
  • sgt — the resulting sg table, the whole point of the whole thing 💀

⭐ DESCRIPTION ⭐

Allocate and fill a sg table from a VRAM allocation. that's it, that's the vibe — you hand it a VRAM allocation and it comes back with a filled-in scatter-gather table. iconic behavior honestly. 👑
