amdgpu_vm_sdma_copy_ptes(9)

💖 NAME 💖

amdgpu_vm_sdma_copy_ptes — copy the PTEs from mapping. That's the whole name section, bestie, and it's already giving main character energy ✨. This page is from the Kernel API Manual, section 9, so you know exactly what kind of kernel-API situation we're in 🫶.

✨ SYNOPSIS ✨

Okay so here's the exact signature, no cap:

       void amdgpu_vm_sdma_copy_ptes (struct amdgpu_vm_update_params *p ,
       struct amdgpu_bo *bo , uint64_t pe , unsigned count );

🎀 ARGUMENTS 🎀

• p — see the amdgpu_vm_update_params definition. That's the whole lore for this one 💅.
• bo — the PD/PT to update. Slay, we're updating a page directory / page table, iykyk.
• pe — addr of the page entry. Literally the address of the page entry 🦋.
• count — number of page entries to copy. Yes bestie, we're copying count of them 🔥.

🦋 DESCRIPTION 🦋

So what does it do? It traces the parameters and calls the DMA function to copy the PTEs. That's it — that's the function. Iconic minimalism 🌈. It is not out here doing extra side quests in this description; the whole vibe is: trace the parameters, call the DMA function, copy the PTEs, periodt 💜.

🌈 SEE ALSO 🌈
