💅 amdgpu_gmc_set_pte_pde(9) 💅

okay so welcome to the Kernel API Manual page for amdgpu_gmc_set_pte_pde(9), bestie. We’re folding the manual name in right here near the top instead of copy-pasting the whole header line, because we’re cute AND efficient. This is the one that updates the page tables using the CPU — yes, the CPU is doing the little page-table glow-up. ✨

🌸 NAME 🌸

amdgpu_gmc_set_pte_pde — update the page tables using CPU 🫶

✨ SYNOPSIS ✨

Here’s the exact signature, bestie, so you can paste it with your whole chest:

int amdgpu_gmc_set_pte_pde (struct amdgpu_device *adev , void
*cpu_pt_addr , uint32_t gpu_page_idx , uint64_t addr , uint64_t flags );

🎀 ARGUMENTS 🎀

• adev — the amdgpu_device pointer. Your main character device struct 👑
• cpu_pt_addr — the CPU address of the page table. The CPU-side home address, iykyk 🏠
• gpu_page_idx — the entry in the page table to update. Yes, this specific entry, bestie 🎯
• addr — the dst addr to write into pte/pde. Literally the destination address going into the pte/pde 💌
• flags — the access flags. The permission-y accessory for the fit 💅

💖 DESCRIPTION 💖

okay so the whole mood is: update the page tables using CPU. That’s it, that’s the function. No cap. The CPU is doing the page-table update, and honestly? Slay ✨
