drm_debugfs_gpuva_info(9)

✨ drm_debugfs_gpuva_info ✨

okay so this is a page from the Kernel API Manual, bestie — it's drm_debugfs_gpuva_info(9) and it's literally the function that dumps out your DRM GPU VA space 💅

🌸 SYNOPSIS 🌸

int drm_debugfs_gpuva_info (struct seq_file *m , struct drm_gpuvm *gpuvm );

🎀 ARGUMENTS 🎀

• m — pointer to the seq_file to write into, that's the thing your output goes into ✨
• gpuvm — the drm_gpuvm representing the GPU VA space, like the actual main character here 👑

🦋 DESCRIPTION 🦋

So what does it do? It dumps the GPU VA mappings of a given DRM GPU VA manager. That's it, that's the vibe 🫶

And for each DRM GPU VA space, drivers should call this function from their drm_info_list's show callback. Like, that's the whole assignment, no cap 📝

🌈 RETURN 🌈

• 0 on success — slay, we ate 💖
• -ENODEV if the gpuvm is not initialized — like bestie it's not even ready yet 😭
