okay so real talk, this is a page from the Kernel API Manual and it's honestly so niche but so important, bestie. buckle up 🎀

✨ NAME ✨

mem_info_vis_vram_total — the lil sysfs file that tells you how much visible VRAM your amdgpu device has rn 👑

---

🦋 DESCRIPTION 🦋

so the amdgpu driver ships a sysfs API, right? and its whole job is reporting the current total visible VRAM available on the device. iconic behaviour, no notes 💅

the file you wanna look at is called mem_info_vis_vram_total, and that's the one doing the work here — it returns the total amount of visible VRAM in bytes. bytes, bestie. not megabytes, not vibes. bytes. 📏✨

like literally, that's it. that's the whole function of the file. read it, get a number, know your total visible VRAM. slay 🫶
