I just got a ThinkPad A485 that has a Radeon Vega 6 GPU (on Ryzen 3 PRO 2300U). This type of igpu gets VRAM from the system memory. And in the BIOS, you can allocate up the 1GB for it. But I believe these are supposed to be able to dynamically allocate memory if it needs to go over the 1GB ceiling with AMD HUMA? Well, even when running like 8 instances of vkmark at once (2560x1440), neither Ubuntu resource monitor, nor radeontop reports it going over ~850MB of VRAM usage. Am I wrong in thinking it dynamically allocates, or is it just not being reported anywhere? The Laptop isn't MEANT for gaming usage, so it's not a huge issue, but still.
Also, supposedly there is an older version of BIOS that allows me to allocate 2GB of RAM, but I'm not going to fuck with the BIOS on a new (used) laptop.
