Isn’t that setting just a historical thing annd ann integrated GPU is able to access any system memory that is mapped by the IOMMU? I assume this is how it works for people using the NVIDIA Jetson AGX Orin 64GB Developer Kit to do inference. I do not know why it would be different for AMD APUs.

I remember somebody complaining about it on reddit, unable to overcome some BIOS limitation on an AMD G processor. Even on M3 Max one had to issue a special command to enable GPU to access more memory.

The command on the M3 Max is a sysctl command to adjust an operating system enforced limit. That is different than the aperture setting in the bios. The limitation on AMD is more interesting and more relevant.
