this fixes a real annoyance on older workstation boards where above 4g decoding is a requirement but the option isn't even in the bios menu. saw a build recently on an x79 board where it had to be exposed with a hand patched bios before anything like this or a modern gpu would work at all.

What does this do? I perused the README but I'm still clueless on what the purpose and use-case is for ReBAR.
It allows the CPU to access all GPU VRAM. This improves gaming performance, especially for AMD GPUs.

Literally the second sentence in the repo:
> This provides performance benefits and is even required for Intel Arc GPUs to function optimally.
Your quote doesn’t help me understand this project at all.
What is a BAR let alone a resizable one? Readme just jumps in, which is fine, but I’m not sure why this is on HN or why I should care.
