Description
A VFIO-focused Linux kernel helps advanced users test hardware passthrough setups that need ACS override and i915 VGA arbiter patches. It is mainly relevant for virtualization, GPU passthrough, and lab systems that require these kernel changes.
This is a high-impact system component. Incorrect passthrough or kernel configuration can affect boot, graphics output, storage access, and device isolation, so keep a fallback kernel and understand the security tradeoffs of ACS override before relying on it.
