6.9.1.1. AMD GPU Optimization Recommendations
To maximize performance and ensure compatibility, AMD recommends the following BIOS and system-level configurations:
Enable Large BAR Support
Required for peer-to-peer GPU memory access.
Enable SR-IOV (if applicable)
Useful for virtualized environments or shared GPU usage.
Disable Access Control Services (ACS)
ACS may route peer-to-peer transactions through the PCIe root complex, which can degrade performance.
