Description

MMIO base default is 56TB. User should not change the default value unless addressing a known issue. When set to 12TB, the system will map MMIO base to 12TB. Enable this feature for an OS that requires 44bit PCIe addressing. When set to 512GB, the system will map MMIO base to 512GB, and reduce the maximum support for memory to less than 512GB. Enable this option only for the 4 GPU DGMA issue.
