Return Data

  • PlatformConfigSupported: Whether the platform level configuration of persistent memory modules can be modified with the host software. One of:
    • 0: Changes must be made in the BIOS.
    • 1: The command Create Memory Allocation Goal is supported.
  • Alignment: Capacity alignment requirement for all memory types as reported by the BIOS.
  • AllowedVolatileMode: The volatile mode allowed as determined by BIOS setup. One of:
    • 1LM: One-level volatile mode. All memory resources in the platform are independently accessible, and not captive of the other resources.
    • Memory Mode: Modules act as system memory under the control of the operating system. In Memory Mode, any DDR in the platform will act as a cache working in conjunction with the persistent memory modules.
    • Unknown: The allowed volatile mode cannot be determined.
  • CurrentVolatileMode: The current volatile mode. One of:
    • 1LM: One-level volatile mode. All memory resources in the platform are independently accessible, and not captive of the other resources.
    • Memory Mode: Modules act as system memory under the control of the operating system. In Memory Mode, any DDR in the platform will act as a cache working in conjunction with the persistent memory modules.
    • Unknown: The current volatile mode cannot be determined.
  • AllowedAppDirectMode: The App Direct mode allowed as determined by BIOS setup. One of:
    • Disabled: App Direct support is currently disabled by the BIOS.
    • App Direct: App Direct support is currently enabled by the BIOS.
    • Unknown: The current App Direct support cannot be determined.
