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.
