68 platform are independently accessible, and not captive of the
69 other resources.
70 · Memory Mode: DCPMMs act as system memory under the control of
72 the operating system. In Memory Mode, any DDR in the platform
73 will act as a cache working in conjunction with the DCPMMs.

85 the operating system. In Memory Mode, any DDR in the platform
86 will act as a cache working in conjunction with the DCPMMs.
87 · Unknown: The current volatile mode cannot be determined.
89 AllowedAppDirectMode
91 (Default) The App Direct mode allowed as determined by BIOS setup.

107 platform are independently accessible, and not captive of the
108 other resources.
109 · Memory Mode: DCPMMs act as system memory under the control of
111 the operating system. In Memory Mode, any DDR in the platform
112 will act as a cache working in conjunction with the DCPMMs.
113 · App Direct: DCPMMs and DDR act as independent memory resources
115 under direct load/store control of the application.
