SYNOPSIS

           ipmctl show [OPTIONS] -system -capabilities

DESCRIPTION

       Shows the capabilities of the current platform as determined by platform firmware (BIOS)
       and this application.

OPTIONS

       -a, -all
           Shows all attributes.

           Note
           The all and display options are exclusive and may not be used together.

       -d (attributes), -display (attributes)
           Filters the returned attributes by explicitly specifying a comma separated list of any
           of the attributes defined in the Return Data section.

           Note
           The all and display options are exclusive and may not be used together.

       -h, -help
           Displays help for the command.

       -ddrt
           Used to specify DDRT as the desired transport protocol for the current invocation of
           ipmctl.

       -smbus
           Used to specify SMBUS as the desired transport protocol for the current invocation of
           ipmctl.

           Note
           The -ddrt and -smbus options are mutually exclusive and may not be used together.

       -o (text|nvmxml), -output (text|nvmxml)
           Changes the output format. One of: "text" (default) or "nvmxml".

       -u (B|MB|MiB|GB|GiB|TB| TiB), -units (B|MB|MiB|GB|GiB|TB| TiB)
           Changes the units that capacities are displayed in for this command. One of: bytes
           (B), megabytes (MB), mebibytes (MiB), gigabytes (GB), gibibytes (GiB), terabytes (TB)
           or tebibytes (TiB).

RETURN DATA

       The default behavior is to return the default attributes listed below; the options can be
       used to expand or restrict the output.

       PlatformConfigSupported
           (Default) Whether the platform level configuration of PMem 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
           (Default) Capacity alignment requirement for all memory types as reported by the BIOS.

       AllowedVolatileMode
           (Default) The volatile mode allowed as determined by BIOS setup. One of:

           •   1LM: One-level volatile mode. All configured PMem module resources on the platform
               assigned for memory usage are not in use.

           •   2LM: Two-level volatile mode/Memory Mode. PMem module resources configured as
               memory act as system memory. Any DDR on the platform will act as a cache working
               in conjunction with the PMem modules.

           •   Unknown: The allowed volatile mode cannot be determined.

       CurrentVolatileMode
           (Default) The current volatile mode. One of:

           •   1LM: One-level volatile mode. All configured PMem module resources on the platform
               assigned for memory usage are not in use.

           •   2LM: Two-level volatile mode/Memory Mode. PMem module resources configured as
               memory act as system memory. Any DDR on the platform will act as a cache working
               in conjunction with the PMem modules.

           •   Unknown: The current volatile mode cannot be determined.

       AllowedAppDirectMode
           (Default) 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.

       ModesSupported
           A list of PMem module modes supported by the BIOS. Refer to the command [Show Dimm] to

               assigned for memory usage are not in use.

           •   2LM: Two-level volatile mode/Memory Mode. PMem module resources configured as
               memory act as system memory. Any DDR on the platform will act as a cache working
               in conjunction with the PMem modules.

           •   App Direct: PMem module resources are under direct load/store control of the
               application. DDR is unaffected.
