ShellPkg: Add varpolicy dynamic shell command and app Adds a new module (dynamic shell command) to ShellPkg that lists variable policy information for all UEFI variables on the system. Some other UEFI variable related functionality is also included to give a greater sense of platform UEFI variable state. This command is intended to help make variable policies more transparent and easier to understand and configure on a platform. Like all dynamic shell commands, a platform only needs to include `VariablePolicyDynamicCommand.inf` in their flash image to have the command registered in their UEFI shell. Include the following lines in platform DSC (in DXE components section): ``` ShellPkg/DynamicCommand/VariablePolicyDynamicCommand/VariablePolicyDynamicCommand.inf { <PcdsFixedAtBuild> gEfiShellPkgTokenSpaceGuid.PcdShellLibAutoInitialize|FALSE } ``` Include the following line in platform FDF: ``` INF ShellPkg/DynamicCommand/VariablePolicyDynamicCommand/VariablePolicyDynamicCommand.inf ``` A standalone UEFI application can also be built that uses the same underlying functional code as the dynamic shell command. The path to use in the DSC and FDF for the app: ``` ShellPkg/DynamicCommand/VariablePolicyDynamicCommand/VariablePolicyApp.inf ``` Cc: Zhichao Gao <zhichao.gao@intel.com> Cc: Michael D Kinney <michael.d.kinney@intel.com> Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Zhichao Gao <zhichao.gao@intel.com> Message-Id: <20231030203112.736-3-mikuback@linux.microsoft.com>
