* OvmfPkg/NvVarsFileLib: Shortcut ConnectNvVarsToFileSystem in secure-bootMin M Xu2022-09-061-0/+7
| | | | | | | | | | | | | | | | | OvmfPkg/Library/NvVarsFileLib allows loading variables into emulated varstore from a on-disk NvVars file. We can't allow that when secure boot is active. So check secure-boot feature and shortcut the ConnectNvVarsToFileSystem() function when sb is enabled.

* OVMF: Add support for saving the NV variables to disk following each ↵jljusten2009-09-261-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | SetVariable call. Note: * This only works before ExitBootServices * For OVMF, variables are only preserved on the disk if there is a hard disk connected which has a writeable FAT file system. The Ovmf/Library/EmuVariableFvbLib library will look for the gUefiOvmfPkgTokenSpaceGuid.PcdEmuVariableEvent PCD to be set to a non-zero value. If set, it is treated as an event handle, and each write to the EmuVariableFvb will cause the event to be signaled. In this change, the OVMF platform BDS library sets up this event, and sets the PCD so that after each write to the EMU Variable FVB, the non-volatile variables will be saved out to the file system. The end result is that NV variables that are written prior to the ExitBootServices call should be preserved by storing them on the disk. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9318 6f19259b-4bc3-4df7-8a09-765794883524

* Implement NvVarsFileLib to save and restore non-volatile variables using a file.jljusten2009-09-165-0/+1101
This library provides an interface where variables can be saved and restored using a file in a file system accessible to the firmware. It is expected that a platform BDS library will use this library. The platform BDS implementation can decide which devices to connect and then to attempt to use for saving and restoring NV variables. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9272 6f19259b-4bc3-4df7-8a09-765794883524
