2011-01-30OvmfPkg: Add SerializeVariablesLib library classjljusten
This library provides an interface for converting the system variables into a binary and also restoring the system variables from that binary. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11284 6f19259b-4bc3-4df7-8a09-765794883524
2011-01-09OvmfPkg EMU FVB: Add 2 functions to PlatformFvbLibjljusten
Add PlatformFvbDataRead and PlatformFvbBlocksErased functions. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11241 6f19259b-4bc3-4df7-8a09-765794883524
2011-01-09OvmfPkg EMU FVB: Convert to FVB2 protocoljljusten
Convert from using EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL to EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11240 6f19259b-4bc3-4df7-8a09-765794883524
2011-01-09OvmfPkg PlatformFvbLib: Change PlatformFvbDataWrittenjljusten
The new parameters closely match the EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL Write function parameters. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11239 6f19259b-4bc3-4df7-8a09-765794883524

2010-03-21OVMF: Add Block MMIO protocol definitionjljusten
This protocol is similar to the standard UEFI BlockIo protocol, except it has no function calls and simply defines a base address in memory where reads & writes for the block device should occur. One planned usage is to fill a memory region with a small disk image, and allow it to be used as a normal disk by the standard drivers. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10295 6f19259b-4bc3-4df7-8a09-765794883524
2009-09-26OVMF: Add support for saving the NV variables to disk following each ↵jljusten
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
2009-09-26Add PlatformFvbLib to allow platform customization of an FVB driver.jljusten
git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9313 6f19259b-4bc3-4df7-8a09-765794883524
2009-09-16Implement NvVarsFileLib to save and restore non-volatile variables using a file.jljusten
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
