From 50944545795641de735586d4803f8fc38b43874e Mon Sep 17 00:00:00 2001 From: jljusten Date: Wed, 16 Sep 2009 16:28:55 +0000 Subject: Implement NvVarsFileLib to save and restore non-volatile variables using a file. 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 --- OvmfPkg/Include/Library/NvVarsFileLib.h | 35 +++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 OvmfPkg/Include/Library/NvVarsFileLib.h (limited to 'OvmfPkg/Include/Library') diff --git a/OvmfPkg/Include/Library/NvVarsFileLib.h b/OvmfPkg/Include/Library/NvVarsFileLib.h new file mode 100644 index 0000000000..63b1642f54 --- /dev/null +++ b/OvmfPkg/Include/Library/NvVarsFileLib.h @@ -0,0 +1,35 @@ +/** @file + Provides functions to save and restore NV variables in a file. + + Copyright (c) 2009, Intel Corporation
