This driver implements a firmware volume block protocol instance which is stored in system memory. The MdeModulePkg/Universal/Variable/RuntimeDxe and MdeModulePkg/Universal/FaultTolerantWriteDxe drivers make use of this FVB instance to provide variable services. This driver links to a PlatformFvb library to allow for platform specific processing to take place when data is written to the FVB. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9315 6f19259b-4bc3-4df7-8a09-765794883524 |

=== OVMF OVERVIEW === The Open Virtual Machine Firmware (OVMF) project aims to support firmware for Virtual Machines using the edk2 code base. More information can be found at: https://edk2.tianocore.org/OVMF.html === STATUS === Current status: Alpha Current capabilities: * IA32 and X64 architectures * QEMU (0.9.1 or later) - Video, keyboard, IDE, CD-ROM, serial - Runs UEFI shell * UEFI Linux has booted (but is not stable) === FUTURE PLANS === * Stabilize UEFI Linux boot * Test/Stabilize UEFI Self-Certification Tests (SCT) results === BUILDING OVMF === Pre-requisites: * Build environment capable of build the edk2 MdeModulePkg. * A properly configured ASL compiler * Intel ASL compiler: Available from http://www.acpica.org or * Microsoft ASL compiler: Available from http://www.acpi.info Update Conf/target.txt ACTIVE_PLATFORM for OVMF: PEI arch DXE arch UEFI interfaces * OvmfPkg/OvmfPkgIa32.dsc IA32 IA32 IA32 * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 X64 * OvmfPkg/OvmfPkgX64.dsc X64 X64 X64 Update Conf/target.txt TARGET_ARCH based on the .dsc file: TARGET_ARCH * OvmfPkg/OvmfPkgIa32.dsc IA32 * OvmfPkg/OvmfPkgIa32X64.dsc IA32 X64 * OvmfPkg/OvmfPkgX64.dsc X64 Following the edk2 build process, you will find the OVMF binaries under the $WORKSPACE/Build/*/*/FV directory. The actual path will depend on how your build is configured. You can expect to find these binary outputs: * OVMF.fd * CirrusLogic5446.rom More information on building OVMF can be found at: * https://edk2.tianocore.org/build-ovmf.html === RUNNING OVMF on QEMU === * QEMU 0.9.1 or later is required. * Either copy, rename or symlink OVMF.fd => bios.bin * Either copy, rename or symlink CirrusLogic5446.rom => vgabios-cirrus.bin * Be sure to use qemu-system-x86_64, if you are using and X64 firmware. (qemu-system-x86_64 works for the IA32 firmware as well, of course.) * Use the QEMU -L parameter to specify the directory where the bios.bin and vgabios-cirrus.bin files are located. * Optionally you can use the QEMU -serial command to capture the OVMF debug messages. For example: -serial file:serial.log * The EFI shell is built into OVMF builds at this time, so it should run automatically if a UEFI boot application is not found on the removable media.
