ArmVirtPkg: Add kvmtool platform driver Kvmtool is a virtual machine manager that enables hosting KVM guests. It essentially provides a virtual hardware platform for guest operating systems. Kvmtool hands of a device tree containing the current hardware configuration to the firmware. A standards-based operating system would use ACPI to consume the platform hardware information, while some operating systems may prefer to use Device Tree. The KvmtoolPlatformDxe performs the platform actions like determining if the firmware should expose ACPI or the Device Tree based hardware description to the operating system.

ArmVirtPkg: Dispatch variable service if variable emulation is enabled The VariableRuntimeDxe links with NvVarStoreFormattedLib which is required to establish the dependency on OvmfPkg\VirtNorFlashDxe. The VirtNorFlashDxe installs the gEdkiiNvVarStoreFormattedGuid to indicate it has finished initialising the flash variable storage and that the variable service can be dispatched. However, the kvmtool guest firmware dynamically detects if CFI flash is absent and sets PcdEmuVariableNvModeEnable to TRUE indicating emulated runtime variable must be used. Therefore, in this scenario install the gEdkiiNvVarStoreFormattedGuid so that the variable service can be dispatched. Also link the NorFlashKvmtoolLib as a NULL library so that it can discover if the CFI flash is absent and setup the PCD PcdEmuVariableNvModeEnable. This is required in case the NorFlashDxe is not yet dispatched. Signed-off-by: Sami Mujawar <sami.mujawar@arm.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org>
