2015-01-14OvmfPkg: QemuBootOrderLib: expose QEMU's "-boot menu=on[,splash-time=N]"Laszlo Ersek
The QEMU command line option -boot menu=on is meant to have the guest firmware wait for a firmware-specific interval for the user to enter the boot menu. During the wait, the user can opt to enter the boot menu, or interrupt the wait and proceed to booting at once. If the wait interval elapses, the firmware should boot as it normally would. The QEMU command line option -boot menu=on,splash-time=N means the same, except the firmware should wait for cca. N milliseconds instead of a firmware-specific interval. We can approximate this behavior quite well for edk2's virtual platforms because the Intel BDS front page already supports a progress bar, with semantics similar to the above. Let's distill the fw_cfg bits underlying "-boot menu=on,splash-time=N" for the BDS policies, in the form of a timeout value they can pass to Intel's PlatformBdsEnterFrontPage(). If the boot menu is not requested, we return "gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPlatformBootTimeOut", which is what the virtual platforms use right now. If the boot menu is requested without specifying the timeout, we return the same PCD, unless it would cause us to skip the boot menu at once. In the latter case, we return 3 seconds (as an approximation of the 2500 ms SeaBIOS default.)

2015-01-02OvmfPkg: QemuBootOrderLib: OFW-to-UEFI translation for virtio-mmioLaszlo Ersek
The TranslateMmioOfwNodes() function recognizes the following OpenFirmware device paths: virtio-blk: /virtio-mmio@000000000a003c00/disk@0,0 virtio-scsi disk: /virtio-mmio@000000000a003a00/channel@0/disk@2,3 virtio-net NIC: /virtio-mmio@000000000a003e00/ethernet-phy@0 The new translation can be enabled with the "PcdQemuBootOrderMmioTranslation" Feature PCD. This PCD also controls if the "survival policy" covers unselected boot options that start with the virtio-mmio VenHw() node.

2015-01-02OvmfPkg: QemuBootOrderLib: widen ParseUnitAddressHexList() to UINT64Laszlo Ersek
The OpenFirmware device path nodes that QEMU generates for virtio-mmio transports contain 64-bit hexadecimal values (16 nibbles) -- the base addresses of the register blocks. In order to parse them soon, ParseUnitAddressHexList() must parse UINT64 values. Call sites need to be adapted, as expected.

2015-01-02OvmfPkg: QemuBootOrderLib: featurize PCI-like device path translationLaszlo Ersek
In preparation for adding OpenFirmware-to-UEFI translation for "MMIO-like" OFW device path fragments, let's turn the currently exclusive "PCI-like" translation into "just one" of the possible translations. - Rename TranslateOfwNodes() to TranslatePciOfwNodes(), because it is tightly coupled to "PCI-like" translations. - Rename REQUIRED_OFW_NODES to REQUIRED_PCI_OFW_NODES, because this macro is specific to TranslatePciOfwNodes(). - Introduce a new wrapper function under the original TranslateOfwNodes() name. This function is supposed to try translations in some order until a specific translation returns a status different from RETURN_UNSUPPORTED. - Introduce a new Feature PCD that controls whether PCI translation is attempted at all. - The boot option "survival policy" in BootOrderComplete() must take into account if the user was able to select PCI-like boot options. If the user had no such possibility (because the Feature PCD was off for PCI-like translation), then we ought to keep any such unselected boot options.
