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.)

ArmVirtualizationPkg: Intel BDS: load EFI-stubbed Linux kernel from fw_cfg
A number of tools depend on passing the kernel image, the initial ramdisk,
and the kernel command line to the guest on the QEMU command line (options
-kernel, -initrd, -append, respectively). At the moment, these QEMU
options work, but the guest kernel loaded this way is launched by a
minimal binary firmware that is dynamically composed by QEMU. As a
consequence, such a kernel has no UEFI environment.
This patch enables -kernel, -initrd, -append to work on top of the
ArmVirtualizationQemu firmware build. The approach it takes is different
from how the same functionality is implemented in OvmfPkg.
OvmfPkg contains a full-fledged Linux boot loader (see
"OvmfPkg/Library/PlatformBdsLib/QemuKernel.c" and
"OvmfPkg/Library/LoadLinuxLib/"). OVMF's LoadLinuxLib sets up the required
kernel environment in a sophisticated way (including x86-specific
artifacts like the GDT), calls ExitBootServices() itself (for legacy
kernels without EFI handover protocol), and jumps to the kernel (using x86
assembly).
In ArmVirtualizationPkg's PlatformIntelBdsLib, we require the kernel being
loaded to have an EFI stub -- that is, to be a genuine UEFI application.
(The EFI stub is not an additional burden for guest kernels -- the EFI
stub is a hard requirement anyway because it needs to process the DTB
heavily:
- it removes memory nodes,
- it removes memreserve entries,
- it adds UEFI properties to the "chosen" node,
- it calculates and installs virt-to-phys mappings with
SetVirtualAddressMap() in a way that enables kexec [planned].
Kudos to Ard Biesheuvel for summarizing the above.)
An EFI-stubbed Linux guest kernel can be loaded with plain
gBS->LoadImage(). The EFI stub will look up its own
EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL instance (ie. the device path where
it has been loaded from), and it will locate the initial ramdisk named by
the "initrd" command line parameter as a *sibling file* on the same
device.
The initrd file is then loaded using the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.
This approach enables the EFI stub to load the initial ramdisk from normal
EFI System Partitions, from remote PXE/TFTP directories -- and it enables
us to provide the initrd from memory as well.
In this patch:
- We download the kernel image, the initrd image, and the kernel command
line, using QEMU's fw_cfg interface.
- We create a read-only EFI_SIMPLE_FILE_SYSTEM_PROTOCOL instance that has
just a root directory, with the three downloaded files in it.
- The handle that carries the simple file system has a single-node
VenHw(...) device path (not counting the terminator node).
- We load the EFI-stubbed kernel (which is a UEFI application) with
gBS->LoadImage(), passing "VenHw(...)/kernel" as device path. This
causes gBS->LoadImage() to call back into our filesystem.
- Appended to the downloaded command line, we pass "initrd=initrd" to the
EFI stub.
- Once the EFI stub is running, it loads the initial ramdisk from the
"sibling" device path "VenHw(...)/initrd", also calling back into our
filesystem.

ArmPlatformPkg/ArmVirtualizationPkg/VirtFdtDxe/VirtFdtDxe.inf) for

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.
In PlatformBdsPolicyBehavior() we should follow the same pattern as in
OvmfPkg's: after the consoles are connected,
- connect all drivers and devices,
- enumerate all boot options,
- enter the Intel BDS FrontPage if the user presses a key different from
Enter.

For ARM guests, S3 is in the distant future, but we can see several
shorter term applications for fw_cfg that all reside in DXE:
- controlling boot order (to be implemented in PlatformBdsLib for Intel
BDS),
- supporting -kernel / -initrd / -append boot on QEMU (to be implemented
in PlatformBdsLib for Intel BDS, similarly),
- loading and linking ACPI tables,
- installing SMBIOS tables.
Therefore it makes sense to add a simple MMIO-based fw_cfg client library
to ArmVirtualizationPkg that for the moment is only available to
DXE_DRIVER modules.
Because MMIO accesses are costly on KVM/ARM, InternalQemuFwCfgReadBytes()
accesses the fw_cfg data register in full words. This speeds up transfers
almost linearly.
