Currently we have the following call chain in OVMF:
PlatformBdsPolicyBehavior()
[OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
//
// signals End-of-Dxe
//
OnEndOfDxe() [OvmfPkg/AcpiS3SaveDxe/AcpiS3Save.c]
S3Ready() [OvmfPkg/AcpiS3SaveDxe/AcpiS3Save.c]
//
// 1. saves S3 state
//
SaveS3BootScript() [OvmfPkg/AcpiS3SaveDxe/AcpiS3Save.c]
//
// 2. saves INFO opcode in S3 boot script
// 3. installs DxeSmmReadyToLockProtocol
//
The bottom of this call chain was introduced in git commit 5a217a06 (SVN
r15305, "OvmfPkg: S3 Suspend: save boot script after ACPI context"). That
patch was necessary because there was no other way, due to GenericBdsLib
calling S3Save() from BdsLibBootViaBootOption(), to perform the necessary
steps in the right order:
- save S3 system information,
- save a final (well, only) boot script opcode,
- signal DxeSmmReadyToLock, closing the boot script, and locking down
LockBox and SMM.
The GenericBdsLib bug has been fixed in the previous patch -- the call in
BdsLibBootViaBootOption() has been eliminated.
Therefore, hoist the SaveS3BootScript() code, and call, from
OvmfPkg/AcpiS3SaveDxe, to PlatformBdsLib:
PlatformBdsPolicyBehavior()
[OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
//
// signals End-of-Dxe
//
OnEndOfDxe() [OvmfPkg/AcpiS3SaveDxe/AcpiS3Save.c]
S3Ready() [OvmfPkg/AcpiS3SaveDxe/AcpiS3Save.c]
//
// 1. saves S3 state
//
<---
SaveS3BootScript() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
//
// 2. saves INFO opcode in S3 boot script
// 3. installs DxeSmmReadyToLockProtocol
//
The installation of DxeSmmReadyToLockProtocol belongs with Platform BDS,
not AcpiS3SaveDxe, and we can now undo the hack in SVN r15305, without
upsetting the relative order of the steps.

(Paraphrasing git commit 9cd7d3c5 / SVN r17713:)
Currently, OvmfPkg fails to signal the End-of-Dxe event group when
entering the BDS phase, which results in some loss of functionality, eg.
variable reclaim in the variable driver, and the memory region splitting
in the DXE core that belongs to the properties table feature specified in
UEFI-2.5.
As discussed on the edk2-devel mailing list here:
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109
it is up to the platform BDS to signal End-of-Dxe, since there may be
platform specific ordering constraints with respect to the signalling of
the event that are difficult to honor at the generic level.
(OvmfPkg specifics:)
(1) In OvmfPkg, we can't signal End-of-Dxe before PCI enumeration
completes. According to the previous patch, that would trigger
OvmfPkg/AcpiS3SaveDxe to save S3 state *before* the following chain of
action happened:
- PCI enumeration completes
- ACPI tables are installed by OvmfPkg/AcpiPlatformDxe
- the FACS table becomes available
Since OvmfPkg/AcpiS3SaveDxe can only save S3 state once the FACS table
is available, we must delay the End-of-Dxe signal until after PCI
enumeration completes (ie. root bridges are connected).
(2) Pre-patch, S3Ready() in OvmfPkg/AcpiS3SaveDxe is entered from
BdsLibBootViaBootOption()
[IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c].
After the patch, we enter S3Ready() earlier than that, by signaling
End-of-Dxe in PlatformBdsPolicyBehavior(). The timing / location of
this new call is correct as well, and the original call (that now
becomes the chronologically second call) becomes a no-op: S3Ready() is
protected against 2nd and later entries.

Currently we only connect the root bus with bus number 0, by device path.
Soon we will possibly have several extra root buses, so connect all root
buses up-front (bus number zero and otherwise), by protocol GUID.

The ASSERT() in SetPciIntLine() assumes that Device 0 on "the" root bus
corresponds to the PCI host bridge (00:00). This used to be true, but
because we're going to have extra root buses (with nonzero bus numbers),
soon this assumption may no longer hold. Check for the zero root bus
number explicitly.

Remove hard-coded list of PCI devices for which the Interrupt Line
register is initialized. Instead, provide a "visitor" function to
initialize the register only for present and applicable PCI devices.
At this time, we match the behavior of SeaBIOS (file src/fw/pciinit.c,
functions *_pci_slot_get_irq() and "map the interrupt" block from
pci_bios_init_device()).

Add LNK[A-H] routing target initialization for the Q35 platform.
Additionally, initialize PCI_INTERRUPT_LINE registers for the typical
set of PCI devices included by QEMU with the Q35 machine type. The
corresponding PIIX4 initialization of PCI_INTERRUPT_LINE registers is
cleaned up and the list of PIIX4 PCI devices updated to the list
typically included with QEMU.
NOTE: The list of PCI devices for which we initialize PCI_INTERRUPT_LINE
is hard-coded, and, depending on how QEMU devices are configured on
the command line, may miss some devices, or (harmlessly) attempt to
initialize devices which are not present in the system. A subsequent
patch will replace this hard-coded list with a mechanism to correctly
initialize PCI_INTERRUPT_LINE for applicable present PCI devices only.

PlatformBdsEnterFrontPage() already implements a keypress wait (for
entering the setup utility at boot) with a nice progress bar, only OVMF
has not been using it.
Removing our custom code and utilizing PlatformBdsEnterFrontPage()'s
builtin wait has the following benefits:
- It simplifies OVMF's BDS code.
- Because now we call PlatformBdsEnterFrontPage() unconditionally, it
actually has a chance to look at the EFI_OS_INDICATIONS_BOOT_TO_FW_UI
bit of the "OsIndications" variable, improving compliance with the UEFI
specification. References:
- https://bugzilla.redhat.com/show_bug.cgi?id=1153927
- http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10487
- The progress bar looks nice. (And it keeps the earlier behavior intact,
when the user presses a key on the TianoCore splash screen.)
In any case, we set the timeout to 0 (which doesn't show the progress
bar and proceeds to the boot options immediately) in order to keep the
boot time down.

The second parameter of said function is "ConnectAllHappened", and if set
to TRUE, the function sets "gConnectAllHappened" to TRUE.
This global variable in turn controls whether Intel BDS code *itself*
calls BdsLibConnectAllDriversToAllControllers() in various places -- if
the indicator is TRUE, then the "connect all" is assumed to have been
performed, and Intel BDS doesn't do it itself.
OVMF should pass TRUE as "ConnectAllHappened", because a few lines before
our call to PlatformBdsEnterFrontPage(), we already connect everything
with BdsLibConnectAll(), which includes the effects of
BdsLibConnectAllDriversToAllControllers():
PlatformBdsPolicyBehavior() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
BdsLibConnectAll() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsConnect.c]

The PlatformBdsEnterFrontPage() function's first parameter,
"TimeoutDefault", determines the behavior of the setup utility:
- If (TimeoutDefault == 0), then the usual boot order is to be acted upon
immediately.
- If (TimeoutDefault == 0xFFFF), then the setup utility is entered
unconditionally.
- If (0 < TimeoutDefault && TimeoutDefault < 0xFFFF), then the
PlatformBdsEnterFrontPage() function displays a progress bar, waiting
for TimeoutDefault seconds. If the user presses a key, then the setup
utility is entered, otherwise the normal boot option processing takes
place.
The TimeoutDefault parameter is supposed to be set from
gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPlatformBootTimeOut
which has the following (matching) documentation in
"IntelFrameworkModulePkg/IntelFrameworkModulePkg.dec":
The number of seconds that the firmware will wait before initiating the
original default boot selection.
A value of 0 indicates that the default boot selection is to be
initiated immediately on boot.
The value of 0xFFFF then firmware will wait for user input before
booting.
OVMF does this actually -- see the Timeout variable in
PlatformBdsPolicyBehavior() -- but right before calling
PlatformBdsEnterFrontPage(), OVMF hardwires TimeoutDefault to 0xFFFF.
This has been acceptable until now, because OVMF implements its own "wait
for keypress at the splash screen" logic in PlatformBdsPolicyBehavior(),
completely avoiding the progress bar mentioned above. OVMF only calls
PlatformBdsEnterFrontPage() when the user presses a key during its own
"splash screen wait", and *then* it indeed makes sense to enter the setup
utility unconditionally.
However, even that way, the
Timeout = 0xffff;
assignment is superfluous, because 0xFFFF is already the default value of
PcdPlatformBootTimeOut in "IntelFrameworkModulePkg.dec", and OvmfPkg
doesn't override it in its DSC files.

When PI can distinguish the "full config" boot mode from "assume no
changes", then the following BDS logic is correct:
if BootMode == BOOT_WITH_FULL_CONFIGURATION:
//
// connect all devices
// create & append each default boot option that's missing
//
BdsLibConnectAll
BdsLibEnumerateAllBootOption
else if BootMode == BOOT_ASSUMING_NO_CONFIGURATION_CHANGES:
//
// just stick with current BootOrder and the Boot#### variables
// referenced by it
//
In theory, the first branch is intended to run infrequently, and the
"assume no changes" branch should run most of the time.
However, some platforms can't tell these two boot modes apart. The
following substitute had been introduced:
//
// Technically, always assume "full config", but the BootMode HOB is
// actually meaningless wrt. to "full config" or "assume no changes".
//
ASSERT (BootMode == BOOT_WITH_FULL_CONFIGURATION);
//
// Key off the existence of BootOrder. Try to prepare an in-memory list
// of boot options, based on BootOrder and the referenced Boot####
// variables.
//
Status = BdsLibBuildOptionFromVar()
//
// If that succeeded, we'll treat it as "assume no changes". If it
// failed (*only* if it failed), we'll build default boot options,
// calling it "full config":
//
if EFI_ERROR(Status):
BdsLibConnectAll()
BdsLibEnumerateAllBootOption(BootOptionList)
What we have now in OVMF is a mixture of the hack, and the behavior that's
theoretically correct for "full config":
- We assert "full config" -- this is OK.
- We call "connect all" and "enumerate all" deliberately -- this is OK
too. It matches "full config" which we assert.
- However, we also have the hack in place, which had been meant as an
alternative.
In order to clean this up, we either need to restore the hack to its
original form (ie. comment out the unconditional calls again), or we ought
to remove the hack altogether.
The unconditional "connect all" + "enumerate all" calls are the correct
approach for OVMF, because we want, in fact, to start with "full config".
The QEMU boot order specification and the set of emulated devices might
change "out of band", which excludes "assume no changes".
In other words, removing the hack corresponds to the "real production"
case that the comment hints at.
Because SetBootOrderFromQemu() may change the BootOrder NvVar, we must
preserve the BdsLibBuildOptionFromVar() function call, in order to
refresh the in-memory list with the new boot priorities.
(The last step of BdsLibEnumerateAllBootOption() is such a call too.)

When this option is passed to qemu, it appends the word HALT to the
"bootorder" fw_cfg file, as last entry. For example,
/pci@i0cf8/ethernet@3/ethernet-phy@0
/pci@i0cf8/scsi@4/disk@0,0
HALT
The option's purpose is to prevent SeaBIOS from booting from devices that
have not been specified explicitly (with bootindex=N device properties nor
-boot options). When SeaBIOS sees HALT, it doesn't proceed to boot from
default locations (after boot fails from all of the listed locations).
The HALT string currently causes OVMF to reject the entire "bootorder"
fw_cfg contents, with "parse error". This is not good, because since a
recent libvirt commit, libvirt unconditionally passes "-boot strict=on" to
qemu. Consequently, the boot order logic in QemuBootOrder.c has stopped
working for libvirt users.
OVMF's SetBootOrderFromQemu() function actually implements the idea behind
"-boot strict=on": it drops all boot options not in the fw_cfg list. (*)
Therefore, let's recognize HALT, and just do what we've been doing all
along.
(*) Except the UEFI shell, according to the survival policy in
BootOrderComplete(), but the memory mapped UEFI shell is not expressible
via fw_cfg anyway, and its preservation has been requested on edk2-devel.
Hence it's a good boot option to keep in any case.

QemuFlashFvbServicesRuntimeDxe provides actual persistent storage for
non-volatile variables. When it is active, any on-disk NvVars file counts
as a stale source of variables -- hence don't load these files in BDS.
This also allows Secure Boot settings (eg. enrolled keys) to survive cold
VM reboots.

Some of the active boot options that have not been selected over fw_cfg
should be preserved at the end of the boot order. For now we're adding
back everything that starts with neither PciRoot() nor HD(). This includes
the UEFI shell, memory-mapped from the firmware image.

The prefix matching logic in Match()
[OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c] expects UEFI boot options
to specify full (absolute) device paths. However, partial (relative)
device paths starting with a HD() node are valid for booting. By not
recognizing them, QemuBootOrder.c misses (and deletes) valid boot options
that would otherwise match the user's preference.
Just like BdsLibBootViaBootOption() expands such paths with the
BdsExpandPartitionPartialDevicePathToFull() function for booting, do the
same in QemuBootOrder.c for prefix matching.
This moves the very first call to
BdsExpandPartitionPartialDevicePathToFull() to an earlier point. The
following call tree explains it:
BdsEntry() [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
PlatformBdsPolicyBehavior() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
SetBootOrderFromQemu() [OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c]
Match() [OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c]
BdsExpandPartitionPartialDevicePathToFull() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
BdsBootDeviceSelect() [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
BdsLibBootViaBootOption() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
BdsExpandPartitionPartialDevicePathToFull() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
This should be fine, for two reasons:
- the new, earlier call is still under BdsEntry(),
- BdsExpandPartitionPartialDevicePathToFull() expects to be called
repeatedly, even with the same set of HD() device paths. This function
implements its own caching for device paths, likely for performance
reasons.
That fits this patch well because whatever device paths we expand under
PlatformBdsPolicyBehavior() can be quickly looked up in
BdsBootDeviceSelect(), so no work (ie.
BdsLibConnectAllDriversToAllControllers()) should be wasted.

explicitly initialise, other than the setup_header from 0x1f1 onwards
for a precisely defined length, which is copied from the bzImage.

in the bzImage file surrounding the setup_header.

Set the boot order based on configuration retrieved from QEMU.
Attempt to retrieve the "bootorder" fw_cfg file from QEMU. Translate the
OpenFirmware device paths therein to UEFI device path fragments. Match the
translated fragments against the enumerated BootOptionList, and rewrite
the BootOrder NvVar so that it corresponds to the order described in
fw_cfg.
The user is expected to configure working boot options first.
Tested via virt-manager's boot order widget.

Older QEMU versions would load vgabios-cirrus.bin at 0xc0000 in
system RAM. We would then find this ROM, and try to run it, since
it would be our QEMU Video driver.
Now, the QEMU Video driver is just merged into the main OVMF
firmware image, so this support is unused.

This call can cause a reset, and is most critical for ACPI S3/S4
resume situations. OVMF does not support S3/S4.
OVMF does not have true non-volatile variable support, so
this call could cause a continuous reset situation in certain
scenarios. (The BdsLibSaveMemoryTypeInformation may set an
non-volatile variable, and then reset with the assumption that
the variable will still exist during the next boot.)
Additionally, some version of QEMU appear to hang when the
port 64 reset is initiated.
