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.

Since the TcpDxe, UefiPxeBcDxe, and IScsiDxe drivers in NetworkPkg also
support IPv4, we replace the ones in MdeModulePkg.
To enable the IPv6 support, build OVMF with "-D NETWORK_IP6_ENABLE".

NetworkPkg/IScsiDxe is enabled only if both IPv6 and SecureBoot are enabled.

The ACPI payload that OVMF downloads from QEMU via fw_cfg depends on the
PCI enumaration and resource assignment performed by
MdeModulePkg/Bus/Pci/PciBusDxe.
Namely, although the ACPI payload is pre-generated in qemu during machine
initialization, in
main() [vl.c]
qemu_run_machine_init_done_notifiers()
pc_guest_info_machine_done() [hw/i386/pc.c]
acpi_setup() [hw/i386/acpi-build.c]
acpi_build()
acpi_add_rom_blob()
rom_add_blob(... acpi_build_update ...) [hw/core/loader.c]
fw_cfg_add_file_callback() [hw/nvram/fw_cfg.c]
the ACPI data is rebuilt at the first time any of the related fw_cfg files
are read, through the acpi_build_update() fw_cfg read-callback function:
fw_cfg_read() [hw/nvram/fw_cfg.c]
acpi_build_update() [hw/i386/acpi-build.c]
acpi_build()
(See qemu commit d87072ceeccf4f84a64d4bc59124bcd64286c070 and its
containing series.)
For this reason we must not dispatch AcpiPlatformDxe before PciBusDxe
completes the enumeration.
Luckily, the PI Specification 1.3 defines
EFI_PCI_ENUMERATION_COMPLETE_GUID in Volume 5, "10.9 End of PCI
Enumeration Overview", as an indicia to inform the platform when the PCI
enumeration process has completed. PciBusDxe installs this protocol at the
end of the PciEnumerator() function.
Let's add this GUID to the Depex section of AcpiPlatformDxe, in order to
state the dependency explicitly.
On Xen, and on older QEMU where the linker/loader fw_cfg interface is
unavailable, this introduces a harmless ordering constraint -- we'll
always include PciBusDxe in OVMF, so the dependency will always be
satisfied.
I tested this change as follows:
- I dumped the ACPI tables in a Fedora 20 guest, before and after the
change, and compared them. The only thing that actually changed was the
FACS address. (Which I promptly tested with S3 suspend/resume.) Plus, of
course, the FACP checksum changed, because the FACP links the FACS.
- Tested S3 in my Windows Server 2008 R2 and Windows Server 2012 R2 guests.

When building with VS2010 for Ia32 / NOOPT, the 64-by-32 bit
multiplication is translated to an intrinsic, which is not allowed in
edk2.
Recognize that "Lba" is always bounded by "mFdBlockCount" (an UINTN) here
-- all callers of QemuFlashPtr() ensure that. In addition, the flash chip
in question is always under 4GB, which is why we can address it at all on
Ia32. Narrow "Lba" to UINTN, without any loss of range.

In the InitializeVariableFvHeader() function, all three of "Offset",
"Start" and "BlockSize" have type UINTN. Therefore the (Offset /
BlockSize) and (Start / BlockSize) divisions can be compiled on all
platforms without intrinsics.
In the current expressions
(EFI_LBA) Offset / BlockSize
(EFI_LBA) Start / BlockSize
"Offset" and "Start" are cast to UINT64 (== EFI_LBA), which leads to
64-by-32 bit divisions on Ia32, breaking the VS2010 / NOOPT / Ia32 build.
The simplest way to fix them is to realize we don't need casts at all.
(The prototypes of QemuFlashEraseBlock() and QemuFlashWrite() are visible
via "QemuFlash.h", and they will easily take our UINTN quotients as
UINT64.)

The MarkMemoryRangeForRuntimeAccess() function passes the Length parameter
(of type UINT64) to the macro EFI_SIZE_TO_PAGES(). When building for the
Ia32 platform, this violates the interface contract of the macro:
[...] Passing in a parameter that is larger than UINTN may produce
unexpected results.
In addition, it trips up compilation by VS2010 for the Ia32 platform and
the NOOPT target -- it generates calls to intrinsics, which are not
allowed in edk2.
Fix both issues with the following steps:
(1) Demote the Length parameter of MarkMemoryRangeForRuntimeAccess() to
UINTN. Even a UINT32 value is plenty for representing the size of the
flash chip holding the variable store. Length parameter is used in the
following contexts:
- passed to gDS->RemoveMemorySpace() -- takes an UINT64
- passed to gDS->AddMemorySpace() -- ditto
- passed to EFI_SIZE_TO_PAGES() -- requires an UINTN. This also guarantees
that the return type of EFI_SIZE_TO_PAGES() will be UINTN, hence we can
drop the outer cast.
(2) The only caller of MarkMemoryRangeForRuntimeAccess() is
FvbInitialize(). The latter function populates the local Length variable
(passed to MarkMemoryRangeForRuntimeAccess()) from
PcdGet32(PcdOvmfFirmwareFdSize). Therefore we can simply demote the local
variable to UINTN in this function as well.
- There's only one other use of Length in FvbInitialize(): it is passed to
GetFvbInfo(). GetFvbInfo() takes an UINT64, so passing an UINTN is fine.

Merge PciInitialization() and AcpiInitialization() into a single
function, PciAcpiInitialization(), and use a PCD set during PEI to
detect the underlying platform type (PIIX4 or Q35/MCH) and therefore
the addresses of the registers to be initialized.
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.

- BaseRom: used during SEC, PEI_CORE, and PEIM;
- Dxe: used during DXE_DRIVER and DXE_RUNTIME_DRIVER;
- Base: used by default during all other stages.
Most of the code remains in AcpiTimerLib.c, to be shared by all
instances. The two platform-dependent methods (constructor and
InternalAcpiGetTimerTick) are provided separately by source files
specific to each instance, namely [BaseRom|Base|Dxe]AcpiTimerLib.c.
Since pre-DXE stages can't rely on storing data in global variables,
methods specific to the "BaseRom" instance will call platform
detection macros each time they're invoked.
The "Base" instance calls platform detection macros only from its
constructor, and caches the address required by InternalAcpiTimerTick
in a global variable.
The "Dxe" instance is very similar to "Base", except no platform
detection macros are called at all; instead, the platform type is
read via a dynamic PCD set from PlatformPei.

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.

This patch imports publics headers in order to use features from Xen
like XenStore, PV Block... There is only the necessary header files and
there are only a few modifications in order to facilitate future merge of
more recent header (that would be necessary to access new features).
There is little modification compared to the original files:
- Removed most of the unused part of the headers
- Use of ZeroMem() instead of memset()
- using #pragma pack(4) for IA32 compilation.
- Replace types to be more UEFI compliant using a script.
OVMF, when built for IA32 arch, uses the gcc switch -malign-double. This
change the alignment of fields in some struct compare to what is
espected by Xen and any backends. To fix the alignment, the #pragma pack(4)
directive is used around the struct that need it.
Command to run to change types:
find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed
--regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \;
Avoid changing the 'long' that is not a type (with the first line).

The commit message is not overly verbose:
OvmfPkg: Add custom SecureBootConfigDxe that doesn't reset
We don't force a platform reset for OVMF when PK is changed in custom
mode setup.
But the INF file hunk is telling:
Need custom SecureBootConfigDxe for OVMF that does not force resets
after PK changes since OVMF doesn't have persistent variables
We do have persistent variables now. Let's disable the (now obsolete)
OvmfPkg fork, and revert to the (well maintained) SecurityPkg-provided
config driver.

Recent changes in the QEMU ACPI table generator have shown that our
limited client for that interface is insufficient and/or brittle.
Implement the full interface utilizing OrderedCollectionLib for addressing
fw_cfg blobs by name.
In order to stay compatible with EFI_ACPI_TABLE_PROTOCOL, we don't try to
identify QEMU's RSD PTR and link it into the UEFI system configuration
table. Instead, once all linker/loader commands have been processed, we
process the AddPointer commands for a second time.
In the second pass, we look at the targets of these pointer commands. The
key idea (by Michael Tsirkin) is that any ACPI interpreter will only be
able to locate ACPI tables by following absolute pointers, hence QEMU's
set of AddPointer commands will cover all of the ACPI tables (and more,
see below).
Some of QEMU's AddPointer commands (ie. some fields in ACPI tables) may
point to areas in fw_cfg blobs that are not ACPI tables themselves.
Examples are the BGRT.ImageAddress field, and the TCPA.LASA field. We tell
these apart from ACPI tables by performing the following checks on pointer
target "candidates":
- length check against minimum ACPI table size, and remaining blob size
- checksum verification.
If a target area looks like an ACPI table, and is different from RSDT and
DSDT (which EFI_ACPI_TABLE_PROTOCOL handles internally), we install the
table (at which point EFI_ACPI_TABLE_PROTOCOL creates a deep copy of the
relevant segment of the pointed-to fw_cfg blob).
Simultaneously, we keep account if each fw_cfg blob has ever been
referenced as the target of an AddPointer command without that AddPointer
command actually identifying an ACPI table. In this case the containing
fw_cfg file (of AcpiNVS memory type) must remain around forever, because
we never install that area with EFI_ACPI_TABLE_PROTOCOL, but some field in
some ACPI table that we *do* install still references it, by the absolute
address that we've established during the first pass.

In the next patch we rewrite the client code for QEMU's fw_cfg ACPI table
loader interface. In order to avoid randomly intermixed hunks in that
patch, first remove the old code cleanly.
We remove the InstallQemuLinkedTables() function and empty the
InstallAllQemuLinkedTables() function. We also remove CheckRsdp().
InstallAllQemuLinkedTables() will return constant EFI_NOT_FOUND to
AcpiPlatformEntryPoint(), causing the latter to proceed to OVMF's builtin
tables.
This way the history remains bisectable and the new client gets a clean
start in the next patch.

When setting up the list of GOP modes offered on QEMU's stdvga ("VGA") and
QXL ("qxl-vga") video devices, QemuVideoBochsModeSetup() filters those
modes against the available framebuffer size. (Refer to SVN r15288 / git
commit ec88061e.)
The VBE_DISPI_INDEX_VIDEO_MEMORY_64K register of both stdvga and QXL is
supposed to report the size of the drawable, VGA-compatibility
framebuffer. Instead, up to and including qemu-2.1, this register actually
reports the full video RAM (PCI BAR 0) size.
In case of stdvga, this happens to be correct, because on that card the
full PCI BAR 0 is usable for drawing; there is no difference between
"drawable framebuffer size" and "video RAM (PCI BAR 0) size".
However, on the QXL card, only an initial portion of the video RAM is
suitable for drawing, as compatibility framebuffer; and the value
currently reported by VBE_DISPI_INDEX_VIDEO_MEMORY_64K overshoots the
valid size. Beyond the drawable range, the video RAM contains buffers and
structures for the QXL guest-host protocol.
Luckily, the size of the drawable QXL framebuffer can also be read from a
register in the QXL ROM BAR (PCI BAR 2), so let's retrieve it from there.
Without this fix, OVMF offers too large resolutions on the QXL card (up to
the full size of the video RAM). If a GOP client selects such a resolution
and draws into the video RAM past the compatibility segment, then the
guest corrupts its communication structures (which is invalid guest
behavior).

Lack of these braces causes build errors when -Wno-missing-braces is
absent. Spelling out more braces also helps understanding the code.

The fw_cfg file "etc/acpi/tables" is not a stable guest interface -- QEMU
could rename it in the future, and/or introduce additional fw_cfg files
with ACPI payload. Only the higher-level "etc/table-loader" file is
considered stable, which contains a sequence of commands to assist
firmware with reading QEMU ACPI tables from the FwCfg interface.
Because edk2 provides publishing support for ACPI tables, OVMF only uses
the Allocate command to find the names of FwCfg files to read and publish
as ACPI tables.

In one of the next patches we'll start scanning all fw_cfg files that QEMU
advertises as carrying ACPI tables, not just "etc/acpi/tables".
The RSD PTR table is known to occur in the "etc/acpi/rsdp" fw_cfg file.
Since edk2 handles RSD PTR automatically, similarly to RSDT and XSDT,
let's exclude RSD PTR too from the manually installed tables.

Split InstallQemuLinkedTables() in two:
- the function now takes the name of the fw_cfg file (from which ACPI
tables are to be extracted) as a parameter,
- the new function InstallAllQemuLinkedTables() calls the former with
fw_cfg file names, and cumulatively tracks the ACPI tables installed by
all invocations of the former.

Names of firmware configuration files always take 56 bytes (including at
least one terminating NUL byte). Expose this constant to all consumers of
QemuFwCfgLib because further interfaces may depend on it.
