The OpenFirmware device paths that QEMU generates for these disks and
CD-ROMs are very similar to those generated for the i440fx IDE disks and
CD-ROMs (including the same number of devpath nodes necessary for unique
parsing). The interpretations and the translation to UEFI devpath
fragments are different, of course.

When we bind the SATA controller in SataControllerStart(), we read the NP
("Number of Ports") bitfield from the CAP ("HBA Capabilities") register of
the controller. (See the AHCI 1.3.1 spec.)
This register is memory mapped. If we'd like to access it, we must at
least enable memory space access for the device. In addition, Feng Tian
recommended enabling Bus Master DMA in
<http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10545/focus=10659>.
We also enable IO space access for completeness.
Further, because we change the PCI attributes of the device with the above
when binding it, we must also restore its original PCI attributes when
unbinding it. See the Driver Writer's Guide for UEFI 2.3.1 v1.01, section
18.3 "PCI drivers" | 18.3.2 "Start() and Stop()".
(OvmfPkg's copy of SataControllerDxe differs from the same in DuetPkg
because Duet inherits a pre-configured SATA controller from the BIOS, as
explained by Feng. Technically, DuetPkg's SataControllerDxe could also
apply the technique seen in this patch.)

In the next patch we'll add another PCI operation to
SataControllerStart(), which, on error, has to be rolled back similarly to
other actions already being done in SataControllerStart(). Since that PCI
operation won't provide a non-NULL pointer on success, its rollback isn't
really suitable for the current error handling in SataControllerStart().
Employ the traditional cascading labels instead.

Edk2 maintainers reached the consensus that SataControllerDxe was
inherently platform specific, for which reason it was not appropriate for
either PcAtChipsetPkg nor MdeModulePkg. Hence, if OvmfPkg wanted to use
it, it should either reference it directly from under DuetPkg, or copy it.
Given that DuetPkg is another "leaf" platform in edk2, and that in the
upcoming patches we'll actually modify the driver, the ultimate decision
(reached months ago on the list, after Reza's v2 posting) is that OvmfPkg
shall copy the driver.
This patch does that; the only difference being a fresh FILE_GUID in the
INF file.

Since PcdPropertiesTableEnable is used by the DXE Core (in the
InstallPropertiesTable() function, which runs at End-of-Dxe), we must also
change the PcdLib class resolution for that module, from the default
BasePcdLibNull to DxePcdLib.
Traditionally we've considered the DXE Core to be incapable of accessing
dynamic PCDs -- the PCD PPI is not available any longer to the DXE Core,
and the PCD Protocol is not available to it *yet*. There are exceptions
however: if the DXE Core can ensure, by whatever means, that the PCD
Protocol *is* available, then DxePcdLib will just work (the latter even
lists DXE_CORE as an allowed client module type). Namely, DxePcdLib looks
up the PCD Protocol dynamically, on the first library call that actually
needs it (for accessing a dynamic PCD); the lookup doesn't occur in a
library constructor.
And because the DXE Core fetches PcdPropertiesTableEnable at End-of-Dxe,
the PCD Protocol is definitely available then.
In addition, we change the default value of PcdPropertiesTableEnable from
the inherited TRUE to FALSE. It makes no difference at this point (our
runtime DXE drivers are not built with the required 4KB section alignment
anyway), but it's better to be clear about this. The properties table
feature requires OS compatibility, and it breaks Windows 7 minimally.
Therefore the default should be FALSE.

The logic we have in place for i440fx does not work reliably on q35. For
example, if the guest has 2GB of RAM, we allow the PCI root bridge driver
to allocate the legacy video RAM BAR from the [2048 MB, 2816 MB] range,
which falls strictly outside of the Q35 PCI host MMIO aperture that QEMU
configures, and advertizes in ACPI.
In turn, PCI BARs that exist outside of the PCI host aperture that is
exposed in ACPI break Windows guests.
Allocating PCI MMIO resources at or above 3GB on Q35 ensures that we stay
within QEMU's aperture. (See the "w32.begin" assignments in
"hw/pci-host/q35.c".) Furthermore, in pc_q35_init() (file
"hw/i386/pc_q35.c"), QEMU ensures that the low RAM never "leaks" above
3GB.
The i440fx logic is left unchanged.
The Windows guest malfunction on Q35 was reported by Jon Panozzo of Lime
Technology, Inc.

We have an old bug in BootModeInitialization(): firmware is supposed to
clear the CMOS register 0xF after reading it for the last time. QEMU only
sets this register to 0xFE in "hw/timer/mc146818rtc.c", function
rtc_notify_suspend(), and never clears it. However, SeaBIOS does clear it
in "src/post.c" and "src/resume.c", so let's follow suit.
We've never noticed this until now because the register gets mysteriously
cleared on non-resume reboots when OVMF runs on qemu-system-x86_64. But on
qemu-system-i386, this bug breaks a (suspend, resume, reboot) triplet:
after the last step OVMF thinks it's resuming because when it actually
resumed (in the middle step), it failed to clear the register.
BootModeInitialization() is the perfect function to clear the register,
right after setting mBootMode: the function is executed on both normal
boot and on S3 resume; it succeeds DebugDumpCmos() -- so the dump is not
affected by this patch --; and everything that relies on S3 vs. normal
boot after we clear the register uses mBootMode anyway.

SVN rev 18166 ("MdeModulePkg DxeIpl: Add stack NX support") enables
platforms to request non-executable stack for the DXE phase, by setting
PcdSetNxForStack to TRUE.
The PCD defaults to FALSE, because:
(a) A non-executable DXE stack is a new feature and causes changes in
behavior. Some platform could rely on executing code from the stack.
(b) The code enabling NX in the DXE IPL PEIM enforces the
PcdSetNxForStack ==> PcdDxeIplBuildPageTables
implication for "64-bit PEI + 64-bit DXE" platforms, with a new
ASSERT(). Some platform might not comply with this requirement
immediately.
Regarding (a), in none of the OVMF builds do we try to execute code from
the stack.
Regarding (b):
- In the OvmfPkgX64.dsc build (which is where (b) applies) we simply
inherit the PcdDxeIplBuildPageTables|TRUE default from
"MdeModulePkg/MdeModulePkg.dec". Therefore we can set PcdSetNxForStack
to TRUE.
- In OvmfPkgIa32X64.dsc, page tables are built by default for DXE. Hence
we can set PcdSetNxForStack to TRUE.
- In OvmfPkgIa32.dsc, page tables used not to be necessary until now.
After we set PcdSetNxForStack to TRUE in this patch, the DXE IPL will
construct page tables even when it is built as part of OvmfPkgIa32.dsc,
provided the (virtual) hardware supports both PAE mode and the XD bit.
Should this setting cause problems in a GPU (or other device) passthru
scenario, with a UEFI_DRIVER in the PCI option rom attempting to execute
code from the stack, the feature can be dynamically disabled on the QEMU
command line, with "-cpu <MODEL>,-nx".

This commit introdues a new build option to OvmfPkg: HTTP_BOOT_ENABLE.
When HttpBoot is enabled, a new Network boot option will show in the
boot manager menu with the device path like this:
PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)/Uri()
It works like the PXE one but fetches the NBP from the given http
url instead of the tftp service.
A simple testing environment can be set up with the QEMU tap network
and dnsmasq + lighttpd.
Here is the example of the dnsmasq config:
interface=<tap interface>
dhcp-range=192.168.111.100,192.168.111.120,12h
dhcp-option=60,"HTTPClient"
dhcp-boot="http://<tap ip>/<efi file>"
It's similar to the PXE server settings except the tftp function is
disabled, the option 60 must be "HTTPClient", and the boot uri is a
http url.

The Xen code in SmbiosPlatformDxe is centered on the informational HOB
with GUID gEfiXenInfoGuid, and the address constants
XEN_SMBIOS_PHYSICAL_ADDRESS=0x000EB000,
XEN_SMBIOS_PHYSICAL_END=0x000F0000.
This Xen hand-off mechanism is specific to the IA32 and X64 architectures,
and it is very unlikely that a future ARM / AARCH64 implementation would
follow it. Therefore, sequester the IA32 / X64 specific code from the rest
of the source, by renaming "Xen.c" to "X86Xen.c", and adding a
GetXenSmbiosTables() stub function in "ArmXen.c" that returns NULL.
(Those file names are inspired by
"OvmfPkg/Library/XenHypercallLib/X86XenHypercall.c".)
The call site in SmbiosTablePublishEntry() [SmbiosPlatformDxe.c] is aware
that a NULL return value means "Xen SMBIOS tables not found", and will
continue to the QEMU tables (for which the retrieval mechanism is shared
by x86 and Arm).
This change enables SmbiosPlatformDxe for ARM architectures; update the
VALID_ARCHITECTURES comment accordingly.

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.

Call S3Ready() whenever the first of the following occurs:
- a driver signals End-of-Dxe,
- a driver calls EFI_ACPI_S3_SAVE_PROTOCOL.S3Save().
S3Ready() already contains a static, function scope "latch" that causes it
to exit early when called for the second time or later.
(At the moment, the only platform in the edk2 tree that includes this

We are preparing for detaching the S3Ready() functionality from the
EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() protocol member function. Instead, we
will hook the same logic to the End-of-Dxe event group.
The EFI_ACPI_S3_SAVE_PROTOCOL has another member: GetLegacyMemorySize().
According to the documenation,
This function returns the size of the legacy memory (meaning below 1 MB)
that is required during an S3 resume. Before the Framework-based
firmware transfers control to the OS, it has to transition from flat
mode into real mode in case the OS supplies only a real-mode waking
vector. This transition requires a certain amount of legacy memory.
After getting the size of legacy memory below, the caller is responsible
for allocating the legacy memory below 1 MB according to the size that
is returned. The specific implementation of allocating the legacy memory
is out of the scope of this specification.
When EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() is called, the address of the
legacy memory allocated above must be passed to it, in the
LegacyMemoryAddress parameter.
In practice however:
- The S3Ready() function ignores the LegacyMemoryAddress completely.
- No code in the edk2 tree calls
EFI_ACPI_S3_SAVE_PROTOCOL.GetLegacyMemorySize(), ever.
- All callers of this specific implementation of
EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() in the edk2 tree pass a NULL
LegacyMemoryAddress:
BdsLibBootViaBootOption()
[IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
For this reason, ASSERT() explicitly that LegacyGetS3MemorySize() is never
called, and that the LegacyMemoryAddress parameter is always NULL.
This fact is important to capture in the code, because in the End-of-Dxe
callback, no LegacyMemoryAddress parameter can be taken. So let's make it
clear that we actually don't even have any use for that parameter.
This patch ports the identical change from IntelFrameworkModulePkg to
OvmfPkg.

The OFW device path that QEMU exports in the "bootorder" fw_cfg file, for
a device that is plugged into the main PCI root bus, is:
/pci@i0cf8/...
Whereas the same device plugged into the N'th extra root bus results in:
/pci@i0cf8,N/pci-bridge@0/...
(N is in hex.)
Extend TranslatePciOfwNodes() so that it not assume a single PCI root;
instead it parse the extra root bus serial number if present, and resolve
it in the translation to the UEFI devpath fragment.
Note that the "pci-bridge@0" node is a characteristic of QEMU's PXB
device. It reflects the actual emulated PCI hierarchy. We don't parse it
specifically in this patch, because it is automatically handled by the
bridge sequence translator added recently in SVN rev 17385 (git commit
feca17fa4b) -- "OvmfPkg: QemuBootOrderLib: parse OFW device path nodes of
PCI bridges".
The macro EXAMINED_OFW_NODES need not be raised from 6. The longest OFW
device paths that we wish to recognize under this new scheme comprise 5
nodes. The initial "extra root bus" OFW fragment, visible at the top,
takes up 2 nodes, after which the longest device-specific patterns (IDE
disk, IDE CD-ROM, ISA floppy, virtio-scsi disk) take 3 more nodes each.

SeaBIOS requires the OpenFirmware device paths exported in the "bootorder"
fw-cfg file to refer to extra (PXB) root buses by their relative positions
(in increasing bus number order) rather than by actual bus numbers.
However, OVMF's PCI host bridge / root bridge driver creates PciRoot(UID)
device path nodes for extra PCI root buses with UID=bus_nr, not position.
(These ACPI devpath UID values must, and do, match the UID values exposed
in QEMU's ACPI payload, generated for PXB root buses.)
Therefore the boot order matching logic will have to map extra root bus
positions to bus numbers. Add a small group of utility functions to help
with that.

In this patch we assume that root bus number 0 is always there (same as
before), and scan the rest of the extra root buses, up to and including
255. When an extra root bus is found, we install the PCI root bridge IO
protocol for the previous root bus (which might be bus 0 or just the
previous extra root bus).
The root bridge protocol created thus will report the available bus number
range
[own bus number, next extra root bus number - 1]
The LHS of this interval will be used for the root bus's own number, and
the rest of the interval (which might encompass 0 additional elements too)
can be used by the PCI bus driver to assign subordinate bus numbers from.
(Subordinate buses are provided by PCI bridges that hang off the root bus
in question.)
For MMIO and IO space allocation, all the root buses share the original
[0x8000_0000, 0xFFFF_FFFF] and [0x0, 0xFFFF] ranges, respectively.

On output, the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Configuration() function
produces a pointer to a buffer of ACPI 2.0 resource descriptors:
Resources A pointer to the ACPI 2.0 resource descriptors that describe
the current configuration of this PCI root bridge. The
storage for the ACPI 2.0 resource descriptors is allocated by
this function. The caller must treat the return buffer as
read-only data, and the buffer must not be freed by the
caller.
PciHostBridgeDxe currently provides this buffer in a structure with static
storage duration. If multiple root bridges existed in parallel, the
pointers returned by their Configuration() methods would point to the same
static storage. A later Configuration() call would overwrite the storage
pointed out by an earlier Configuration() call (which was possibly made
for a different, but still alive, root bridge.)
Fix this problem by embedding the configuration buffer in
PCI_ROOT_BRIDGE_INSTANCE.
While we're at it, correct some typos (Desp -> Desc), spell out a missing
pack(1) pragma, and improve formatting.

GCC to flag it with a "variable set but not used" warning (which is normally
not visible since as of right now these warnings are supressed). It's true
that the value read into FileReserved is never used, but this is
intentional. This patch adds a do-nothing reference to silence the
warning.

PeiCore hang when loads a PEIM whose section alignment requirement is 0x40
but the actual base address is 0x20 aligned.
The issue is caused by the following facts, in order:
1. GCC49 requires the section alignment of .data to be 0x40. So a new link
script gcc4.9-ld-script was added for GCC49 to specify the 0x40
alignment.
2. GenFw tool was enhanced to sync ELF's section alignment to PE header.
Before the enhancement, the section alignment of converted PE image
always equals to 0x20.
If only with #1 change, GCC49 build image won't hang in PeiCore because
the converted PE image still claims 0x20 section alignment which is
aligned to the align setting set in FDF file. But later with #2 change,
the converted PE image starts to claims 0x40 section alignment, while
build tool still puts the PEIM in 0x20 aligned address, resulting the
PeCoffLoaderLoadImage() reports IMAGE_ERROR_INVALID_SECTION_ALIGNMENT
error.

We are preparing for detaching the S3Ready() functionality from the
EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() protocol member function. Instead, we
will hook the same logic to the End-of-Dxe event group.
The EFI_ACPI_S3_SAVE_PROTOCOL has another member: GetLegacyMemorySize().
According to the documenation,
This function returns the size of the legacy memory (meaning below 1 MB)
that is required during an S3 resume. Before the Framework-based
firmware transfers control to the OS, it has to transition from flat
mode into real mode in case the OS supplies only a real-mode waking
vector. This transition requires a certain amount of legacy memory.
After getting the size of legacy memory below, the caller is responsible
for allocating the legacy memory below 1 MB according to the size that
is returned. The specific implementation of allocating the legacy memory
is out of the scope of this specification.
When EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() is called, the address of the
legacy memory allocated above must be passed to it, in the
LegacyMemoryAddress parameter.
In practice however:
- The S3Ready() function ignores the LegacyMemoryAddress completely.
- No code in the edk2 tree calls
EFI_ACPI_S3_SAVE_PROTOCOL.GetLegacyMemorySize(), ever.
- All callers of this specific implementation of
EFI_ACPI_S3_SAVE_PROTOCOL.S3Save() in the edk2 tree pass a NULL
LegacyMemoryAddress:
BdsLibBootViaBootOption()
[IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
For this reason, ASSERT() explicitly that LegacyGetS3MemorySize() is never
called, and that the LegacyMemoryAddress parameter is always NULL.
This fact is important to capture in the code, because in the End-of-Dxe
callback, no LegacyMemoryAddress parameter can be taken. So let's make it
clear that we actually don't even have any use for that parameter.
This patch ports the identical change from IntelFrameworkModulePkg to
OvmfPkg.

At the moment we work with a UC default MTRR type, and set three memory
ranges to WB:
- [0, 640 KB),
- [1 MB, LowerMemorySize),
- [4 GB, 4 GB + UpperMemorySize).
Unfortunately, coverage for the third range can fail with a high
likelihood. If the alignment of the base (ie. 4 GB) and the alignment of
the size (UpperMemorySize) differ, then MtrrLib creates a series of
variable MTRR entries, with power-of-two sized MTRR masks. And, it's
really easy to run out of variable MTRR entries, dependent on the
alignment difference.
This is a problem because a Linux guest will loudly reject any high memory
that is not covered my MTRR.
So, let's follow the inverse pattern (loosely inspired by SeaBIOS):
- flip the MTRR default type to WB,
- set [0, 640 KB) to WB -- fixed MTRRs have precedence over the default
type and variable MTRRs, so we can't avoid this,
- set [640 KB, 1 MB) to UC -- implemented with fixed MTRRs,
- set [LowerMemorySize, 4 GB) to UC -- should succeed with variable MTRRs
more likely than the other scheme (due to less chaotic alignment
differences).
Effects of this patch can be observed by setting DEBUG_CACHE (0x00200000)
in PcdDebugPrintErrorLevel.

Enabling the DEBUG_GCD (0x00100000) bit in PcdDebugPrintErrorLevel, and

This message is emitted when the DXE core is initializing the memory space

CoreSearchGcdMapEntry() fails because the one entry (with type

The size of this initial entry is determined from the CPU HOB

Set the SizeOfMemorySpace field in the CPU HOB to mPhysMemAddressWidth,
which is the narrowest valid value to cover the entire guest RAM.

We'll soon increase the maximum guest-physical RAM size supported by OVMF.
For more RAM, the DXE IPL is going to build more page tables, and for that
it's going to need a bigger chunk from the permanent PEI RAM.
Otherwise CreateIdentityMappingPageTables() would fail with:
> DXE IPL Entry
> Loading PEIM at 0x000BFF61000 EntryPoint=0x000BFF61260 DxeCore.efi
> Loading DXE CORE at 0x000BFF61000 EntryPoint=0x000BFF61260

(The above example belongs to the artificially high, maximal address width
of 52, clamped by the DXE core to 48. The address width of 48 bits
corresponds to 256 TB or RAM, and requires a bit more than 1GB for paging
structures.)

Git commit 54753b60 (SVN r16870), "MdeModulePkg: Update SMBIOS revision to
3.0." changed PcdSmbiosVersion from 0x0208 to 0x0300. This controls the
version number of the SMBIOS entry point table (and other things) that
"MdeModulePkg/Universal/SmbiosDxe" installs.
Alas, this change breaks older Linux guests, like RHEL-6 (up to RHEL-6.7);
those are limited to 2.x (both in the guest kernel firmware driver, and in
the dmidecode utility). The SMBIOS 3.0 entry point has a different GUID --
defined in UEFI 2.5 -- pointing to it in the UEFI Configuration Table, and
guest kernels that lack upstream kernel commit e1ccbbc9d5 don't recognize
it.
The v2.1.0+ machine types of QEMU generate SMBIOS payload for the firmware
to install. The payload includes the entry point table ("anchor" table).
OvmfPkg/SmbiosPlatformDxe cannot install the anchor table (because that is
the jurisdiction of the generic "MdeModulePkg/Universal/SmbiosDxe"
driver); however, we can parse the entry point version from QEMU's anchor
table, and instruct "MdeModulePkg/Universal/SmbiosDxe" to adhere to that
version.
On machine types older than v2.1.0, the feature is not available, but
then, should anything in OVMF install SMBIOS tables, version 2.8 is simply
safer / more widely supported than 3.0 -- hence the default 2.8 value for
the dynamic PCD.
We set the PCD in PlatformPei (when not on the S3 resume path), because
that's an easy and certain way to set the PCD before a DXE driver reads
it. This follows the example of PcdEmuVariableNvStoreReserved (which is
read by EmuVariableFvbRuntimeDxe).

When the Q35 machine type(s) of QEMU are used with libvirt, libvirt tends
to place some devices behind PCI bridges. This is then reflected in the
"bootorder" fw_cfg file. For example:
/pci@i0cf8/pci-bridge@1e/pci-bridge@1/scsi@5/disk@0,0
/pci@i0cf8/pci-bridge@1e/pci-bridge@1/scsi@3/channel@0/disk@0,0
As yet QemuBootOrderLib doesn't support such OFW device paths.
Add code that translates a sequence of pci-bridge nodes.
In practice libvirt seems to insert two such nodes (*), hence increment
EXAMINED_OFW_NODES with the same number.
(* Background, paraphrasing Laine Stump's words:
When the machine type is Q35, we create a dmi-to-pci bridge coming off of
the pcie root controller, and a pci-to-pci bridge coming off of that, then
attach most devices to the pci-to-pci bridge. This is done because you
can't hotplug into pcie-root, can't (or at least shouldn't) plug a
pci-to-pci bridge into pcie-root (so the next one has to be
dmi-to-pci-bridge), and can't hotplug into dmi-to-pci-bridge (so you need
to have a pci-to-pci bridge).)

It is the responsibility of the SerialPortLib implementation
to deal with flow control if the underlying medium cannot keep
up with the inflow of data.
So in our SerialPortWrite () function, we should spin as long
as we need to in order to deliver all the data instead of giving
up and returning a smaller value than the number of bytes we were
given. Also, remove the 'if (Sent > 0)' condition on the signalling
of the event channel: if the buffer is full and we haven't been able
to add any more data, it makes perfect sense to signal the event
channel again, even if we have done so before when we did write
the data.
Also, this patch brings the implementation of XenSerialPortLib

On PIIX4, function 3, the PMREGMISC register at offset 0x80, with
default value 0x00 has its bit 0 (PMIOSE) indicate whether the PM
IO space given in the PMBA register (offset 0x40) is enabled.
PMBA must be configured *before* setting this bit.
On Q35/ICH9+, function 0x1f, the equivalent role is fulfilled by
bit 7 (ACPI_EN) in the ACPI Control Register (ACPI_CNTL) at offset
0x44, also with a default value of 0x00.
Currently, OVMF hangs when Q35 reboots, because while PMBA is reset
by QEMU, the register at offset 0x80 (matching PMREGMISC on PIIX4)
is not reset, since it has a completely different meaning on LPC.
As such, the power management initialization logic in OVMF finds
the "PMIOSE" bit enabled after a reboot and decides to skip setting
PMBA. This causes the ACPI timer tick routine to read a constant
value from the wrong register, which in turn causes the ACPI delay
loop to hang indefinitely.
This patch modifies the Base[Rom]AcpiTimerLib constructors and the
PlatformPei ACPI PM init routines to use ACPI_CNTL:ACPI_EN instead
of PMREGMISC:PMIOSE when running on Q35.

QEMU commit aa685789 ("xhci: generate a Transfer Event for each Transfer

XHCI emulation is reportedly more virtualization-friendly than EHCI,
consuming less CPU.
The driver can be tested with the following QEMU command line options:

XenHypercallLib has two clients at the moment: XenBusDxe and
XenConsoleSerialPortLib. Currently, when XenBusDxe starts on a non-Xen X86
platform (ie. as part of OVMF not running on Xen), the X86XenHypercallLib
instance built into it fails to initialize, which triggers an ASSERT() in
auto-generated code.
Instead, let's call XenHypercallIsAvailable() in the driver's entry point,
and exit cleanly when the driver is started on a non-Xen platform.
Modify the constructor of XenConsoleSerialPortLib similarly; we shouldn't
proceed if Xen is not available. In practice this check should never fail,
because XenConsoleSerialPortLib is only used on ARM, and
ArmXenHypercallLib is always available; but nonetheless we should be
pedantic.

In the next patch we'll add a simple query function to the XenHypercallLib
library class that is supposed to be called by initialization code in
modules. Among those, in constructors of dependent libraries too.
Library construction ordering is ensured only between libraries with
constructors, plus we shouldn't allow a dependent library with a
constructor to call into any XenHypercallLib instances (the simple query
function) before XenHypercallLib is constructed itself. For this reason,
introduce an (empty) constructor for ARM & AARCH64 too.

prototypes
- moving the discovered hyperpage address to a global variable
- moving XenGetSharedInfoPage() to its only user XenBusDxe.c (the shared info
page is not strictly part of the Xen hypercall interface, and is not used
by other expected users of XenHypercallLib such as the Xen console version
of SerialPortLib
- reimplement XenHypercall2() in C and move the indexing of the hyperpage
there; the existing asm implementations are renamed to __XenHypercall2() and
invoked from the new C implementation.

SVN r16411 delayed ACPI table installation until PCI enumeration was
complete, because on QEMU the ACPI-related fw_cfg files should have been
downloaded only after PCI enumeration. Said commit implemented the
dependency by tightening the module's depex.
This patch replaces the EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL depex with a
matching protocol registration callback. The depex was static, and it
could not handle dynamically discovered situations when the dependency
would turn out invalid.
Namely:
- At the moment, the depex in "QemuFwCfgAcpiPlatformDxe.inf" assumes
that "ArmPlatformPkg/ArmVirtualizationPkg/ArmVirtualizationQemu.dsc"
lacks PCI support. However, PCI support is about to become run-time
discoverable on that platform. If PCI support is missing, then
ArmVirtualizationPkg will set PcdPciDisableBusEnumeration to TRUE.
Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the
dependency by not registering the callback and installing the ACPI
tables right away.
- InitializeXen() in "OvmfPkg/PlatformPei/Xen.c" sets
PcdPciDisableBusEnumeration to TRUE. This causes
PciBusDriverBindingStart() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciBus.c"
to set gFullEnumeration to FALSE, which in turn makes PciEnumerator() in
"MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumerator.c" branch to
PciEnumeratorLight(). The installation of
EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL at the end of PciEnumerator() is
not reached.
Which means that starting with SVN r16411, AcpiPlatformDxe is never
dispatched on Xen.
Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the
dependency by not registering the callback and installing the ACPI
tables right away.

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.)

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.

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.

NOTE: The list of PCI devices for which we initialize PCI_INTERRUPT_LINE

- 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).

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

as ACPI tables.

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.

- the new function InstallAllQemuLinkedTables() calls the former with

The SMBIOS specification requires some structure types to
contain reference fields to other structures' handles. When
InstallAllStructures() rebuilds the SMBIOS tables by traversing
an existing source table, the use of SMBIOS_HANDLE_PI_RESERVED
causes automatically generated, arbitrary handle numbers to be
assigned to each cloned structure. This causes all reference
handle fields to become invalid.
This patch modifies InstallAllStructures() to reuse the original
handle numbers supplied by the underlying VM, preserving the
correctness of any included handle references.

The Windows 2008 R2 SP1 (and Windows 7) UEFI guest's default video driver
dereferences the real mode Int10h vector, loads the pointed-to handler
code, and executes what it thinks to be VGA BIOS services in an internal
real-mode emulator. Consequently, video mode switching doesn't work in
Windows 2008 R2 SP1 when it runs on the pure UEFI build of OVMF, making
the guest uninstallable.
This patch adds a VGABIOS "shim" to QemuVideoDxe. For the first stdvga or
QXL card bound, an extremely stripped down VGABIOS imitation is installed
in the C segment. It provides a real implementation for the few services
that are in fact necessary for the win2k8r2sp1 UEFI guest, plus some fakes
that the guest invokes but whose effect is not important.
The C segment is not present in the UEFI memory map prepared by OVMF. We
never add memory space that would cover it (either in PEI, in the form of
memory resource descriptor HOBs, or in DXE, via gDS->AddMemorySpace()).
This way the handler body is invisible to all non-buggy UEFI guests, and
the rest of edk2.
The Int10h real-mode IVT entry is covered with a Boot Services Code page,
making that too unaccessible to the rest of edk2. (Thus UEFI guest OSes
different from the Windows 2008 family can reclaim the page. The Windows
2008 family accesses the page at zero regardless of the allocation type.)
The patch is the result of collaboration:

- Use OEM mode number (0xf1) instead of standard 800x600 mode (0x143). The

expect anything from it in advance.
- Use 1024x768 rather than 800x600 for more convenience in the Windows

OVMF's SecMain is unique in the sense that it links against the following
two libraries *in combination*:
- IntelFrameworkModulePkg/Library/LzmaCustomDecompressLib/
LzmaCustomDecompressLib.inf
- MdePkg/Library/BaseExtractGuidedSectionLib/
BaseExtractGuidedSectionLib.inf
The ExtractGuidedSectionLib library class allows decompressor modules to
register themselves (keyed by GUID) with it, and it allows clients to
decompress file sections with a registered decompressor module that
matches the section's GUID.
BaseExtractGuidedSectionLib is a library instance (of type BASE) for this
library class. It has no constructor function.
LzmaCustomDecompressLib is a compatible decompressor module (of type
BASE). Its section type GUID is
gLzmaCustomDecompressGuid == EE4E5898-3914-4259-9D6E-DC7BD79403CF
When OVMF's SecMain module starts, the LzmaCustomDecompressLib constructor
function is executed, which registers its LZMA decompressor with the above
GUID, by calling into BaseExtractGuidedSectionLib:
LzmaDecompressLibConstructor() [GuidedSectionExtraction.c]
ExtractGuidedSectionRegisterHandlers() [BaseExtractGuidedSectionLib.c]
GetExtractGuidedSectionHandlerInfo()
PcdGet64 (PcdGuidedExtractHandlerTableAddress) -- NOTE THIS
Later, during a normal (non-S3) boot, SecMain utilizes this decompressor
to get information about, and to decompress, sections of the OVMF firmware
image:
SecCoreStartupWithStack() [OvmfPkg/Sec/SecMain.c]
SecStartupPhase2()
FindAndReportEntryPoints()
FindPeiCoreImageBase()
DecompressMemFvs()
ExtractGuidedSectionGetInfo() [BaseExtractGuidedSectionLib.c]
ExtractGuidedSectionDecode() [BaseExtractGuidedSectionLib.c]
Notably, only the extraction depends on full-config-boot; the registration
of LzmaCustomDecompressLib occurs unconditionally in the SecMain EFI
binary, triggered by the library constructor function.
This is where the bug happens. BaseExtractGuidedSectionLib maintains the
table of GUIDed decompressors (section handlers) at a fixed memory
location; selected by PcdGuidedExtractHandlerTableAddress (declared in
MdePkg.dec). The default value of this PCD is 0x1000000 (16 MB).
This causes SecMain to corrupt guest OS memory during S3, leading to
random crashes. Compare the following two memory dumps, the first taken
right before suspending, the second taken right after resuming a RHEL-7
guest:

The "EGSI" signature corresponds to EXTRACT_HANDLER_INFO_SIGNATURE
declared in
MdePkg/Library/BaseExtractGuidedSectionLib/BaseExtractGuidedSectionLib.c.
Additionally, the gLzmaCustomDecompressGuid (quoted above) is visible at
guest-phys offset 0x1000020.
Fix the problem as follows:
- Carve out 4KB from the 36KB gap that we currently have between
PcdOvmfLockBoxStorageBase + PcdOvmfLockBoxStorageSize == 8220 KB
and
PcdOvmfSecPeiTempRamBase == 8256 KB.
- Point PcdGuidedExtractHandlerTableAddress to 8220 KB (0x00807000).
- Cover the area with an EfiACPIMemoryNVS type memalloc HOB, if S3 is
supported and we're not currently resuming.
The 4KB size that we pick is an upper estimate for
BaseExtractGuidedSectionLib's internal storage size. The latter is
calculated as follows (see GetExtractGuidedSectionHandlerInfo()):
sizeof(EXTRACT_GUIDED_SECTION_HANDLER_INFO) + // 32
PcdMaximumGuidedExtractHandler * (
sizeof(GUID) + // 16
sizeof(EXTRACT_GUIDED_SECTION_DECODE_HANDLER) + // 8
sizeof(EXTRACT_GUIDED_SECTION_GET_INFO_HANDLER) // 8
)
OVMF sets PcdMaximumGuidedExtractHandler to 16 decimal (which is the
MdePkg default too), yielding 32 + 16 * (16 + 8 + 8) == 544 bytes.
Regarding the lifecycle of the new area:
(a) when and how it is initialized after first boot of the VM
The library linked into SecMain finds that the area lacks the signature.
It initializes the signature, plus the rest of the structure. This is
independent of S3 support.
Consumption of the area is also limited to SEC (but consumption does
depend on full-config-boot).
(b) how it is protected from memory allocations during DXE
It is not, in the general case; and we don't need to. Nothing else links
against BaseExtractGuidedSectionLib; it's OK if DXE overwrites the area.
(c) how it is protected from the OS
When S3 is enabled, we cover it with AcpiNVS in InitializeRamRegions().
When S3 is not supported, the range is not protected.
(d) how it is accessed on the S3 resume path
Examined by the library linked into SecMain. Registrations update the
table in-place (based on GUID matches).
(e) how it is accessed on the warm reset path
If S3 is enabled, then the OS won't damage the table (due to (c)), hence
see (d).
If S3 is unsupported, then the OS may or may not overwrite the
signature. (It likely will.) This is identical to the pre-patch status.

Recent qemu versions compose all ACPI tables on the host side, according
to the target hardware configuration, and make the tables available to any
guest firmware over fw_cfg.
See version compatibility information below.
The feature moves the burden of keeping ACPI tables up-to-date from boot
firmware to qemu (which is the source of hardware configuration anyway).
This patch adds client code for this feature. Benefits of the
qemu-provided ACPI tables include PCI hotplug for example.
Qemu provides the following three fw_cfg files:
- etc/acpi/rsdp
- etc/acpi/tables
- etc/table-loader
"etc/acpi/rsdp" and "etc/acpi/tables" are similar, they are only kept
separate because they have different allocation requirements in SeaBIOS.
Both of these fw_cfg files contain preformatted ACPI payload.
"etc/acpi/rsdp" contains only the RSDP table, while "etc/acpi/tables"
contains all other tables, concatenated.
The tables in these two fw_cfg files are filled in by qemu, but two kinds
of fields are left incomplete in each table: pointers to other tables, and
checksums (which depend on the pointers).
Qemu initializes each pointer with a relative offset into the fw_cfg file
that contains the pointed-to ACPI table. The final pointer values depend
on where the fw_cfg files, holding the pointed-to ACPI tables, will be
placed in memory by the guest. That is, the pointer fields need to be
"relocated" (incremented) by the base addresses of where "/etc/acpi/rsdp"
and "/etc/acpi/tables" will be placed in guest memory.
This is where the third file, "/etc/table-loader" comes in the picture. It
is a linker/loader script that has several command types:
One command type instructs the guest to download the other two files.
Another command type instructs the guest to increment ("absolutize") a
pointer field (having a relative initial value) in the pointing ACPI
table, present in some fw_cfg file, with the dynamic base address of the
same (or another) fw_cfg file, holding the pointed-to ACPI table.
The third command type instructs the guest to compute checksums over
ranges and to store them.
In edk2, EFI_ACPI_TABLE_PROTOCOL knows about table relationships -- it
handles linkage automatically when a table is installed. The protocol
takes care of checksumming too. RSDP is installed automatically. Hence we
only need to care about the "etc/acpi/tables" fw_cfg file, determining the
boundaries of each ACPI table inside it, and installing those tables.

The previous patch ensures that the LockBox is protected during DXE (but
the OS can still drop it) if S3 is unsupported or disabled. However, S3
related drivers not only save data in the lockbox, they allocate objects
with Reserved and AcpiNVS memory types too, which the OS can't (must not)
release. This is a waste when S3 is unsupported or disabled.
In OVMF a good "choke point" for these drivers is the entry point of
AcpiS3SaveDxe. The messages of the following commits are relevant to the
data and control flow:
- SVN r15290 (git commit 8f5ca05b)
- SVN r15305 (git commit 5a217a06)
- SVN r15306 (git commit d4ba06df)
Prevent AcpiS3SaveDxe from loading when S3 is unsupported or disabled.
This should keep away (most of the) dependent drivers too.

If Start() succeeds, the callback is only executed when the setup is

If Start() fails, the protocol interface will have been uninstalled

In this patch we populate the form with the two widgets related to video
resolution:
- A read-only string field displaying the preference for the next boot.
- A drop-down list offering choices for changing the setting. This list is
implemented with dynamically generated IFR opcodes.
(In general, the current preference may be missing, or it may be invalid
for the available video RAM size. The list of possible new settings is
filtered with the video RAM size.)
Because the form now becomes able to receive input, we must also implement
ExtractConfig(). This function tells the HII engine about the state of the
widgets.
For now we set up both widgets with static data only:
- The current preference always says "Unset". The driver code is still
isolated from the backend (the UEFI variable store).
- The list of possible resolutions offers 800x600 only. We don't

- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution
Setting the graphics resolution during boot is useful when the guest OS
(for lack of a dedicated display driver) continues to work with the
original GOP resolution and framebuffer.

The two functions introduced here allow the saving and loading of platform
configuration to/from the non-volatile variable store.
The PLATFORM_CONFIG structure and the two functions that take it / return
it are generally meant for any DXE or UEFI driver that needs to access
platform configuration. For now we keep this small "library" internal to
PlatformDxe.
The PLATFORM_CONFIG wire format is intended only to grow over time (as
long as the variable GUID remains unchanged). At the introduction of new
fields, new feature flags must be added, and recognized in
PlatformConfigLoad().

This should plug the leak which, given sufficient reboots, exhausts the

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.)

This driver (from
"MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf")
is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely
as a form of notification), the driver reloads itself to reserved memory.
During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.
The boot script is transferred internal to PiDxeS3BootScriptLib:
Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.

BootScriptExecutorDxe, to be pulled in in the next patch, was written with
the SMM implementation of LockBox in mind. That implementation is split in
the following three parts:
- client side (DXE/PEI) library,
- SMM driver producing gEfiLockBoxProtocolGuid,
- driver side (SMM) library.
BootScriptExecutorDxe includes the client side LockBoxLib. So that the
library can communicate with the SMM LockBox driver, BootScriptExecutorDxe
has a Depex on gEfiLockBoxProtocolGuid, normally installed by the SMM
LockBox driver. This is actually not a hard dependency, it just ensures
correct load order between BootScriptExecutorDxe and
MdeModulePkg/Universal/LockBox/SmmLockBox.
The (client side) LockBox library instance in OVMF doesn't depend on a
separate driver that produces gEfiLockBoxProtocolGuid. Nothing produces
that GUID right now in OVMF. This prevents BootScriptExecutorDxe from
loading.
Install gEfiLockBoxProtocolGuid in our only S3-specific, custom DXE
driver, in order to enable loading of BootScriptExecutorDxe.

The trigger to actually save the boot script is the installation of
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL, to be performed by any DXE driver.
Installation of the protocol also locks down SMM (as its name indicates)
and (in theory) prevents further LockBox access.
We cannot install this protocol before BdsLibBootViaBootOption() is called
(eg. in OVMF's PlatformBdsPolicyBehavior()), because
BdsLibBootViaBootOption() calls EFI_ACPI_S3_SAVE_PROTOCOL.S3Save(), which
needs LockBox access.
We also can't install the protocol after BdsLibBootViaBootOption()
returns, simply because control is never returned to us.
Therefore modify our EFI_ACPI_S3_SAVE_PROTOCOL implementation so that the
boot script is prepared and installed internally to S3Save().
(The boot script must contain at least one opcode, otherwise
S3BootScriptLib runs into an assertion failure. We add a harmless (no-op)
"information" opcode.)

"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.
S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.
The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.
PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.

"IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe/AcpiS3SaveDxe.inf"
currently specifies a DepEx on gEfiMpServiceProtocolGuid (MP Services).
The justification is the following code sequence:
InstallAcpiS3Save()
if PcdFrameworkCompatibilitySupport is set:
InstallAcpiS3SaveThunk()
if EFI_MP_SERVICES_PROTOCOL is available:
GetVariable(ACPI_GLOBAL_VARIABLE)
In English, the AcpiS3SaveDxe driver insists on the presence of MP
Services *unconditionally* because,
- if PcdFrameworkCompatibilitySupport is set (the default is false),
- and MP Services are available (which is constant true under the above
condition),
then the AcpiS3SaveDxe driver would like to get the ACPI_GLOBAL_VARIABLE
variable from the MP Services driver, rather than setting it itself.
The DepEx prevents AcpiS3SaveDxe from loading under OvmfPkg, since we
provide no MP Services implementation. This is particularly broken since
the default PcdFrameworkCompatibilitySupport value is FALSE, making the
entire code that would look at EFI_MP_SERVICES_PROTOCOL dead.
Copy AcpiS3SaveDxe to OvmfPkg, substitute PcdFrameworkCompatibilitySupport
with constant FALSE, and remove all code that becomes dead, including the
DepEx.

The S3 suspend/resume infrastructure depends on the LockBox library class.
The edk2 tree currently contains Null and SMM instances. The Null instance
is useless, and the SMM instance would require SMM emulation by including
the SMM core and adding several new drivers, which is deemed too complex.
Hence add a simple LockBoxLib instance for OVMF.
