The main observation about the 64-bit PCI host aperture is that it is the
highest part of the useful address space. It impacts the top of the GCD
memory space map, and, consequently, our maximum address width calculation
for the CPU HOB too.
Thus, modify the GetFirstNonAddress() function to consider the following
areas above the high RAM, while calculating the first non-address (i.e.,
the highest inclusive address, plus one):
- the memory hotplug area (optional, the size comes from QEMU),
- the 64-bit PCI host aperture (we set a default size).
While computing the first non-address, capture the base and the size of
the 64-bit PCI host aperture at once in PCDs, since they are natural parts
of the calculation.
(Similarly to how PcdPciMmio32* are not rewritten on the S3 resume path
(see the InitializePlatform() -> MemMapInitialization() condition), nor
are PcdPciMmio64*. Only the core PciHostBridgeDxe driver consumes them,
through our PciHostBridgeLib instance.)
Set 32GB as the default size for the aperture. Issue#59 mentions the
NVIDIA Tesla K80 as an assignable device. According to nvidia.com, these
cards may have 24GB of memory (probably 16GB + 8GB BARs).
As a strictly experimental feature, the user can specify the size of the
aperture (in MB) as well, with the QEMU option
-fw_cfg name=opt/ovmf/X-PciMmio64Mb,string=65536
The "X-" prefix follows the QEMU tradition (spelled "x-" there), meaning
that the property is experimental, unstable, and might go away any time.
Gerd has proposed heuristics for sizing the aperture automatically (based
on 1GB page support and PCPU address width), but such should be delayed to
a later patch (which may very well back out "X-PciMmio64Mb" then).
For "everyday" guests, the 32GB default for the aperture size shouldn't
impact the PEI memory demand (the size of the page tables that the DXE IPL
PEIM builds). Namely, we've never reported narrower than 36-bit addresses;
the DXE IPL PEIM has always built page tables for 64GB at least.
For the aperture to bump the address width above 36 bits, either the guest
must have quite a bit of memory itself (in which case the additional PEI
memory demand shouldn't matter), or the user must specify a large aperture
manually with "X-PciMmio64Mb" (and then he or she is also responsible for
giving enough RAM to the VM, to satisfy the PEI memory demand).

Now that the previous patches ensure that we can access all PCI devices in
AcpiPlatformDxe, we can enable IO and MMIO decoding for all of them while
we contact QEMU for the ACPI tables. See more details in the patch titled:
OvmfPkg: introduce gRootBridgesConnectedEventGroupGuid
In particular, this patch will prevent the bug when the 64-bit MMIO
aperture is completely missing from QEMU's _CRS, and consequently Linux
rejects 64-bit BARs with the error message
pci 0000:00:03.0: can't claim BAR 4 [mem 0x800000000-0x8007fffff 64bit

This patch doesn't change the behavior of AcpiPlatformDxe when
PcdPciDisableBusEnumeration is TRUE -- that is, when the driver runs on
Xen (OvmfPkg and ArmVirtPkg both), or when the driver runs on QEMU as part
of ArmVirtPkg but no PCI host bridge was found by VirtFdtDxe. In these
cases the driver continues to install the ACPI tables immediately.
However, when PcdPciDisableBusEnumeration is FALSE (i.e., when the driver
runs on QEMU as part of OVMF, or as part of ArmVirtPkg and VirtFdtDxe
finds a PCI host bridge), we now delay the ACPI table download from QEMU.
We wait until the Platform BDS tells us that root bridges have been
connected, and PciIo instances are available.
The explanation is in the patch titled

QEMU's ACPI table generator can only create meaningful _CRS objects --
apertures -- for the root buses if all of the PCI devices behind those
buses are actively decoding their IO and MMIO resources, at the time of
the firmware fetching the "etc/table-loader" fw_cfg file. This is not a
QEMU error; QEMU follows the definition of BARs (which are meaningless
when decoding is disabled).
Currently we hook up AcpiPlatformDxe to the PCI Bus driver's
gEfiPciEnumerationCompleteProtocolGuid cue. Unfortunately, when the PCI
Bus driver installs this protocol, it's *still* not the right time for
fetching "etc/table-loader": although resources have been allocated and
BARs have been programmed with them, the PCI Bus driver has also cleared
IO and MMIO decoding in the command registers of the devices.
Furthermore, we couldn't reenable IO and MMIO decoding temporarily in our
gEfiPciEnumerationCompleteProtocolGuid callback even if we wanted to,
because at that time the PCI Bus driver has not produced PciIo instances
yet.
Our Platform BDSes are responsible for connecting the root bridges, hence
they know exactly when the PciIo instances become available -- not when
PCI enumeration completes (signaled by the above protocol), but when the
ConnectController() calls return.
This is when our Platform BDSes should explicitly cue in AcpiPlatformDxe.
Then AcpiPlatformDxe can temporarily enable IO and MMIO decoding for all
devices, while it contacts QEMU for the ACPI payload.
This patch introduces the event group GUID that we'll use for unleashing
AcpiPlatformDxe from our Platform BDSes.

So refactor this code into a single macro, and expand it into each vector

longer patched in by the C code, we can just emit the literal into each

This is an emergency fix for UINT64 multiplications and divisions not
being done with the right BaseLib functions -- they break Ia32 builds.

Introduce ARM and AArch64 instances of the CpuExceptionHandlerLib which
provides exception handling and registration of handlers regardless of
execution phase.
Two variants of the ArmExceptionLib are provided: one where exception
handlers reside within the module (meeting appropriate architectural
alignment requirements for the vector table) and another one that will
relocate a copy of thee xception handlers to an address specified by
PcdCpuVectorBaseAddress. The ArmRelocateExceptionLib is intended for use
in cases where ArmExceptionLib is too large for the application
(uncompressed XIP images) as driven by the vector table alignment padding.
The AArch64 build of this library supports execution at EL1, EL2, and EL3
exception levels.
Tested on ARM, and AArch64 with SEC, DXE Core, and CpuDxe modules.

ConSplitter's Absolute Pointer should scale virtual device's resolution like what Simple Pointer do.
Before this change, caller will get Virtual device's resolution but physical device's current point.
This change let caller get Virtual device's resolution with virtual device's current point.

This patch makes Shell support -nonesting invocation option. This option
specifies that EFI_SHELL_PROTOCOL.Execute API nesting of a new Shell
instance is optional and dependent on the 'nonesting' Shell environment
variable.

The HTTP Boot driver have some UEFI driver model problems which will make the
code ASSERT when it's disconnected.
First, the driver opens the HttpSb protocol BY_CHILD without BY_DRIVER attribute.
So the driver binding stop won't be called when HTTP driver is disconnected, so
a child handle is left and made HTTP driver binding stop function goes into error.
This patch remove this unnecessary OpenProtocol and only unload the HII from when
both the IP4 and IP6 stack have been stopped completely.
The second issue is the HTTP boot driver always use the driver's image handle as
it's driver binding handle, it's not correct. HTTP Boot driver provides 2 separate
driver binding protocols from IP4 and IP6 stack, so it has 2 driver binding handle.
So this patch fix the code to use correct driver binding handle when create/open
a HTTP child handle.
