The only observeable effect of having PcdPerformanceLibraryPropertyMask
set to 1 is that a EfiReservedMemory region of 4 pages is allocated right
below the 4 GB mark. This region is out of bounds for the OS, which means
it is not even allowed to map it, to avoid speculative loads from it.
On Linux, this may prevent the kernel from using a 1 GB block mapping for
this region, and instead it has to carve up the block as follows:
0xffffffff80000000-0xffffffffbe000000 992M PMD CON BLK
0xffffffffbe000000-0xffffffffbfe00000 30M PMD BLK
0xffffffffbfe00000-0xffffffffbfff0000 1984K PTE CON
0xffffffffbfff0000-0xffffffffbfffc000 48K PTE
where it would otherwise use a single 1 GB mapping (*), i.e.,
0xffffffff80000000-0xffffffffc0000000 1G PGD
To clarify, the latter is a single 8 byte entry in the top level page
table, whereas in the former case, we have two additional levels of
paging, requiring two extra 4 KB pages (on a 4 KB pagesize kernel).
The real cost, however, is the TLB footprint, which goes up from a
single entry to a number between 90 and 1020, depending on whether
contiguous hints are honoured by the hardware.
So let's remove PcdPerformanceLibraryPropertyMask until we find a reason
why we need it.
(*) provided that no other allocations were deliberately located right
below the 4 GB mark, and that we are running with more than 3 GB of
memory, in which case most allocations will be over 4 GB, given EDK2's
default top-down allocation policy.

The debug implementation of the UncachedMemoryAllocationLib library
class relies on the creation of an uncached alias of a memory range,
while keeping the original cached mapping, but with read-only attributes
to trap inadvertent write accesses.
This is not a terribly good idea, given that the ARM architecture does
not allow mismatched attributes, and so creating them deliberately is
not something we should encourage by doing it in reference code.
So remove the library, and replace all references to it with a reference
to the non-debug version (unless the platform does not require a resolution
for it in the first place, in which case all UncachedMemoryAllocationLib
references can be removed altogether).

- introduce the new function typedef WRITE_BYTES_FUNCTION,
- extract the current (MMIO-only) write internals from

- provide a DMA-based implementation in DmaWriteBytes() -- a thin wrapper

- EFI_COMPONENT_NAME_PROTOCOL
- EFI_COMPONENT_NAME2_PROTOCOL
- EFI_DRIVER_CONFIGURATION_PROTOCOL
- EFI_DRIVER_CONFIGURATION2_PROTOCOL

- EFI_DRIVER_DIAGNOSTICS2_PROTOCOL
The UefiLib functions
- EfiLibInstallAllDriverProtocols()
- EfiLibInstallAllDriverProtocols2()
- EfiLibInstallDriverBindingComponentName2()
are convenience helpers for such UEFI_DRIVERs. They simplify the
installation of the above protocols.
The UefiLib instance in "MdePkg/Library/UefiLib/UefiDriverModel.c" allows
platforms to control these functions through the MdePkg feature PCDs
- PcdComponentNameDisable
- PcdComponentName2Disable
- PcdDriverDiagnosticsDisable
- PcdDriverDiagnostics2Disable
If any of these PCDs are set to TRUE, then the helper functions will not
install the corresponding protocol interfaces on the image handle, even if
the driver passes in non-NULL protocol interfaces.
In other words, at build time, a platform can forcibly prevent all drivers
that employ UefiLib from producing these protocols.
In ArmVirtPkg, that's what we've been doing forever, for no reason at all.
This is why we haven't been seeing component and driver names from the DH,
DEVICES, DRIVERS and DEVTREE shell commands, unlike in OvmfPkg.
The default value for all these PCDs is FALSE, in "MdePkg/MdePkg.dec".
Revert ArmVirtPkg to the sane defaults.

Setting the linux,pci-probe-only was intended to align OSes booting via

performed by the firmware. However, ACPI on arm64 does not currently honor
the firmware's PCI configuration, and the linux,pci-probe-only completely
prevents any PCI reconfiguration from occurring under the OS, including
what is needed to support PCI hotplug.
Since the primary use case was OS access to the GOP framebuffer (which
breaks when the framebuffer BAR is moved when the OS reconfigures the
PCI), we can undo this change now that ArmVirtQemu has moved to a GOP
implementation that does not expose a raw framebuffer in the first place.

The clang developers have made a backward incompatible change to the
command line arguments, and have replaced '-mllvm -arm-use-movt=0'
with '-mno-movt'. This does not matter for most ARM platforms, and
therefore it has been removed from the default CLANG35/ARM CC flags
in patch 1c63516075 ("BaseTools CLANG35: drop problematic use-movt
and save-temps options"), but as it turns out, the relocatable PrePi
implementation used by ArmVirtQemuKernel and ArmVirtXen will fail to
build if it contains MOVT/MOVW pairs, due to the fact that these are
not runtime relocatable under ELF.
Since they are runtime relocatable under PE/COFF, and GenFw does the
right thing when encountering them, selectively controlling their
use is more appropriate than disabling them altogether. Therefore,
this patch adds the -mno-movt argument only for the platforms that
use the relocatable PrePi, and only for the module types that may
be pulled into its build.
In addition, switch to the SEC type version of ArmLib, so that
the relocatable PrePi only depends on BASE and SEC type libraries.

Commit b89919ee8f ("BaseTools AARCH64: override XIP module linker
alignment to 32 bytes") updated the various AARCH64 toolchain definitions
to allow SEC, PEI_CORE and PEIM modules to be built with minimal alignment
requirements even when using the AArch64 small code model which normally
requires 4 KB section alignment.
This involves conversion of ADRP instructions into ADR instructions, which
can only be done reliably if the ELF and the PE/COFF sections appear at
the same offset modulo 4 KB.
The ArmVirtPrePiUniCoreRelocatable linker script did not yet take this
into account, so update it by starting the .text section at the next
appropriately aligned offset PECOFF_HEADER_SIZE bytes into the image.

Newer versions of ld automatically emit .gnu.hash and .note.gnu.build-id

Since we don't require or care about these sections, update the linker

Remove any boot options that point to binaries built into the firmware and

- FvMain's base address or size changed (historical -- see commit
e191a3114f),
- FvMain's FvNameGuid changed,
- the FILE_GUID of the pointed-to binary changed,
- the referenced binary is no longer built into the firmware.
For example, multiple such "EFI Internal Shell" boot options can coexist.
They technically differ from each other, but may not describe any built-in
shell binary exactly. Such options can accumulate in a varstore over time,
and while they remain generally bootable (thanks to the efforts of
BmGetFileBufferByFvFilePath()), they look bad.
Filter out any stale options.

- the user specifies no boot order via fw_cfg at all (so QemuBootOrderLib

- the varstore file has just been created from the varstore template.
In this case the user is dropped to the UEFI shell (because the shell is

- BootLogoLib: provides the BootLogoEnableLogo() function. It does not

delegated to ImageDecoderLib (function DecodeImage()).
- ImageDecoderLib: a general library that registers decoder plugins for
specific image formats, and provides the generic DecodeImage() on top.
- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
(which is the format of our logo).
In this patch, we revert 1f73aef50c, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

- QemuBootOrderLib is pointed to the QemuNewBootOrderLib instance.
- FileExplorerLib no longer depends on SECURE_BOOT_ENABLE, it is nedeed by

QemuBootOrderLib can only filter out and reorder boot options; it cannot
create boot options. It relies on Platform BDS to auto-generate all
possible boot options first (for example, for new virtual devices that
have been configured since the last run of the virtual machine). Then it
will decide, case-by-case, whether each of those auto-generated boot
options should be preserved (and at what position), or removed.
Thus far, the only implementation of SetBootOrderFromQemu(), used in
connection with IntelFrameworkModulePkg BDS, has expected said complete
boot option list as an input parameter:
BdsEntry() [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
// create empty list
InitializeListHead (
&BootOptionList
)
PlatformBdsPolicyBehavior( [ArmVirtPkg/Library/PlatformIntelBdsLib/IntelBdsPlatform.c]
BootOptionList
)
BdsLibConnectAll()
BdsLibEnumerateAllBootOption(
BootOptionList
)
// at this point, BootOptionList starts with the preexistent boot
// options, and ends with the auto-generated options
SetBootOrderFromQemu( [OvmfPkg/Library/QemuBootOrderLib/QemuBootOrderLib.c]
BootOptionList
)
// write out changed boot order to UEFI variables
// The "BootOrder" variable may have changed. Refresh BootOptionList
// from it, and return it to BdsEntry().
With MdeModulePkg BDS, a BootOptionList is not propagated from BdsEntry()
to SetBootOrderFromQemu() and back. All processing is based directly on
the underlying "BootOrder" and "Boot####" variables.
In OvmfPkg, commit d27ec22d11 introduced a new instance of
QemuBootOrderLib, called QemuNewBootOrderLib. It is based on
UefiBootManagerLib, and rather than taking a complete BootOptionList as a
parameter, it expects that the "BootOrder" and "Boot####" variables are
complete in the above sense.
Rebase the boot order manipulation to UefiBootManagerLib and
QemuNewBootOrderLib, while keeping the requirement satisfied, like this:
BdsEntry() [MdeModulePkg/Universal/BdsDxe/BdsEntry.c]
PlatformBootManagerAfterConsole() [ArmVirtPkg/Library/PlatformBootManagerLib/PlatformBm.c]
EfiBootManagerConnectAll()
EfiBootManagerRefreshAllBootOption()
// at this point all auto-generated options exist at the end of
// "BootOrder"
SetBootOrderFromQemu() [OvmfPkg/Library/QemuNewBootOrderLib/QemuBootOrderLib.c]
// read boot options from "BootOrder" and "Boot####", then
// manipulate them
This patch parallels OvmfPkg commit 04fe914ba5.
Once the USE_OLD_BDS fallback is removed from OvmfPkg, the parameter list
of the SetBootOrderFromQemu() prototype can be updated to VOID.

"MdeModulePkg/Include/Library/PlatformBootManagerLib.h" declares the three
interfaces below:
- PlatformBootManagerBeforeConsole
- PlatformBootManagerAfterConsole
- PlatformBootManagerWaitCallback
Comparing the BdsEntry() functions between
- "IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c" and
- "MdeModulePkg/Universal/BdsDxe/BdsEntry.c",
we can establish the following mapping:
IntelFrameworkModulePkg MdeModulePkg
BdsEntry() BdsEntry()
PlatformBdsInit() <--------------> PlatformBootManagerBeforeConsole()
dispatch Driver#### <--------------> dispatch Driver####
connect consoles
PlatformBdsPolicyBehavior() <------> PlatformBootManagerAfterConsole()
The difference in connecting the consoles will be addressed in a later
patch, now we just rename the functions according to the mapping above,
and copy the call site comments from MdeModulePkg's BdsEntry().
For the third interface, PlatformBootManagerWaitCallback(), add an empty
implementation (and copy the comment from the library class header).
Platform BDS can use this callback to draw a progress bar, for example.
This patch parallels OvmfPkg commit a7566234e9.

Create a copy of PlatformIntelBdsLib under the name
PlatformBootManagerLib, with the following initial changes:
- replace PlatformBdsLib references with PlatformBootManagerLib in
comments,
- replace "IntelBdsPlatform" with "PlatformBm" in file names and their
references,
- generate a new FILE_GUID.
PlatformBootManagerLib will be linked into the BDS driver from
MdeModulePkg.
This patch parallels OvmfPkg commit 3054188189.

Now that we have moved the handling of the xen,xen DT node to XenioFdtDxe,
remove its handling from VirtFdtDxe. Since the only functionality that
remains is handling the virtio,mmio DT node, rename VirtFdtDxe to
VirtioFdtDxe to reflect that. Also update the platforms that use this
driver.

Now that the only functionality that remains in VirtFdtDxe is enumerating
the respective virtual I/O buses, it no longer makes sense to have a driver
that is shared between Xen domU and QEMU. So move the Xen I/O DT node
handling to a new driver, and update ArmVirtXen to switch to it.

Now that FdtClientDxe is the core driver that takes ownership of the host
supplied FDT, it makes sense to put it in charge of installing the FDT
configuration table as well.

We no longer care when VirtFdtDxe executes, since
- the driver sets no dynamic PCDs any longer, and
- the only remaining functionality centers on VirtioMmioInstallDevice()
and XenIoMmioInstall() function calls and FDT configuration table
installation.
So drop the A PRIORI declaration.

This moves QEMU based platforms to ArmVirtPL031FdtClientLib, so that we no
longer have to rely on VirtFdtDxe to execute first and set the PL031 base
address in a dynamic PCD.
The only driver which [transitively] depends on this PcdPL031RtcBase PCD is
EmbeddedPkg/RealTimeClockRuntimeDxe, so this conversion cannot affect any
other users and is thus safe.

This implements a library ArmVirtPL031FdtClientLib which is intended to
be incorporated into RealTimeClockRuntimeDxe via NULL library class
resolution. This allows us to make RealTimeClockRuntimeDxe depend on the
FDT client protocol, and discover the PL031 base address from the device tree
directly rather than relying on VirtFdtDxe to set the dynamic PCDs.
The NULL library class resolution approach to strictly order production and
consumption of dynamic PCDs is not generally safe in cases such as this one,
where the producer and the consumer of the PCD are both libraries. However,
since the PCD is produced in this library's constructor, and the consumer
library's constructor 'LibRtcInitialize' is not a 'true' constructor (it is
invoked explicitly by RealTimeClockRuntimeDxe), this case is guaranteed to
be safe after all.
