Juno has several serial ports, one of which may be used for a remote
debug interface (e.g. gdb, WinDbg). The debug serial port needs to
be distinct from that used for UEFI trace to prevent corruption of
debugger protocol messaging.
The UEFI spec requires that serial devices be initialised to default
settings. (11.8 Serial I/O Protocol - "The default attributes for all
UART-style serial device interfaces are: 115,200 baud, ..."
and 17.3.3 EFI Debugport Variable - "These defaults must be used in the
absence of a DEBUGPORT variable...")
This change adds initialization of the serial device reported in the
ACPI DBG2 table. The initialisation is done early in the boot to allow
the possibility of remote debug of UEFI itself.
NOTE: This is functionally dependent on the DBG2 table being updated in
OpenPlatformPkg, but is required as a precursor to that change.

Now that the generic Variable Runtime DXE code no longer distinguishes
between gEfiVariableGuid and gEfiAuthenticatedVariableGuid in the varstore
FV header, we can relax the check in the NOR flash driver to accept either
GUID regardless of whether we are running a secure boot capable build or not.
This also means we can always use gEfiAuthenticatedVariableGuid when we
encounter an empty NOR flash that needs to be initialized before use. So
remove the mNorFlashVariableGuid global from the shared code and from both
versions of NorFlashDxe.inf. This essentially collapses the two drivers into
a single one, which means we can remove NorFlashAuthenticatedDxe entirely

This change corrects 3 problems in the PL011 driver.
1. The TRM states "The UARTLCR_H, UARTIBRD, and UARTFBRD registers must
not be changed:...when the UART is enabled"
2. The TRM (3.3.8) describes logic requiring the UART to be disabled and
flushed before adjusting UARTCR.
3. Several redundant calls get made to PL011UartInitializePort, where
the characteristics do not change, but updating the registers can
cause glitches in the output stream.
The parameters are compared to the current state and no action taken if
no change of state is required.
Where an update is required, the specified logic is followed, and the
register updates only made when the UART is disabled.

On some platforms the UART clock is not the same for all the serial

different clock rates, so must not rely on a PCD for the clock rate.
This patch allows the UART clock rate to be passed as a parameter
to PL011UartInitializePort(), which is called from the serial port
library. This patch also contains the corresponding changes in the
serial port library.
The PCD in Drivers/PL011Uart is replaced by an extra parameter for
PL011UartInitializePort. The PCD is moved to Library/PL011SerialPortLib
to supply the value to pass.

aligns temporary heap size and temporary stack size, but does not do
the same thing when switching stack and heap to permanent memory, and
then it may cause fatal data corruption like PHIT HOB lost and stack

We currently rely on .align directives to ensure that each exception
vector entry is the appropriate offset from the vector base address.
This is slightly fragile, as were an entry to become too large (greater
than 32 A64 instructions), all following entries would be silently
shifted until they meet the next alignment boundary. Thus we might
execute the wrong code in response to an exception.
To prevent this, introduce a new macro, VECTOR_ENTRY, that uses .org
directives to position each entry at the precise required offset from
the base of a vector. A vector entry which is too large will trigger a
build failure rather than a runtime failure which is difficult to debug.
For consistency, the base and end of each vector is similarly annotated,
with VECTOR_BASE and VECTOR_END, which provide the necessary alignment
and symbol exports. The now redundant directives and labels are removed.

Some users of this library (i.e., FVP-AArch64 and RTSM-A15_MPCore)
may be built to execute straight from NOR flash. Since device mappings
should have the XN attribute set (according to the architecture), mapping
the NOR flash as a device may prevent it from being executable.
Since the NOR flash DXE driver is perfectly capable of setting the correct
attributes for the region it needs to write to, and since we will be
executing from DRAM by that time anyway, we can simply map the NOR flash
as normal memory initially.

These patches correct a number of problems with the JUNO ACPI tables.
First, put CCA attributes on the devices which can do DMA. This is
because the linux kernel now requires ARM64 devices specify a coherency
model. Without CCA the devices are unable to perform DMA.
Update the EHCI window to a full 64k as documented in the
Juno Platform SoC TRM. This makes it match the values used in some
other places.
Finally, add some _DSD entries for the SMSC ethernet chip.
The latter changes are required for the mainline kernels to use the adapter.

The ValidateFvHeader() function checks several conditions against the
firmware volume header. Failure of the first of these checks, reported as
"No Firmware Volume header present", is a common situation for unformatted
flash images, especially when a new virtual machine is created.
Similarly, "Variable Store Guid non-compatible" is common when the
firmware binary is switched from Secure Boot-incapable to Secure
Boot-capable, or vice versa.
The only caller of ValidateFvHeader(), NorFlashFvbInitialize(), handles
all these mismatches by installing a new FVB header. It also emits
another, loud ERROR message (which is even less justified when it is
triggered by (BootMode == BOOT_WITH_DEFAULT_SETTINGS)).
Downgrade these messages from EFI_D_ERROR to EFI_D_INFO, so that they
don't clutter the debug output when the PcdDebugPrintErrorLevel mask only
enables EFI_D_ERROR (i.e., in a "silent" build).
These messages have annoyed / confused users; see for example:

Like the ArmVirtPkg platforms up until SVN r17713, the ArmPlatformPkg
platforms built with the Intel BDS fail to signal the end-of-DXE event
'gEfiEndOfDxeEventGroupGuid' when entering the BDS phase, which results
in some loss of functionality, i.e., variable reclaim in the VariableDxe
drivers, and the splitting of the memory regions that is part of the recently
added UEFI 2.5 properties table feature.
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 that event, 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.
So add the SignalEvent () call to PlatformBdsInit () of ArmPlatformPkg's
PlatformBdsLib implementation for the Intel BDS.

Now that GenFw correctly propagates the minimum alignment of the ELF
input sections to the PE/COFF binary, we can simply select 'auto'
alignment in the FDF Rule section instead of tweaking it by hand.
Also add the FIXED FFS attribute to the module types that may execute
in place. This enables a newly added optimization in GenFfs that strips
redundant padding, preventing excessive waste of FV space if the section
alignment is considerable (i.e., 2 KB or 4 KB)

The ACPI .aslc files contain a ReferenceAcpiTable() function whose
sole purpose is to ensure that the table itself does not get optimized
away. However, when using clang, these dummy functions result in a 4 KB
section alignment requirement, which is silly since everything except
the .data section is discarded later anyway.
So instead, make ReferenceAcpiTable a CONST pointer to VOID*. This way,
we still have a .text section, which is mandatory for the PE/COFF
conversion, but no executable code with small model relocations that
impose additional alignment requirements.

Since PrePeiCore's .text section contains an AARCH64 exception
vector table, its 2 KB alignment propagates to other sections as
well. Since this is a SEC module, it should not have any writable

The current implementation of ArmGicGetSupportedArchRevision ()
that is used by all ARM platforms is entirely stateless (in order
to support being executed from flash) so it needs to interrogate
the hardware for the supported GIC revision upon each invocation.
However, this statelessness is only needed for SEC type modules;
in all other cases, we could easily determine the GIC revision once,
and store the result in a global variable.
In preparation of having separate early and normal versions, this patch
introduces the ArmGicArchLib library class and default implementation,
and moves the existing ArmGicGetSupportedArchRevision () into it.

Note: The reason why the start of the System Memory has not been

The NorFlashDxe uses an explicit 'BEFORE xxx' Depex declaration to
ensure that it is dispatched before VariableRuntimeDxe, and uses the
file GUID of the latter as 'xxx' explicitly to accomplish that.
However, when enabling UEFI Secure Boot, this breaks down since the
authenticated VariableRuntimeDxe is a completely separate driver, with
a different GUID. Also, the hardcoded dependency on gEfiVariableGuid,
which is not used under UEFI Secure Boot, needs to be factored out in
order to allow this driver to be used.
So clone NorFlashDxe.inf into NorFlashAuthenticatedDxe.inf, and fix
up the dependencies so they refer to gEfiAuthenticatedVariableGuid and
SecurityPkg/VariableAuthenticated/RuntimeDxe/VariableRuntimeDxe.inf
instead.

In order to prevent memory corruption issues caused by the fact that,
under virtualization, the guest is incoherent with the hypervisor's view
of memory until it enables its caches and MMU, this patch reshuffles the
init sequence so that the Xen shared memory regions are not touched
before the caches and MMU are enabled.
In addition, the loaded image itself is invalidated by virtual address,
to ensure that any runtime changes (such as the applied relocations) will
not suddenly become invisible once we turn the caches on.

shadowing NOR flash with system RAM). This is never the case for the
Qemu target, which is the only platform affected by this change, since
the Xen target already uses this library explicitly.
This allows us to remove the Xen-specific declaration of this library
dependency. For the Qemu target, this change will not take effect until
after the MemoryInitPeim<->MemoryInitPeiLib dependency resolution is
fixed in a subsequent patch.

The "virt" machine type of qemu-system-(arm|aarch64) had no PCIe support
prior to qemu commit
4ab29b82 arm: Add PCIe host bridge in virt machine
With that commit, the "virt" board acquired the capability to expose an
XHCI controller. Using a USB keyboard as example, the command line options
were
-device nec-usb-xhci -device usb-kbd
However, due to a slight XHCI emulation bug in QEMU -- dating back to
several years earlier -- edk2's XHCI driver would encounter a failed
ASSERT().
This emulation problem has been fixed in QEMU commit
aa685789 xhci: generate a Transfer Event for each Transfer TRB with the
IOC bit set
and now edk2's XHCI driver works well on QEMU's "nec-usb-xhci" device.
Let's enable the driver in ArmVirtualizationQemu, as XHCI emulation is
reportedly more virtualization-friendly than EHCI, consuming less CPU.
(ArmVirtualizationXen is not modified because it includes no USB-related
drivers at all.)
This patch should not regress existing QEMU command lines (ie. expose the
failed ASSERT()) because QEMU's "-device nec-usb-xhci" has never before
resulted in USB devices that worked with edk2 firmware builds, hence users
have never had a reason to add that option.
Now that they learn about XHCI support in ArmVirtualizationQemu by reading
this commit message, they (or their packagers) will also know to update
qemu to aa685789 or later (in practice that means the upcoming 2.3
release), at least if they want to use '-device nec-usb-xhci' with edk2,
for the first time ever.

Including a prebuilt shell executable in the firmware binary is suboptimal
practice, especially given that the source code of the UEFI shell resides
in the same edk2 tree. Benefits of building the shell from source are
partly technical (a developer patching the shell can actually see the
results), partly ideological (the nominally built-from-source firmware is
actually built from source). "Security" might be worth a mention too.

When the user doesn't pass a kernel with QEMU's "-kernel" switch, the
firmware sees a zero-sized kernel blob via the QemuFwCfgItemKernelSize
key; there's no way to distinguish "no kernel" from "zero sized kernel".
In both cases TryRunningQemuKernel() proceeds as far as gBS->LoadImage(),
which then rejects the zero sized synthetic file with EFI_UNSUPPORTED.
This is known and works fully as expected; however we should rather catch
the much more frequent "no kernel" case earlier, in order to avoid the
EFI_D_ERROR message
TryRunningQemuKernel: LoadImage(): Unsupported
which is arguably meaningless noise for the "no kernel" case.

This implements a MemoryInitPeiLib instance that differs from the
stock ArmPlatformPkg version only in the fact that it does not remove
the memory used by the flash device (FD). The reason is that, when using
PrePi, the DXE core is started immediately and never returns so there is
no reason to preserve any of the memory that the flash device occupied
originally, and it is preferable to release is so that the OS loader
can reuse it. This is especially important for the relocatable PrePi
configuration, which is aimed at being launched from a boot loader that
itself adheres to the Linux arm64 boot protocol.

In this patch we remove all dependencies on ARM BDS libraries. We also
remove empty and/or unneeded functions, includes, etc.
PlatformIntelBdsLib "goes back to basics" temporarily -- there are no
consoles configured, and it's practically not possible to interact with
the user interface. Bisection remains available in the sense that
"ArmVirtualizationQemu.dsc" continues to build and should boot preexistent
boot options, but user interaction does regress temporarily.
The reason for this is that it's preferable to keep this patch and the
next one separate for readability's sake -- they amount to a rewrite from
scratch.

In the following call chain:
PlatformBdsPolicyBehavior()
PlatformBdsConnectConsole()
InitializeConsolePipe() x 3
BdsConnectDevicePath() [ArmPkg/Library/BdsLib/BdsFilePath.c]
the three InitializeConsolePipe() function calls pass through
- (&gST->ConsoleOutHandle, &gST->ConOut),
- (&gST->ConsoleInHandle, &gST->ConIn),
- (&gST->StandardErrorHandle, &gST->StdErr)
to BdsConnectDevicePath(), in ArmPkg's BdsLib.
At least when more than one console device paths are specified in the
ConIn / ConOut / ErrOut variables, the above resuls in:
- unchanged protocol interfaces (ConOut, ConIn, StdErr) in the system
table (because ConSplitterDxe installs its non-NULL interfaces first),
- but, changed handles in the system table.
This effectively separates the handle fields in the system table from the
protocol interfaces in the same that should always be associated with the
handles. The end result is that clients using the handles break (splitting
/ multiplexing doesn't work for them), while clients directly using the
protocol interfaces work.
Therefore, do not attempt to connect consoles separately. ConSplitterDxe
is dispatched before PlatformBdsPolicyBehavior() is called (the latter
happens in the BDS phase), and ConSplitterDxe installs virtual handles and
protocol interfaces for input / output / error.
BdsLibConnectAll() covers all devices, including consoles; as those
consoles are connected, ConPlatformDxe and ConSplitterDxe pick them up
nicely as "slaves". We just need to make sure that the variables are set
first, for the variables -> ConPlatformDxe -> ConSplitterDxe dependency
chain.

It is considered an error if no resource requests are submitted for a
PCI root bridge. If a PCI root bridge does not require any resources, a
zero-length resource request must explicitly be submitted.

If ConstructAcpiResourceRequestor() finds no resources to request (for
example because no PCI devices are on the root bridge), it places a
zero-length EFI_ACPI_ADDRESS_SPACE_DESCRIPTOR followed by an
EFI_ACPI_END_TAG_DESCRIPTOR in "AcpiConfig"; satisfying the PI spec.
However, PciHostBridgeDxe's SubmitResources() function does not expect
such input; the following part of the code rejects it:
switch (Ptr->ResType) {
case 0:
//
// Check invalid Address Sapce Granularity

In the EfiPciHostBridgeAllocateResources phase, we allocate memory BARs
bottom up, from whichever MMIO range comes first and has room left.
Unfortunately, this places memory BARs into MMIO ranges that belong to
other devices. (Arguably, their respective drivers should not just add,
but immediately allocate those ranges as well.)
(
This problem is not seen in OVMF / PcAtChipsetPkg, because there we
allocate bottom-up from the range
[max(2GB, top-of-low-RAM), 0xFC000000).
(See the MMIO resource descriptor HOB created in MemMapInitialization()
[OvmfPkg/PlatformPei/Platform.c].)
That MMIO range fits in the static [2GB, 4GB) aperture given in
"mResAperture" in PcAtChipsetPkg/PciHostBridgeDxe; plus other MMIO
ranges (IO-APIC, HPET, LAPIC, flash chip) are higher than 0xFC000000.
Hence the bottom-up BAR allocation in OvmfPkg always finds the right
MMIO range first.

In ArmVirtualizationPkg/PciHostBridgeDxe we can solve the problem by
working our way downwards from the top of our own aperture.

Because the IO aperture is based at zero, the first allocation happens to
get the zero address. However, a zero address for a PCI BAR is considered
unmapped; see eg.:
- <http://www.pcisig.com/reflector/msg00459.html>,
- the (new_addr == 0) part in QEMU, pci_bar_address() [hw/pci/pci.c]:
new_addr = pci_get_long(d->config + bar) & ~(size - 1);
last_addr = new_addr + size - 1;
/* Check if 32 bit BAR wraps around explicitly.
* TODO: make priorities correct and remove this work around.
*/
if (last_addr <= new_addr || new_addr == 0 || last_addr >= UINT32_MAX)
{
return PCI_BAR_UNMAPPED;
}
We can avoid this problem by allocating top-down in the IO aperture.

Quite non-intuitively, we must allow guest-side writes to emulated PCI
MMIO regions to go through the CPU cache, otherwise QEMU, whose accesses
always go through the cache, may see stale data in the region.
This change makes no difference for QEMU/TCG, but it is important for
QEMU/KVM, at the moment.

VirtFdtDxe parses the following address space properties from the DTB (and
saves them in PCDs) :
ProcessPciHost: Config[0x3F000000+0x1000000)
Bus[0x0..0xF]
Io[0x0+0x10000)@0x3EFF0000
Mem[0x10000000+0x2EFF0000)@0x0
In order to allow PCI enumeration to allocate IO and MMIO resources from
the above ranges for devices, we must add the ranges to the Global
Coherency Domain.
There are two ways for that:
- building resource descriptor HOBs in the HOB producer phase (basically,
PEI), and letting the DXE core process them,
- calling gDS->AddIoSpace() and gDS->AddMemorySpace() during DXE.
We opt for the second method for simplicity.
In the address space maps, the corresponding ranges change from
"nonexistent" to "IO" and "MMIO", from which the gDS->AllocateIoSpace()
and gDS->AllocateMemorySpace() services can later allocate PCI BARs.

Roughly, there are two ways to "measure ticks" in UEFI:
- the SetTimer() boot service, which sets up a one-shot or periodic event
callback, and takes the interval length in units of 100ns,
- the Stall() boot service, which stalls the caller (but does not yield
the CPU) for the interval specified. The interval is taken as a number
of microseconds.
If the platform in question also follows the PI (Platform Init)
specification, then it is recommended to implement the above UEFI services
on top of the following DXE Architectural Protocols (described in PI
Volume 2):
- Timer Architectural Protocol:
"Used to set up a periodic timer interrupt using a platform specific
timer, and a processor-specific interrupt vector. This protocol enables
the use of the SetTimer() Boot Service. [...]"
- Metronome Architectural Protocol:
"Used to wait for ticks from a known time source in a platform. This
protocol may be used to implement a simple version of the Stall() Boot
Service. [...]"
Edk2 in general, and ArmVirtualizationQemu in particular, follow the above
pattern.
SetTimer() works correctly. The underlying Timer Architectural Protocol is
provided by "ArmPkg/Drivers/TimerDxe", and that driver calls the internal
function ArmGenericTimerGetTimerFreq() to retrieve the timer frequency.
Ultimately it boils down to reading the CNTFRQ_EL0 register.
The correct behavior of SetTimer() can be observed for example:
- in the grub-efi countdown ("grub-core/kern/arm/efi/init.c"),
- in the Intel BDS front page countdown
("IntelFrameworkModulePkg/Universal/BdsDxe/FrontPage.c").
However, Stall() doesn't work correctly. The underlying Metronome
Architectural Protocol is provided by "EmbeddedPkg/MetronomeDxe", which
further delegates the job to the TimerLib library class. That in turn is
resolved to the "ArmPkg/Library/ArmArchTimerLib" instance, which
(finally!) takes the timer frequency from "PcdArmArchTimerFreqInHz".
In ArmVirtualizationQemu we currently specify 100MHz for this PCD. Alas,
that's incorect for:
- both QEMU/TCG (which emulates 62.5MHz, see GTIMER_SCALE in
"target-arm/internals.h"),
- and KVM (where the host's virtualized timer can tick at 50 MHz, for
example).
Set the PCD to 0, asking ArmArchTimerLib to interrogate CNTFRQ_EL0 as
well.
The change can be tested with eg. the following callers of Stall():
- the UEFI Shell's countdown -- before it runs "startup.nsh" -- relies on
Stall(),
- the UEFI shell command "stall" also uses Stall(). (Time it with a
stopwatch.)
