Ard Biesheuvel ffced38546 ArmVirtPkg: move TimerDxe to FDT client library
Move to the new dedicated ArmVirtTimerFdtClientLib to populate the
various timer related PCDs at driver load time rather than relying on
VirtFdtDxe to do it. Since ArmPkg/TimerDxe is the only consumer of these
PCDs, which is the DXE driver ArmVirtTimerFdtClientLib is intended to
complement, this conversion is guaranteed to be safe.

Ard Biesheuvel ea62bb766f ArmVirtPkg: implement ArmVirtTimerFdtClientLib
This implements a library ArmVirtTimerFdtClientLib which is intended to
be incorporated into TimerDxe via NULL library class resolution. This
allows us to make TimerDxe depend on the FDT client protocol, and
discover the timer interrupts from the device tree directly rather than
relying on VirtFdtDxe to set the dynamic PCDs.

Instead of relying on VirtFdtDxe to detect the PSCI method, move our
EfiResetSystemLib to the FDT client protocol to interrogate the device

Since this library is only consumed by EmbeddedPkg/ResetRuntimeDxe, and

Ard Biesheuvel 2248631883 ArmVirtPkg/ArmGicArchLib: move to FdtClient protocol
Instead of relying on VirtFdtDxe to populate the GIC related PCDs, move
this handling to our implementation of ArmGicArchLib, and retrieve the
required DT info using the new FDT client protocol.

This removes one of the reasons we need to load VirtFdtDxe first using
an 'A PRIORI' declaration in the platform FDF.

As Laszlo kindly confirms:

  So, ultimately, the only user of this library instance is
  "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". ... Indeed, checking the build
  report file for ArmVirtQemu (AARCH64), I find ArmVirtGicArchLib (and
  ArmGicLib too) only under "ArmPkg/Drivers/ArmGic/ArmGicDxe.inf".

which means that the constructor is only invoked once, and so the dynamic
PCDs are set in time for ArmGicDxe to consume them, and never afterwards.

Laszlo Ersek 6a238fa88f ArmVirtPkg: disable PcdHiiOsRuntimeSupport
Edk2 commit 8a45f80eda ("MdeModulePkg: Make HII configuration settings
available to OS runtime") implements the optional UEFI feature described
in "31.2.11.1 OS Runtime Utilization" in UEFI v2.6.

While this feature might show benefits down the road even in QEMU virtual
machines, at the moment it only presents drawbacks:
- it increases the EfiRuntimeServicesData footprint,
- it triggers HII compatibility problems between edk2 and external drivers
  unconditionally, even if the end-user is not interested in HII and/or in
  configuring said drivers (see
  <https://www.redhat.com/archives/vfio-users/2016-March/msg00153.html>
  and <http://thread.gmane.org/gmane.comp.bios.edk2.devel/9894> for an
  example).

While the feature was being introduced, popular demand for a controlling
Feature PCD rose (see
<http://thread.gmane.org/gmane.comp.bios.edk2.devel/7626>), which is why
we can set it now to FALSE.

Ard Biesheuvel b359fb9115 ArmVirtPkg/ArmVirtQemu: gate FDT config table install with build option
This introduces the .DSC define 'PURE_ACPI_BOOT_ENABLE', defaulting to
FALSE, which controls the value of the feature PCD 'PcdPureAcpiBoot'.

This allows an ArmVirtQemu image to be built that restricts the OS to
booting in ACPI mode.

This feature is only added to ArmVirtQemu, and not to ArmVirtQemuKernel,
the reason being that the latter is mostly intended for development work,
where the burden of adding 'acpi=force' if you need it is much more
tolerable than when trying to boot an installer on a production KVM guest
instance.

Ard Biesheuvel 8b816c624d ArmVirtPkg/VirtFdtDxe: set /chosen/linux,pci-probe-only to 1 in DTB
Unlike Linux on x86, which typically honors the PCI configuration performed
by the firmware, Linux on ARM assumes that the PCI subsystem needs to be
configured from scratch. This is not entirely unreasonable given the
historical background of embedded systems using very basic bootloaders,
but is no longer tenable with Linux on arm64 moving to UEFI and ACPI in the
server space. For this reason, PCI support in the arm64 kernel running under
ACPI is likely to move to the x86 model of honoring the PCI configuration
done by the firmware.

So let's align with that in our DT based configuration as well, and set the
/chosen/linux,pci-probe-only property to 1 in the Device Tree before we
hand it to the OS.

In case we are exposing an emulated VGA PCI device to the guest, which may
subsequently get exposed via the Graphics Output protocol and driven as an
efifb by the OS, this ensures the PCI resource allocations for the framebuffer
are not overridden, since that would cause the framebuffer to stop working.

Ard Biesheuvel ca6d61b226 ArmVirtPkg: ArmVirtQemu: expose only 64-bit entry point for v3.0+ SMBIOS
The legacy 32-bit SMBIOS entry point has little use on AARCH64 systems,
since many such systems have no 32-bit addressable physical RAM, and so
OSes that implement SMBIOS will have to be able to deal with the 64-bit
entry point anyway.

Given that the OS will map main memory in 1 GB chunks if it can, and that
punching a page sized hole (e.g., for SMBIOS data) into it will result in
the whole 1 GB chunk being mapped using 2 MB and 4 KB blocks instead, it
is important to group memory reservations from the OS as much as we can,
and allocating below 4 GB for no good reason interferes with that.

This is especially important under virtualization, considering that each
*level* of lookup at stage 1 (the guest virtual page table) will result in
a full page table walk at stage 2 (the guest PA to host PA mapping).

So expose only the 64-bit entry point when the SMBIOS tables adhere to
version 3.0 or later.

Star Zeng ad7f6bc2e1 ArmVirtPkg: Use SerialDxe in MdeModulePkg instead of EmbeddedPkg
Beyond just changing the directly related lines in the FDF and DSC files,
we have to adapt the EarlyFdtPL011SerialPortLib and FdtPL011SerialPortLib
instances as well, in the same patch. This is because the EmbeddedPkg
driver expects the SerialPortSetAttributes(),
SerialPortSetControl() and SerialPortGetControl() functions from
SerialPortExtLib, while the MdeModulePkg driver expects them from
SerialPortLib itself.

We cannot implement these functions in ArmVirtPkg's SerialPortLib
instances *before* flipping the driver, because it would cause double
function definitions in the EmbeddedPkg driver. We also can't implement
the functions *after* flipping the driver, because it would cause
unresolved function references in the MdeModulePkg driver. Therefore
we have to implement the functions simultaneously with the driver
replacement.

Ard Biesheuvel 1dc3f34f61 ArmVirtPkg/ArmVirtPlatformLib: reduce ID map size to GCD region size
The ID mapping routines on virtual platforms simply map the entire
hardware supported physical address space as device memory, and then
punch some holes for regions that need to be mapped cacheable.
On virtual platforms hosted on CPUs that support a large physical
address range, this may result in a lot of overhead, i.e., 4 KB of page
tables for each 512 GB of address space, which quickly adds up (i.e.,
2 MB for the architectural maximum of 48 bits).

Since there may be a platform specific limit to the size of the (I)PA
space that is not reflected by CPU id registers, restrict the range of
the ID mapping to gEmbeddedTokenSpaceGuid.PcdPrePiCpuMemorySize bits.
This makes sense by itself, since we cannot manipulate mappings above
that limit anwyay (because they are not covered by GCD), and it allows
the PCD be set to a lower value by platforms whose (I)PA space is
smaller than the hardware supported maximum.

Ard Biesheuvel dca7f96fd2 ArmVirtPkg/ArmVirtPlatformLib: map executable NOR region as normal memory
The ARM architecture version 7 and later mandates that device mappings
have the XN (non-executable) bit set, to prevent speculative instruction
fetches from read-sensitive regions. This implies that we should not map
regions as device if we want to execute from them, so the NOR region that
contains our FD image should be mapped as normal memory instead.

The MMU code deals correctly with overlapping ARM_MEMORY_REGION_DESCRIPTOR
entries, and later entries in the array take precedence over earlier ones.
So simply add an entry to the end of the array that overrides the mapping
attributes of the FD image, wherever it resides.

Ard Biesheuvel 2f71ad11d6 ArmVirtPkg: reduce preallocation of boot services data pages
Commit SVN r18503 ("MdeModulePkg DxeCore: Take the range in resource
HOB for PHIT as higher priority") changed the GCD init logic to take
the sum of the region sizes in gMemoryTypeInformation[] into account
when estimating the minimal amount of memory needed to boot the system.

Unfortunately, as an unintended side effect, this change results in boot
failures of ArmVirtQemu when running with QEMU's default memory size of
128 MB. The reason is that the sum of the gMemoryTypeInformation region
sizes plus the size of the inital PEI region exceeds 128 MB. Since we do
not actually need to preallocate 20,000 pages' worth of BootServicesData
memory, reduce this figure to the more reasonable 12,000.

  variable reclaim and (optionally) installs variable usage statistics as

- OnReadyToBoot() in

Laszlo Ersek 34eeb6763b ArmVirtPkg: set SMBIOS version in DetectSmbiosVersionLib instead of QemuFwCfgToPcdDxe

  ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version

(git c98da334, SVN r18043) by hooking DetectSmbiosVersionLib into
SmbiosDxe.

Although said commit was supposed to work with SMBIOS 3.0 payloads from
QEMU, in practice that never worked, because the size / signature checks
in SmbiosVersionInitialization() would always fail, due to the SMBIOS 3.0
entry point being structurally different. Therefore this patch doesn't

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

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.

Laszlo Ersek c98da3345a ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version dynamically
(This patch parallels OvmfPkg commit 37baf06b (SVN r17676).)

PcdSmbiosVersion controls the version number of the SMBIOS entry point
table (and other, related things) that the universal
"MdeModulePkg/Universal/SmbiosDxe" driver, providing EFI_SMBIOS_PROTOCOL,
installs.

The "virt" machine type of QEMU generates 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.

As default for PcdSmbiosVersion we should keep the current 0x0300 value
(ie. SMBIOS 3.0) from "MdeModulePkg/MdeModulePkg.dec"; that spec version
was specifically created for ARM / AARCH64 needs.

Laszlo Ersek d2733aa95a ArmVirtPkg: add QemuFwCfgToPcdDxe
Many universal DXE drivers in edk2 can be controlled by setting dynamic
PCDs. Such a PCD must be set before the consumer DXE driver is dispatched.

(In general we assume that the DXE driver will consume the PCD in its
entry point, or in the constructor of a library instance it links against.
In special cases this requirement can be relaxed a bit, if we know that
the DXE driver accesses the PCD only in a protocol member function that it
exports.)

On the QEMU platform, the PCD values to be set for the universal drivers
are frequently derived from fw_cfg files that QEMU exports.

In OvmfPkg we tend to handle this in the following way:

- For IA32 and X64, OvmfPkg provides a QemuFwCfgLib instance that is
  usable in PEI.

- In PlatformPei, fw_cfg files can be loaded and transformed to PCD
  values.

- Any DXE driver is bound to be dispatched after the PEI phase is done.

(In specific cases other ordering solutions might be possible, via Depex
or protocol notify, etc.)

In ArmVirtPkg/ArmVirtQemu, things differ a bit:

- We don't have an ArmVirtPkg-specific ("Platform") PEIM. This is actually
  a good thing for now, so let's not introduce one just for this purpose.

- Even if we had such a PEIM, it could not easily access fw_cfg: the MMIO
  addresses of the fw_cfg device are available only in the DTB that QEMU
  exports.

  (Accordingly, our QemuFwCfgLib instance is restricted to DXE_DRIVER
  modules: VirtFdtDxe parses the DTB, stores the fw_cfg addresses in PCDs,
  and then QemuFwCfgLib's constructor fetches those PCDs.)

  There are some examples in ArmVirtPkg where early code is forced to
  parse the DTB manually, but those examples are all painful, and our goal
  here (controlling universal DXE drivers) doesn't justify more of that
  pain.

Therefore, introduce a separate, minimal DXE driver that is dispatched
strictly after VirtFdtDxe (so that it can use QemuFwCfgLib), and strictly
before other DXE drivers (so that it can set dynamic PCDs for them).
Because VirtFdtDxe is already ordered with the APRIORI DXE file, it is
simplest to do the same for the new driver.

Actual fw_cfg files and PCDs shall be accessed in future patches.

Change default terminal type to be consistent with default
ConIn/ConOut device path, which is now determined by TTY_TERMINAL
flag, TTYTERM or VT100.

I can't say this is a bug, as we can pass the whole console device
path to ConnectController, and TerminalDxe driver will pick up the
terminal in the remaining device path. However, in rare circumstances,
the console devices may be disconnected with the driver, and they will
be ignored by ConPlatformDxe until we pass the device path explicitly
just as BDS.

Changing default terminal type to be the same with console device
path could help serial terminal be reconnected with normal connect
controller operation.

Ard Biesheuvel 226d10c357 ArmVirtPkg: build runtime drivers with 64 KB section alignment
This adds the 64 KB alignment overlay linker script to the linker
command line of DXE_RUNTIME_DRIVER modules. This makes these modules
compatible with the new Properties Table feature by aligning the .text
and .data sections to 64 KB.

BaseCryptLib has been declared at [LibraryClasses.common.DXE_RUNTIME_DRIVER]

Ard Biesheuvel 9cd7d3c5ba ArmVirtPkg: signal EndOxDxe event in PlatformBsdInit
Currently, the ArmVirtPkg 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 ArmVirtPkg's
PlatformBdsLib implementation for the Intel BDS.

Ard Biesheuvel e0bb8ad944 ArmVirtPkg: increase memory preallocations for secure build
This is a followup to r17554 ("ArmVirtPkg: increase memory
preallocations to reduce region count") that increases the sizes
of the preallocated regions to account for the footprint of the
crypto and authentication libraries. This is only done if secure
boot is enabled at build time, to prevent imposing a larger minimum
RAM size on non-secure builds.

Both files originate from ArmPlatformPkg.

The copyright notices at the top of "License.txt" have been refreshed as
follows:
- I grepped ArmVirtPkg for "copyright", case-insensitively
- for each copyright holder company, I unified the intervals to the
  strictest superset (no absent year was introduced in this process)
- I listed the copyright notices in decreasing order of last contribution
  year.
- When a "last contribution year" was shared by several notices, I sorted
  those between each other in descending "first contribution year" order.

Ard Biesheuvel c1993157bd ArmVirtPkg: increase memory preallocations to reduce region count
This updates the sizes of the preallocated regions so that the number
of distinct regions that exists is minimal at the time we exit boot
services.

For a typical run of the ArmVirtQemu platform, we get the following
utilization numbers:

  Reserved  :              4 Pages (16,384 Bytes)
  LoaderCode:            210 Pages (860,160 Bytes)
  LoaderData:              0 Pages (0 Bytes)
  BS_Code   :            355 Pages (1,454,080 Bytes)
  BS_Data   :          6,807 Pages (27,881,472 Bytes)
  RT_Code   :            112 Pages (458,752 Bytes)
  RT_Data   :            288 Pages (1,179,648 Bytes)
  ACPI_Recl :             32 Pages (131,072 Bytes)
  ACPI_NVS  :              0 Pages (0 Bytes)
  MMIO      :         16,385 Pages (67,112,960 Bytes)
  MMIO_Port :              0 Pages (0 Bytes)
  PalCode   :              0 Pages (0 Bytes)
  Available :        123,264 Pages (504,889,344 Bytes)
              --------------
Total Memory:            511 MB (536,854,528 Bytes)

Strangely enough, the allocation count of 20,000 pages for BS_Data
does not result in those regions being merged. For BS_Code, RT_Code
and RT_Data, the increased preallocation results in the following
reduction in the number of regions.
