Andrew Fish 1a670f639b ShellPkg: Fix bad TimeZone (TZ) conversion.
EFI_UNSPECIFIED_TIMEZONE means display local time. TZ of 0 is UTC.
Thus EFI_UNSPECIFIED_TIMEZONE means ignore TZ, 0 means UTC. When this code is
fixed to adust file TZ to local TZ you need to preserve
EFI_UNSPECIFIED_TIMEZONE.

FAT always return EFI_UNSPECIFIED_TIMEZONE.

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.

Laszlo Ersek 164cf40383 OvmfPkg: SmbiosPlatformDxe: restrict current Xen code to IA32/X64
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.

Laszlo Ersek 9d7051b7a0 OvmfPkg: install DxeSmmReadyToLock in PlatformBdsLib
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.

Ard Biesheuvel 155f9d424c IntelFrameworkModulePkg/GenericBdsLib: remove AcpiS3->S3Save() call
The AcpiS3->S3Save() call needs to occur before the end-of-DXE event
is signalled. The end-of-DXE event needs to be signalled prior to
invoking any UEFI drivers, applications, or connecting consoles.

This means the call to S3Save() that occurs in BdsLibBootViaBootOption()
violates the ordering constraints, and should be removed. Since it is
the responsibility of the platform BDS to signal the end-of-DXE event,
it should also perform the AcpiS3->S3Save() call at an appropriate time.

Commit message update from Laszlo Ersek <lersek@redhat.com>:

Following Jiewen Yao's idea in

 http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16146

platforms that
(1) use this exact instance of GenericBdsLib, *and*
(2) support S3

should now collect the S3 state
(3) in an End-of-Dxe callback in their AcpiS3SaveDxe drivers, *or*
(4) with an explicit AcpiS3->S3Save() call made to their AcpiS3SaveDxe
    drivers from their PlatformBdsLib instances.

OvmfPkg, which uses this GenericBdsLib instance, and has its own
AcpiS3SaveDxe fork, follows (3).

Vlv2TbltDevicePkg, which has a GenericBdsLib fork, and uses
IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe, follows (4).

There are no other platforms in the public edk2 repository that support
S3.

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.

Laszlo Ersek b88ac532a6 OvmfPkg: AcpiS3SaveDxe: call S3Ready() at End-of-Dxe
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
driver is OvmfPkg. That platform does not signal End-of-Dxe (yet).)

Laszlo Ersek 421957fb38 OvmfPkg: AcpiS3SaveDxe: prepare for End-of-Dxe callback
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.

Star Zeng c03beb762a MdeModulePkg PiSmmCore: Remove a hidden assumption of SMRAM reservation
that assumes the SMRAM reserved range is only at the end of the SMRAM descriptor.

          //
          // This range has reserved area, calculate the left free size
          //
          gSmmCorePrivate->SmramRanges[Index].PhysicalSize = SmramResRegion->SmramReservedStart - gSmmCorePrivate->SmramRanges[Index].CpuStart;

Imagine the following scenario where we just reserve the first page of the SMRAM range:

SMRAM Descriptor:
  Start: 0x80000000
  Size: 0x02000000

Reserved Range:
  Start: 0x80000000
  Size: 0x00001000

In this case the adjustment to the SMRAM range size yields zero: ReservedStart - SMRAM Start is 0x80000000 - 0x80000000 = 0.
So even though most of the range is still free the IPL code decides its unusable.

The problem comes from the email thread: [edk2] PiSmmIpl SMRAM Reservation Logic.
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/15268

Also to follow the idea in the email thread, the patch is to
1. Keep only one copy of full SMRAM ranges in gSmmCorePrivate->SmramRanges,
split record for SmmConfiguration->SmramReservedRegions and SMM Core that
will be marked to be EFI_ALLOCATED in gSmmCorePrivate->SmramRanges.
2. Handle SmmConfiguration->SmramReservedRegions at beginning of, at end of,
in the middle of, or cross multiple SmramRanges.

Heyi Guo a5955fa352 ArmVirtPkg: Make terminal type consistent
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.
