Ard Biesheuvel c6d2972645 OvmfPkg: XenConsoleSerialPortLib: deal with output overflow
It is the responsibility of the SerialPortLib implementation
to deal with flow control if the underlying medium cannot keep
up with the inflow of data.

So in our SerialPortWrite () function, we should spin as long
as we need to in order to deliver all the data instead of giving
up and returning a smaller value than the number of bytes we were
given. Also, remove the 'if (Sent > 0)' condition on the signalling
of the event channel: if the buffer is full and we haven't been able
to add any more data, it makes perfect sense to signal the event
channel again, even if we have done so before when we did write
the data.

Also, this patch brings the implementation of XenSerialPortLib
in sync with the library class documentation.

[lersek@redhat.com: replace DebugLib dependency with open-coded ASSERT()]

Gabriel Somlo e2ab3f819f OvmfPkg: Q35: Use correct ACPI PM control register:bit
On PIIX4, function 3, the PMREGMISC register at offset 0x80, with
default value 0x00 has its bit 0 (PMIOSE) indicate whether the PM
IO space given in the PMBA register (offset 0x40) is enabled.
PMBA must be configured *before* setting this bit.

On Q35/ICH9+, function 0x1f, the equivalent role is fulfilled by
bit 7 (ACPI_EN) in the ACPI Control Register (ACPI_CNTL) at offset
0x44, also with a default value of 0x00.

Currently, OVMF hangs when Q35 reboots, because while PMBA is reset
by QEMU, the register at offset 0x80 (matching PMREGMISC on PIIX4)
is not reset, since it has a completely different meaning on LPC.
As such, the power management initialization logic in OVMF finds
the "PMIOSE" bit enabled after a reboot and decides to skip setting
PMBA. This causes the ACPI timer tick routine to read a constant
value from the wrong register, which in turn causes the ACPI delay
loop to hang indefinitely.

This patch modifies the Base[Rom]AcpiTimerLib constructors and the
PlatformPei ACPI PM init routines to use ACPI_CNTL:ACPI_EN instead
of PMREGMISC:PMIOSE when running on Q35.

Laszlo Ersek 47e57f4f5f OvmfPkg: include XHCI driver
QEMU commit aa685789 ("xhci: generate a Transfer Event for each Transfer
TRB with the IOC bit set") fixed an emulation problem in QEMU; we can now
drive that host controller with edk2's XhciDxe. Include it in OvmfPkg, as
XHCI emulation is reportedly more virtualization-friendly than EHCI,
consuming less CPU.

The driver can be tested with the following QEMU command line options:

  -device nec-usb-xhci -device usb-kbd

This patch should not regress existing QEMU command lines (ie. trigger an
ASSERT() in XhciDxe that fails on pre-aa685789 QEMU) 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 OVMF 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.

Laszlo Ersek 48b3ff0479 OvmfPkg: replace strict XenHypercallLib construction with explicit query
XenHypercallLib has two clients at the moment: XenBusDxe and
XenConsoleSerialPortLib. Currently, when XenBusDxe starts on a non-Xen X86
platform (ie. as part of OVMF not running on Xen), the X86XenHypercallLib
instance built into it fails to initialize, which triggers an ASSERT() in
auto-generated code.

Instead, let's call XenHypercallIsAvailable() in the driver's entry point,
and exit cleanly when the driver is started on a non-Xen platform.

Modify the constructor of XenConsoleSerialPortLib similarly; we shouldn't
proceed if Xen is not available. In practice this check should never fail,
because XenConsoleSerialPortLib is only used on ARM, and
ArmXenHypercallLib is always available; but nonetheless we should be
pedantic.

Laszlo Ersek b5d85f6221 OvmfPkg: XenHypercallLib: add empty constructor for ARM & AARCH64
In the next patch we'll add a simple query function to the XenHypercallLib
library class that is supposed to be called by initialization code in
modules. Among those, in constructors of dependent libraries too.

Library construction ordering is ensured only between libraries with
constructors, plus we shouldn't allow a dependent library with a
constructor to call into any XenHypercallLib instances (the simple query
function) before XenHypercallLib is constructed itself. For this reason,
introduce an (empty) constructor for ARM & AARCH64 too.

Laszlo Ersek 818bc86aa7 OvmfPkg: AcpiPlatformDxe: make dependency on PCI enumeration dynamic
SVN r16411 delayed ACPI table installation until PCI enumeration was
complete, because on QEMU the ACPI-related fw_cfg files should have been
downloaded only after PCI enumeration. Said commit implemented the
dependency by tightening the module's depex.

This patch replaces the EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL depex with a
matching protocol registration callback. The depex was static, and it
could not handle dynamically discovered situations when the dependency
would turn out invalid.

Namely:

- At the moment, the depex in "QemuFwCfgAcpiPlatformDxe.inf" assumes
  that "ArmPlatformPkg/ArmVirtualizationPkg/ArmVirtualizationQemu.dsc"
  lacks PCI support. However, PCI support is about to become run-time
  discoverable on that platform. If PCI support is missing, then
  ArmVirtualizationPkg will set PcdPciDisableBusEnumeration to TRUE.

  Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the
  dependency by not registering the callback and installing the ACPI
  tables right away.

- InitializeXen() in "OvmfPkg/PlatformPei/Xen.c" sets
  PcdPciDisableBusEnumeration to TRUE. This causes
  PciBusDriverBindingStart() in "MdeModulePkg/Bus/Pci/PciBusDxe/PciBus.c"
  to set gFullEnumeration to FALSE, which in turn makes PciEnumerator() in
  "MdeModulePkg/Bus/Pci/PciBusDxe/PciEnumerator.c" branch to
  PciEnumeratorLight(). The installation of
  EFI_PCI_ENUMERATION_COMPLETE_PROTOCOL at the end of PciEnumerator() is
  not reached.

  Which means that starting with SVN r16411, AcpiPlatformDxe is never
  dispatched on Xen.

  Hence, when PcdPciDisableBusEnumeration is TRUE, we invalidate the
  dependency by not registering the callback and installing the ACPI
  tables right away.

Laszlo Ersek 9253c14d41 OvmfPkg: QemuBootOrderLib: expose QEMU's "-boot menu=on[,splash-time=N]"
The QEMU command line option

  -boot menu=on

is meant to have the guest firmware wait for a firmware-specific interval
for the user to enter the boot menu. During the wait, the user can opt to
enter the boot menu, or interrupt the wait and proceed to booting at once.
If the wait interval elapses, the firmware should boot as it normally
would.

The QEMU command line option

  -boot menu=on,splash-time=N

means the same, except the firmware should wait for cca. N milliseconds
instead of a firmware-specific interval.

We can approximate this behavior quite well for edk2's virtual platforms
because the Intel BDS front page already supports a progress bar, with
semantics similar to the above. Let's distill the fw_cfg bits underlying
"-boot menu=on,splash-time=N" for the BDS policies, in the form of a
timeout value they can pass to Intel's PlatformBdsEnterFrontPage().

If the boot menu is not requested, we return
"gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPlatformBootTimeOut", which
is what the virtual platforms use right now.

If the boot menu is requested without specifying the timeout, we return
the same PCD, unless it would cause us to skip the boot menu at once. In
the latter case, we return 3 seconds (as an approximation of the 2500 ms
SeaBIOS default.)

Laszlo Ersek 2f9c55cc1d OvmfPkg: QemuBootOrderLib: featurize PCI-like device path translation
In preparation for adding OpenFirmware-to-UEFI translation for "MMIO-like"
OFW device path fragments, let's turn the currently exclusive "PCI-like"
translation into "just one" of the possible translations.

- Rename TranslateOfwNodes() to TranslatePciOfwNodes(), because it is
  tightly coupled to "PCI-like" translations.

- Rename REQUIRED_OFW_NODES to REQUIRED_PCI_OFW_NODES, because this macro
  is specific to TranslatePciOfwNodes().

- Introduce a new wrapper function under the original TranslateOfwNodes()
  name. This function is supposed to try translations in some order until
  a specific translation returns a status different from
  RETURN_UNSUPPORTED.

- Introduce a new Feature PCD that controls whether PCI translation is
  attempted at all.

- The boot option "survival policy" in BootOrderComplete() must take into
  account if the user was able to select PCI-like boot options. If the
  user had no such possibility (because the Feature PCD was off for
  PCI-like translation), then we ought to keep any such unselected boot
  options.

Since the TcpDxe, UefiPxeBcDxe, and IScsiDxe drivers in NetworkPkg also
support IPv4, we replace the ones in MdeModulePkg.

To enable the IPv6 support, build OVMF with "-D NETWORK_IP6_ENABLE".
A special case is NetworkPkg/IScsiDxe. It requires openssl. For convenience,
NetworkPkg/IScsiDxe is enabled only if both IPv6 and SecureBoot are enabled.

the ACPI data is rebuilt at the first time any of the related fw_cfg files
are read, through the acpi_build_update() fw_cfg read-callback function:

  fw_cfg_read()                                     [hw/nvram/fw_cfg.c]
    acpi_build_update()                             [hw/i386/acpi-build.c]
      acpi_build()

(See qemu commit d87072ceeccf4f84a64d4bc59124bcd64286c070 and its
containing series.)

For this reason we must not dispatch AcpiPlatformDxe before PciBusDxe
completes the enumeration.

Luckily, the PI Specification 1.3 defines
EFI_PCI_ENUMERATION_COMPLETE_GUID in Volume 5, "10.9 End of PCI
Enumeration Overview", as an indicia to inform the platform when the PCI
enumeration process has completed. PciBusDxe installs this protocol at the
end of the PciEnumerator() function.

Let's add this GUID to the Depex section of AcpiPlatformDxe, in order to
state the dependency explicitly.

On Xen, and on older QEMU where the linker/loader fw_cfg interface is
unavailable, this introduces a harmless ordering constraint -- we'll
always include PciBusDxe in OVMF, so the dependency will always be
satisfied.

I tested this change as follows:

- I dumped the ACPI tables in a Fedora 20 guest, before and after the
  change, and compared them. The only thing that actually changed was the
  FACS address. (Which I promptly tested with S3 suspend/resume.) Plus, of
  course, the FACP checksum changed, because the FACP links the FACS.

- Tested S3 in my Windows Server 2008 R2 and Windows Server 2012 R2 guests.

Scott Duplichan f7e899c7c7 OvmfPkg: flash driver: drop needlessly wide multiplication (VS2010)
The current types of subexpressions used in QemuFlashPtr() are as follows.
(We also show the types of "larger" subexpressions, according to operator
binding.)

  mFlashBase + (Lba * mFdBlockSize) + Offset
      ^          ^         ^            ^
      |          |         |            |
   (UINT8*)   EFI_LBA    UINTN        UINTN
              (UINT64)

  ---------------------------------   ------
              (UINT8*)                UINTN

  ------------------------------------------
                    (UINT8*)

When building with VS2010 for Ia32 / NOOPT, the 64-by-32 bit
multiplication is translated to an intrinsic, which is not allowed in
edk2.

Recognize that "Lba" is always bounded by "mFdBlockCount" (an UINTN) here
-- all callers of QemuFlashPtr() ensure that. In addition, the flash chip
in question is always under 4GB, which is why we can address it at all on
Ia32. Narrow "Lba" to UINTN, without any loss of range.

Laszlo Ersek 1c59015281 OvmfPg: flash driver: drop gratuitous 64-by-32 bit divisions (VS2010)
In the InitializeVariableFvHeader() function, all three of "Offset",
"Start" and "BlockSize" have type UINTN. Therefore the (Offset /
BlockSize) and (Start / BlockSize) divisions can be compiled on all
platforms without intrinsics.

In the current expressions

  (EFI_LBA) Offset / BlockSize
  (EFI_LBA) Start / BlockSize

"Offset" and "Start" are cast to UINT64 (== EFI_LBA), which leads to
64-by-32 bit divisions on Ia32, breaking the VS2010 / NOOPT / Ia32 build.
The simplest way to fix them is to realize we don't need casts at all.
(The prototypes of QemuFlashEraseBlock() and QemuFlashWrite() are visible
via "QemuFlash.h", and they will easily take our UINTN quotients as
UINT64.)

Laszlo Ersek 1e62c89c3a OvmfPg: flash driver: fix type of EFI_SIZE_TO_PAGES argument (VS2010)
The MarkMemoryRangeForRuntimeAccess() function passes the Length parameter
(of type UINT64) to the macro EFI_SIZE_TO_PAGES(). When building for the
Ia32 platform, this violates the interface contract of the macro:

    [...] Passing in a parameter that is larger than UINTN may produce
    unexpected results.

In addition, it trips up compilation by VS2010 for the Ia32 platform and
the NOOPT target -- it generates calls to intrinsics, which are not
allowed in edk2.

Fix both issues with the following steps:

(1) Demote the Length parameter of MarkMemoryRangeForRuntimeAccess() to
UINTN. Even a UINT32 value is plenty for representing the size of the
flash chip holding the variable store. Length parameter is used in the
following contexts:
- passed to gDS->RemoveMemorySpace() -- takes an UINT64
- passed to gDS->AddMemorySpace() -- ditto
- passed to EFI_SIZE_TO_PAGES() -- requires an UINTN. This also guarantees
  that the return type of EFI_SIZE_TO_PAGES() will be UINTN, hence we can
  drop the outer cast.

(2) The only caller of MarkMemoryRangeForRuntimeAccess() is
FvbInitialize(). The latter function populates the local Length variable
(passed to MarkMemoryRangeForRuntimeAccess()) from
PcdGet32(PcdOvmfFirmwareFdSize). Therefore we can simply demote the local
variable to UINTN in this function as well.
- There's only one other use of Length in FvbInitialize(): it is passed to
  GetFvbInfo(). GetFvbInfo() takes an UINT64, so passing an UINTN is fine.

Gabriel Somlo 2e70cf8ade OvmfPkg: PlatformBdsLib: Platform dependent PCI/IRQ initialization
Merge PciInitialization() and AcpiInitialization() into a single
function, PciAcpiInitialization(), and use a PCD set during PEI to
detect the underlying platform type (PIIX4 or Q35/MCH) and therefore
the addresses of the registers to be initialized.

Add LNK[A-H] routing target initialization for the Q35 platform.

Additionally, initialize PCI_INTERRUPT_LINE registers for the typical
set of PCI devices included by QEMU with the Q35 machine type. The
corresponding PIIX4 initialization of PCI_INTERRUPT_LINE registers is
cleaned up and the list of PIIX4 PCI devices updated to the list
typically included with QEMU.

NOTE: The list of PCI devices for which we initialize PCI_INTERRUPT_LINE
is hard-coded, and, depending on how QEMU devices are configured on
the command line, may miss some devices, or (harmlessly) attempt to
initialize devices which are not present in the system. A subsequent
patch will replace this hard-coded list with a mechanism to correctly
initialize PCI_INTERRUPT_LINE for applicable present PCI devices only.

Remove local power management register access macros in favor of

Next, AcpiTimerLib is split out into three instances, for use during
various stages:

  - BaseRom: used during SEC, PEI_CORE, and PEIM;
  - Dxe:     used during DXE_DRIVER and DXE_RUNTIME_DRIVER;
  - Base:    used by default during all other stages.

Most of the code remains in AcpiTimerLib.c, to be shared by all
instances. The two platform-dependent methods (constructor and
InternalAcpiGetTimerTick) are provided separately by source files
specific to each instance, namely [BaseRom|Base|Dxe]AcpiTimerLib.c.

Since pre-DXE stages can't rely on storing data in global variables,
methods specific to the "BaseRom" instance will call platform
detection macros each time they're invoked.

The "Base" instance calls platform detection macros only from its
constructor, and caches the address required by InternalAcpiTimerTick
in a global variable.

The "Dxe" instance is very similar to "Base", except no platform
detection macros are called at all; instead, the platform type is
read via a dynamic PCD set from PlatformPei.

Laszlo Ersek b1220e2820 OvmfPkg: BDS: drop custom boot timeout, revert to IntelFrameworkModulePkg's
PlatformBdsEnterFrontPage() already implements a keypress wait (for
entering the setup utility at boot) with a nice progress bar, only OVMF
has not been using it.

Removing our custom code and utilizing PlatformBdsEnterFrontPage()'s
builtin wait has the following benefits:

- It simplifies OVMF's BDS code.

- Because now we call PlatformBdsEnterFrontPage() unconditionally, it
  actually has a chance to look at the EFI_OS_INDICATIONS_BOOT_TO_FW_UI
  bit of the "OsIndications" variable, improving compliance with the UEFI
  specification. References:
  - https://bugzilla.redhat.com/show_bug.cgi?id=1153927
  - http://thread.gmane.org/gmane.comp.bios.tianocore.devel/10487

- The progress bar looks nice. (And it keeps the earlier behavior intact,
  when the user presses a key on the TianoCore splash screen.)

  In any case, we set the timeout to 0 (which doesn't show the progress
  bar and proceeds to the boot options immediately) in order to keep the
  boot time down.

Laszlo Ersek 547222da31 OvmfPkg: BDS: optimize second argument in PlatformBdsEnterFrontPage() call
The second parameter of said function is "ConnectAllHappened", and if set
to TRUE, the function sets "gConnectAllHappened" to TRUE.

This global variable in turn controls whether Intel BDS code *itself*
calls BdsLibConnectAllDriversToAllControllers() in various places -- if
the indicator is TRUE, then the "connect all" is assumed to have been
performed, and Intel BDS doesn't do it itself.

OVMF should pass TRUE as "ConnectAllHappened", because a few lines before
our call to PlatformBdsEnterFrontPage(), we already connect everything
with BdsLibConnectAll(), which includes the effects of
BdsLibConnectAllDriversToAllControllers():

PlatformBdsPolicyBehavior()                   [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]

Laszlo Ersek 5126ef789d OvmfPkg: BDS: don't overwrite the BDS Front Page timeout
The PlatformBdsEnterFrontPage() function's first parameter,
"TimeoutDefault", determines the behavior of the setup utility:

- If (TimeoutDefault == 0), then the usual boot order is to be acted upon
  immediately.

- If (TimeoutDefault == 0xFFFF), then the setup utility is entered
  unconditionally.

- If (0 < TimeoutDefault && TimeoutDefault < 0xFFFF), then the
  PlatformBdsEnterFrontPage() function displays a progress bar, waiting
  for TimeoutDefault seconds. If the user presses a key, then the setup
  utility is entered, otherwise the normal boot option processing takes
  place.

The TimeoutDefault parameter is supposed to be set from

  gEfiIntelFrameworkModulePkgTokenSpaceGuid.PcdPlatformBootTimeOut

which has the following (matching) documentation in
"IntelFrameworkModulePkg/IntelFrameworkModulePkg.dec":

  The number of seconds that the firmware will wait before initiating the
  original default boot selection.
  A value of 0 indicates that the default boot selection is to be
  initiated immediately on boot.
  The value of 0xFFFF then firmware will wait for user input before
  booting.

OVMF does this actually -- see the Timeout variable in
PlatformBdsPolicyBehavior() -- but right before calling
PlatformBdsEnterFrontPage(), OVMF hardwires TimeoutDefault to 0xFFFF.

This has been acceptable until now, because OVMF implements its own "wait
for keypress at the splash screen" logic in PlatformBdsPolicyBehavior(),
completely avoiding the progress bar mentioned above. OVMF only calls
PlatformBdsEnterFrontPage() when the user presses a key during its own
"splash screen wait", and *then* it indeed makes sense to enter the setup
utility unconditionally.

However, even that way, the

  Timeout = 0xffff;

assignment is superfluous, because 0xFFFF is already the default value of
PcdPlatformBootTimeOut in "IntelFrameworkModulePkg.dec", and OvmfPkg
doesn't override it in its DSC files.

  commit message
- Have a mandatory sector-size multiple of 512 or fail to initialize.
- use Sector instead of Offset for IO request.
  with Sector been 512-byte unit.
- print something if EventChannelNotify return an error.

Change in V2:
- trigger CoW is probably not needed on OVMF (as opposed to Mini-OS),
  removed the test.
- comments
- renamed XenbusReadInteger to XenBusReadUint64
- remove callback from IoData, use simple status instead
- return a status from the synchronus io
- Close protocol if blockfront init fail.
- fix few debug print
- Rename XenbusIo to XenBusIo
- XenPvBlkWaitForBackendState will return an error if the new backend
  states is not the expected state.
