Brijesh Singh fc2c1543e5 OvmfPkg/VirtioLib: take VirtIo instance in VirtioRingInit/VirtioRingUninit
Passing the VirtIo protocol instance will allow the vring to use
VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages () to allocate vring buffer.

Brijesh Singh 0a78d754ed OvmfPkg/VirtioLib: add VirtioMapAllBytesInSharedBuffer() helper function
The function can be used for mapping the system physical address to virtio
device address using VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer (). The
function helps with centralizing error handling, and it allows the caller
to pass in constant or other evaluated expressions for NumberOfBytes.

Brijesh Singh f6c909ae5d OvmfPkg/QemuFwCfgLib: Use BusMasterCommonBuffer to map FW_CFG_DMA_ACCESS
Commit 09719a01b1 (OvmfPkg/QemuFwCfgLib: Implement SEV internal function
for Dxe phase) uses IOMMU protocol to allocate and free FW_CFG_DMA_ACCESS
buffer when SEV is active. During initial commits we made assumption that
IOMMU.AllocateBuffer() will provide PlainTextAddress (i.e C-bit cleared).
This assumption was wrong, the AllocateBuffer() protocol member is not
expected to produce a buffer that is immediatly usable, and client is
required to call Map() uncondtionally with BusMasterCommonBuffer[64] to
get a mapping which is accessable by both host and device.

The patch refactors code a bit and add the support to Map()
FW_CFG_DMA_ACCESS buffer using BusMasterCommonBuffer operation after
allocation and Unamp() before free.

The complete discussion about this and recommendation from Laszlo can be
found here [1]

Brijesh Singh e508e069a8 OvmfPkg/QemuFwCfgLib: Suppress GCC49 IA32 build failure
NumPages variable was introduced in commit 66c548be50. In this commit
we allocate an intermediate buffer when SEV is enabled. The 'BounceBuffer'
variable points to the intermediate buffer pointer and NumPages variables
stores the number of pages. Later in the code, 'BounceBuffer' variable is
checked to see if we need to free the intermediate buffers. The code looks
correct, suppress the warning.

Laszlo Ersek 7bb57805ba OvmfPkg/QemuFwCfgS3Lib: implement opcode APIs for DXE fw_cfg instance
In the DXE fw_cfg instance:

- QemuFwCfgS3Enabled() queries S3 enablement via fw_cfg. This behavior is
  shared with the PEI fw_cfg instance, and the DXE fw_cfg instance already
  pulls in the function from "QemuFwCfgS3PeiDxe.c".

- If QemuFwCfgS3Enabled() returns TRUE, the client module is permitted to
  call QemuFwCfgS3CallWhenBootScriptReady().

  We provide a fully functional implementation for
  QemuFwCfgS3CallWhenBootScriptReady(). A protocol notify is installed at
  TPL_CALLBACK for EFI_S3_SAVE_STATE_PROTOCOL. If / once the protocol is
  available, the client module's Callback() function is called, which is
  expected to produce ACPI S3 Boot Script opcodes using the helper
  functions listed below. In QemuFwCfgS3CallWhenBootScriptReady(), we also
  allocate a reserved memory buffer, sized & typed by the client module,
  for the opcodes and (internally) the fw_cfg DMA operations to work upon,
  during S3 resume.

  This behavior is unique to the DXE fw_cfg instance. Thus, add the
  function to "QemuFwCfgS3Dxe.c".

- The QemuFwCfgS3ScriptWriteBytes(), QemuFwCfgS3ScriptReadBytes(),
  QemuFwCfgS3ScriptSkipBytes(), and QemuFwCfgS3ScriptCheckValue()
  functions are also implemented usefully, since the client module's
  Callback() function is expected to invoke them.

  Each of the first three functions produces MEM_WRITE, IO_WRITE, and
  MEM_POLL opcodes, to set up the DMA command in reserved memory, to start
  the DMA transfer, and to check the DMA result, respectively.

  The QemuFwCfgS3ScriptCheckValue() function produces a MEM_POLL opcode to
  validate an unsigned integer field in data that was read via
  QemuFwCfgS3ScriptReadBytes().

  This behavior is again unique to the DXE fw_cfg instance, so add the
  functions to "QemuFwCfgS3Dxe.c".

  shared with the DXE fw_cfg instance, and the PEI fw_cfg instance already
  pulls in the function from "QemuFwCfgS3PeiDxe.c".

- If QemuFwCfgS3Enabled() returns TRUE, the client module is permitted to
  call QemuFwCfgS3CallWhenBootScriptReady(). However, in the PEI phase we
  have no support for capturing ACPI S3 Boot Script opcodes, hence we
  return RETURN_UNSUPPORTED unconditionally. This behavior is unique to
  the PEI fw_cfg instance, so add the function to "QemuFwCfgS3Pei.c".

- Consequently, the QemuFwCfgS3ScriptWriteBytes(),
  QemuFwCfgS3ScriptReadBytes(), QemuFwCfgS3ScriptSkipBytes(), and
  QemuFwCfgS3ScriptCheckValue() functions must never be called. (They
  could only be called from the client module's callback, but
  QemuFwCfgS3CallWhenBootScriptReady() will never install such callback in
  the PEI fw_cfg instance -- see above.)

  This behavior is not unique to the PEI fw_cfg instance (it is shared
  with the Base Null instance), so pull in these functions from
  "QemuFwCfgS3BasePei.c".

Michael Kinney f4d575b51b OvmgPkg/PlatformBootManagerLib: Add Debug Agent console
The Debug Agent in the SourceLevelDebugPkg can multiplex
both source level debug messages and console messages on
the same UART.  When this is done, the Debug Agent owns
the UART device and an additional device handle with a
Serial I/O Protocol is produced with a VenHw device path
node.

In order for a platform to provide a UART based console
when the Debug Agent is using the same UART device, the
PlatformBootManagerLib must consider the SerialI/O
Protocol produces by the Debug Agent as one of the
supported consoles.

Laszlo Ersek 2c8dcbc65a OvmfPkg/QemuFwCfgLib: support QEMU's DMA-like fw_cfg access method
The benefits of the DMA-like access method are (a) speed, (b) write
support in QEMU 2.9+.

(IOPort-based write support was discontinued in QEMU 2.4, and the
DMA-based one is being added to QEMU 2.9. Write support needs no separate
feature detection because writeability is governed on the level of
individual fw_cfg files -- if a file meant to be written by the firmware
exists in the directory, then it is writeable with the DMA method.)

We don't enable this feature for the SEC library instance, because:
- the SEC instance remains without clients (I've checked that it builds
  though),
- in SEC, any possible fw_cfg use is expected to be small and read-only.

Laszlo Ersek 5297c0bf83 OvmfPkg/QemuFwCfgLib: move InternalQemuFwCfgIsAvailable() to lib instances
InternalQemuFwCfgIsAvailable() is an API that is incorrectly exposed by
the "OvmfPkg/Include/Library/QemuFwCfgLib.h" library class header; the API
is meant to be used internally to library instances (if it's needed at
all).

In OvmfPkg, we have two lib instances (for SEC and PEI/DXE); they provide
different implementations of InternalQemuFwCfgIsAvailable(), for the
shared file "OvmfPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c". Move the API
declaration to a new internal header called "QemuFwCfgLibInternal.h", and
drop EFIAPI in the process.

Laszlo Ersek d796d33f18 OvmfPkg/QemuBootOrderLib: drop too strict "/HD(" suffix from vblk prefix
Translating QEMU's virtio-block OpenFirmware device path to a UEFI device
path prefix was one of the earliest case handled in QemuBootOrderLib. At
that time, I terminated the translation output (the UEFI devpath prefix)
with a "/HD(" suffix.

The intent was for the translation to prefix-match only boot options with
HD() device path nodes in them, that is, no auto-generated "device level"
boot options. This was motivated by prioritizing specific boot options
created by OS installers over auto-generated "device level" options.

However, practice has shown that:

- OS installers place their installed boot options first in the boot order
  anyway,

- other device types (SATA disks, virtio-scsi disks), where "/HD(" is not
  appended, work just fine,

- requiring "/HD(" actually causes problems: after the OS-installed
  specific boot option has been lost (or purposely removed), the
  auto-generated "device level" boot option does the right thing (see the
  Default Boot Behavior under
  <http://blog.uncooperative.org/blog/2014/02/06/the-efi-system-partition/>).
  The "/HD(" requirement causes such boot options to be dropped, which
  prevents "fallback.efi" from running.

Relax the matching by removing the "/HD(" suffix from the translated
prefix.
