Brijesh Singh e60af8a1eb OvmfPkg/ResetVector: Set C-bit when building initial page table
SEV guest VMs have the concept of private and shared memory. Private
memory is encrypted with the guest-specific key, while shared memory
may be encrypted with hypervisor key. Certain types of memory (namely
instruction pages and guest page tables) are always treated as private
memory by the hardware. The C-bit in PTE indicate whether the page is
private or shared. The C-bit position for the PTE can be obtained from
CPUID Fn8000_001F[EBX].

When SEV is active, the BIOS is encrypted by the Qemu launch sequence,
we must set the C-bit when building the page table.

Laszlo Ersek d5e064447f OvmfPkg/PlatformPei: honor extended TSEG in PcdQ35TsegMbytes if available
Recognize an extended TSEG when available in
Q35TsegMbytesInitialization(), and set both PcdQ35TsegMbytes (for
OvmfPkg/SmmAccess) and "mQ35TsegMbytes" (for PlatformPei's own use)
accordingly. The new logic interfaces with the QEMU feature added in QEMU
commit 2f295167e0c4 ("q35/mch: implement extended TSEG sizes",
2017-06-08).

At this point we have to explicitly restrict Q35TsegMbytesInitialization()
to the Q35 board, but that's OK, because Q35TsegMbytesInitialization() is
only called when PcdSmmSmramRequire is set, and for that Q35 is already an
enforced requirement.

Laszlo Ersek 6812bb7bb5 OvmfPkg/SmmAccess: support extended TSEG size
In SmmAccessPeiEntryPoint(), map TSEG megabyte counts different from 1, 2
and 8 to the MCH_ESMRAMC_TSEG_EXT bit pattern (introduced in the previous
patch), for the ESMRAMC.TSEG_SZ bit-field register. (Suggested by Jordan.)

In SmramAccessGetCapabilities() -- backing both
PEI_SMM_ACCESS_PPI.GetCapabilities() and
EFI_SMM_ACCESS2_PROTOCOL.GetCapabilities() --, map the
MCH_ESMRAMC_TSEG_EXT bit pattern found in the ESMRAMC.TSEG_SZ bit-field
register to a byte count of (mQ35TsegMbytes * SIZE_1MB).

(MCH_ESMRAMC_TSEG_EXT is the only possible pattern if none of
MCH_ESMRAMC_TSEG_1MB, MCH_ESMRAMC_TSEG_2MB, and MCH_ESMRAMC_TSEG_8MB
match.)

The new code paths are not exercised just yet; for that, PlatformPei is
going to have to set PcdQ35TsegMbytes (and consequently, SmramInternal's
"mQ35TsegMbytes") to a value different from 1, 2, and 8.

Laszlo Ersek 1372f8d347 OvmfPkg/SmmAccess: prepare for PcdQ35TsegMbytes becoming dynamic
In one of the next patches we'll turn PcdQ35TsegMbytes into a dynamic PCD,
to be set by PlatformPei.

Jordan suggested to use gEfiPeiMemoryDiscoveredPpiGuid as SmmAccessPei's
DEPEX for making sure that PlatformPei sets the PCD before SmmAccessPei
consumes it. (PlatformPei installs the permanent PEI RAM.) Such a DEPEX is
supposed to mirror physical firmware, where anything related to SMRAM
cannot run before said platform's physical RAM is discovered (signaled by
the presence of gEfiPeiMemoryDiscoveredPpiGuid).

Introduce the InitQ35TsegMbytes() function and the "mQ35TsegMbytes" extern
variable to "SmramInternal.h" and "SmramInternal.c":

- Both SmmAccess modules (PEIM and DXE driver) are supposed to call
  InitQ35TsegMbytes() in their respective entry point functions, saving
  PcdQ35TsegMbytes into "mQ35TsegMbytes". This way dynamic PCD fetches can
  be kept out of PEI_SMM_ACCESS_PPI and EFI_SMM_ACCESS2_PROTOCOL member
  functions later (when we add support for extended TSEG size).

- We can thus replace the current PcdQ35TsegMbytes fetches in
  SmmAccessPei's entry point function as well, with reads from
  "mQ35TsegMbytes".

Laszlo Ersek 504f149100 OvmfPkg: disable build-time relocation for DXEFV modules
When the GenFv utility from BaseTools composes a firmware volume, it
checks whether modules in the firmware volume are subject to build-time
relocation. The primary indication for relocation is whether the firmware
volume has a nonzero base address, according to the [FD] section(s) in the
FDF file that refer to the firmware volume.

The idea behind build-time relocation is that XIP (execute in place)
modules will not be relocated at boot-time:

- Pre-DXE phase modules generally execute in place.

  (OVMF is no exception, despite the fact that we have writeable memory
  even in SEC: PEI_CORE and PEIMs run in-place from PEIFV, after SEC
  decompresses PEIFV and DXEFV from FVMAIN_COMPACT (flash) to RAM.
  PEI_CORE and the PEIMs are relocated at boot-time only after PlatformPei
  installs the permanent PEI RAM, and the RAM migration occurs.)

- Modules dispatched by the DXE Core are generally relocated at boot-time.
  However, this is not necessarily so. Quoting Liming from
  <https://lists.01.org/pipermail/edk2-devel/2017-July/012053.html>:

> PI spec has no limitation that XIP is for PEIM only. DXE driver may be
> built as XIP for other purpose. For example, if DXE driver image address
> is not zero, DxeCore will try allocating the preferred address and load
> it. In another case, once DXE driver is relocated at build time, DxeCore
> will dispatch it and start it directly without loading, it may save boot
> performance.

Therefore GenFv relocates even DXE and UEFI driver modules if the
containing firmware volume has a nonzero base address.

In OVMF, this is the case for both PEIV and DXEFV:

> [FD.MEMFD]
> BaseAddress   = $(MEMFD_BASE_ADDRESS)
> Size          = 0xB00000
> ErasePolarity = 1
> BlockSize     = 0x10000
> NumBlocks     = 0xB0
> ...
> 0x020000|0x0E0000
> gUefiOvmfPkgTokenSpaceGuid.PcdOvmfPeiMemFvBase|gUefiOvmfPkgTokenSpaceGuid.PcdOvmfPeiMemFvSize
> FV = PEIFV
>
> 0x100000|0xA00000
> gUefiOvmfPkgTokenSpaceGuid.PcdOvmfDxeMemFvBase|gUefiOvmfPkgTokenSpaceGuid.PcdOvmfDxeMemFvSize
> FV = DXEFV

While the build-time relocation certainly makes sense for PEIFV (see
above), the reasons for which we specify DXEFV under [FD.MEMFD] are
weaker:

- we set the PcdOvmfDxeMemFvBase and PcdOvmfDxeMemFvSize PCDs here,

- and we ascertain that DXEFV, when decompressed by SEC from
  FVMAIN_COMPACT, will fit into the area allotted here, at build time.

In other words, the build-time relocation of the modules in DXEFV is a
waste of resources. But, it gets worse:

Build-time relocation of an executable is only possible if the on-disk and
in-memory layouts are identical, i.e., if the sections of the PE/COFF
image adhere to the same alignment on disk and in memory. Put differently,
the FileAlignment and SectionAlignment headers must be equal.

For boot-time modules that we build as part of edk2, both alignment values
are 0x20 bytes. For runtime modules that we build as part of edk2, both
alignment values are 0x1000 bytes. This is why the DXEFV relocation,
albeit wasteful, is also successful every time.

Unfortunately, if we try to include a PE/COFF binary in DXEFV that
originates from outside of edk2, the DXEFV relocation can fail due to the
binary having unmatched FileAlignment and SectionAlignment headers. This
is precisely the case with the E3522X2.EFI network driver for the e1000
NIC, from Intel's BootUtil / PREBOOT.EXE distribution.

The solution is to use the FvForceRebase=FALSE override under [FV.DXEFV].
This tells GenFv not to perform build-time relocation on the firmware
volume, despite the FV having a nonzero base address.

In DXEFV we also have SMM drivers. Those are relocated at boot-time (into
SMRAM) unconditionally; SMRAM is always discovered at boot-time.

Kudos to Ard and Liming for the PE/COFF sections & relocations
explanation, and for the FvForceRebase=FALSE tip.

I regression-tested this change in the following configurations (all with
normal boot and S3 suspend/resume):

  IA32,     q35,     SMM,     Linux
  IA32X64,  q35,     SMM,     Linux
  IA32X64,  q35,     SMM,     Windows-8.1
  X64,      i440fx,  no-SMM,  Linux

Laszlo Ersek 4275f38507 OvmfPkg/AcpiPlatformDxe: alloc blobs from 64-bit space unless restricted
... by narrower than 8-byte ADD_POINTER references.

Introduce the CollectAllocationsRestrictedTo32Bit() function, which
iterates over the linker/loader script, and collects the names of the
fw_cfg blobs that are referenced by QEMU_LOADER_ADD_POINTER.PointeeFile
fields, such that QEMU_LOADER_ADD_POINTER.PointerSize is less than 8. This
means that the pointee blob's address will have to be patched into a
narrower-than-8 byte pointer field, hence the pointee blob must not be
allocated from 64-bit address space.

In ProcessCmdAllocate(), consult these restrictions when setting the
maximum address for gBS->AllocatePages(). The default is now MAX_UINT64,
unless restricted like described above to the pre-patch MAX_UINT32 limit.

In combination with Ard's QEMU commit cb51ac2ffe36 ("hw/arm/virt: generate
64-bit addressable ACPI objects", 2017-04-10), this patch enables
OvmfPkg/AcpiPlatformDxe to work entirely above the 4GB mark.

(An upcoming / planned aarch64 QEMU machine type will have no RAM under
4GB at all. Plus, moving the allocations higher is beneficial to the
current "virt" machine type as well; in Ard's words: "having all firmware
allocations inside the same 1 GB (or 512 MB for 64k pages) frame reduces
the TLB footprint".)

Laszlo Ersek 7e8329267e OvmfPkg/EmuVariableFvbRuntimeDxe: change block size to 4KB
EmuVariableFvbRuntimeDxe currently produces a Firmware Volume Block
protocol that is based on a block map of two blocks, each block having
PcdFlashNvStorageFtwSpareSize for size.

(The total size is 2 * PcdFlashNvStorageFtwSpareSize.)

FaultTolerantWriteDxe in turn expects the block size to be a power of two.

In the 4MB build of OVMF, PcdFlashNvStorageFtwSpareSize is 264KB, which is
not a power of two. In order to equip EmuVariableFvbRuntimeDxe for this
build, shrink the block size to 4KB (EFI_PAGE_SIZE), and grow the block
count from 2 to EFI_SIZE_TO_PAGES(2 * PcdFlashNvStorageFtwSpareSize). The
total size remains

  2 * PcdFlashNvStorageFtwSpareSize
  --------------------------------- * EFI_PAGE_SIZE
            EFI_PAGE_SIZE

Right now EmuVariableFvbRuntimeDxe open-codes the block count of 2 in
various limit checks, so introduce a few new macros:
- EMU_FVB_NUM_TOTAL_BLOCKS, for the LHS of the above product,
- EMU_FVB_NUM_SPARE_BLOCKS for the half of that.

Also rework the FVB protocol members to support an arbitrary count of
blocks.

Keep the invariant intact that the first half of the firmware volume hosts
the variable store and the FTW working block, and that the second half
maps the FTW spare area.

Currently the default (module type independent) PcdLib resolution is to
BasePcdLibNull.inf, which is inherited by all PEIMs. In the next patch,
we'll flip the PEIM default resolution to PeiPcdLib.inf, but in order to
keep that patch both correct and simple to review, we should spell out the
Null resolution for those two PEIMs (ReportStatusCodeRouterPei and
StatusCodeHandlerPei) that are now the only ones that don't specify an
explicit resolution.

Laszlo Ersek 5e167d7e78 OvmfPkg/PlatformPei: don't allocate reserved mem varstore if SMM_REQUIRE
For the emulated variable store, PlatformPei allocates reserved memory (as
early as possible, so that the address remains the same during reboot),
and PcdEmuVariableNvStoreReserved carries the address to
EmuVariableFvbRuntimeDxe.

However, EmuVariableFvbRuntimeDxe is excluded from the SMM_REQUIRE build,
and then noone consumes PcdEmuVariableNvStoreReserved. Don't waste
reserved memory whenever that's the case.

(Even a dynamic default for PcdEmuVariableNvStoreReserved would be
unnecessary; but that way the PcdSet64S() call in the
ReserveEmuVariableNvStore() function doesn't compile.)

Laszlo Ersek 62f43f7c19 OvmfPkg: sync PcdVariableStoreSize with PcdFlashNvStorageVariableSize
"MdeModulePkg/MdeModulePkg.dec" declares PcdVariableStoreSize like this:

> The size of volatile buffer. This buffer is used to store VOLATILE
> attribute variables.

There is no inherent reason why the size of the volatile variable store
should match the same of the non-volatile variable store. Indeed flash
variables in the 4MB build work fine without this equality.

However, OvmfPkg/EmuVariableFvbRuntimeDxe uses PcdVariableStoreSize to
initialize the non-volatile VARIABLE_STORE_HEADER too. (Presumably based
on the fact that ultimately that storage will not be permanent.) When
using EmuVariableFvbRuntimeDxe in the 4MB build, the mismatch between the
two mentioned PCDs (which is apparent through EmuVariableFvbRuntimeDxe's
VARIABLE_STORE_HEADER) triggers an assertion in the variable driver:

> ASSERT MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c(3772):
> mNvVariableCache->Size == VariableStoreLength

Bringing PcdVariableStoreSize in sync with PcdFlashNvStorageVariableSize
fixes this. It also happens to ensure a volatile store size in the 4MB
build that equals the non-volatile store size, which likely doesn't hurt
for symmetry.

Laszlo Ersek 0c79471d6a OvmfPkg/PlatformPei: handle non-power-of-two spare size for emu variables
In commit b24fca0575 ("OvmfPkg: introduce 4MB flash image (mainly) for
Windows HCK", 2017-04-29), I changed PcdFlashNvStorageFtwSpareSize to
264KB, in the then-new default 4MB build.

While PcdFlashNvStorageFtwSpareSize remains exactly half of the entire
non-volatile store (which is 528KB), 264KB isn't itself a power of two.
This triggers an assertion failure in AllocateAlignedRuntimePages() when
PlatformPei calls it from the ReserveEmuVariableNvStore() function,
passing PcdFlashNvStorageFtwSpareSize as the Alignment parameter:

> ASSERT MdePkg/Library/PeiMemoryAllocationLib/MemoryAllocationLib.c(196):
> (Alignment & (Alignment - 1)) == 0

Round up the alignment to the next power of two if necessary.

Laszlo Ersek b24fca0575 OvmfPkg: introduce 4MB flash image (mainly) for Windows HCK
The "Confirm64KilobytesOfUnauthenticatedVariableStorage" test case of the
Secure Boot Logo Test ("Microsoft.UefiSecureBootLogo.Tests") suite in the
Microsoft Hardware Certification Kit expects to be able to populate the
variable store up to roughly 64 KB, with a series of 1 KB sized,
unauthenticated variables. OVMF's current live varstore area is too small
for this: 56 KB.

Introduce the FD_SIZE_4MB build macro (equivalently, FD_SIZE_IN_KB=4096),
which

- enlarges the full flash image to 4MB -- QEMU supports up to 8MB, see
  FLASH_MAP_BASE_MIN in "hw/i386/pc_sysfw.c" --,

- inside that, grows the varstore area / pflash chip to 528 KB, and within
  it, the live area from 56 KB to 256 KB.

Importantly, a firmware binary built with -D FD_SIZE_4MB will *not* be
compatible with a variable store that originates from a variable store
template built *without* -D FD_SIZE_4MB. This is the reason for the large
increase, as every such change breaks compatibility between a new firmware
binary and old varstore files.

Enlarging the varstore does not impact the performance of normal
operations, as we keep the varstore block size 4KB. The performance of
reclaim is affected, but that is expected (since reclaim has to rework the
full live area). And, reclaim occurs proportionally less frequently.

While at it, the FVMAIN_COMPACT volume (with the compressed FFS file in
it) is also enlarged significantly, so that we have plenty of room for
future DXEFV (and perhaps PEIFV) increments -- DXEFV has been growing
steadily, and that increase shows through compression too. Right now the
PEIFV and DXEFV volumes need no resizing.

Here's a summary:

  Description                Compression type                Size [KB]

Laszlo Ersek 210270730c OvmfPkg: introduce the FD_SIZE_IN_KB macro / build flag
FD_SIZE_xMB defines have existed for flash size selection. They can be
passed as "-D FD_SIZE_xMB" on the command line. Passing multiple of them
at the same time has never been supported; earlier settings on the command
line cannot be overridden.

Introduce the integer valued FD_SIZE_IN_KB macro, which provides the
following improvements:

- several instances of it are permitted on the command line, with the last
  one taking effect,

- conditional statements in the DSC and FDF files need only check a single
  macro, and multiple values can be checked in a single !if with the ||
  operator,

- nested !ifdef / !else ladders can be replaced with flat equality tests,

- in the future, flash sizes can be expressed with a finer than MB
  granularity, if necessary.

For now, we're going to preserve the FD_SIZE_xMB defines as convenience
wrappers for FD_SIZE_IN_KB.

FD_SIZE_IN_KB is being added to the DSC files because this way we can
depend on it in both the DSC and FDF files.

Phil Dennis-Jordan c137d95081 OvmfPkg/QemuVideoDxe: VMWare SVGA device support
In addition to the QXL, Cirrus, etc. VGA adapters, Qemu also implements
a basic version of VMWare's SVGA display device. Drivers for this
device exist for some guest OSes which do not support Qemu's other
display adapters, so supporting it in OVMF is useful in conjunction
with those OSes.

This change adds support for the SVGA device's framebuffer to
QemuVideoDxe's graphics output protocol implementation, based on
VMWare's documentation. The most basic initialisation, framebuffer
layout query, and mode setting operations are implemented.

The device relies on port-based 32-bit I/O, unfortunately on misaligned
addresses. This limits the driver's support to the x86 family of
platforms.

Phil Dennis-Jordan 05a5379458 OvmfPkg/QemuVideoDxe: Helper functions for unaligned port I/O.
The VMWare SVGA display device implemented by Qemu (-vga vmware) uses
an I/O-type BAR which is laid out such that some register offsets are
not aligned to the read/write width with which they are expected to be
accessed. (The register value port has an offset of 1 and requires
32 bit wide read/write access.)

The EFI_PCI_IO_PROTOCOL's Io.Read/Io.Write functions do not support
such unaligned I/O.

Before a driver for this device can be added to QemuVideoDxe, helper
functions for unaligned I/O are therefore required. This adds the
functions UnalignedIoWrite32 and UnalignedIoRead32, based on IoLib's
IoWrite32 and IoRead32, for the Ia32 and X64 architectures. Port I/O
requires inline assembly, so implementations are provided for the GCC,
ICC, and Microsoft compiler families. Such I/O is not possible on other
architectures, a dummy (ASSERT()ing) implementation is therefore
provided to satisfy the linker.

Phil Dennis-Jordan 072060a6f8 OvmfPkg: Allow multiple add-pointer linker commands to same ACPI table
ACPI tables may contain multiple fields which point to the same
destination table. For example, in some revisions, the FADT contains
both DSDT and X_DSDT fields, and they may both point to the DSDT.

Previously, if Qemu created QEMU_LOADER_ADD_POINTER linker commands for
such instances, the linking process would attempt to install the same
pointed-to table repeatedly. For tables of which there must only be one
instance, the call to AcpiProtocol->InstallAcpiTable() would fail during
the second linker command pointing to the same table, thus entirely
aborting the ACPI table linking process. In the case of tables of which
there may be multiple instances, the table would end up duplicated.

This change adds a memoisation data structure which tracks the table
pointers that have already been processed; even if the same pointer is
encountered multiple times, it is only processed once.

We cannot entirely eliminate the manual boot script building in this

GEN_PMCON_1) at S3 resume, not just registers exposed via fw_cfg.

We can nonetheless replace the manually built opcodes for the latter class
of registers with QemuFwCfgS3Lib function calls. We preserve the ordering
between the two sets of registers (low-level chipset first, fw_cfg
second).

This patch demonstrates that manual handling of S3SaveState protocol
installation can be combined with QemuFwCfgS3Lib, even without upsetting
the original order between boot script fragments. An S3SaveState notify
function running at TPL_CALLBACK can safely queue another S3SaveState
notify function at TPL_CALLBACK with QemuFwCfgS3CallWhenBootScriptReady().

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".

Laszlo Ersek da58d987cc OvmfPkg/QemuFwCfgS3Lib: implement opcode APIs for PEI fw_cfg instance
In the PEI fw_cfg instance:

- QemuFwCfgS3Enabled() queries S3 enablement via fw_cfg. This behavior is
  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

  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".

"BootScript.c" with such comments on the PointerValue field of

the introduction of the PointeeOffset field.)

The code is fine as-is -- ProcessCmdWritePointer() already calls
SaveCondensedWritePointerToS3Context() correctly, and "BootScript.c"
itself is indifferent to the exact values --, but the comments in
"BootScript.c" should match reality too. Update them.

The Count parameter of RShiftU64() must be strictly smaller than 64.
ProcessCmdAddPointer() and ProcessCmdWritePointer() currently ensure this
by "cleverly" breaking the last bit of a potentially 8-byte right shift
out to a separate operation.

Instead, exclude the Count==64 case explicitly (in which case the
preexistent outer RShiftU64() would return 0), and keep only the inner
RShiftU64(), with the direct Count however.

This is not a functional change, just style improvement.

Laszlo Ersek df73df138d OvmfPkg/AcpiPlatformDxe: replay QEMU_LOADER_WRITE_POINTER commands at S3
Ultimately, each QEMU_LOADER_WRITE_POINTER command creates a guest memory
reference in some QEMU device. When the virtual machine is reset, the
device willfully forgets the guest address, since the guest memory is
wholly invalidated during platform reset.

... Unless the reset is part of S3 resume. Then the guest memory is
preserved intact, and the firmware must reprogram those devices with the
original guest memory allocation addresses.

This patch accumulates the fw_cfg select, skip and write operations of
ProcessCmdWritePointer() in a validated / condensed form, and turns them
into an ACPI S3 Boot Script fragment at the very end of
InstallQemuFwCfgTables().

Laszlo Ersek 9965cbd424 OvmfPkg/AcpiPlatformDxe: implement the QEMU_LOADER_WRITE_POINTER command
The QEMU_LOADER_WRITE_POINTER command instructs the firmware to write the
address of a field within a previously allocated/downloaded fw_cfg blob
into another (writeable) fw_cfg file at a specific offset.

Put differently, QEMU_LOADER_WRITE_POINTER propagates, to QEMU, the
address that QEMU_LOADER_ALLOCATE placed the designated fw_cfg blob at, as
adjusted for the given field inside the allocated blob.

The implementation is similar to that of QEMU_LOADER_ADD_POINTER. Since
here we "patch" a pointer object in "fw_cfg file space", not guest memory
space, we utilize the QemuFwCfgSkipBytes() and QemuFwCfgWriteBytes() APIs
completed in commit range 465663e9f128..7fcb73541299.

An interesting aspect is that QEMU_LOADER_WRITE_POINTER creates a
host-level reference to a guest memory location. Therefore, if we fail to
process the linker/loader script for any reason, we have to clear out
those references first, before we release the guest memory allocations in
response to the error.

Laszlo Ersek a316d7ac91 OvmfPkg/SmmControl2Dxe: select broadcast SMI if available
When writing to IO port 0xB2 (ICH9_APM_CNT), QEMU by default injects an
SMI only on the VCPU that is writing the port. This has exposed corner
cases and strange behavior with edk2 code, which generally expects a
software SMI to affect all CPUs at once. We've experienced instability
despite the fact that OVMF sets PcdCpuSmmApSyncTimeout and
PcdCpuSmmSyncMode differently from the UefiCpuPkg defaults, such that they
match QEMU's unicast SMIs better. (Refer to edk2 commits 9b1e378811 and
bb0f18b0bce6.)

Using the new fw_cfg-based SMI feature negotiation in QEMU (see commits
50de920b372b "hw/isa/lpc_ich9: add SMI feature negotiation via fw_cfg" and
5ce45c7a2b15 "hw/isa/lpc_ich9: add broadcast SMI feature"), we can ask
QEMU to broadcast SMIs. Extensive testing from earlier proves that
broadcast SMIs are only reliable if we use the UefiCpuPkg defaults for the
above PCDs. With those settings however, the broadcast is very reliable --
the most reliable configuration encountered thus far.

Therefore negotiate broadcast SMIs with QEMU, and if the negotiation is
successful, dynamically revert the PCDs to the UefiCpuPkg defaults.

Setting the PCDs in this module is safe:

- only PiSmmCpuDxeSmm consumes them,

- PiSmmCpuDxeSmm is a DXE_SMM_DRIVER, launched by the SMM_CORE
  (MdeModulePkg/Core/PiSmmCore/PiSmmCore.inf),

- the SMM_CORE is launched by the SMM IPL runtime DXE driver
  (MdeModulePkg/Core/PiSmmCore/PiSmmIpl.inf),

- the SMM IPL has a DEPEX on EFI_SMM_CONTROL2_PROTOCOL,

- OvmfPkg/SmmControl2Dxe produces that protocol.

The end result is that PiSmmCpuDxeSmm cannot be dispatched before
SmmControl2Dxe installs EFI_SMM_CONTROL2_PROTOCOL and returns from its
entry point. Hence we can set the PCD's consumed by PiSmmCpuDxeSmm in
SmmControl2Dxe.

Introduce the new public API QemuFwCfgSkipBytes(), for advancing over
bytes in the selected firmware configuration item without transferring
data between the item and the caller.

When the DMA interface is available (the common case), the operation is
instantaneous. As a fallback, provide a loop of chunked reads into a small
stack-allocated scratch buffer.

This patch enables OvmfPkg/QemuFwCfgLib to overwrite part of a writeable
fw_cfg file, which will be particularly useful for the upcoming
QEMU_LOADER_WRITE_POINTER command in OvmfPkg/AcpiPlatformDxe.

Laszlo Ersek d055601ea7 OvmfPkg/QemuFwCfgLib: generalize InternalQemuFwCfgDmaBytes() to SKIP op
The fw_cfg DMA interface provides a simple method to skip over bytes in an
fw_cfg blob before reading or writing more bytes.
InternalQemuFwCfgDmaBytes() can support it easily, we just have to expose
the Control parameter more flexibly than the current "Write" BOOLEAN.

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

Bhupesh Sharma 6e5e544f22 OvmfPkg: Install BGRT ACPI table
While debugging OS for ACPI BGRT support (especially on VMs),
it is very useful to have the EFI firmware (OVMF in most cases
which use Tianocore) to export the ACPI BGRT table.

This patch tries to add this support in OvmfPkg.

Tested this patch in the following environments:

1. On both RHEL7.3 and Fedora-25 VM guests running on a Fedora-24 Host:
   - Ensured that the BGRT logo is properly prepared and
     can be viewed with user-space tools (like 'Gwenview' on KDE,
     for example):

     $ file /sys/firmware/acpi/bgrt/image
     /sys/firmware/acpi/bgrt/image: PC bitmap, Windows 3.x format, 193 x
     58 x 24

2. On a Windows-10 VM Guest running on a Fedora-24 Host:
   - Ensured that the BGRT ACPI table is properly prepared and can be
     read with freeware tool like FirmwareTablesView:

     ==================================================
     Signature         : BGRT
     Firmware Provider : ACPI
     Length            : 56
     Revision          : 1

     Description       :
     ==================================================

Note from Laszlo Ersek <lersek@redhat.com>: without the BGRT ACPI table,
Windows 8 and Windows 10 first clear the screen, then display a blue,
slanted Windows picture above the rotating white boot animation. With the
BGRT ACPI table, Windows 8 and Windows 10 don't clear the screen, the blue
Windows image is not displayed, and the rotating white boot animation is
shown between the firmware's original TianoCore boot splash and (optional)
"Start boot option" progress bar.

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.

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

It is safe to read the fw_cfg item QemuFwCfgItemSmpCpuCount (0x0005). It
was added to QEMU in 2008 as key FW_CFG_NB_CPUS, in commit 905fdcb5264c
("Add common keys to firmware configuration"). Even if the key is

QemuFwCfgRead16() will return 0, and then we stick with the current

Laszlo Ersek 103b12cec5 OvmfPkg/PlatformBootManagerLib: guard the definition of ARRAY_SIZE
In one of the next patches, we'll introduce ARRAY_SIZE in
"MdePkg/Include/Base.h". In order to proceed in small steps, make the
module-local definition of ARRAY_SIZE conditional. This way the
introduction of the macro under MdePkg will silently switch this module
over (after which we can remove the module-local definition completely).

XenConsoleSerialPortLib is a BASE type library instance, without being
restricted to UEFI client modules. (For example, the
"ArmVirtPkg/ArmVirtXen.dsc" platform builds this library instance into
"ArmVirtPkg/PrePi/ArmVirtPrePiUniCoreRelocatable.inf", which is a SEC type
module.) For such library instances, including <Uefi/UefiBaseType.h> is
not right.

Laszlo Ersek 4dd8787a20 OvmfPkg/QemuVideoDxe: upgrade VERBOSE debug messages to INFO
In commit 5b2291f956 ("OvmfPkg: QemuVideoDxe uses
MdeModulePkg/FrameBufferLib"), QemuVideoDxe was rebased to
FrameBufferBltLib.

The FrameBufferBltLib instance added in commit b1ca386074
("MdeModulePkg: Add FrameBufferBltLib library instance") logs many
messages on the VERBOSE level; for example, a normal boot with OVMF can
produce 500+ "VideoFill" messages, dependent on the progress bar, when the
VERBOSE bit is set in PcdDebugPrintErrorLevel. While FrameBufferBltLib is
certainly allowed to log such messages on the VERBOSE level, we should
separate those frequent messages from the (infrequent) ones produced by
QemuVideoDxe itself.

QemuVideoDxe logs VERBOSE messages in three locations (in two functions)
at the moment. All of them are infrequent: both QemuVideoBochsModeSetup()
and InstallVbeShim() are called from QemuVideoControllerDriverStart(),
that is, when a device is bound. Upgrade these messages to INFO level, so
that VERBOSE can be disabled in PcdDebugPrintErrorLevel -- perhaps
selectively for OvmfPkg/QemuVideoDxe -- without hiding these infrequent
messages.

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.

The basic idea is that VGPU_DEV abstracts the virtio GPU device, while the
single VGPU_GOP that we intend to support at this point stands for "head"
(aka "scanout") #0.

For now, the Virtio Device Protocol is only used for driver binding; no
actual virtio operations are done yet. Similarly, we use a "dummy" GOP
GUID and protocol structure (a plain UINT8 object) for now, so that
GOP-consuming drivers don't look at what we produce just yet.

The driver is a bit different from the other virtio device drivers written
thus far:

- It implements the GetControllerName() member of the Component Name 2
  Protocol. (Formatting helpful names is recommended by UEFI.) As a "best
  effort", we format the PCI BDF into the name (a PCI backend is not
  guaranteed by VIRTIO_DEVICE_PROTOCOL). It should provide a more friendly
  experience in the shell and elsewhere.

- This driver seeks to support all RemainingDevicePath cases:
  - NULL: produce all (= one) child handles (= VGPU_GOP heads) at once,
  - End of Device Path Node: produce no child handles,
  - specific ACPI ADR Node: check if it's supportable, and produce it
    (only one specific child controller is supported).
  This is one of the reasons for separating VGPU_GOP from VGPU_DEV.

The driver is a hybrid driver: it produces both child handles (one, to be
exact), but also installs a structure (VGPU_DEV) directly on the VirtIo
controller handle, using gEfiCallerIdGuid as protocol GUID. This is a
trick I've seen elsewhere in edk2 (for example, TerminalDxe), and it is
necessary for the following reason:

In EFI_COMPONENT_NAME2_PROTOCOL.GetControllerName(), we must be able to
"cast down" a VirtIo ControllerHandle to our own private data structure
(VGPU_DEV). That's only possible if we install the structure directly on
the VirtIo ControllerHandle (thereby rendering the driver a hybrid
driver), because a child controller with our GOP implementation on it may
not exist / be passed in there.

Laszlo Ersek 76569ca855 OvmfPkg/Virtio10Dxe: don't bind virtio-vga
Commit 9399f68ae3 ("OvmfPkg: Virtio10Dxe: non-transitional driver for
virtio-1.0 PCI devices") created a "competition" between Virtio10Dxe and
QemuVideoDxe for virtio-vga devices. The binding order between these
drivers is unspecified, and the wrong order effectively breaks commit
94210dc95e ("OvmfPkg: QemuVideoDxe: add virtio-vga support").

Thus, never bind virtio-vga in Virtio10Dxe; QemuVideoDxe provides better
compatibility for guest OSes that insist on inheriting a linear
framebuffer. Users who prefer the VirtIo GPU interface at boot time should
specify virtio-gpu-pci, which is exactly virtio-vga, minus the VGA
compatibility (such as the framebuffer).

Laszlo Ersek 442c2ab81e OvmfPkg/QemuVideoDxe: don't incorrectly bind virtio-gpu-pci
The PCI (Vendor ID, Device ID) pair (0x1af4, 0x1050) stands for both the
virtio-vga and the virtio-gpu-pci device models of QEMU. They differ in
two things:

- the former has a VGA-compatibility linear framebuffer on top of the
  latter,

- the former has PCI_CLASS_DISPLAY_VGA device class, while the latter has
  PCI_CLASS_DISPLAY_OTHER.

In commit 94210dc95e ("OvmfPkg: QemuVideoDxe: add virtio-vga support"),
we enabled QemuVideoDxe to drive virtio-vga simply by adding its (Vendor
ID, Device ID) pair to gQemuVideoCardList. This change inadvertently
allowed QemuVideoDxe to bind virtio-gpu-pci, which it cannot drive though.

Restrict QemuVideoDxe to PCI_CLASS_DISPLAY_VGA, in order to exclude
virtio-gpu-pci. For the other cards that QemuVideoDxe drives, this makes
no difference. (Note that OvmfPkg's PlatformBootManagerLib instance has
always only added PCI_CLASS_DISPLAY_VGA devices to ConOut; see
DetectAndPreparePlatformPciDevicePath().)

Cinnamon Shia a6d594c5fa OvmfPkg: use StatusCode Router and Handler from MdeModulePkg
In the Platform Init v1.4a spec,
- Volume 1 "4.7 Status Code Service" defines the
  EFI_PEI_SERVICES.ReportStatusCode() service,
- Volume 1 "6.3.5 Status Code PPI (Optional)" defines the
  EFI_PEI_PROGRESS_CODE_PPI (equivalent to the above),
- Volume 2 "14.2 Status Code Runtime Protocol" defines the
  EFI_STATUS_CODE_PROTOCOL.

These allow PEIMs and DXE (and later) modules to report status codes.

Currently OvmfPkg uses modules from under
"IntelFrameworkModulePkg/Universal/StatusCode/", which produce the above
abstractions (PPI and PROTOCOL) directly, and write the status codes, as
they are reported, to the serial port or to a memory buffer. This is
called "handling" the status codes.

In the Platform Init v1.4a spec,
- Volume 3 "7.2.2 Report Status Code Handler PPI" defines
  EFI_PEI_RSC_HANDLER_PPI,
- Volume 3 "7.2.1 Report Status Code Handler Protocol" defines
  EFI_RSC_HANDLER_PROTOCOL.

These allow several PEIMs and runtime DXE drivers to register callbacks
for status code handling.

MdeModulePkg offers a PEIM under
"MdeModulePkg/Universal/ReportStatusCodeRouter/Pei" that produces both
EFI_PEI_PROGRESS_CODE_PPI and EFI_PEI_RSC_HANDLER_PPI, and a runtime DXE
driver under "MdeModulePkg/Universal/ReportStatusCodeRouter/RuntimeDxe"
that produces both EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL.

MdeModulePkg also offers status code handler modules under
MdeModulePkg/Universal/StatusCodeHandler/ that depend on
EFI_PEI_RSC_HANDLER_PPI and EFI_RSC_HANDLER_PROTOCOL, respectively.

The StatusCodeHandler modules register themselves with
ReportStatusCodeRouter through EFI_PEI_RSC_HANDLER_PPI /
EFI_RSC_HANDLER_PROTOCOL. When another module reports a status code
through EFI_PEI_PROGRESS_CODE_PPI / EFI_STATUS_CODE_PROTOCOL, it reaches
the phase-matching ReportStatusCodeRouter module first, which in turn
passes the status code to the pre-registered, phase-matching
StatusCodeHandler module.

The status code handling in the StatusCodeHandler modules is identical to
the one currently provided by the IntelFrameworkModulePkg modules. Replace
the IntelFrameworkModulePkg modules with the MdeModulePkg ones, so we can
decrease our dependency on IntelFrameworkModulePkg.

Laszlo Ersek f0e6a56a9a OvmfPkg: include UefiCpuPkg/CpuMpPei
In the next patch we're going to put EFI_PEI_MP_SERVICES_PPI to use.

CpuMpPei uses the following PCDs from gUefiCpuPkgTokenSpaceGuid, beyond
those already used by CpuDxe:

- PcdCpuMicrocodePatchAddress and PcdCpuMicrocodePatchRegionSize: these
  control whether CpuMpPei performs microcode update. If the region size
  is zero, then the microcode update is skipped. UefiCpuPkg.dec sets the
  region size to zero by default, which is appropriate for OVMF.

- PcdCpuApLoopMode and PcdCpuApTargetCstate: the former controls how
  CpuMpPei puts the APs to sleep: 1 -- HLT, 2 -- MWAIT, 3 -- busy wait
  (with PAUSE). The latter PCD is only relevant if the former PCD is 2
  (MWAIT). In order to be consistent with SeaBIOS and with CpuDxe itself,
  we choose HLT. That's the default set by UefiCpuPkg.dec.

Furthermore, although CpuMpPei could consume SecPeiCpuExceptionHandlerLib
technically, it is supposed to consume PeiCpuExceptionHandlerLib. See:

- http://thread.gmane.org/gmane.comp.bios.edk2.devel/12703

- git commit a81abf1616 ("UefiCpuPkg/ExceptionLib: Import
  PeiCpuExceptionHandlerLib module"), part of the series linked above.

Jeff recommended to resolve CpuExceptionHandlerLib to
PeiCpuExceptionHandlerLib for all PEIMs:

- http://thread.gmane.org/gmane.comp.bios.edk2.devel/14471/focus=14477

Since at the moment we have no resolution in place that would cover this
for PEIMs (from either [LibraryClasses] or [LibraryClasses.common.PEIM]),
it's easy to do.

Laszlo Ersek 8aba40b792 OvmfPkg: add PciHotPlugInitDxe
After IncompatiblePciDeviceSupportDxe, this is another small driver /
protocol implementation that tweaks the behavior of the PCI bus driver in
edk2.

The protocol is specified in the Platform Init Spec v1.4a, Volume 5,
Chapter 12.6 "PCI Hot Plug PCI Initialization Protocol". This
implementation steers the PCI bus driver to reserve the following
resources ("padding") for each PCI bus, in addition to the BARs of the
devices on that PCI bus:
- 2MB of 64-bit non-prefetchable MMIO aperture,
- 512B of IO port space.

The goal is to reserve room for devices hot-plugged at runtime even if the
bridge receiving the device is empty at boot time.

The 2MB MMIO size is inspired by SeaBIOS. The 512B IO port size is
actually only 1/8th of the PCI spec mandated reservation, but the
specified size of 4096 has proved wasteful (given the limited size of our
IO port space -- see commit bba734ab4c). Especially on Q35, where every
PCIe root port and downstream port qualifies as a separate bridge (capable
of accepting a single device).

Test results for this patch:
- regardless of our request for 64-bit MMIO reservation, it is downgraded
  to 32-bit,
- although we request 512B alignment for the IO port space reservation,
  the next upstream bridge rounds it up to 4096B.

- DXEFV's base address or size changed (historical),
- DXEFV's FvNameGuid changed,
- the FILE_GUID of the pointed-to binary changed,
- the referenced binary is no longer built into the firmware.

For example, multiple such "EFI Internal Shell" boot options can coexist.
They technically differ from each other, but may not describe any built-in
shell binary exactly. Such options can accumulate in a varstore over time,
and while they remain generally bootable (thanks to the efforts of
BmGetFileBufferByFvFilePath()), they look bad.

Filter out any stale options.

This functionality is not added to QemuBootOrderLib, because it is
independent from QEMU and fw_cfg.

- The EFI_FIRMWARE_VOLUME_HEADER.ExtHeaderOffset field is set to a nonzero
  value, pointing after EFI_FIRMWARE_VOLUME_HEADER itself (although not
  directly, see below).

- An EFI_FIRMWARE_VOLUME_EXT_HEADER object is created at the pointed-to
  address. This object is not followed by any
  EFI_FIRMWARE_VOLUME_EXT_ENTRY (= extension) entries, so it only
  specifies the Name GUID for the firmware volume.

  The EFI_FIRMWARE_VOLUME_EXT_HEADER for each firmware volume can be found
  in the Build directory as a separate file (20 bytes in size):

  Build/Ovmf*/*_GCC*/FV/*.ext

- The new data consume 48 bytes in the following volumes: SECFV,
  FVMAIN_COMPACT, DXEFV. They comprise:

  - 16 padding bytes,

  - EFI_FFS_FILE_HEADER2 (8 bytes in total: no Name and ExtendedSize
    fields, and Type=EFI_FV_FILETYPE_FFS_PAD),

  - EFI_FIRMWARE_VOLUME_EXT_HEADER (20 bytes, see above),

  - 4 padding bytes.

  (The initial 16 padding bytes and the EFI_FFS_FILE_HEADER2 structure are
  the reason why EFI_FIRMWARE_VOLUME_HEADER.ExtHeaderOffset does not point
  immediately past EFI_FIRMWARE_VOLUME_HEADER.)

  The sizes of the firmware volumes don't change, only their internal
  usages grow by 48 bytes. I verified that the statements and calculations
  in "OvmfPkg/DecomprScratchEnd.fdf.inc" are unaffected and remain valid.

- The new data consume 0 bytes in PEIFV. This is because PEIFV has enough
  internal padding at the moment to accomodate the above structures
  without a growth in usage.

In the future, firmware volumes can be identified by Name GUID (Fv(...)
device path nodes), rather than memory location (MemoryMapped(...) device
path nodes). This is supposed to improve stability for persistent device
paths that refer to FFS files; for example, UEFI boot options.

Gary Lin da2369d21d OvmfPkg/PlatformBootManagerLib: Connect the Xen drivers before loading NvVars
When OVMF tried to load the file-based NvVars, it checked all the PCI
instances and connected the drivers to the mass storage device. However,
Xen registered its PCI device with a special class id (0xFF80), so
ConnectRecursivelyIfPciMassStorage() couldn't recognize it and skipped the
driver connecting for Xen PCI devices. In the end, the Xen block device
wasn't initialized until EfiBootManagerConnectAll() was called, and it's
already too late to load NvVars.

This commit connects the Xen drivers in ConnectRecursivelyIfPciMassStorage()
so that Xen can use the file-based NvVars.

* Introduce XenDetected() to cache the result of Xen detection instead
  of relying on PcdPciDisableBusEnumeration.

* Cosmetic changes

Laszlo Ersek a3cd5cd5f6 OvmfPkg/PlatformBootManagerLib: rebase boot logo display to BootLogoLib
In the course of porting OvmfPkg to the MdeModulePkg BDS, commit
817fb3ac2a

  OvmfPkg/PlatformBootManagerLib: Add EnableQuietBoot & DisableQuietBoot

open-coded the EnableQuietBoot() function (and its dependencies / friends)
from IntelFrameworkModulePkg BDS.

This code duplication can be avoided; the functionality is available from
the following three libraries in MdeModulePkg:

- BootLogoLib: provides the BootLogoEnableLogo() function. It does not
  provide the internal ConvertBmpToGopBlt() function -- that one is
  delegated to ImageDecoderLib (function DecodeImage()).

- ImageDecoderLib: a general library that registers decoder plugins for
  specific image formats, and provides the generic DecodeImage() on top.

- BmpImageDecoderLib: one of said decoder plugins, for handling BMP images
  (which is the format of our logo).

In this patch, we revert 817fb3ac2a, and atomically incorporate the
above libraries. This is inspired by Nt32Pkg commit 859e75c4fc42:

  Nt32Pkg: Use BootLogoLib for logo and progress bar drawing.

Laszlo Ersek 855743f717 OvmfPkg: prevent 64-bit MMIO BAR degradation if there is no CSM
According to edk2 commit

  "MdeModulePkg/PciBus: do not improperly degrade resource"

and to the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL definition in the
Platform Init 1.4a specification, a platform can provide such a protocol
in order to influence the PCI resource allocation performed by the PCI Bus
driver.

In particular it is possible instruct the PCI Bus driver, with a
"wildcard" hint, to allocate the 64-bit MMIO BARs of a device in 64-bit
address space, regardless of whether the device features an option ROM.

(By default, the PCI Bus driver considers an option ROM reason enough for
allocating the 64-bit MMIO BARs in 32-bit address space. It cannot know if
BDS will launch a legacy boot option, and under legacy boot, a legacy BIOS
binary from a combined option ROM could be dispatched, and fail to access
MMIO BARs in 64-bit address space.)

In platform code we can ascertain whether a CSM is present or not. If not,
then legacy BIOS binaries in option ROMs can't be dispatched, hence the
BAR degradation is detrimental, and we should prevent it. This is expected
to conserve the 32-bit address space for 32-bit MMIO BARs.

The driver added in this patch could be simplified based on the following
facts:

- In the Ia32 build, the 64-bit MMIO aperture is always zero-size, hence
  the driver will exit immediately. Therefore the driver could be omitted
  from the Ia32 build.

- In the Ia32X64 and X64 builds, the driver could be omitted if CSM_ENABLE
  was defined (because in that case the degradation would be justified).
  On the other hand, if CSM_ENABLE was undefined, then the driver could be
  included, and it could provide the hint unconditionally (without looking
  for the Legacy BIOS protocol).

These short-cuts are not taken because they would increase the differences
between the OVMF DSC/FDF files. If we can manage without extreme
complexity, we should use dynamic logic (vs. build time configuration),
plus keep conditional compilation to a minimum.

- The Xen community has embraced the new BDS. Examples:

  49effaf26e OvmfPkg/PciHostBridgeLib: Scan for root bridges when

- OVMF doesn't build with "-D USE_OLD_BDS -D HTTP_BOOT_ENABLE" anyway, as
  NetworkPkg/HttpBootDxe now requires UefiBootManagerLib:

Laszlo Ersek 1466b76f93 OvmfPkg: determine PMBA value dependent on host bridge device ID
In this patch, the AcpiTimerLib instances, ResetSystemLib, and PlatformPei
are modified together in order to keep VMs functional across a bisection:
they all must agree on the PMBA value used.

ResetSystemLib must not use dynamic PCDs. With SOURCE_DEBUG_ENABLE, it
gets linked into the debug agent, therefore the same restrictions apply to
it as to BaseRomAcpiTimerLib. Luckily, AcpiPmControl() is only used for
powering off the virtual machine, thus the extra cost of a PCI config
space read, compared to a PcdGet16(), should be negligible.

This is the patch that moves the PMBA to IO port 0x0600 on Q35 in
practice.

The ResetSystemLib change is easiest to verify with the "reset -s" command
in the UEFI shell (which goes through gRT->ResetSystem() and, in OVMF,
PcAtChipsetPkg/KbcResetDxe).

Laszlo Ersek b97af6d42b OvmfPkg: introduce ICH9_PMBASE_VALUE
According to the ICH9 spec, PMBASE "provides 128 bytes of I/O space for
ACPI, GPIO, and TCO logic. This is placed on a 128-byte boundary".

On the Q35 machine type of QEMU, our current PMBASE setting of 0xB000 is
the only thing that prevents us from lowering the base of the PCI IO port
aperture from 0xC000. (The base must be aligned to 0x1000 due to PCI
bridge requirements.)

By moving our PMBASE to 0x0600 (moving the register block to
0x0600..0x067F inclusive), which is also what SeaBIOS uses on Q35, we will
be able to lower the PCI IO port aperture base to 0x6000 (the next IO port
under it being taken by the "vmport" device, at fixed 0x5658), while
steering clear of other QEMU devices.

On PIIX4, freeing up the 0x1000 IO ports at 0xB000 wouldn't help much,
because the 0xA000 block right below it is occupied by unmovable devices
(see <https://bugzilla.redhat.com/show_bug.cgi?id=1333238#c19> for
details).

Doing this for Q35 only has two more benefits:
- It won't interfere with Xen guests,
- The Q35 machine type with the smallest version number is "pc-q35-2.4",
  which is guaranteed to have an ACPI generator. This matters because the
  ACPI tables (FACP, DSDT) have to reflect the PM base address that we
  program.

In the next patches, we'll differentiate the PMBA IO port address that we
program on PIIX4 vs. Q35.

Normally we'd just turn PcdAcpiPmBaseAddress into a dynamic PCD. However,
because we need this value in BaseRomAcpiTimerLib too (which cannot access
RAM and dynamic PCDs), it must remain a build time constant. We will
introduce its Q35 counterpart later.

Gary Lin 14b2ebc30c OvmfPkg/PlatformBootManagerLib: Postpone the shell registration
We currently register the shell before creating the boot options for
the block devices and the network devices, so the boot manager boots
into the internal shell if the user doesn't specify the boot order.
However, Xen doesn't support fw_cfg, so there is no way to change the
boot order with the external command, and the firmware will always
boot into the internal shell if the user doesn't interfere the boot
process.

This patch postpones the shell registration after MdeModulePkg/BDS
creates all the boot options for the block and network devices, so
that firmware will try to boot the block/network devices first.

Laszlo Ersek 1da7616649 OvmfPkg/QemuBootOrderLib: adapt Q35 SATA PMPN to UEFI spec Mantis 1353
On the Q35 machine type of QEMU, there is no port multiplier connected to
the on-board SATA controller. Therefore the AtaAtapiPassThru driver update

Adapt the translation from OpenFirmware in QemuBootOrderLib.

(Note: QemuBootOrderLib is deprecated at this point (see USE_OLD_BDS in
the DSC files), but until we remove it, it should be kept in sync with
QemuNewBootOrderLib.)

Hao Wu 259d87146b OvmfPkg: Modify FDF/DSC files for RamDiskDxe's adding NFIT report feature
The RamDiskDxe driver in MdeModulePkg now will use EFI_ACPI_TABLE_PROTOCOL
and EFI_ACPI_SDT_PROTOCOL during reporting RAM disks to NVDIMM Firmware
Interface Table (NFIT).

A Pcd 'PcdInstallAcpiSdtProtocol' controls whether the
EFI_ACPI_SDT_PROTOCOL will be produced. Its default value is set to FALSE
in MdeModulePkg. To make the NFIT reporting feature working properly under
OVMF, the patch will set the Pcd to TRUE in OVMF DSC files.

Also, the RamDiskDxe driver will sometimes report a NVDIMM Root Device
using ASL code which is put in a Secondary System Description Table (SSDT)
according to the ACPI 6.1 spec.

Locating the SSDT requires modifying the [Rule.Common.DXE_DRIVER] field in
OVMF FDF files.

While a runtime OS is never booted with SMM unlocked (because the SMM IPL

> Boot signal
> SmmInstallProtocolInterface: [EfiSmmReadyToLockProtocol] 0
> Patch page table start ...
> Patch page table done!
> SMM IPL locked SMRAM window

), we shouldn't allow UEFI drivers and applications either to mess with
SMM just because S3 is disabled. So install
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL in PlatformBdsInit() unconditionally.

Laszlo Ersek 70017e4461 OvmfPkg: PlatformBdsLib: lock down SMM in PlatformBdsInit()
OVMF's PlatformBdsLib currently makes SMM vulnerable to the following
attack:

(1) a malicious guest OS copies a UEFI driver module to the EFI system
    partition,

(2) the OS adds the driver as a Driver#### option, and references it from
    DriverOrder,

(3) at next boot, the BdsEntry() function in
    "IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c" processes
    Driver#### and DriverOrder between the calls to PlatformBdsInit() and
    PlatformBdsPolicyBehavior(),

(4) OVMF locks down SMM only in PlatformBdsPolicyBehavior(), hence the
    driver runs with SMM unlocked.

The BdsEntry() function of the MdeModulePkg BDS driver (in file
"MdeModulePkg/Universal/BdsDxe/BdsEntry.c") recommends to "Signal
ReadyToLock event" in PlatformBootManagerBeforeConsole() -- which
corresponds to PlatformBdsInit() --, not in
PlatformBootManagerAfterConsole() -- which corresponds to
PlatformBdsPolicyBehavior().

Albeit an independent question, but it's worth mentioning: this patch also
brings OvmfPkg's PlatformBdsInit() closer to ArmVirtPkg's. Namely, the
latter signals End-of-Dxe in PlatformBdsInit() already.

Laszlo Ersek eccc28bfcb OvmfPkg: 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.

Laszlo Ersek 9399f68ae3 OvmfPkg: Virtio10Dxe: non-transitional driver for virtio-1.0 PCI devices
This driver implements the VIRTIO_DEVICE_PROTOCOL for non-transitional PCI
devices, based on the virtio-1.0 specification (csprd05). Non-transitional
means that it only binds QEMU's virtio-xxx-pci devices that receive the
",disable-legacy=on,disable-modern=off" properties on the QEMU command
line. These devices have distinct PCI Device IDs from those that are bound
by VirtioPciDeviceDxe.

The central abstraction of this driver is the VIRTIO_1_0_CONFIG type. It
is practically a "fat pointer" to a register block. The pointed-to
register block
- may or may not exist (the latter being mostly useful for virtio-1.0
  devices that have no device-specific registers),
- lives in one of the device's BARs,
- lives in an IO or MMIO BAR,
- lives at an offset relative to the BAR start,
- has its size also maintained.

Such VIRTIO_1_0_CONFIG "fat pointers" (i.e., the locations of the register
blocks) are parsed from vendor capabilities that reside in the device's
standard PCI capabilities list (in PCI config space).

Laszlo Ersek c6e2d064ab OvmfPkg: VirtioNetDxe: adapt virtio-net packet header size to virtio-1.0
In virtio-0.9.5, the size of the virtio-net packet header depends on
whether the VIRTIO_NET_F_MRG_RXBUF feature is negotiated -- the
"num_buffers" field is only appended to the header if the feature is
negotiated.

Since we never negotiate this feature, VirtioNetDxe never allocates room
for the "num_buffers" field.

With virtio-1.0, the "num_buffers" field is always there (although it
doesn't carry useful information without VIRTIO_NET_F_MRG_RXBUF). Adapt
the buffers that depend on the virtio-net header size (otherwise we have
skewed / truncated packets).

Laszlo Ersek bc8fde6f62 OvmfPkg: VIRTIO_DEVICE_PROTOCOL: widen the Features bitmap to 64 bits
The virtio-1.0 spec widens the Features bitmap to 64 bits. Modify the
declarations of the GetDeviceFeatures() and SetGuestFeatures() protocol
member functions accordingly.

Normally, a protocol cannot be changed in incompatible ways if the GUID
stays the same; however, we've always been extremely clear that
VIRTIO_DEVICE_PROTOCOL is internal to edk2. See for example the top of
"OvmfPkg/Include/Protocol/VirtioDevice.h".

In this patch, all producers and consumers of the GetDeviceFeatures() and
SetGuestFeatures() protocol members are updated.

The drivers that currently produce these members are "legacy" drivers (in
virtio-1.0 terminology), and they cannot (and will not) handle feature
bits above BIT31. Therefore their conversion is only for compatibility
with the modified protocol interface. The consumers will be responsible
for checking the VIRTIO_DEVICE_PROTOCOL.Revision field, and for not
passing feature bits that these backends cannot handle.

The VirtioMmioGetDeviceFeatures() implementation stores the result of an
MmioRead32() call with normal assignment, so it needs no change beyond
adapting its prototype.

Laszlo Ersek 7e5b1b670c OvmfPkg: PlatformPei: determine the 64-bit PCI host aperture for X64 DXE
The main observation about the 64-bit PCI host aperture is that it is the
highest part of the useful address space. It impacts the top of the GCD
memory space map, and, consequently, our maximum address width calculation
for the CPU HOB too.

Thus, modify the GetFirstNonAddress() function to consider the following
areas above the high RAM, while calculating the first non-address (i.e.,
the highest inclusive address, plus one):

- the memory hotplug area (optional, the size comes from QEMU),

- the 64-bit PCI host aperture (we set a default size).

While computing the first non-address, capture the base and the size of
the 64-bit PCI host aperture at once in PCDs, since they are natural parts
of the calculation.

(Similarly to how PcdPciMmio32* are not rewritten on the S3 resume path
(see the InitializePlatform() -> MemMapInitialization() condition), nor
are PcdPciMmio64*. Only the core PciHostBridgeDxe driver consumes them,
through our PciHostBridgeLib instance.)

Set 32GB as the default size for the aperture. Issue#59 mentions the
NVIDIA Tesla K80 as an assignable device. According to nvidia.com, these
cards may have 24GB of memory (probably 16GB + 8GB BARs).

As a strictly experimental feature, the user can specify the size of the
aperture (in MB) as well, with the QEMU option

  -fw_cfg name=opt/ovmf/X-PciMmio64Mb,string=65536

The "X-" prefix follows the QEMU tradition (spelled "x-" there), meaning
that the property is experimental, unstable, and might go away any time.
Gerd has proposed heuristics for sizing the aperture automatically (based
on 1GB page support and PCPU address width), but such should be delayed to
a later patch (which may very well back out "X-PciMmio64Mb" then).

For "everyday" guests, the 32GB default for the aperture size shouldn't
impact the PEI memory demand (the size of the page tables that the DXE IPL
PEIM builds). Namely, we've never reported narrower than 36-bit addresses;
the DXE IPL PEIM has always built page tables for 64GB at least.

For the aperture to bump the address width above 36 bits, either the guest
must have quite a bit of memory itself (in which case the additional PEI
memory demand shouldn't matter), or the user must specify a large aperture
manually with "X-PciMmio64Mb" (and then he or she is also responsible for
giving enough RAM to the VM, to satisfy the PEI memory demand).

Laszlo Ersek d537168063 OvmfPkg: PlatformPei: factor out GetFirstNonAddress()
Factor out the expression that is currently the basis of the address width
calculation into a standalone function. In the next patches we'll raise
the return value under certain circumstances.

Laszlo Ersek 8f35eb92c4 OvmfPkg: AcpiPlatformDxe: enable PCI IO and MMIO while fetching QEMU tables
Now that the previous patches ensure that we can access all PCI devices in
AcpiPlatformDxe, we can enable IO and MMIO decoding for all of them while
we contact QEMU for the ACPI tables. See more details in the patch titled:

  OvmfPkg: introduce gRootBridgesConnectedEventGroupGuid

In particular, this patch will prevent the bug when the 64-bit MMIO
aperture is completely missing from QEMU's _CRS, and consequently Linux
rejects 64-bit BARs with the error message

  pci 0000:00:03.0: can't claim BAR 4 [mem 0x800000000-0x8007fffff 64bit
                    pref]: no compatible bridge window

Laszlo Ersek b6bc800d5a OvmfPkg: AcpiPlatformDxe: when PCI is enabled, wait for Platform BDS's cue
This patch doesn't change the behavior of AcpiPlatformDxe when
PcdPciDisableBusEnumeration is TRUE -- that is, when the driver runs on
Xen (OvmfPkg and ArmVirtPkg both), or when the driver runs on QEMU as part
of ArmVirtPkg but no PCI host bridge was found by VirtFdtDxe. In these
cases the driver continues to install the ACPI tables immediately.

However, when PcdPciDisableBusEnumeration is FALSE (i.e., when the driver
runs on QEMU as part of OVMF, or as part of ArmVirtPkg and VirtFdtDxe
finds a PCI host bridge), we now delay the ACPI table download from QEMU.
We wait until the Platform BDS tells us that root bridges have been
connected, and PciIo instances are available.

The explanation is in the patch titled

Laszlo Ersek 9116c9c5d8 OvmfPkg: introduce gRootBridgesConnectedEventGroupGuid
QEMU's ACPI table generator can only create meaningful _CRS objects --
apertures -- for the root buses if all of the PCI devices behind those
buses are actively decoding their IO and MMIO resources, at the time of
the firmware fetching the "etc/table-loader" fw_cfg file. This is not a
QEMU error; QEMU follows the definition of BARs (which are meaningless
when decoding is disabled).

Currently we hook up AcpiPlatformDxe to the PCI Bus driver's
gEfiPciEnumerationCompleteProtocolGuid cue. Unfortunately, when the PCI
Bus driver installs this protocol, it's *still* not the right time for
fetching "etc/table-loader": although resources have been allocated and
BARs have been programmed with them, the PCI Bus driver has also cleared
IO and MMIO decoding in the command registers of the devices.

Furthermore, we couldn't reenable IO and MMIO decoding temporarily in our
gEfiPciEnumerationCompleteProtocolGuid callback even if we wanted to,
because at that time the PCI Bus driver has not produced PciIo instances
yet.

Our Platform BDSes are responsible for connecting the root bridges, hence
they know exactly when the PciIo instances become available -- not when
PCI enumeration completes (signaled by the above protocol), but when the
ConnectController() calls return.

This is when our Platform BDSes should explicitly cue in AcpiPlatformDxe.
Then AcpiPlatformDxe can temporarily enable IO and MMIO decoding for all
devices, while it contacts QEMU for the ACPI payload.

This patch introduces the event group GUID that we'll use for unleashing
AcpiPlatformDxe from our Platform BDSes.
