Currently, the PE/COFF conversion routines in GenFw add a so-called
NB10 CodeView debug record to the image, and update the associated
directory entry in the PE/COFF optional header to contain its relative
virtual address (RVA) and size.
However, there are two levels of indirection at work here: the actual
NB10 CodeView record (which is simply a magic number and some unused
data fields followed by the NUL terminated filename) is emitted
separately, and a separate descriptor is emitted that identifies the
NB10 CodeView record as type EFI_IMAGE_DEBUG_TYPE_CODEVIEW, and records
its size. The directory entry in the PE/COFF optional header should
refer to this intermediate descriptor's address and size only, but
the WriteDebug## () routines in GenFw erroneously record the size of
both the descriptor and the NB10 CodeView record.
This problem was exposed by commit e4129b0e58 ("BaseTools: Update
GenFw to clear unused debug entry generated by VS tool chain",
2017-06-19), and GenFw now crashes when it attempts to iterate over
what it thinks are multiple intermediate descriptors for different
kinds of debug data embedded in the image.
The error is understandable, given that both are carved out of the
same file space allocation, but this is really an implementation detail
of GenFw, and is not required. (Note that the intermediate descriptor
does not require a RVA and so it does not even need to be inside a
section)
So omit the size of the NB10 CodeView record from the size recorded
in the optional header.

In one of the next patches we'll turn PcdQ35TsegMbytes into a dynamic PCD,

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".

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

Commit 7b1dc6c569 'ArmVirtPkg: switch to generic ResetSystemRuntimeDxe'
replaced all references in ArmVirtPkg to the deprecated ResetRuntimeDxe
from EmbeddedPkg with the well maintained generic alternative that lives
in MdeModulePkg.
However, as it turns out, the generic driver has a dependency on the
library class ReportStatusCodeLib, whose default resolution is an
implementation that is not safe for use at runtime, resulting in crashes
when trying to invoke it from the OS.
Since we have no use for status codes in any of the ArmVirtPkg
platforms, let's replace all resolutions with a common one to the NULL
implementation.

Given that all platforms use an implementation of EfiResetSystemLib [as
consumed by the ResetRuntimeDxe in EmbeddedPkg that we are replacing]
which is unlikely to be depended upon by out of tree platforms, let's
simply modify this library into an implementation of ResetSystemLib
instead [which is what the generic driver in MdeModulePkg consumes]
This does mean we need to update all clients at the same time, which
is why all changes are part of the same patch.
As before, warm reset and platform specific reset are mapped onto
cold reset (which is the only thing PSCI implements, at least the
version we depend on). The new library function EnterS3WithImmediateWake()
is left unimplemented, as permitted by the ResetSystemLib library class.
