OvmfPkg/PlatformInitLib: Fix integrity checking failed of NvVarStore
In the commit 4f173db8b4 "OvmfPkg/PlatformInitLib: Add functions for
EmuVariableNvStore", it introduced a PlatformValidateNvVarStore() function
for checking the integrity of NvVarStore.
In some cases when the VariableHeader->StartId is VARIABLE_DATA, the
VariableHeader->State is not just one of the four primary states:
VAR_IN_DELETED_TRANSITION, VAR_DELETED, VAR_HEADER_VALID_ONLY, VAR_ADDED.
The state may combined two or three states, e.g.
When the variable store has those variables, system booting/rebooting will
hangs in a ASSERT:
NvVarStore Variable header State was invalid.
ASSERT
/mnt/working/source_code-git/edk2/OvmfPkg/Library/PlatformInitLib/Platform.c(819):
((BOOLEAN)(0==1))
Adding more log to UpdateVariable() and PlatformValidateNvVarStore(), we
saw some variables which have 0x3C or 0x3D state in store.
e.g.
UpdateVariable(), VariableName=BootOrder
L1871, State=0000003F <-- VAR_ADDED
State &= VAR_DELETED=0000003D
FlushHobVariableToFlash(), VariableName=BootOrder
...
UpdateVariable(), VariableName=InitialAttemptOrder
L1977, State=0000003F
State &= VAR_IN_DELETED_TRANSITION=0000003E
L2376, State=0000003E
State &= VAR_DELETED=0000003C
FlushHobVariableToFlash(), VariableName=InitialAttemptOrder
...
UpdateVariable(), VariableName=ConIn
L1977, State=0000003F
State &= VAR_IN_DELETED_TRANSITION=0000003E
L2376, State=0000003E
State &= VAR_DELETED=0000003C
FlushHobVariableToFlash(), VariableName=ConIn
...
So, only allowing the four primary states is not enough. This patch changes
the falid states list (Follow Jiewen Yao's suggestion):
1. VAR_HEADER_VALID_ONLY (0x7F)
- Header added (*)
2. VAR_ADDED (0x3F)
- Header + data added
3. VAR_ADDED & VAR_IN_DELETED_TRANSITION (0x3E)
- marked as deleted, but still valid, before new data is added. (*)
4. VAR_ADDED & VAR_IN_DELETED_TRANSITION & VAR_DELETED (0x3C)
- deleted, after new data is added.
5. VAR_ADDED & VAR_DELETED (0x3D)
- deleted directly, without new data.
(*) means to support surprise shutdown.
And removed (VAR_IN_DELETED_TRANSITION) and (VAR_DELETED) because they are
invalid states.
v2:
Follow Jiewen Yao's suggestion to add the following valid states:
VAR_ADDED & VAR_DELETED (0x3D)
VAR_ADDED & VAR_IN_DELETED_TRANSITION (0x3E)
VAR_ADDED & VAR_IN_DELETED_TRANSITION & VAR_DELETED (0x3C)

be more general. So this patch rename:

A typical QEMU fw_cfg read bytes with IOMMU for td guest is that:
(QemuFwCfgReadBytes@QemuFwCfgLib.c is the example)
1) Allocate DMA Access buffer
2) Map actual data buffer
3) start the transfer and wait for the transfer to complete
4) Free DMA Access buffer
5) Un-map actual data buffer
In step 1/2, Private memories are allocated, converted to shared memories.
In Step 4/5 the shared memories are converted to private memories and
accepted again. The final step is to free the pages.
This is time-consuming and impacts td guest's boot perf (both direct boot
and grub boot) badly.
In a typical grub boot, there are about 5000 calls of page allocation and
private/share conversion. Most of page size is less than 32KB.
This patch allocates a memory region and initializes it into pieces of
memory with different sizes. A piece of such memory consists of 2 parts:
the first page is of private memory, and the other pages are shared
memory. This is to meet the layout of common buffer.
When allocating bounce buffer in IoMmuMap(), IoMmuAllocateBounceBuffer()
is called to allocate the buffer. Accordingly when freeing bounce buffer
in IoMmuUnmapWorker(), IoMmuFreeBounceBuffer() is called to free the
bounce buffer. CommonBuffer is allocated by IoMmuAllocateCommonBuffer
and accordingly freed by IoMmuFreeCommonBuffer.
This feature is tested in Intel TDX pre-production platform. It saves up
to hundreds of ms in a grub boot.

However, on 32-bit architectures, 'Alignment' is a 32-bit type, whereas
DescEnd is a 64-bit type, and so the resulting operation performed on

UefiCpuPkg: Bug fix in 5LPage handling
The hang (in the ASSERT) in DEBUG is not warranted as there are
legal configurations with CPUID(7).ECX[16](==LA57)=0
and with a physical address width of larger than 48 (like 52).
This is also supported by this code:
https://github.com/tianocore/edk2/blob/master/UefiCpuPkg/PiSmmCpuDxeSmm/X64/PageTbl.c#L221
There (as long as physical address width is smaller or equal to 52)
any address width above 48 will be reduced to 48 and the
system can and will work without 5LPaging.
The forced setting of LA57 in CR4 (in the absence of LA57 in CPUID(7).ECX)
is a spec violation and should not happen.
Hence the proposed fix
a) removes the assert.
b) only returns TRUE from Is5LevelPagingNeeded if 5LPaging is actually
supported by HW.

Due to more core count increasement, it's hard to reflect all APs
state via AP bitvector support in the register. Actually, SMM CPU
driver doesn't need to check each AP state to know all CPUs in SMI
or not, one alternative method is to check the SMM Delayed & Blocked
AP Count number:
APs in SMI + Blocked Count + Disabled Count >= All supported Aps
(code comments explained why can be > All supported Aps)
With above change, the returned value of "SmmRegSmmEnable" &
"SmmRegSmmDelayed" & "SmmRegSmmBlocked" from SmmCpuFeaturesLib
should be the AP count number within the existing CPU package.
For register that return the bitvector state, require
SmmCpuFeaturesGetSmmRegister() returns count number of all bit per
logical processor within the same package.
For register that return the AP count, require
SmmCpuFeaturesGetSmmRegister() returns the register value directly.
v3:
- Refine the coding style
v2:
- Rename "mPackageBspInfo" to "mPackageFirstThreadIndex"
- Clarify the expected value of "SmmRegSmmEnable" & "SmmRegSmmDelayed" &
"SmmRegSmmBlocked" returned from SmmCpuFeaturesLib.

EmulatorPkg/Win: Unload DLLs before reset
EmulatorPkg/Win calls LoadLibraryEx() when the corresponding DLL file
is found for each PEIM or DXE driver. The module entry point is
changed to point to the entry point from the DLL. This helps to
notify Visual Studio that a new windows module is loaded and
corresponding symbol parsing is performed for source level debugging.
But entry point from the DLL is only executed when the module is not
loaded by AddModHandle().
When reset happens, we need to clear the DLL loading so that in next
boot the module can be loaded again by AddModHandle().
Without this patch, source level debugging doesn't work after reset.
