Per my bisection: nasm broke the parsing of the "--" end-of-options
delimiter in commit 55568c1193df ("nasm: scan the command line twice",
2016-10-03), part of the nasm-2.13 release. The parsing remains broken in
at least nasm-2.15.03. The (invalid) error message is: "more than one
input file specified". I've filed the following ticket for upstream nasm
(and ndisasm): <https://bugzilla.nasm.us/show_bug.cgi?id=3392829>.
Since the delimiter is not necessary in practice (due to $STEM being
"VbeShim", i.e., not starting with a hyphen), simply remove the delimiter.
Tested by enabling DEBUG in "VbeShim.asm", running the script, building
OVMF, booting Windows 7, and checking the firmware log (debug console).

Prevent stack underrun in the event of a timer interrupt storm in
LocalApicTimerDxe and 8254TimerDxe interrupt handlers by using the
helper functions provided by NestedInterruptTplLib.
This fixes the same problem as addressed in commit 239b50a86
("OvmfPkg: End timer interrupt later to avoid stack overflow under
load"), but does so without breaking nested timer interrupts.

UEFI requires us to support nested interrupts, but provides no way for
an interrupt handler to call RestoreTPL() without implicitly
re-enabling interrupts. In a virtual machine, it is possible for a
large burst of interrupts to arrive. We must prevent such a burst
from leading to stack underrun, while continuing to allow nested
interrupts to occur.
This can be achieved by allowing, when provably safe to do so, an
inner interrupt handler to return from the interrupt without restoring
the TPL and with interrupts remaining disabled after IRET, with the
deferred call to RestoreTPL() then being issued from the outer
interrupt handler. This is necessarily messy and involves direct
manipulation of the interrupt stack frame, and so should not be
implemented as open-coded logic within each interrupt handler.
Add the Nested Interrupt TPL Library (NestedInterruptTplLib) to
provide helper functions that can be used by nested interrupt handlers
in place of RaiseTPL()/RestoreTPL().
Example call tree for a timer interrupt occurring at TPL_APPLICATION
with a nested timer interrupt that makes its own call to RestoreTPL():
outer TimerInterruptHandler()
InterruptedTPL == TPL_APPLICATION
...
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
gBS->RestoreTPL (TPL_APPLICATION);
EnableInterrupts();
dispatch a TPL_CALLBACK event
gEfiCurrentTpl = TPL_CALLBACK;
nested timer interrupt occurs
inner TimerInterruptHandler()
InterruptedTPL == TPL_CALLBACK
...
IsrState->InProgressRestoreTPL = TPL_CALLBACK;
gBS->RestoreTPL (TPL_CALLBACK);
EnableInterrupts();
DisableInterrupts();
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
IRET re-enables interrupts
... finish dispatching TPL_CALLBACK events ...
gEfiCurrentTpl = TPL_APPLICATION;
DisableInterrupts();
IsrState->InProgressRestoreTPL = 0;
sees IsrState->DeferredRestoreTPL == FALSE and returns
IRET re-enables interrupts
Example call tree for a timer interrupt occurring at TPL_APPLICATION
with a nested timer interrupt that defers its call to RestoreTPL() to
the outer instance of the interrupt handler:
outer TimerInterruptHandler()
InterruptedTPL == TPL_APPLICATION
...
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
gBS->RestoreTPL (TPL_APPLICATION);
EnableInterrupts();
dispatch a TPL_CALLBACK event
... finish dispatching TPL_CALLBACK events ...
gEfiCurrentTpl = TPL_APPLICATION;
nested timer interrupt occurs
inner TimerInterruptHandler()
InterruptedTPL == TPL_APPLICATION;
...
sees InterruptedTPL == IsrState->InProgressRestoreTPL
IsrState->DeferredRestoreTPL = TRUE;
DisableInterruptsOnIret();
IRET returns without re-enabling interrupts
DisableInterrupts();
IsrState->InProgressRestoreTPL = 0;
sees IsrState->DeferredRestoreTPL == TRUE and loops
IsrState->InProgressRestoreTPL = TPL_APPLICATION;
gBS->RestoreTPL (TPL_APPLICATION); <-- deferred call

Deferring the EOI until after the call to RestoreTPL() means that any
callbacks invoked by RestoreTPL() will run with timer interrupt
delivery disabled. If any such callbacks themselves rely on timers to
implement timeout loops, then the callbacks will get stuck in an
infinite loop from which the system will never recover.
This reverts commit 239b50a86 ("OvmfPkg: End timer interrupt later to
avoid stack overflow under load").

Introduce page table pool mechanism for smm page table to simplify
page table memory management and protection. This mechanism has been
used in DxeIpl. The basic idea is to allocate a bunch of continuous
pages of memory in advance, and all future page tables consumption
will happen in those pool instead of system memory.
Since we have centralized page tables, we only need to mark all page
table pools as RO, instead of searching page table memory layer by
layer in smm page table. Once current page table pool has been used
up, another memory pool will be allocated and the new pool will also
be set as RO if current page table memory has been marked as RO.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4172
TDVF once accepts memory only by BSP. To improve the boot performance
this patch introduce the multi-core accpet memory. Multi-core means
BSP and APs work together to accept memory.
TDVF leverages mailbox to wake up APs. It is not enabled in MpInitLib
(Which requires SIPI). So multi-core accept memory cannot leverages
MpInitLib to coordinate BSP and APs to work together.
So TDVF split the accept memory into 2 phases.
- AcceptMemoryForAPsStack:
BSP accepts a small piece of memory which is then used by APs to setup
stack. We assign a 16KB stack for each AP. So a td-guest with 256 vCPU
requires 255*16KB = 4080KB.
- AcceptMemory:
After above small piece of memory is accepted, BSP commands APs to
accept memory by sending AcceptPages command in td-mailbox. Together
with the command and accpet-function, the APsStack address is send
as well. APs then set the stack and jump to accept-function to accept
memory.
AcceptMemoryForAPsStack accepts as small memory as possible and then jump
to AcceptMemory. It fully takes advantage of BSP/APs to work together.
After accept memory is done, the memory region for APsStack is not used
anymore. It can be used as other private memory. Because accept-memory
is in the very beginning of boot process and it will not impact other
phases.

During the finalization of Mp initialization before booting into the OS,
depending on whether Mwait is supported or not, AsmRelocateApLoop
places Aps in MWAIT-loop or HLT-loop.
Since paging is necessary for long mode, the original implementation of
moving APs to 32-bit was to disable paging to ensure that the booting
does not crash.
The current modification creates a page table in reserved memory,
avoiding switching modes and reclaiming memory by OS. This modification
is only for 64 bit mode.
More specifically, we keep the AMD logic as the original code flow,
extract and update the Intel-related code, where the APs would stay
in 64-bit, and run in a Mwait or Hlt loop until the OS wake them up.

Add condition to return success if mUartCount is greater
than zero in SerialPortInitialize() to avoid filling mUartInfo
with the same hob data when SerialPortInitialize() is called
multiple times. Also add proper conditions in SerialPortRead
function to read the data properly from multiple UART's.

For some use cases, Redfish host interface table relies on
the certain EFI protocols installation at the driver connection.
Redfish host interface DXE driver is not able to build the
SMBIOS type 42h record at driver entry point. This patch adds
the mechanism in Redfish host interface DXE driver to listen
to EFI protocol installed by platform library that indicates
the necessary information is ready for building SMBIOS 42h
record.

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.
0x3C = (VAR_IN_DELETED_TRANSITION & VAR_ADDED) & VAR_DELETED
or
0x3D = VAR_ADDED & VAR_DELETED
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)
and removed the following invalid states:
VAR_IN_DELETED_TRANSITION
VAR_DELETED

Allow object to specify the name of processor and processor container
nodes and the UID of processor containers.
This allows these to be more accurately referenced from other tables.
For example for the _PSL method or the UID in the APMT table.
The UID and Name for processor container may be different as if the
intention is to set names as the corresponding affinity level the UID
may need to be different if there are multiple levels of containers.
