Even though a copyright is present in the header file,
the leading '*' char prevents the Ecc tool from detecting it.
According to the edk2 coding specifcation, section 5.2.3

OvmfPkg/OvmfXen: Set PcdFSBClock
Update gEfiMdePkgTokenSpaceGuid.PcdFSBClock so it can have the correct
value when SecPeiDxeTimerLibCpu start to use it for the APIC timer.
Currently, nothing appear to use the value in PcdFSBClock before
XenPlatformPei had a chance to set it even though TimerLib is included
in modules run before XenPlatformPei.
XenPlatformPei doesn't use any of the functions that would use that
value. No other modules in the PEI phase seems to use the TimerLib
before PcdFSBClock is set. There are currently two other modules in
the PEI phase that needs the TimerLib:
- S3Resume2Pei, but only because LocalApicLib needs it, but nothing is
using the value from PcdFSBClock.
- CpuMpPei, but I believe it only runs after XenPlatformPei
Before the PEI phase, there's the SEC phase, and SecMain needs
TimerLib because of LocalApicLib. And it initialise the APIC timers
for the debug agent. But I don't think any of the DebugLib that
OvmfXen could use are actually using the *Delay functions in TimerLib,
and so would not use the value from PcdFSBClock which would be
uninitialised.
A simple runtime test showed that TimerLib doesn't use PcdFSBClock
value before it is set.

OvmfPkg/XenPlatformPei: Calibrate APIC timer frequency
Calculate the frequency of the APIC timer that Xen provides.
Even though the frequency is currently hard-coded, it isn't part of
the public ABI that Xen provides and thus may change at any time. OVMF
needs to determine the frequency by an other mean.
Fortunately, Xen provides a way to determines the frequency of the
TSC, so we can use TSC to calibrate the frequency of the APIC timer.
That information is found in the shared_info page which we map and
unmap once done (XenBusDxe is going to map the page somewhere else).
The shared_info page is mapped at the highest physical address allowed
as it doesn't need to be in the RAM, thus there's a call to update the
page table.
The calculated frequency is only logged in this patch, it will be used
in a following patch.

OvmfPkg/XenPlatformPei: Map extra physical address
Some information available in a Xen guest can be mapped anywhere in
the physical address space and they don't need to be backed by RAM.
For example, the shared info page.
While it's easier to put those pages anywhere, it is better to avoid
mapping it where the RAM is. It might split a nice 1G guest page table
into 4k pages and thus reducing performance of the guest when it
accesses its memory. Also mapping a page like the shared info page and
then unmapping it or mapping it somewhere else would leave a hole in
the RAM that the guest would propably not be able to use anymore.
So the patch introduces a new function which can be used to 1:1
mapping of guest physical memory above 4G during the PEI phase so we
can map the Xen shared pages outside of memory that can be used by
guest, and as high as possible.

1. Remove PEI instance(PeiCpuTimerLib).
PeiCpuTimerLib is currently designed to save time by getting CPU TSC
frequency from Hob. BaseCpuTimerLib is designed to calculate TSC frequency
by using CPUID[15h] each time.
The time it takes to find CpuCrystalFrequencyHob (about 2000ns) is much
longer than it takes to calculate TSC frequency with CPUID[15h] (about
450ns), which means using BaseCpuTimerLib to trigger a delay is more
accurate than using PeiCpuTimerLib, recommend to use BaseCpuTimerLib
instead of PeiCpuTimerLib.
2. Remove DXE instance(DxeCpuTimerLib).
DxeCpuTimerLib is designed to calculate TSC frequency with CPUID[15h] in
its constructor function, then save it in a global variable. For this
design, once the driver containing this instance is running, this
constructor function is called, it will take extra time to calculate TSC
frequency.
The time it takes to get TSC frequency from global variable is shorter
than it takes to calculate TSC frequency with CPUID[15h], but 450ns is a
short time, the impact on the platform is very limited.
In addition, in order to simplify the code, recommend to use
BaseCpuTimerLib instead of DxeCpuTimerLib.
I did some experiments on one server platform and collected following data:
1. Average time required to find CpuCrystalFrequencyHob: about 2000 ns.
2. Average time required to find the last Hob: about 2700 ns.
2. Average time required to calculate TSC frequency: about 450 ns.

MdePkg: use CpuPause() in CpuDeadLoop()
CpuPause() might allow the CPU to go into a lower power state
state while we spin.
On X86, CpuPause() executes a PAUSE instruction which the Intel
and AMD specs describe as follows:
Intel:
"PAUSE: An additional function of the PAUSE instruction is to reduce
the power consumed by a processor while executing a spin loop. A
processor can execute a spin-wait loop extremely quickly, causing the
processor to consume a lot of power while it waits for the resource it
is spinning on to become available. Inserting a pause instruction in a
spin-wait loop greatly reduces the processor?s power consumption."
AMD:
"PAUSE: Improves the performance of spin loops, by providing a hint to
the processor that the current code is in a spin loop. The processor
may use this to optimize power consumption while in the spin loop.
Architecturally, this instruction behaves like a NOP instruction."
On RISC-V and ARM64, CpuPause() executes a NOP, which is no worse than
the tight loop we have.

layout of the SMRAM regarding the SMM communication.

UefiCpuPkg/MpInitLib: avoid printing debug messages in AP
MpInitLib contains a function MicrocodeDetect() which is called by
all threads as an AP procedure.
Today this function contains below code:
if (CurrentRevision != LatestRevision) {
AcquireSpinLock(&CpuMpData->MpLock);
DEBUG ((
EFI_D_ERROR,
"Updated microcode signature [0x%08x] does not match \
loaded microcode signature [0x%08x]\n",
CurrentRevision, LatestRevision
));
ReleaseSpinLock(&CpuMpData->MpLock);
}
When the if-check is passed, the code may call into PEI services:
1. AcquireSpinLock
When the PcdSpinTimeout is not 0, TimerLib
GetPerformanceCounterProperties() is called. And some of the
TimerLib implementations would get the information cached in
HOB. But AP procedure cannot call PEI services to retrieve the
HOB list.
2. DEBUG
Certain DebugLib relies on ReportStatusCode services and the
ReportStatusCode PPI is retrieved through the PEI services.
DebugLibSerialPort should be used.
But when SerialPortLib is implemented to depend on PEI services,
even using DebugLibSerialPort can still cause AP calls PEI
services resulting hang.
It causes a lot of debugging effort on the platform side.
There are 2 options to fix the problem:
1. make sure platform DSC chooses the proper DebugLib and set the
PcdSpinTimeout to 0. So that AcquireSpinLock and DEBUG don't call
PEI services.
2. remove the AcquireSpinLock and DEBUG call from the procedure.
Option #2 is preferred because it's not practical to ask every
platform DSC to be written properly.
Following option #2, there are two sub-options:
2.A. Just remove the if-check.
2.B. Capture the CurrentRevision and ExpectedRevision in the memory
for each AP and print them together from BSP.
The patch follows option 2.B.

the CPU out of the SMI handler.
Meanwhile the CPU being ejected, waits around in its holding
area until it is context-switched out. Note that it is possible
that a slow CPU gets ejected before it reaches the wait loop.
However, this would never happen before it has executed the
"AllCpusInSync" loop in SmiRendezvous().
It can mean that an ejected CPU does not execute code after
that point but given that the CPU state will be destroyed by
QEMU, the missed cleanup is no great loss.

OvmfPkg/CpuHotplugSmm: add EjectCpu()
Add EjectCpu(), which handles the CPU ejection, and provides a holding
area for said CPUs. It is called via SmmCpuFeaturesRendezvousExit(),
at the tail end of the SMI handling.
Also UnplugCpus() now stashes QEMU Selectors of CPUs which need to be
ejected in CPU_HOT_EJECT_DATA.QemuSelectorMap. This is used by
EjectCpu() to identify CPUs marked for ejection.

OvmfPkg/SmmCpuFeaturesLib: call CPU hot-eject handler
Call the CPU hot-eject handler if one is installed. The condition for

The handler is called from SmmCpuFeaturesRendezvousExit(), which is
in-turn called at the tail-end of SmiRendezvous() after the BSP has
signalled an SMI exit via the "AllCpusInSync" loop.

OvmfPkg/SmmCpuFeaturesLib: init CPU ejection state
Init CPU_HOT_EJECT_DATA, which will be used to share CPU ejection
state between SmmCpuFeaturesLib (via PiSmmCpuDxeSmm) and CpuHotPlugSmm.
The init happens via SmmCpuFeaturesSmmRelocationComplete(), and so it
will run as part of the PiSmmCpuDxeSmm entry point function,
PiCpuSmmEntry(). Once inited, CPU_HOT_EJECT_DATA is exposed via
PcdCpuHotEjectDataAddress.
The CPU hot-eject handler (CPU_HOT_EJECT_DATA->Handler) is setup when
there is an ejection request via CpuHotplugSmm.

RedfishPkg/Library: RedfishLib
EDK2 port of DMTF libredfish project. We clone the necessary files
from open source project libredfish (https://github.com/DMTF/
libredfish) tag v1.0.0 and revise it to incorporate with edk2
firmware code base.
The reason of cloning the necessary files instead of using extern
submodule of libredfish project:
libredfish as a C library which is executed under Windows and
Linux. It could be binded with other programming languages such as
java and python. The library uses curl library as the communication service with Redfish, which is not easy to be abstracted and
replaced with EFI specific protocols (e.g. EFI_REST_EX_PROTOCOL or
payload encode/decode library) and EFI data types. We had the
conversation with DMTF community and they think edk2 is a firmware
solution but not the programming language,
therefore they rejected to have edk2 as a binding to libredfish.
According to above, we decide to clone the necessary files from
libredfish modify it to incorporate with edk2.

When Token points to mSmmStartupThisApToken, this routine is called
from SmmStartupThisAp() in non-blocking mode due to
PcdCpuSmmBlockStartupThisAp == FALSE.
In this case, caller wants to startup AP procedure in non-blocking
mode and cannot get the completion status from the Token because there
is no way to return the Token to caller from SmmStartupThisAp().
Caller needs to use its specific way to query the completion status.
There is no need to allocate a token for such case so the 3 overheads
can be avoided:
1. Call AllocateTokenBuffer() when there is no free token.
2. Get a free token from the token buffer.
3. Call ReleaseToken() in APHandler().
