Yuanhao,
Sorry. I are missing the following updating.

Please ignore my last comments ! :-)

Yuanhao，
Have you verirfed whether APs could be waken-up from ApInHltLoop state or not?
Thanks!

Ray,
If you chooses assembly solution, you'd better to consider stack adjust to
follow calling convention. Otherwise, it may break some debugger tools to do
call stack trace.

Ray,
Could we add one API (like InitializeApicTimerEx) to intialize CPU local APCI
with additional parameter to indicate if interrupt is to be enabled or not?
Just like HPE's solution.

Please correct the commit message which confused me.
It should be "Update the PcdCpuStackGuard to support PcdsPatchableInModule,
PcdsDynamci and PcdsDynamciEx ... ..."
Thanks!

On 32bit protectd mode, is there any impact if PcdCpuStackGuard is set to TRUE?
Even thers is no page table enabling at that time.

What's CR2 value in Exception dump information？It holds the actual address

ExceptionData - P:0 means no page transition in page table.

I agree that the AP function should do something, but I'm hoping to get this
initial implementation committed first.

Hi，Rebecca
I'd like to give two comments on this patch.
1, I don't think there are more than one MP services instances installed
reuirement on one system. X86 platform installed one MP service instance even
on mutiple-sockets system.
For ARM platform, is there any requirement to handle
You may try to enlarger stmm_ns_comm_buf_size in Optee to check if it could
solve ASSERT issue.

OVMF did a similare change on Time Driver, please refer to
https://github.com/tianocore/edk2/commit/239b50a863704f7960525799eda82de061c7c458
I do not think this will be apply for ArmPkg/TimerDxe.
If one real issue happened on platform, it seems that interrupt was reenabled
by reigstered

For former caller, they could still keep as is to call the old API in
MdeModulePkg. I think Ray's design is compatible change for existing code.
Only when the existing code wants to remove the dependency on MdeModuelPkg,
they could migrate to the new API in baselib.
I agree with one split-API
Making baselib implementation depend on MemoryAllocationLib (indirectly on Pei

Add this parameter and make this parameter is optional,

ImageBase was saved in DR2 to help HOST debugger to locate the image base more
easily, even though the HOST debugger could find the image base through
searching the DOS image signagure.
The reason choosing DR1 and DR2 to save PDB & ImageBase contexts is just
implementation only. And

Ray,
Yes. You are right. Acutally, x64 IDT table cannot work correctly on protected
mode. :-)
But for GDT location, I agree it should be located under 4G space to support AP
mode changing. But we could allocate room under 4G for GDT table directly in
CpuDxe.
Thanks,
Jeff
