The RIP values are mostly consistent across these page faults:

     32 000000007FF8AD50
     32 000000007FF8AD82
      1 000000007FF8AE6C
      1 000000007FFA9501

That is, one PF for each CPU at 000000007FF8AD50, and one PF for each
CPU at 000000007FF8AD82.

Furthermore, if we check the invalid addresses (CR2 -- Page Fault Linear
Address) of these faults, we see that the instruction 000000007FF8AD50
runs in a loop body that iterates, in steps of 0x08, from 0x00 to 0xF8.
The same applies to the instruction at 000000007FF8AD82.

Now, if we check

  objdump -S Build/Ovmf3264/NOOPT_GCC5/X64/UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm/DEBUG/PiSmmCpuDxeSmm.debug

then that confirms that relative offset 0x1E3E5 (= EntryPoint-ImageBase
= 000000007FFA63E5-000000007FF88000) is indeed the entry point:

> 000000000001e3e5 <_ModuleEntryPoint>:
> EFIAPI
> _ModuleEntryPoint (
>   IN EFI_HANDLE        ImageHandle,
>   IN EFI_SYSTEM_TABLE  *SystemTable

>    1e3e6:       48 89 e5                mov    %rsp,%rbp
>    1e3e9:       48 83 ec 30             sub    $0x30,%rsp

>    1e3f1:       48 89 55 18             mov    %rdx,0x18(%rbp)
>   EFI_STATUS                 Status;
>   EFI_LOADED_IMAGE_PROTOCOL  *LoadedImage;

Thus we can investigate both faulting instruction pointers too:

(a) 000000007FF8AD50 - 000000007FF88000 = 2D50

(b) 000000007FF8AD82 - 000000007FF88000 = 2D82

And then objdump reports:

This comes directly from commit
725acd0b9cc047b20a1b9379e46f05d3ebcf485e, and the problem is most
probably that "mCpuHotPlugData.SmBase" is NULL.

And that's indeed very possible, after commit
725acd0b9cc047b20a1b9379e46f05d3ebcf485e:

If GetSmBase() returns NULL, the code will now print "PiCpuSmmEntry:
gSmmBaseHobGuid not found" -- which is indeed what we find in the log --,
but there is nothing to set "mCpuHotPlugData.SmBase" to non-NULL, before
we try to write through it.

(b)

    gSmmCpuPrivate->CpuSaveState[Index]     = (VOID *)(mCpuHotPlugData.SmBase[Index] + SMRAM_SAVE_STATE_MAP_OFFSET);
    2d70:       48 8b 15 39 b3 02 00    mov    0x2b339(%rip),%rdx        # 2e0b0 <mCpuHotPlugData+0x10>

    2d7f:       48 01 d0                add    %rdx,%rax
    2d82:       48 8b 00                mov    (%rax),%rax           <------------------ FAULT
    2d85:       48 8d 90 00 fc 00 00    lea    0xfc00(%rax),%rdx
    2d8c:       48 8b 05 35 b3 02 00    mov    0x2b335(%rip),%rax        # 2e0c8 <gSmmCpuPrivate>
    2d93:       48 8b 48 28             mov    0x28(%rax),%rcx
    2d97:       48 8b 45 d8             mov    -0x28(%rbp),%rax
    2d9b:       48 c1 e0 03             shl    $0x3,%rax
    2d9f:       48 01 c8                add    %rcx,%rax
    2da2:       48 89 10                mov    %rdx,(%rax)

I'm going to ignore this crash site for now, and theorize more on crash
site (a):

I claim that this NULL pointer dereference (write) has been in place
*ever since* commit 725acd0b9cc0 ("UefiCpuPkg: Avoid assuming only one
smmbasehob", 2023-12-12). That is, I claim / theorize that GetSmBase()
*always* returns a NULL pointer in OVMF SMM; i.e., it's not
"conditional" behavior from GetSmBase().

Instead, the only reason we've not seen it is that we have a *short
loop* counting up (= writing upwards) from address 0 in increments of 8
bytes, and the number of iterations is the possible VCPU count. Because
we have usually very few VCPUs, the overwritten area at the start of
page#0 is pretty small.

But if we have, say, 32 possible VCPUs, then we overwrite 32*8 == 256
bytes, and then the VBE Shim's check for "Int0x10->Segment == 0x0000"
fails. Because, if I count right, the "Int0x10->Segment" field of type
UINT16 starts at linear address 0x42.

We need to fix or revert commit 725acd0b9cc0 for the upcoming stable
release.
