[edk2-devel] Transition from DxeIpl to DxeCoreLoad

[edk2-devel] Transition from DxeIpl to DxeCoreLoad

[Alireza Banejad]

Hello everyone,
I am building the wilsonCity Rvp From the whitleyLake package inside
edk2-platforms. unfortunately i wasn't able to get the debug running
even though I tried everything but that isn't my problem right now
since I use POST codes on each part of code and check to see if the
codes are displayed on the motherboard. my main problem is I put a
post code right before dxeipl to see if it reaches this point:
IoWrite8(0x80,0x7b);
Status = TempPtr.DxeIpl->Entry (
TempPtr.DxeIpl,
&PrivateData.Ps,
PrivateData.HobList
);
and so the motherboard shows me 0x7b but it doen't go inside the
DxeloadCore function since I put a Post code at the very beginning of
this function and its still stuck on the 0x7b code:
EFI_STATUS
EFIAPI
DxeLoadCore (
IN CONST EFI_DXE_IPL_PPI *This,
IN EFI_PEI_SERVICES **PeiServices,
IN EFI_PEI_HOB_POINTERS HobList
)
{
...
//
// if in S3 Resume, restore configure
//
IoWrite8(0x80,0x3a);
BootMode = GetBootModeHob ();
IoWrite8(0x80,0x22);
...
 I dont have any better debug approaches to check the stack or
registers that is why i can only send POST codes as evidence that
execution has reached to that point. I dont know why it doesn't
execute the DxeLoadCore properly and I assume the CPU halts since it
just stays stuck on the previous post code from before calling DxeIpl
(I mean 0x7b). I also checked if any arguments being passed to
TempPtr.DxeIpl->Entry are NULL but it seemed none were NULL.
Thanks,
Alireza
