Hi All,

Attempting to Read SPIBAR 0x10 from BUS 0 Dev 1F Func 5

>>
ScSpiBar0 = MmioRead32 (SpiInstance->PchSpiBase +
PCI_BASE_ADDRESSREG_OFFSET) & 0xFFFFF000;
>>

The above code is throwing exception

PchSpiBase at 0xC00FD000
!!!! X64 Exception Type - 0E(#PF - Page-Fault)  CPU Apic ID - 00000000 !!!!
ExceptionData - 0000000000000000  I:0 R:0 U:0 W:0 P:0 PK:0 SS:0 SGX:0
RIP  - 00000000771903D0, CS  - 0000000000000038, RFLAGS - 0000000000010046

>From the shell the value at offset 0x10 is 0xFE010000

Any clues on why the processor is throwing exception while accessing the
value PchSpiBase+0x10 ?

Thanks
