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
Ranga
