Hi again,
Debugging seems to show that the TLB (vaddr) is not mapped to the physical
address. Below the output of the debugging:
==================================================
system.cpu.[tid:0]: Reading integer reg rsi (6) as 0x1970.
global: MOV_R_M : ld: The address is 0x1970

==================================================
Is this a bug in the current version of GEM5 where vaddr and paddr are not
being mapped?

Hi,
I am simulation an elf_i386 (32-bit x86) assembly code in SE mode. In my
assembly code, there is mov al, [esi] where esi is set to 0x1970.
When running my simulation I get the following error: "panic: Tried to read
unmapped address 0x1970."
I am initializing the DRAM with a binary disk image which contains my data that
the benchmark is expected to use. My GEM5 configuration includes the following:
======================================================
system.mem_mode = "timing"
system.mem_ranges = [AddrRange("8000MB")]
system.mem_ctrl = MemCtrl()
system.mem_ctrl.dram = DDR3_1600_8x8()
system.mem_ctrl[0].dram.image_file = 'binary_disk_image.bin'
system.mem_ctrl.dram.range = system.mem_ranges[0]
system.mem_ctrl.port = system.membus.mem_side_ports
======================================================
Any suggestion on how to resolve this error?
Thanks!
Alain
