Hi,
In X86 system, by default, APIC range in Gem5 starts from 0xFEC00000 and
Local APIC starts from 0xFEE00000. As a result I cannot create a single
memory controller of more than 3GB starting from 0 physical address. Is it
possible to move APIC range to start from 16GB starting address rather
than 0xFEE00000 (4GB) starting address please?
I modified FSConfig but linux fails to boot:
io_apic = X86IntelMPIOAPIC(
id = numCPUs,
version = 0x11,
enable = True,
address = 0xfec00000) <== Modified this to 0xA3D70A3
Or is it possible to disable APIC? I set False in above but still linux
fails.
Thanks.
Ahmad
