Hi Samuel,
You can include a ram disk by taking part of the
physical memory and placing a ram disk there. For example for a ram disk
in linux (provided you had a ram disk driver is the kernel), you could
add something like:
self.ramdisk = PhysicalMemory(range =
AddrRange(Addr('128MB'), size = '128MB'), file='/path/to/ramdisk.img')
and assuming you only specified 128MB of DRAM the upper 128MB would be
used for ramdisk.
The easiest thing to do is an ELF file.

Barrelfish [1] to ARMv7 modeled by gem5. As I'm new to using gem5, I
have some simple questions to start with.

the kernel or can I somehow specify, where the ramdisk should be loaded
into memory in the script? As far as I see it, with gem5 one doesn't
need/have a bootloader where such things could be specified.
