Hi,
I build MARSS with DRAMSim using single atom core and it runs fine. I need
to implement 3 cores with 3 threads. I applied the below commands
1- scons -Q debug=2 -j3 c=3
dramsim=/home/ashafik/NEW_20140724/marwdram/DRAMSim2
2- change the configuration of atom_core
# Atom core
atom_core:
description: Single Atom Core configuration
min_contexts: 1
max_contexts: 3 # The number of cores ... Is that right ?
cores: # The order in which core is defined is used to assign
# the cores in a machine
- type: atom
name_prefix: atom_
option:
threads: 3
caches:
- type: l1_128K
name_prefix: L1_I_
insts: $NUMCORES # Per core L1-I cache
- type: l1_128K
name_prefix: L1_D_
insts: $NUMCORES # Per core L1-D cache
- type: l2_2M
name_prefix: L2_
insts: 1 # Shared L2 config
memory:
- type: dram_cont
name_prefix: MEM_
insts: 1 # Single DRAM controller
option:
latency: 50 # In nano seconds
interconnects:
- type: p2p
# '$' sign is used to map matching instances like:
# core_0, L1_I_0
connections:
- core_$: I
L1_I_$: UPPER
- core_$: D
L1_D_$: UPPER
- L1_I_0: LOWER
L2_0: UPPER
- L1_D_0: LOWER
L2_0: UPPER2
- L2_0: LOWER
MEM_0: UPPER
3- run the Qemu command
qemu/qemu-system-x86_64 -simconfig
/home/ashafik/NEW_20140724/marwdram/marss.dramsim/config/default.conf -hda
/home/ashafik/full_system_images/ubuntu-natty.qcow2 &
4- run the simconfig command in VM console
(qemu) simconfig -run -stats test1 -machine atom_core
5- get the below error. am I missing something?
VNC server running on `127.0.0.1:5900'
::ERROR::Can't find 'atom_core' machine generator.
qemu-system-x86_64: ptlsim/build/sim/machine.cpp:532: void
MachineBuilder::setup_machine(BaseMachine&, const char*): Assertion `gen'
failed.
Thanks and BR,
Ahmed
