[gem5-users] Getting segfault upon restoring a startup of arm-detailed Full system simulation

2015-11-09 Thread rahul shrivastava

Hi All,

I am checkpointing the startup for arm_detailed full system simulation
using hack_back_ckpt.rcS script. I can see that the checkpoint is created
successfully, but the restore fails with a seg fault.

: system.remote_gdb.listener: listening for remote gdb on port 7006
0: system.remote_gdb.listener: listening for remote gdb on port 7007
Switch at curTick count:1
info: Entering event queue @ 3748342464000.  Starting simulation...
Switched CPUS @ tick 3748342474000
switching cpus
info: Entering event queue @ 3748342474000.  Starting simulation...
Segmentation fault (core dumped)


The command to take checkpoint is
*M5_PATH=$(pwd)/.. ./build/ARM/gem5.fast configs/example/fs.py
--script=./configs/boot/hack_back_ckpt.rcS --cpu-type=arm_detailed --caches

The command to restore is
*M5_PATH=$(pwd)/.. ./build/ARM/gem5.fast configs/example/fs.py
--checkpoint-restore=1 --restore-with-cpu arm_detailed --caches -n 4

Am I giving some wrong option either while checkpointing or restoring?
Can you please help me here?

[gem5-users] Modelling command bus contention in DRAM controller

2015-11-09 Thread Prathap Kolakkampadath

Hello Users,

After closely looking at the doDRAMAccess() of dram controller
implementation in GEM5, i suspect that the current implementation may not
be taking in to account the command bus contention that could happen if
DRAM timing constraints take particular values.

For example in the below scenario, the queue has two closed requests one to
Bank1 and other to Bank2.

Request1@Bank1 (PRE-ACT-CAS) --> Request2@Bank2 (PRE-ACT-CAS)

Lets say tRP(8cycles), tRCD(8cycles), tCL(8cycles), and tRRD(8 cycles). In
this case ACT of R2 and CAS of R1 becomes active at the same time.
At this point one command needs to be delayed by one clock cycle. I don't
see how simulator is handling this?  If the simulator is handling this,
could someone please point me to the code snippet where this is handled.


Thanks,
Prathap

2015-11-09 Thread Andreas Hansson

Hi Prathap,

Command-bus contention is intentionally not modelled. The main reason for this 
is to keep the model performant. Moreover, in real devices the command bus is 
typically designed to _not_ be a bottleneck. Admittedly this choice could be 
reassessed if needed.

Hello Users,

After closely looking at the doDRAMAccess() of dram controller implementation 
in GEM5, i suspect that the current implementation may not be taking in to 
account the command bus contention that could happen if DRAM timing constraints 
take particular values.

For example in the below scenario, the queue has two closed requests one to 
Bank1 and other to Bank2.

Request1@Bank1 (PRE-ACT-CAS) --> Request2@Bank2 (PRE-ACT-CAS)

Lets say tRP(8cycles), tRCD(8cycles), tCL(8cycles), and tRRD(8 cycles). In this 
case ACT of R2 and CAS of R1 becomes active at the same time.
At this point one command needs to be delayed by one clock cycle. I don't see 
how simulator is handling this?  If the simulator is handling this, could 
someone please point me to the code snippet where this is handled.

Re: [gem5-users] Getting segfault upon restoring a startup of arm-detailed Full system simulation

2015-11-09 Thread rahul shrivastava

Hi All,

Some of the links suggested that checkpoint  should be created using the
default CPU and without any cache configuration as input. I made the
suggested changes in the  command, but it still, on restoring, I am getting
the same error. Following is the command that I am executing to  take
checkpoint

 ./build/ARM/gem5.fast configs/example/fs.py
--script=./configs/boot/hack_back_ckpt.rcS -n 4 --machine-type=VExpress_EMM
--kernel=../linux-linaro-tracking-gem5/vmlinux
--dtb-filename=../linux-linaro-tracking-gem5/arch/arm/boot/dts/vexpress-v2p-ca15-tc1-gem5_dvfs_per_core_4cpus.dtb
--disk-image=../disks/arm-ubuntu-natty-headless.img --cpu-clock=[1 GHz,750
MHz,500 MHz]


Could you please shed some light?

Rahul

Yes , Set the path to full_system_images/disks.

We have youtube video showing gem5 full system  installation for ARM .
Here is the link :

You can change it to X86 accordingly.

Re: [gem5-users] Modelling command bus contention in DRAM controller

2015-11-09 Thread Prathap Kolakkampadath

Hello Andreas,

One problem could be when there is a Miss request followed by a Hit
request. Taking the below example, initially queue has only one request
R1(Miss), as soon as the this request is selected there
is another request in the queue R2(Hit). Here CAS of R2 is ready and can be
issued right away in the next clock cycle. However,  i believe in the
simulator, while it computes the ready time of R1, it also recomputes the
next CAS that can be issued to other Banks. Thus the CAS of R2 can now be
issued only after the CAS of R1.  If i am right, this could be a problem?

Request1@Bank1 (PRE-ACT-CAS) --> Request2@Bank2 (CAS)

Thanks,
Prathap

You need to set the path to the fullsystem_disk_images where ever they are..
either set the M5_PATH
by doing something like
sudo echo “M5_PATH=/home/kassan/full_system_images/” >> ~./bashrc

or go into the syspaths.py  and at the end of the file you can insert the
