Re: [gem5-users] Unable to run script upon restoring from checkpoint

2018-08-03 Thread Woo L . L .

Hello there,

Problem solved. I did not set Cpu-Clock and Caches when I checkpoint the 
system, hence that’s why it throw the checkpoint in array.
Now I can successfully load the new script file and got the output needed.
Thanks.

Regards,
Elena

Thanks for the steps outlined. I have no issue with Step 1, because that’s 
exactly what I did. I just have problem with Step 2 because although it can 
restore from the checkpoint, it can’t read the new script file.

Best regards,
Elena

Oh, I was misunderstand your flow but here is what I am using and it works well

1) Create checkpoint using hack_back script, REMEMBER: not turning on m5_term 
when checkpoint is created because it can take terminal control which is 
supposed to release to your simulation when restoring. In the other word, let 
checkpoing is created without any interaction.

2) Restore from checkpoint as usual.

I though you may have problem with the step 1

Best,

Re: [gem5-users] Access stats during runtime

2018-05-06 Thread Woo L . L .

Yes, that was the intention - to access the host file from a Linux guest. 

I will study the Workload Automation more in depth as well as look into m5 
readfile.

Another way which I was thinking if it is possible to just get the required 
stats printed on the terminal, and send those information to a named pipe to be 
read by another terminal. Can I change the code to output certain stats on the 
terminal?

Thanks and regards,
Elena

Re: [gem5-users] Access stats during runtime

2018-05-06 Thread Woo L . L .

Hi Ciro,

It is the same issue, but there was no answer so I decided to ask a subset
of the question again in a different way.

I am interested in the CPU stats - system.cpu.committedInsts,
system.cpu.dcache.overall_misses, system.cpu.icache.overall_misses
These stats create a different profile for every different benchmark that
I run, and if an injected fault create an error which manifests as a
failure, the profile deviates. The idea is to have another core
functioning as a monitor and monitor these stats during runtime so that if
the stats value starts to deviate, the 2nd core can provide an interrupt
signal to the main core to halt the execution.

This is what I want to achieve in a general way. But I am stuck at
figuring how to access the stats file as it sits outside the disk image.
Thanks.

Elena

[gem5-users] Accessing Stats file from program running in FS mode

2018-05-01 Thread Woo L . L .

Hi all,

I am trying to set up a multicore environment where I have 1 core monitoring 
the stats file of another core. In order to do that, the monitoring core needs 
to access the stats file during simulation in FS mode. I have tried to open and 
read the stats file in the usual way (using a file pointer) but it was unable 
to do so. I understand the program was running from the disk image and hence, 
there is no way it could access files located outside the disk image. Is there 
any other way to obtain the stats from a running program?

I have also tried running two different programs where I set –n 2, but while it 
was able to run one program, there was an error ‘Permission denied’ when the 
other program was suppose to run. This was my command:

elena@elena-VirtualBox:~/RTS/gemfi/Sim$ ./build/X86/gem5.opt -r -d sim_out 
--debug-flags=FaultInjection ./configs/example/fs.py 
--script=./configs/boot/fft.rcS;./configs/boot/monitor.rcS -n 2 --caches 
--fi-in=input

Appreciate if anyone can tell me what went wrong.
Thanks.

Thank you.

Hi Jason,

I still don’t quite understand you. Please correct me if I am wrong - I assumed 
the host you meant the Ubuntu VM that I have installed. If I have one instance 
of gem5 running, how to I get another instance of gem5 running? I am trying to 
simulate a processor watching another processor in the same hardware, hence 
dist-gem5 would not really be applicable for me.

Thanks and regards,
Elena

Re: [gem5-users] Compiled Splash2x benchmarks segfault under FS with X86

2017-03-03 Thread Woo L . L .

Hi Wei Shu,

The issue with Glibc was also something I experienced before. The benchmark was 
able to run fine outside Gem5, but in Gem5 it produces that error. Someone 
thought me to recompile the benchmark in the image kernel loaded by Gem5. That 
step involves chroot to the image kernel and then recompile it from there. This 
is because your executable is running using same Linux kernel. Right now, 
assuming you are running on Ubuntu, your Linux kernel is 4.++ but Gem5 kernel 
is running on kernel version 2.++.

I believe once you solve the Glibc issue, the seg fault shouldn't appear 
anymore.

Hi Wei Shu,

I had similar problems when I tried running benchmarks from MiBench in FS mode 
using X86 architecture. The problem I think was because all the benchmarks were 
compiled statically. Once I recompiled those benchmarks dynamically, it solved 
the segmentation fault problem. 

Perhaps you can try to recompile your benchmarks dynamically. 
Thanks.

Dear Ferran,

Thank you so much for all your insights. 
I managed to re-compile the benchmark after chroot to the image.
I also solved the external libraries issues and managed to run it on both Gem5 
original and the other version of Gem5. 
Thanks so much!

Hi Elena,

I'm afraid I've never used this version of gem5, but if these calls to external 
libraries are calls to the m5 functions (such as m5_exit and
so) you will need to copy some files from gem5/util/m5 to the chroot as well. 
Think that, when you are inside a chroot, the shell you are using can "see" 
nothing outside the directory you have chrooted to, so anything the benchmark 
needs in order for it to be compiled has to be somewhere inside the chroot 
directory.

Cheers,
Ferran O.

Re: [gem5-users] Error with GLIBC 2.7 while trying to run C program in FS Mode

2017-02-03 Thread Woo L . L .

By the way,

The original benchmark which compiled successfully, when run with Gem5 in FS 
mode, the program was aborted. The error message received was:

Build/XC86/arch/xc86/tlb.cc.351: Fault XC86ISA::TLB::translate(RequestPtr, 
ThreadContext*, BaseTLB::Translation*, BaseTLB::Mode, bool&, bool): Assertion 
entry failed

--- BEGIN LIBC BACKTRACE --- shows issues with libpthread.so.0, libc.so.6, 
libpython2.7.so.1.0

So, in conclusion, although I was able to compile it in chroot, the program was 
not able to run in Gem5. 
Any thoughts on that?

Regards,
Elena

Hi Ferran,

I did as per your suggestions.
Initially, I was still facing with errors /bin/bash: /lib32/libc.so.6: version 
'GLIBC_2.11' not found as I am using the image that comes with GemFI (Gem5 with 
Fault Injection).

I redo the steps with the image downloaded from official gem5 web and I managed 
to chroot to the image. So, I recompile the original benchmark and it works 
fine. I also have a modified version of the benchmark source program where it 
includes calling external library. But when I tried to compile it with the 
following command:

Gcc -I/home/llw1n14/RTS/runtime/gemfi/ -L/home/llw1n14/RTS/runtime/gemfi/ 
qsort_small_fi.c -o qsort_small_fi -lm5

It gives me errors of being unable to read the header file (m5op.h) Do I need 
to mount the external library as well unto the image?

Thanks.

Hi Elena,

I assume that, in order to do full system simulation you have downloaded one of 
the images from the gem5 official web, right? What you have to do then is the 
following:

sudo su
cd /directory/where/your/image/is/located/

mkdir tmp_mnt

chroot ./tmp_mnt

Once you've done this, you will be chrooted to your image. Just navigate to 
your benchmark directory (/benchmarks in the case above) and compile as you 
would normally do. Once everything is done, use `exit` to go back to your 
system. Remember to unmount proc, dev and sys from your image once you've 
exited the chroot (`umount ./tmp_mnt/proc` and so on). If compilation went ok, 
then your benchmarks should work.

Re: [gem5-users] Error with GLIBC 2.7 while trying to run C program in FS Mode

2017-02-03 Thread Woo L . L .

Hi Ferran,

I did as per your suggestions.
Initially, I was still facing with errors /bin/bash: /lib32/libc.so.6: version 
'GLIBC_2.11' not found as I am using the image that comes with GemFI (Gem5 with 
Fault Injection).

I redo the steps with the image downloaded from official gem5 web and I managed 
to chroot to the image. So, I recompile the original benchmark and it works 
fine. I also have a modified version of the benchmark source program where it 
includes calling external library. But when I tried to compile it with the 
following command:

Gcc -I/home/llw1n14/RTS/runtime/gemfi/ -L/home/llw1n14/RTS/runtime/gemfi/ 
qsort_small_fi.c -o qsort_small_fi -lm5

It gives me errors of being unable to read the header file (m5op.h)
Do I need to mount the external library as well unto the image?

Thanks.
Elena

Hi Elena,

I assume that, in order to do full system simulation you have downloaded one of 
the images from the gem5 official web, right? What you have to do then is the 
following:

sudo su
cd /directory/where/your/image/is/located/

mkdir tmp_mnt

mount -o loop,offset=32256 x86root.img ./tmp_mnt # assuming your 
image is called x86root.img
mkdir -p ./tmp_mnt/benchmarks
cp -r /your/benchmark/sources  ./tmp_mnt/benchmarks

# Now time to mount /proc, /sys and /dev mount -o bind /proc ./tmp_mnt/proc 
mount -o bind /dev ./tmp_mnt/dev mount -o bind /sys ./tmp_mnt/sys

# Chroot to the image
chroot ./tmp_mnt


Once you've done this, you will be chrooted to your image. Just navigate to 
your benchmark directory (/benchmarks in the case above) and compile as you 
would normally do. Once everything is done, use `exit` to go back to your 
system. Remember to unmount proc, dev and sys from your image once you've 
exited the chroot (`umount ./tmp_mnt/proc` and so on). If compilation went ok, 
then your benchmarks should work.

Re: [gem5-users] Error with GLIBC 2.7 while trying to run C program in FS Mode

2017-02-03 Thread Woo L . L .

Hi Ferran,

I have never done chroot before, so this was my first attempt. What I did was:
a) Install schroot and debootstrap
b) Creating a chroot at my mounted image
c) Edit the schroot.conf
d) Created basic installation of Ubuntu 14.04 in the chroot

But I encountered errors while trying to create a basic installation of Ubuntu 
- all on GLIBC
- Failure trying to run: chroot 
/home/llw1n14RTS/gemfi/x86/disks/mountpoint mount -t proc proc /proc
-   mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found 
(required by mount)
-   mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found 
(required by /lib/i386-linux-gnu/libblkid.so.1)
-   mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found 
(required by /lib/i386-linux-gnu/libselinux.so.1)
-   mount: /lib32/libc.so.6: version 'GLIBC_2.8' not found 
(required by /lib/i386-linux-gnu/libblkid.so.1)
-   mount: /lib32/libc.so.6: version 'GLIBC_2.8' not found 
(required by /lib/i386-linux-gnu/libmount.so.1)
-   mount: /lib32/libc.so.6: version 'GLIBC_2.7' not found 
(required by /lib/i386-linux-gnu/libmount.so.1)

I can't create a basic installation of Ubuntu in my mounted image, and I can 
chroot to my mounted image. All due to the issue of libc.so.6
A check in the folder /lib32, /lib64 and /lib, I found that libc.so.6 is a link 
to libc-2.19.so.
I don't understand what happen. If it is link to libc-2.19.so (which is the 
EGLIBC 2.19 I presume), then logically it shouldn’t have any error on GLIBC. 

Really needed help here.
Thanks.

Elena

Hi Elena,

Maybe you could try to mount the image you are using to run the experiments in 
FS mode, chroot to it and compile these benchmarks there. 
You'll also have to mount /proc, /dev and /sys to your mounte image before 
chrooting.

Hope this helps,

Re: [gem5-users] Error with GLIBC 2.7 while trying to run C program in FS Mode

2017-02-03 Thread Woo L . L .

Hi Pierre-Yves,

I did tried compiling it with the -static flag for the first few benchmarks 
that I have run, but I got a segmentation fault. So, I tried compiling it 
without the -static flag, and it works.

But for this benchmark (QSort and Dijkstra) from MiBench, I tried to compile 
without the -static flag, and I got the error /lib/libc.so.6: version 
'GLIBC_2.7' not found. If I compile it with the -static flag, I got 
segmentation error. 

So I am really stuck at this. Please help.
Thanks.

Elena

Hi Elena,

You should try to compile with the -static flag.

[gem5-users] Error with GLIBC 2.7 while trying to run C program in FS Mode

2017-02-03 Thread Woo L . L .

Hi there,

I run a couple of benchmarks from MiBench Automotive package under FS Mode 
successfully.
I wanted to test other benchmarks from the same MiBench, so I compiled those C 
programs as usual using GCC (I have GCC 4.8.4 in my Ubuntu). No errors in 
compiling and even running it from the terminal.

However, when I try to run it with Gem5 un FS Mode, it gives me the problem 
/lib/libc.so.6: version 'GLIBC_2.7' not found. In my system, I had EGLIBC 2.19 
installed (I checked using ldd -version). I tried to search for some solutions, 
where most users suggest to recompile again with the newer GLIBC (which I did), 
but it didn't solve the problem. I am able to run it from the terminal, but not 
from Gem5.

Has anyone ever encounter this issue and is there a solution to it?
Appreciate all your help.
Thanks.
