[gem5-users] run a binary file for 3 times on gem5

[ABD ALRHMAN ABO ALKHEEL via gem5-users]

Hi All,

How to run a binary file three times on gem5? I want to find the execution time 
for a binary file for 1M instructions. However, the gem5 is completed on 400K 
instructions because the binary file is completed. So how I can run it three 
times in order to reach 1M instructions?

For example, If I want to run the hello world on gem5 using the following 
command, the gem5 will end before reach 10k insts since hello needs only 5k 
insts to finish. So ho i can run it for 3 times?

build/X86/gem5.opt configs/example/se.py -I 1 -c 
tests/test-progs/hello/bin/x86/linux/hello --cpu-type=DerivO3CPU --caches

Any help would be appreciated.

Hi Ayaz,

Thanks for your help.

Can I do it through the page cache by getting the page (page descriptor 
structure) corresponding to the file in vfs_write call? If so do you know where 
should I make the changes?

Thanks

Hi,

Based on my understanding of what you are trying to do, I would suggest looking 
into src/arch/x86/tlb.cc (assuming you want to use x86) around line 400, to see 
how to access page table entries from a process pointer. syscall_emul.hh 
already includes sim/process.hh, so you can follow what is done in tlb.cc and 
play with the flags that you want to change.

Subject: [gem5-users] Cannot read from main memory with a new cpu port similar 
to dcacheport

Hi everyone,

I have created a new cpu port which accesses the main memory and bypassing the 
caches when reading from memory. When I try to read from the main memory via 
this port, I sometimes fail to read it and it is read as a 0. This only happens 
when I try to read a value almost after updating it. i.e. it does not update 
that value in the main memory.

What I think is that the value is still stored in the cache, and the cache has 
not yet updated that value in the memory.
How can I make sure that the cache has also written it to the main memory? i.e. 
enforce writethrough.

If my observation is wrong, would someone correct me as to why this is 
happening and what I might be doing wrong?


Thanks,
Aamir

Hello,

This depends on your memory system. If your cache can accept more than one 
request per cycle, then the CPU can send more than one request. The 
`sendTimingReq` returns false when the receiver cannot receive another request.

It's hard to know exactly what your memory system looks like, but if you're 
using non-coherent crossbars between different levels of caches, you're 
probably going to be seeing some errors in your memory. The non-coherent 
crossbar was designed to be put below (closer to memory) a "point-of-coherence" 
crossbar. Also, I believe that by default that crossbar is on 16 bytes wide, so 
a single cache line request could take 4 cycles, which might be why the CPU is 
blocking?

Cheers,
Jason

Hi everyone,

Is it possible to send more than one memory request from the dcacheport to the

when one memory instruction is send to the memory, then another memory request 
cannot be send to the memory as sendTimingReq  returns boolean type false. And 
it has to wait until the previous memory response is back then  issue the next 
one .

My goal is to allow the MinorCPU to have overlapping memory requests to the 
memory, therefore is it possible to achieve this by sending more than one 
memory request to the memory? as I cannot figure this out.
I am currently using noncoherent Xbars to connect my caches and the memory 
system, would I need to change it or is there something else that i have to do?

Any help would be appreciated.

Have a look at the source under Eclipse :-) all of those get the
packet data with small variations, but it is raw binary.

To see it as hex you need to convert binary to ASCII hex first. I want
to push a simple patch for this in the near future, but you can do it
manually easily too for now:

Hi Ciro,

Could you tell me where can i find the file that does an ifetch for 
AtomicsimpleCPU in gem5?

Also, How to print the data from the packet (I assumed the loaded data is 
stored in the pkt).
should I use
pkt->getRaw()
or
pkt->getLE()
or
pkt->getBE()
or
pkt->setData()
or
pkt->writeData()

Thanks

Subject: Re: [gem5-users] Re: Memory Addresses in Gem5

I recommend that you have a look at the source of how AtomicSimpleCPU
does an ifetch under Eclipse. It should be easy to understand
everything quickly from there.

The Packet address is physical (which notably what caches and DRAM
work on), just have a look at the constructor of packet:

Packet(const RequestPtr &_req, MemCmd _cmd)
:  cmd(_cmd), id((PacketId)_req.get()), req(_req),
   data(nullptr), addr(0), _isSecure(false), size(0),
   _qosValue(0), headerDelay(0), snoopDelay(0),
   payloadDelay(0), senderState(NULL)
{
if (req->hasPaddr()) {
addr = req->getPaddr();

So you have to do translation before. Translation sets the physical
address on the Request, which contains both _paddr and _vaddr fields.

Another option is to have a look at how some of the memory tests are doing it.

I recommend that you have a look at the source of how AtomicSimpleCPU
does an ifetch under Eclipse. It should be easy to understand
everything quickly from there.

The Packet address is physical (which notably what caches and DRAM
work on), just have a look at the constructor of packet:

Packet(const RequestPtr &_req, MemCmd _cmd)
:  cmd(_cmd), id((PacketId)_req.get()), req(_req),
   data(nullptr), addr(0), _isSecure(false), size(0),
   _qosValue(0), headerDelay(0), snoopDelay(0),
   payloadDelay(0), senderState(NULL)
{
if (req->hasPaddr()) {
addr = req->getPaddr();

So you have to do translation before. Translation sets the physical
address on the Request, which contains both _paddr and _vaddr fields.

Another option is to have a look at how some of the memory tests are doing it.

[ABD ALRHMAN ABO ALKHEEL via gem5-users]

Hi,

Thank you for your email.

Do you have any idea how to construct a packet with a request to read from the 
memory address? For instance, let us assume that the address that I want to 
read the data from it is (0x2345),  I want to read the 256 bytes of this 
address (0x2300-0x23ff)? I want to do that for debugging like this 
https://www.gem5.org/_pages/static/scripts/part2/memoryobject/simple_memobj.cc.

Any help would be appreciated.

Thanks

Hello Jason,

It is for a debug-only read and I want to see what is in the main memory only 
not in the cache.

Thanks for your email, I really appreciate that.

Hello,

Is this a debug-only read or are you trying to simulate the timing for the 
read? Do you want to see what's in the main memory or do you want to see the 
up-to-date values in the caches? The answers to these questions will drive what 
type of access you want to make and what object you want to use to make the 
access.

Generally, you can simply construct a packet and send a request of any size to 
any object. See 
http://www.gem5.org/documentation/learning_gem5/part2/simplecache/ for details 
on how to send/receive memory requests.

Cheers,
Jason

Hello,

First of all, please reply to the users list, not directly to the person who 
responded. This allows everyone to see answers and/or chime in and help.

Second, the page you linked is out of date. Please use the main gem5 website 
for all of the up to date documentation (e.g., 
http://doxygen.gem5.org/release/current/classLSQUnit.html)

Third, I still don't fully understand what your goals are. However, you can use 
the system port (actually, I think I was wrong before, you should use the 
"getPort" function, not "getSystemPort") to make functional (or debug) accesses 
to the memory. You can create a `Packet` with a `Request` and send a functional 
request across the port (i.e., call sendFunctional(pkt)). You can use either 
virtual (in SE mode) or physical address (in both modes). I am sure there are 
some caveats to using virtual addresses, but I don't know exactly what they are.

If you're trying to make new timing accesses, then you should use the main 
"dcache_port" and "icache_port" that are connected to the CPU. Again, you can 
construct a Packet object with a Request and send it across the port (e.g., 
sendTimingReq(pkt)).

You may want to read up on the details of how gem5's memory objects work:

Hi Jason,

What I want to do is finding the memory address that the LD instruction loads

the lsqunit)http://pages.cs.wisc.edu/~swilson/gem5-docs/classLSQUnit.html and 
saving those addresses. After a specific time, I want to access the memory to 
read the data from those addresses. Can I use getSystemPort function to access

virtual address or the physical address?

Hi Alrhman,

Look into the protocol state machine, say L1cache state machine. More 
specifically you can modify the mandatory_queue_in code for your requirement. 
The sequencer puts the CPU request into mandatory queue.

Revert incase of any query.

hello Abd,

You can see a similar output by enabling the Exec debug-flag. I would suggest 
you look at the gem5 documentation to further details in the debug-flags 
available and how to use them. 
(http://learning.gem5.org/book/part2/debugging.html#:~:text=gem5%20provides%20support%20for%20printf,enable%20from%20the%20command%20line.)

A quick answer for you question is the following command :

./build/x86/gem.opt  --debug-flag=Exec configs/se.py -c 

With this command, the output will be printed in the console. You can also 
redirect the output to a file by adding --debug-file=file.txt.

Tip: You can use grep to filter only memory access.

Best regards.

I'm afraid I don't have a super automated setup that just works for
Android, and haven't done this myself specifically, but here are some
thoughts:

- those instructions are like large part of the wiki old and may have
stopped working --machine-type=VExpress_EMM is not recommended anymore,
the default and recommended and often tested platform is VExpress_GEM5_V1
- try one of the newer kernels
- is it really representative to run experiments on 32-bit arm now that

Re: [gem5-users] Fw: Asim benchmarks on gem5

[ABD ALRHMAN ABO ALKHEEL]

Thanks Ciro for your email. I can build new image and new kernel but the 
problem is how to get the benchmarks from the old image? Is there anyway to get 
the image working on qemu to take copy of the benchmarks ? Best Regards

I'm afraid I don't have a super automated setup that just works for
Android, and haven't done this myself specifically, but here are some
thoughts:

- those instructions are like large part of the wiki old and may have
stopped working --machine-type=VExpress_EMM is not recommended anymore,
the default and recommended and often tested platform is VExpress_GEM5_V1
- try one of the newer kernels
- is it really representative to run experiments on 32-bit arm now that
all Android phones are 64-bit?

I don't know what is going on. As I have already explained in previous message, 
it is better to run the commands interactively the first time instead of using 
a script. So that it possible to understand where you are failing.
My questions are anyway:

1) Why aren't you logging in as root? (just type root in the username)
2) If you really need to access with a non root user, you should sudo EVERY m5 
call. Are you still executing the script as it is?
I can see how by failing to execute m5 pseudo instructions you are neither 
dumping stats nor exiting simulation
(m5 exit won't be recognized and Linux will keep going waiting for another 
command from the terminal).

Kind Regards

Giacomo

That's strange, I've never run into this problem, but my setup is quite

at the first m5 command.  Didn't it return when it reached that point?

Output seems fine, but if I understand correctly, it never finishes

this --maxinsts so I don't really know if and how it works.  Have you
been able to run gcc with test input? Does it finish properly?

I don't know what is going on. As I have already explained in previous message, 
it is better to run the commands interactively the first time instead of using 
a script. So that it possible to understand where you are failing.
My questions are anyway:

1) Why aren't you logging in as root? (just type root in the username)
2) If you really need to access with a non root user, you should sudo EVERY m5 
call. Are you still executing the script as it is?
I can see how by failing to execute m5 pseudo instructions you are neither 
dumping stats nor exiting simulation
(m5 exit won't be recognized and Linux will keep going waiting for another 
command from the terminal).

at the first m5 command.  Didn't it return when it reached that point?

Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode

[ABD ALRHMAN ABO ALKHEEL]

Hi Giacomo,

I have run the command and the gcc.rcS script below but the script doesn't stop 
at 1000 instructions. Any help would be appreciated.

The command is:
./build/X86/gem5.fast ./configs/example/fs.py --maxinsts=1000 
--kernel=/home/abdkhail/linux_new/vmlinux 
--disk-image=/home/abdkhail/ubuntu16.img 
--script=configs/boot/benchmark/gcc.rcS --mem-size=3GB --num-cpus=4 
--cpu-clock=2GHz --caches --l2_size=2MB --l1i_size=32kB --l1d_size=32kB 
--checkpoint-restore=3

The gcc.rcS is:

cd 
/home/ubuntu/cpu/benchspec/CPU2006/403.gcc/run/run_base_ref_amd64-m64-gcc42-nn.
/sbin/m5 resetstats
./gcc_base.amd64-m64-gcc42-nn 166.i -o 166.s
/sbin/m5 dumpstats
#echo "Done :D"
/sbin/m5 exit

This also what i got on the output screen:

Global frequency set at 1 ticks per second

assigned (4096 Mbytes)

If by chance simulation is stuck while generating a checkpoint, I suggest you 
to use GDB to understand where it is stuck.
Let us know your findings.

I don't know what is going on and what the boot script is doing.
For me the easy way to create a checkpoint is to

1) $cd util/term
2) $make

Now you have m5term compiled.
>From another terminal run your simulation (without bootscritpt) and see which

Now you have a terminal attached to your guest system: once you boot Linux, 
just type on this terminal:

$/sbin/m5 checkpoint

This will create a checkpoint.
If you now want to exit simulation, type on the same terminal

$/sbin/m5 exit

I guess using -l 10 is not enough to reach the benchmark itself and you 
finish before bootup, that's why you observe the same behavior.  To create the 
checkpoint after boot, you need to run the script found in

configs/boot/hack_back_ckpt.rcS.  Run it like this:

gem5.opt \

--outdir=a/directory/to/store/boot_ckpt \
configs/example/fs.py \
--kernel=...\
--disk-image=... \
--script=/configs/boot/hack_back_ckpt.rcS \
--cpu-type=AtomicSimpleCPU --num-cpus=1 --mem-size=...


You should have your checkpoint in the director you set with outdir.


To run from the checkpoint you need to use the following with your fs.py:

--checkpoint-dir=a/directory/to/store/boot_ckpt -r 1

No, it should take a couple of hours tops (for me it was like half an hour I 
think).  Try using gdb as Giacomo suggested and also maybe share the command 
you used to run gem5.  You can also run gem5 and attach a terminal (look at the 
wiki of how to do this).  This will give you interactive access to gem5, while 
running, and maybe you can see this way where it gets stuck, if that's the case.

Can you share the output from stdout and stderr?  Also have you checked 
system.terminal? There may be some clues of the error there as well if the 
commands in the rcs script are not correct or you have any missing dependencies 
in your disk image, for whatever reason.

You can also try to first generate simpoints etc for a simple program, 
something like a simple loop in C, so that we can figure out if the problem is 
in the SPEC or gem5.

Hi Dimitrios, thanks for your help. I really appreciate that. Could you please 
tell me how much time does it take to run hack_back.rcS?

I guess using -l 10 is not enough to reach the benchmark itself and you 
finish before bootup, that's why you observe the same behavior.  To create the 
checkpoint after boot, you need to run the script found in

configs/boot/hack_back_ckpt.rcS.  Run it like this:

gem5.opt \

--outdir=a/directory/to/store/boot_ckpt \
configs/example/fs.py \
--kernel=...\
--disk-image=... \
--script=/configs/boot/hack_back_ckpt.rcS \
--cpu-type=AtomicSimpleCPU --num-cpus=1 --mem-size=...


You should have your checkpoint in the director you set with outdir.


To run from the checkpoint you need to use the following with your fs.py:

--checkpoint-dir=a/directory/to/store/boot_ckpt -r 1

Can you share the output from stdout and stderr?  Also have you checked 
system.terminal? There may be some clues of the error there as well if the 
commands in the rcs script are not correct or you have any missing dependencies 
in your disk image, for whatever reason.

You can also try to first generate simpoints etc for a simple program, 
something like a simple loop in C, so that we can figure out if the problem is 
in the SPEC or gem5.

Hi,

Here is an example of an .rcs script.  As Ciro told you, first you need to have 
a bootable image, optionally create a checkpoint after boot and finally add the 
benchmarks to the cd image.

#/bin/bash
cd 
/your/path/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/run/run_base_refspeed_aarch64-64.
/sbin/m5 dumpresetstats

/sbin/m5 exit

In the example above you simply cd to the directory of the benchmark you want 
to use and then run it.  /sbin/m5 dumperesetstats resets your statistics 
counters and exit is used to finish the executi

a bootable image, optionally create a checkpoint after boot and finally add the 
benchmarks to the cd image.

#/bin/bash
cd 
/your/path/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/run/run_base_refspeed_aarch64-64.
/sbin/m5 dumpresetstats
/yourpath/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/exe/cam4_s_base.aarch64-64
/sbin/m5 exit

In the example above you simply cd to the directory of the benchmark you want 
to use and then run it.  /sbin/m5 dumperesetstats resets your statistics 
counters and exit is used to finish the execution.  Note I use spec 2017, which 
I found that it's best to run directly as I do above than use their 
infrastructure.  Problem is that FS is too slow and you waste a lot of time 
running their python scripts.  Also, I would encourage you to learn about 
simpoints<

I am not sure if this is possible in FS, at least not the same way you do in 
SE.  You will need to use simpoints in order to create checkpoints for you 
code.  After that you basically segment your code into smaller, say 100 
instructions per segment, which you can run.  Check the link I sent in my 
previous message.  However note that you will need to run the code for each 
benchmark  twice, once for generating the simpoint files and once to set the 
checkpoints.  For me this can take up to 4 week for the larger codes, and a few 
days for the smaller ones in SPEC CPU 2017.  Once you have the checkpoints 
though, it should take a couple of hours.  I don't know if there is a faster 
way to do this, maybe someone else has a better suggestion.

Hallo,
which g++ version do you use for building gem5?
Try removing build directory or scons -c and build with g++-7 to see if that 
fixes antything.

Hi Matt,

Thanks for your suggestions. Refer to this thread

Hi Andrew,

Normally this error indicates that something with your ROCm setup is wrong -- 
you can look through the mailing list archive and see a few examples of people 
with the same types of errors along with the suggestions (e.g., what kind of 
traces) to get to start debugging the problem.  Why did you install ROCm 1.6.1? 
 If you look at the wiki, AMD suggests using 1.6.x instead: 
http://gem5.org/GPU_Models#ROCm_tool_chain_and_software_stack.  I can't promise 
that changing from 1.6.1 to 1.6.x will solve your problem, but it would be a 
good start/thing to check.  Also, I'm not familiar with this sample program -- 
does it assume the device is a discrete GPU?  If so, the gem5 AMD GPU model 
assumes the GPU is tightly coupled and cache coherent.  So you would need to 
remove those copies (although it appears your failure is happening sooner than 
that).

Thanks,
Matt

[ABD ALRHMAN ABO ALKHEEL]

Thanks Gerzhoy for your email.

The code is attached here. I got the error for some of benchmarks not for all.

I used this command to run the code
/home/abdkhail/aa/gem5/build/X86/gem5.opt --outdir=/home/abdkhail/aa/gem5/o1 
/home/abdkhail/aa/gem5/configs/example/spec06_config.py -I 10

--benchmark_stderr=/home/abdkhail/aa/gem5/o1/povray.err --cpu-type=DerivO3CPU 
--caches

I observed when i changed --cpu-type=DerivO3CPU  to another CPU type it is 
working fine but i have to get the stats output of this type 
--cpu-type=DerivO3CPU .

It looks like gem5 itself had a segfault.

Did you change the simulator code itself?
If so I would look at whatever code you added to see if you referenced a memory 
address you don't actually have access to.

You could run the simulator in GDB as well and add breakpoints to debug further.

Re: [gem5-users] AMD GPU compute model run fail

[ABD ALRHMAN ABO ALKHEEL]

I got this error ( gem5 has segmentation faults) please help me.

Subject: Re: [gem5-users] AMD GPU compute model run fail

Hi Andrew,

Normally this error indicates that something with your ROCm setup is wrong -- 
you can look through the mailing list archive and see a few examples of people 
with the same types of errors along with the suggestions (e.g., what kind of 
traces) to get to start debugging the problem.  Why did you install ROCm 1.6.1? 
 If you look at the wiki, AMD suggests using 1.6.x instead: 
http://gem5.org/GPU_Models#ROCm_tool_chain_and_software_stack.  I can't promise 
that changing from 1.6.1 to 1.6.x will solve your problem, but it would be a 
good start/thing to check.  Also, I'm not familiar with this sample program -- 
does it assume the device is a discrete GPU?  If so, the gem5 AMD GPU model 
assumes the GPU is tightly coupled and cache coherent.  So you would need to 
remove those copies (although it appears your failure is happening sooner than 
that).

Thanks,
Matt

[gem5-users] Fw: stats seem to be wrong in multicore simulation using SE mode

[ABD ALRHMAN ABO ALKHEEL]

Hello,

I wanna run sha3 algorithm (hashing function) on gem5 for million instructions. 
The algorithm runs as follow:
sha3sum 256 file path.

I added these parsers on se.py
parser.add_option("-a", type="int")
parser.add_option("-b", type="string")

I run this command
build/X86/gem5.opt configs/example/se.py -I 100 -c 
/home/abdkhail/project2/gem5/SHA3IUF/sha3sum -a 256 -b myfile  
--cpu-type=DerivO3CPU --caches

The algorithm runs only 100 thousand instructions and then exits even if I 
passed the large file to the algorithm.

Exiting @ tick 188440500 because exiting with last active thread context
Simulated exit code not 0! Exit code is 1

Any help, please.

Best Regards

Maybe num_idle_cycles? But not sure, I would try to check if the
