Hi Nikos,

Thanks for your help. 

I tried all possible flags, but I was not able to get the value of those 
variables. If you come across any different approach, then do suggest

Thanks again.

Hi Nikos,

Thanks again. You actually did give an useful hint. 
I used these flags, and I got following type of data:

system.cpu 0x3698a02f73: movDS:[r12 + 0x340], rsi
system.cpu 0x3698a02f73.0  :   MOV_M_R : st   rsi, DS:[r12 + 0x340] :

Thanks a lot for your help. It was really helpful.

Re: [gem5-users] size variable in Packet class

2018-07-10 Thread Google 
Hi Nikos,

Thanks once again. I figured that out.

Can you help me in getting instruction trace for ALU ? I tried doing this for 
X86 system.
What I am trying to do us to get instruction traces for ALU.
What I did:
There is a file, regop.isa (src/arch/x86/isa/microops/). In this file, at line 
506, ADD function is defined. I tried to get the values of psrc1, op2 and 
DestReg, but I don’t think that these are instruction trace. I have attached a 
patch of results below:

2117728 8 2117736
27263459 0 27263459
2117736 8 2117744
29360611 0 29360611
2117744 8 2117752
31457763 0 31457763
2117752 8 2117760
33554915 0 33554915
2117760 8 2117768
35652067 0 35652067
2117768 8 2117776
37749219 0 37749219
2117776 8 2117784
39846371 0 39846371
2117784 8 2117792
2117792 8 2117800
2117800 8 2117808
2117808 8 2117816
2117816 8 2117824
2117824 8 2117832
2117832 8 2117840
2117840 8 2117848

The first column is for psrc1, second for op2 and third is for DestReg. If u 
notice every time the DestReg becomes psrc1 for next operation. And this kind 
of pattern is observed in complete traces. I don’t think this is the 
instruction trace for ALU. And I am not able to find where the ALU instructions 
are defined. I also tried getting traces from mediaop.isa (same folder), but 
sometimes traces are not at all generated. I don’t why.

Any suggestions would a great help to me.

Thanks in advance.

Riddhi

Re: [gem5-users] size variable in Packet class

2018-07-10 Thread Google 
Hi Nikos,

Thanks for your prompt reply. I have one more doubt. Suppose the size of the 
packet is 64 bytes, and the pointer from getConstPtr() will point to 1 
byte data, so for getting all the 64 bytes data, I have to increment this 
pointer, right?

Thanks in advance.

[gem5-users] size variable in Packet class

2018-07-10 Thread Google 
Hi all,

I am asking a very basic question but I am confused as to what the size 
variable in Packet class represents. When I ran dram/sweep.py config file, I 
saw that the size turns out to 1,4,8, and 64 for different cases. In the 
packet.hh, the comment says that size represents the size of request or 
transfer, so is it in bits or bytes ?
There is a data pointer (*data, packet.hh line 333). I want to print out the 
data that this pointer points to for that I need to know the size of the 
request made and accordingly the data will be printed. So I am not able make 
out whether size is in terms of bits or bytes.

Thanks in advance.

Riddhi

this is what I am getting on the telnet terminal. It was continuing for long

If anyone can help it would be great.

[gem5-users] Assertion Failed in getVaddr()

2018-06-01 Thread Google 
Hi,

I am running blackscholes benchmark in X86 system. My command is :
build/X86/gem5.opt configs/example/fs.py –script=runscript.rcS 
--mem-type=DDR4_2400_8x8 --cpu-type=DerivO3CPU -I 1 --caches --l2cache 
--l1d_size=64kB --l1i_size=32kB --l2_size=2MB --l1d_assoc=2 --l1i_assoc=2 
--l2_assoc=8 --cacheline_size=64

This is giving me following error:

gem5.opt: build/X86/mem/request.hh:618: Addr Request::getVaddr() const: 
Assertion `privateFlags.isSet(VALID_VADDR)' failed.

The patch of code in request.hh : 
Addr
getVaddr() const
{
assert(privateFlags.isSet(VALID_VADDR));
return _vaddr;
}

Any suggestions will be helpful.

Thanks,
Riddhi
