Hello,

Could you please clarify whether Konata supports displaying of retire and store completion stages like gem5 trace viewer?

At quick glance on Konata gem5 parser I see that the code is aware about "retire" and "mem_complete" stages . But I don't see these stages - no "mem_complete" for store operations and no "retire" for all operations (please see attached screenshot).

gem5 version is v22.1
Konata version is v0.39

Hi,
I have downloaded the Linux zip file. Readme says run the file named Konata, but I dont have an application that can run it. Since I am a newbie,I do not know the command to execute it in terminal.
Please tell me what command to use to run the file and install konata
Regards,
Thanks

Hello,
Noticed that when S and E or R commands are in one cycle then it will not be visible in Konata.

E.g.

I    0    0    0
...
C    1
S    0    0    Rt
R    0    0    0
C    1

Here, Rt stage will not be displayed.
It can be OK with Retire stage, but i ran into problems with flushed instructions

In my case, it is possible to Fetch an instruction and flush it in the same cycle

...
C    1
I    0    0    0
S    0    0    F
R    0    0    1
C    1
...

So instruction will not be visible at all, only if you hover the cursor over it on the left, you can see that it actually existed and was flushed.

What i wanted to see here is:

I'm dumping stages to kanata trace "on fly" when simulator works, and I only know the moment at which the instruction enters the stage, but not when it leaves it. This forces to create some buffers for R and E stages to be printed on the next cycle, which doesn't seem to be a good option for me.

So the question is, is there a particular reason for not displaying these instructions?
And is it possible to display them? Maybe with some new option.

Konata version is v0.39

Hello. Could you help me? I'm newbie and don't know how to theme change. I've tried to change config.js (this.theme = "light"; ), but it does not work

Hello,
I noticed that when choosing to colour instructions based on ThreadID, all instructions have the same colour regardless of the thread. Moreover, when hovering to any instruction in the left pane, the TID field is always 0.

For example the following inst (sn: 5250) belongs to thread 1 as we can see from the O3CPUAll log:

5504500: global: DynInst: [sn:5250] Instruction created. Instcount for system.cpu = 33
5504500: system.cpu.fetch: [tid:1] Instruction PC (0x101ce=>0x101d0).(0=>1) created [sn:5250].
5504500: system.cpu.fetch: [tid:1] Instruction is: c_addi a5, 8

But in Konata is it displayed as if it was belonging to thread 0:

Let me know if I'm missing anything. Thanks!

HElP!
How to make pipeline stage in the red box invisible？ I mean all these 1234 stages.
I tried to add extra RETIRE Instructions but was there any other way?'
thank you.

Hello, I found a problem that Konata will ignore the chart about an "only a fetch stage" instruction.
Is this a bug?

O3PipeView:fetch:199000:0x00010100:0:45:c_bnez a5, 12
O3PipeView:decode:0
O3PipeView:rename:0
O3PipeView:dispatch:0
O3PipeView:issue:0
O3PipeView:complete:0
O3PipeView:retire:0:store:0

Do i use it on the web page? Is there a web version?

Could you help me - it seems like W command does not work, i don't see any arrows. What am I doing wrong?

I have downloaded the most recent binary (v0.34, konata-darwin-x64.tar.gz) under MacOS Mojave and copied konata.app into /Applications.

When I launch it, it takes a minute or so to crash, and the crash report is attached below. (I also had this issue with a previous version on MacOS High Sierra)

A presentation of the tool in ASPLOS 2018 is provided in the repo description, but apparently the link (http://learning.gem5.org/tutorial/presentations/vis-o3-gem5.pdf) is unreachable.
Is it possible to upload the presentation somewhere else?

Hello,

I am using the latest gem5 release (v22.1) and the latest pre-built Konata (v0.38).
I see that "View->Dependency arrow" menu option is available but it doesn't change displaying in any way.
The trace was collected with "--debug-flags=O3PipeView,O3CPUAll".

Could you please clarify what is the proper way to enable dependency arrow for gem5 trace (maybe some additional options, patches should be applied)?

Hi,

Like in a disassembler, we work with hundreds, thousands, even millions lines of code in a simple window. And like in main disassembler, it will be super helpful to have the possibility to annotate the code, with some kinds comments, for example in the left-panel.

This is just a suggestion. Hope it's appreciate!

P.S. : Thanks for the great work, Konata is very useful!

Hello,

This is really awesome tool, but I found a bit incovenient when I try to check how many cycles b/w one instrctuction and some distant instructions else, e.g. in below figure, the first and next retired.

Consider to add some vertical cursor(s) when clicking on a pipe stage? even 2 or more and a diff can automatically show on statusbar, somewhat like waveform tools such as synopsys VERDI. :-)
