Re: [Gems-users] rubu0.init step fails: how can I debug this:

[Dan Gibson <degibson@xxxxxxxx>]

x86 targets don't allow stalling of instruction fetch... can you try again without the "instruction-fetch-mode instruction-fetch-trace" and "istc-disable" steps?

Regards,

Hi:

I am using GEMS (Release 1.1 for GEMS and SIMICS 2.2)  for x86 target/host machine in Linux  - I used the patch for x86.

I am following the quick steps as given in: http://www.cs.wisc.edu/gems/doc/wiki/moin.cgi/QuickStart

I used the checkpoint file which is taken from (I am not sure this has something to do with the failure that I am seeing):
$GEMS/simics-2.2.19/home/firststeps/fs-config-1

I did the following commands and found the job to be killed after I applied ruby0.init command. The details are given below.

Please let me know how I can debug this or if I am not doing it right somewhere:
--------------------------------------------------------------------------------------------------------------------

[patwarya@chipdesign MOSI_SMP_bcast]$ ./simics -stall

simics> read-configuration /home/patwarya/GEMS/simics-2.2.19/home/firststeps/fs-config-5

Then I got a pop-up window with title as:
Simics Console: con0

The Debian GNU/Linux is booted.

Then I applied following commands:

simics> instruction-fetch-mode instruction-fetch-trace

simics> istc-disable

simics> dstc-disable

simics> load-module ruby

simics> ruby0.setparam g_NUM_PROCESSORS 1

simics> ruby0.setparam g_MEMORY_SIZE_BYTES 4294967296

simics> ruby0.init
