[Gems-users] Segmentation Fault

[Sasa Vitorovic <savitor@xxxxxxxxx>]

Hi,

I bolded some code in quotation below. As far as I know, to set up 4 processors with shared 512mb you need to write:

@boards = {0 : [[0, 4, 512]]}

and not

@boards = {0 : [[0, 4, 2048]]}

This is case for Simics 2.x, in Simics 3.x there is $megs_per_cpu variable. In Simics 2.x, this is shared memory for all processors on board.

I know this issue is out of date, but I hope this can help to clarify things.

Hi, 
We are having a similar problem as the one that had
Arrvindh this march. Sudenly when we try to load Ruby
we get a segmentation fault like that:

...

The original configuration with the simics script is
the following:

# set up 4 processors with 512MB
@boards = {0 : [[0, 4, 2048]]}
@sarek_disk_size = 4256972800L
@sarek_files = [["sarek-sol9-install.disk", "ro", 0,
4256972800L]]

Also if we check the memory in simics it appears like
that:

simics> phys_mem0.map
base               object     fn offs   length        
  
0x0000000000000000 memory0    0 0x0     0x80000000
0x000007fff07ffff0 hfs0       0 0x0     0x10      
simics>

Does anyone know how to solve this problem?
Thank you very much
