[Gems-users] Ruby Segmentation fault (SIGSEGV) in main thread

[Shirshendu Das <shirshendu.iitg@xxxxxxxxx>]

Hi,

  I am using GEMS. I have modified L2 controller of  MESI-CMP  protocol  (MESI_CMP_directory-L2cache.sm) and also the "ruby/System/CacheMemory.h" to meet my requirements. It compiles correctly but after loading and initiating ruby it shows segmentation fault.  I attached the error below:

simics> ruby0.init

......

simics> ruby0.tracer-output-file /home/....../tracer/water/watertrace.caches.gz

Request trace enabled to output file '/home/..../tracer/water/watertrace.caches.gz'

simics> c

Segmentation fault (SIGSEGV) in main thread

The simulation state has been corrupted. Simulation cannot continue.

Please restart Simics.

[cpu0] v:0x0000000001055484 p:0x01802c55484  ldsh [%o1 + 34], %o3

Setting new inspection cpu: cpu0

I don't know where the problem is. Kindly help me how can I fix this problem.
