Re: [Gems-users] Questions about load ruby in Simics and Power in opal

["Cihat Basol" <cihatbas@xxxxxxxxxxxxxxx>]

Hi Yang,

I faced the exact same error. The thing is that in simics 3.0, SIM_hap_register_callback is obsolete. You can just go into ruby.c file and comment out the lines that includes that function. There are in fact 4 or 5 of those functions mostly about mmu. But I am not sure if it is the right thing to do. However, I haven't encountered any problem due to disabling those callback so far. 

Thanks,
Cihat.

Hi there,

I have two questions now, would anyone know these issues?

 

1. In fact I have posted this question two weeks ago, but didn't get any information, and I would like to post it a second time in case that some of you guys were on holidy at that time. 

 

I'm now using GEMS2.0. And I configured the simulation system using MOESI_CMP_directory protocol. And the system was configured as 4-processor 4-l2 banks and 4 memories. Now, I can run tester in ruby. But when I tried to load ruby into simics, the following error occured.

 

Error loading module 'ruby': Failed to load module 'ruby' ('/scratch/cerberus/guoyang/simulators/Gems/2.0GEMS/simics_3_workspace/x86-linux/lib/ruby.so'): "undefined symbol: SIM_hap_register_callback"

  

And I checked Gems1.4, there is no function call of SIM_hap_register_callback. Is there anyone know how to solve this problem or explain why would this happen?

 

2. I also noticed that there is a "power" directory in opal and I also found the wattch power in opal. My question is: is the power thing in opal the same as in Wattch, and does this piece of code work properly or tested properly?

 

Many thanks,

 

Guoqiang Yang
