Re: [Gems-users] CacheMemory functions

[Dan Gibson <degibson@xxxxxxxx>]

Liz,
1. Tracking down the control flow for allocate(), etc., will be a little tricky, since it will snake through a lot of SLICC-generated C++ code in your $RUBY/generated directory. I recommend you either attach a debugger (e.g., when using the Ruby tester) and step through function calls, or just "grep -Rl pattern *" to find the files with matching call sights.
2. Look in $RUBY/system/MachineID.h. 
3. There are 50+ actions in MSI_MOSI_CMP_directory-L2cache. What do they do? They describe the actions of the L2 controller. If you want to ask about one in particular, perhaps we can answer.
4. To find cacheProbe, use grep as before.
5. There is a $RUBY/system/PerfectCacheMemory.h you might find useful. If not, use grep.
6. Typical instantiations of <class ENTRY> in Ruby are anything with "Entry" in the class name in your $RUBY/generated/[protocol] directory. E.g, L2Cache_Entry.h

Regards,
Dan

Hiii,

I would like to know from where the allocate() , cacheAvail() and cacheProbe() in CacheMemory.h are being called in case of L2cache..........I would like to get the id of the core that is issuing the address to these functions...From where i will get that in CacheMemory.h...wat statement I need to add when these functions are being called and where... As u said,
https://lists.cs.wisc.edu/archive/gems-users/2010-January/msg00029.shtml
I used L2cacheMemory.monitorId(in_msg.RequestorMachId) whereever i saw peek(L1RequestIntraChipL2Network_in,Requestmsg) in ACTIONS of MSI_MOSI_CMP_directory-L2cache.sm file.......bt I need it while the above functions are called...I didnt find calling of these functions in ACTIONS  except L2cacheMemory.allocate(address).....But there also, I am not allowed to use the above said statement......I just tried L2cacheMemory.monitorId(MachineID) ....but Is that machineID the core id????. wat I should I do for that.....??

What the actions in MSI_MOSI_CMP_directory-L2cache.sm file do??

Where the control goes from the cacheProbe????

What the PerfectCacheMemory file  do??

What are the different instantiations of template <class ENTRY>....the value used for ENTRY parameter for instantiation of L2 cache??
Thanks in advance
Liz
