[Gems-users] Question regarding CacheMsg class

[Muhammad abid Mughal <mabidm_pieas@xxxxxxxxx>]

hi guys:-

Hope you all doing good.

I just wanna confirm one thing : 

Lets say simics SPARC processor is going to execute Load/Store/Atomic instruction then 

CacheMsg::m_Address;

CacheMsg::m_PhysicalAddress;

represent physical address while   

Address m_LogicalAddress;

represents Virtual address of the data to be fetched by Load/Store/Atomic .

How about this CacheMsg::m_ProgramCounter?

i think this is the address of Load/Store/Atomic in the Instruction cache. Is not it?

If this is the case then for instruction fetches all these data fields 

CacheMsg::m_Address;

CacheMsg::m_PhysicalAddress;

CacheMsg::m_ProgramCounter

are the same?

Waiting eagerly for speedy reply

Thanks

Muhammad abid

  //both have the same value and are physical addresses

  Address m_Address; /**< Line address for this request*/

  Address m_PhysicalAddress; /**< Physical address for this request*/

  Address m_LogicalAddress; /**< Virtual address for this request*/ / this is also same as above see SimicsProcessor.c

  CacheRequestType m_Type; /**< Type of request (LD, ST, etc)*/

  Address m_ProgramCounter; /**< Program counter of the instruction that caused the miss*/ // this is the virtual address

  AccessModeType m_AccessMode; /**< user/supervisor access type*/

  int m_Size; /**< size in bytes of access*/

  PrefetchBit m_Prefetch; /**< Is this a prefetch request*/

  int m_Version; /**< Version associated with this request*/

  uint64 m_Timestamp; /**< The transaction timestamp of this request. Last commit time if request is non-transactional*/
