| Subject: | [Gems-users] How to count "Privileged" instructions in Opal?? |
|
Hi, I am using GEMS 2.1 to simulate a CMP dual-core system, and I need to count the number of instructions executed in "Privileged Mode" (SuperVisor) and the ones executed in "User Mode". I have found that each instruction has a "m_priv" bit, used to distinguish the mode of execution, and that this bit can be evaluated with the function "getPrivilegeMode()", but I don't know from where to call this function. I need the total number of instructions executed in "Privileged Mode" at the end of the simulation, to be written to the stats file. How could I get this done?? Thank you in advance!! |
