Hello, I need to find out the virtual address of the instruction which is being executed (i.e. program counter) when a (data) memory access to a particular virtual page (ex. 0x000aa) takes place. The instruction address does not have to be very precise. Using the instruction address I am going to find out which part of the code is being executed at that moment. I am using ARM with O3 model in FS mode.
I am thinking of stopping gem5 using a conditional breakpoint on the virtual page number in GDB and then, look up the PC. I know where to put the breakpoint (TLB::translateFs?). But I have trouble finding the PC in O3 CPU. Thank, Farzad??
