Hi all, I have problem to get FLexus working under SUSE 8.1, I built my own test application linux on x86 arch by downloading an enterprise disk image(enterprise3-rh73.craff) from simics website. I build gcc 3.4.4 without any errors, I built CMPFlex also without any errors.
Now the next steps that I made. 1) write-config for my test-app 2) export SIMICS_EXTRA_LIB=%flexus%/simulators/CMPFLex, module-list shows flexus module already loaded 3) run simics and read configuration file 4)load-module flexus-CMPFlex-x86-iface-gcc Now I hit with this problem, and I am kind of stuck, I don't know how to solve it. Any help or suggestion would be appreciable.

We had a busy week last week with the ASPLOS deadline. Adding a third (shared) cache is pretty easy. Let's say you want to have private, split L1s (L1i and L1d), then a private, unified L2 followed by a shared L3. Have a look at simulators/CMPFlex/wiring.cpp That's where all your changes are going to go. Look in that file at how L1d and L2 are created, initialized, and wired. You will need to add an L3 that is a copy of the L2 there now, and the L2 is going to look more like L1d does currently. You will have to add an I/D mux between the split L1s and L2 (IDCacheMux). You can see how this mux is created/wired by looking at simulators/UniFlex/wiring.cpp Here's a 'checklist' for a single component. Make sure each of these is set properly for your L2, L3, and IDCacheMux. 1) The #include at the beginning to reference the component (IDCacheMux) 2) CREATE_CONFIGURATION macros 3) initializeParameters() 4) FLEXUS_INSTANTIATE_COMPONENT -- note: your IDCacheMux should be in a FLEXUS_INSTANTIATE_COMPONENT_ARRAY macro (unlike in UniFlex), because there is one mux *per core* 5) wiring -- WIRE() macros 6) DRIVE() macros -- your IDCacheMux won't need one. L1s, L2, and L3 will. If all you want is another shared L3 below the shared L2, the job is even easier. I trust the above will explain this scenario as well. Let us know if you run into any trouble.
