[gem5-users] Question about L2 misses in ruby.stats

2012-12-07 Thread Jinchun Kim
Hi, All. I was wondering if anyone can make a quick check for L2cache misses in ruby. It seems like the number of L2cache access and miss doesn't show proper numbers. In my simulation, L2cache miss is the exactly same number of L1Dcache miss + L2Icache miss... For example... L1 Dcache Access 110,7

[gem5-users] Pass Kernel Parameters to gem5?

2012-12-07 Thread Joel Hestness
Hey guys, I'm wondering if it's possible to pass parameters to the Linux kernel in full-system mode. If so, can you point me to how to do this? Background: I've narrowed the x86 full-system IDE bug down to some incorrect handling of IDE channels in Linux, and I may have uncovered a fix (here:

2012-12-07 Thread Andreas Hansson
Hi Abhiskek, You do not need to worry about changing any coherent protocol, just place an L3 cache in the right spot. The code you have inlined looks suspicious. I'd say something like: system.l3cache = L3Cache(…) system.membus.master = system.l3cache.cpu_side system.l3cache.mem_side = system.p

[gem5-users] Does splash2 can be run in SE mode now?

2012-12-07 Thread John
