Hi Bjoern, There are a number of people who use x86 with gem5. Personally, I use x86 almost exclusively. As I'm sure you know, the initial full-system support was geared towards Linux. My experience is that x86+Linux works pretty well (functionally at least). We have run into a number of x86 bugs over the years, but from my point of view, it's pretty stable. However, I'll admit I'm mostly interested in the memory system, not the core microarchitecture. I haven't spent much time doing performance debugging of the core. I'm happy if it can issue one memory request per cycle.
Additionally, I believe the folks at AMD who use gem5 are primarily using the x86 ISA. However, I shouldn't speak for them :). What kinds of problems are you running into? Mostly issues with the system support (interrupts, APIC, etc)? Or are you actually finding issues with the instruction implementations? Jason Jason On Mon, Apr 11, 2016 at 7:50 AM, Bjoern A.
