Hi, Thanks a lot for your reply.
I got the CPU info by printing the /proc/cpuinfo file on the image while on full system mode on gem5. Can we safely assume that the following flags are fully implemented and functional? For example, as per this page from gem5 documentation <https://www.gem5.org/documentation/general_docs/architecture_support/>, only SSE is implemented and x87 is partially implemented, however, the following flags say something a bit different that SSE2 is supported. So, again, my question is: Can I safely rely on these flags being fully implemented? flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat > pse36 clflush acpi mmx fxsr sse sse2 ss tm ia64 pbe syscall nx mmxext > fxsr_opt rdtscp lm 3dnowext 3dnow nopl cpuid pni monitor ssse3 lahf_lm cpb > proc_feedback pti clflushopt clwb overflow_recov Thanks. -- *Best,Abdelrahman Hussein* MSc.
