Re: [gem5-dev] Multicore ARM v8 KVM based simulation

2018-04-04 Thread Andreas Sandberg
That's very strange. It seems like the KVM GIC interface is trying to read register 0x9 in the GIC's CPU interface. The errno indicates that no such register exists, which is expected (registers are usually 32 bit aligned). I'm not why this happens. The write is /probably/ coming from the simul

The performance impact shouldn't be too bad. I did some scalability tests using LU from SPLASH 2 years ago. IIRC, I was using an 8-core Westmere-EX based system at the time. Native throughput for that benchmark was ~30GIPS @ 8 cores. When running in KVM, I got something like ~15GIPS with a 1ms

[gem5-dev] virtual timer in ARM KVM
