[Qemu-devel] OpenBSD sched_yield() calls increase

2015-06-05 Thread Sai Prajeeth
Hi list, When running OpenBSD on QEMU without KVM, I see an increase in the number of sched_yield() system calls in certain multi-threaded benchmarks (sysbench). However while using KVM accelerator, the number of this system calls is minimal. Does any have any insight why this is happening? The

[Qemu-devel] FreeBSD clock_gettime()

2015-05-31 Thread Sai Prajeeth
Hi list, I have done experiments and it seems that FreeBSD's libc function clock_gettime() results in a system call when running on QEMU whereas on hardware it does not. Does anybody know why? For those interested , you can find the clock_gettime libc call in freebsd source here:
