upgraded to latest bsdrp
look at my sysctl dev.cpu output (it's on every cpu)
dev.cpu.1.cx_usage: 100.00% 0.00% last 49455us
dev.cpu.1.cx_lowest: C1
dev.cpu.1.cx_supported: C1/1/1 C2/2/41
i run pmcstat and see this
41.4 kernel acpi_cpu_idle_mwait acpi_cpu_idle
ok. I have added in /etc/rc.conf -> performance_cx_lowest="LOW"
rebooted the system
now this is how the sysctl dev.cpu looks like
dev.cpu.0.cx_usage: 2.25% 97.74% last 4711us
dev.cpu.0.cx_lowest: C8
dev.cpu.0.cx_supported: C1/1/1 C2/2/41
in pmcstat there is a new string with high %
%SAMP IMAGE FUNCTION CALLERS
54.4 kernel lock_delay _mtx_lock_spin_cookie
18.0 kernel acpi_cpu_idle_mwait acpi_cpu_idle
by the way the acpi_cpu_idle is lower now but the mtx_lock_spin is high..
ok i run lockstat -x aggsize=4m sleep 10 > lock-type.txt
