>Synopsis: hw.setperf=-700 by default on Dell C5220
>Category: kernel
>Environment:
System : OpenBSD 5.5
Details : OpenBSD 5.5 (GENERIC.MP) #315: Wed Mar 5 09:37:46 MST
2014
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
hw.setperf is set to -700 by default on a Dell PowerEdge C5220.
Reading its explicit value makes it change to 0.
This doesn't appear to cause any problem, but I'm not sure it should
be a negative number which behaves this way, so I'd rather report
it just in case. Sorry if it's just noise.
