https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218262 --- Comment #6 from Greg V <greg@unrelenting.technology> --- Created attachment 186809 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D186809&action= =3Dedit zenstate.c Okay, it's definitely overclocked, just ran Cinebench R15 under Wine, got 1= 755 points. (same 3.9GHz clock in Windows 10 gives me ~1715, 3.0GHz is significantly less). Here's the interesting bit from the AMD docs though: "This field provides t= he=20 frequency component of the current non-boosted P-state of the core". I guess "non-boosted" means "not ever returning P0"?! How is it providing "the frequency component" if it returns the number of t= he P-state?! This documentation makes ZERO sense. Also, here's a tiny program that sets P-state 0 from userspace via cpuctl, = it's easier to experiment with this than recompiling the kernel and stuff. --=20 You are receiving this mail because: You are the assignee for the bug.=
