[laptop-discuss] [Fwd: GNOME Power Manager flash demo]

[James Cornell]

"10th or above" doesn't really help me, but I suspect it means  
Barcelona or above (4 core) as TSC support is missing in all prior and  
Sun doesn't want to put engineering efforts into "retrofitting" it on  
prior.  Only uniprocessor setups before Barcelona will be supported,  
single-core only.  All other operating systems except maybe NetBSD,  
ReactOS, and HaikuOS running on modern Turion64, Opteron and AMD64  
support PowerNOW, on both single and multiprocessor setups.  I find it  
extremely frustrating that 30-40% of the AMD units in use are not  
being supported by PowerNOW, especially K8 SMP setups like those  
offered by Sun.  I have an Ultra 20 M2 High-end and I'm pretty sure  
that suspend-to-ram, suspend-to-disk, and all other features were  
originally implemented for this model, but the lack of CPUFreq hurts  
the overall sustainability of Solaris as for those who run their  
machines constant, dynamic cpu frequency throttling is more cost  
reducing than suspending, some people work pseudo frequently with  
their machines and cannot have it suspend at predictable intervals of  
time.  Check mailing list archives I'm sure you'll find it buried  
regarding power management on Ultra 20.
