Hello,
apparently powernow on Opteron quad-core is not recognised; when
I kldload cpufreq (leaving it out of kernel) I get :
pci0: driver added
pci1: driver added
pci2: driver added
pci3: driver added
pci4: driver added
pci5: driver added
pci6: driver added
found-> vendor=0x9005, dev=0x0285, revid=0x00

powerspec 2 supports D0 D1 D3 current D0
MSI supports 2 messages, 64 bit
pci0:6:14:0: reprobing on driver added
pci7: driver added
pci8: driver added
pci9: driver added
pci10: driver added
but no dev.cpu.0.freq* showing up.
When I dig up the by me so beloved good old acpi_ppc it says :
cpu0: Px state: P0, 2200MHz, 28000mW, 19us, 19us
cpu0: Px state: P1, 2000MHz, 26250mW, 19us, 19us
cpu0: Px state: P2, 1700MHz, 23750mW, 19us, 19us
cpu0: Px state: P3, 1400MHz, 21250mW, 19us, 19us
cpu0: Px state: P4, 1100MHz, 18750mW, 19us, 19us
cpu0: Px method: Unknown, disabled
This box will probably stay at my office for a while and I'd be glad to
provide more information.
Best, Arno
