Hi! I tried cpufreq on hp omnibook with athlon4 cpu... Its interesting: It works *in addition* to ACPI throttling. That means I can slow it down to 4% of top speed. Documentation/cpufreq should probably be renamed to Doc*/cpufreq.txt. Kernel says: powernow: AMD K7 CPU detected. powernow: PowerNOW! Technology present. Can scale: frequency and voltage. powernow: Found PSB header at c00f7ab0 powernow: Table version: 0x12 powernow: Flags: 0x0 (Mobile voltage regulator) powernow: Settling Time: 100 microseconds. powernow: Has 14 PST tables. (Only dumping ones relevant to this CPU). powernow: PST:2 (@c00f7ae4) powernow: cpuid: 0x761 fsb: 100 maxFID: 0xc startvid: 0xc powernow: FID: 0x10 (3.0x [300MHz]) VID: 0xc (1.400V) powernow: FID: 0x4 (5.0x [500MHz]) VID: 0xc (1.400V) powernow: FID: 0x6 (6.0x [600MHz]) VID: 0xc (1.400V) powernow: FID: 0x8 (7.0x [700MHz]) VID: 0xc (1.400V) powernow: FID: 0xc (9.0x [900MHz]) VID: 0xc (1.400V) First it claims it can scale voltage, then I see I can only use 1.4V. Too bad for me (and my batteries ;-)... Pavel -- When do you have a heart between your knees?
