Hi Sathvik,
The cpudrv drviver did not load on your system.
cpudrv creates these kstats.
Your test machine is a Pentium 4:
Intel(r) Pentium(r) 4 CPU 2.40GHz
I suspect OpenSolaris does not support Speedstep on P4.
Lets look at the code:
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/io/cpudrv/speedstep.c#246
boolean_t
speedstep_supported(uint_t family, uint_t model)
{
struct cpuid_regs cpu_regs;
uint64_t reg;
/* Required features */
if (!(x86_feature & X86_CPUID) ||
!(x86_feature & X86_MSR)) {
return (B_FALSE);
}
/*
* We only support family/model combinations which
* are P-state TSC invariant.
*/
if (!((family == 0xf && model >= 0x3) ||
(family == 0x6 && model >= 0xe))) {
return (B_FALSE);
}
If I am not mistaken Intel Family=f model=3 is Prescott which is
later than P4. P4 and earlier are not supported.
Regards,
Bill
