NetBSD 4.0.1 reports useful information about CPUs on boot, as in
cpu0 at mainbus0: apid 0 (boot processor)
cpu0: Intel Pentium 4 (686-class), 2806.50 MHz, id 0xf29
cpu0: features bfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features bfebfbff<PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX>
cpu0: features bfebfbff<FXSR,SSE,SSE2,SS,HTT,TM,SBF>
cpu0: features2 4400<CID,xTPR>
cpu0: "Intel(R) Pentium(R) 4 CPU 2.80GHz"
cpu0: I-cache 12K uOp cache 8-way, D-cache 8 KB 64B/line 4-way
cpu0: L2 cache 512 KB 64B/line 8-way
cpu0: ITLB 4K/4M: 128 entries
cpu0: DTLB 4K/4M: 64 entries
cpu0: using thermal monitor 1
cpu0: calibrating local timer
cpu0: apic clock running at 133 MHz
cpu0: 16 page colors
NetBSD 5.1 is much less helpful; on the same hardware, it says only
cpu0 at mainbus0 apid 0: Intel 686-class, 2806MHz, id 0xf29
Is there any way to get 5.1 to cough up anything more detailed about
the CPU(s) in use? I find it hard to believe losing all that
information could be considered an improvement, so I assume I'm just
missing something. A few bits are available from sysctl under the
machdep tree, but very far from everything 4.0.1 reports.
