For instance here's a snippet from the fedora 8 kernel 2.6.23.1-42.fc8: CPU: L1 I cache: 32K, L1 D cache: 32K CPU: L2 cache: 4096K CPU 0/0 -> Node 0 using mwait in idle threads. CPU: Physical Processor ID: 0 CPU: Processor Core ID: 0 CPU0: Thermal monitoring enabled (TM2) SMP alternatives: switching to UP code ACPI: Core revision 20070126 Using local APIC timer interrupts. APIC timer calibration result 12465172 Detected 12.465 MHz APIC timer. SMP alternatives: switching to SMP code Booting processor 1/2 APIC 0x1 Initializing CPU#1 Calibrating delay using timer specific routine.. 3988.84 BogoMIPS (lpj=1994422) CPU: L1 I cache: 32K, L1 D cache: 32K CPU: L2 cache: 4096K CPU 1/1 -> Node 0 CPU: Physical Processor ID: 0 CPU: Processor Core ID: 1 CPU1: Thermal monitoring enabled (TM2) Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz stepping 0a Brought up 2 CPUs So, there, as you can see ther kernle is pretty smart nowadays.
