I don't quite understand. What am I looking for in top?

Here's the before and after:

before:

$ grep C /proc/acpi/processor/*/*
/proc/acpi/processor/CPU0/power:active state: C1
/proc/acpi/processor/CPU0/power:max_cstate: C8
/proc/acpi/processor/CPU0/power: *C1: type[C1]
promotion[--] demotion[--] latency[000] usage[00000000] duration[00000000000000000000]
/proc/acpi/processor/CPU1/power:active state: C1
/proc/acpi/processor/CPU1/power:max_cstate: C8
/proc/acpi/processor/CPU1/power: *C1: type[C1]
promotion[--] demotion[--] latency[000] usage[00000000] duration[00000000000000000000]

after:

grep C /proc/acpi/processor/*/*
/proc/acpi/processor/CPU0/power:active state: C1
/proc/acpi/processor/CPU0/power:max_cstate: C8
/proc/acpi/processor/CPU0/power: *C1: type[C1]

/proc/acpi/processor/CPU1/power:max_cstate: C8
/proc/acpi/processor/CPU1/power: *C1: type[C1]
