Q.
I see only C0, C1, and C2. Why don't the other C-states show?
A.
It's mostly a BIOS thing. Some BIOS hide C3/C4 when on AC power, and
others show only C3 which is really a C4 underneath when on battery.
Note that the 'max_cstate:C8' value in /proc/acpi/processor/*/power
tells the maximum number of C-states the Linux kernel can handle, not
the number of C-states implemented in your hardware.
