I'm running linux 2.6.23 on the Portwell PEB-2737 board based on the Intel Atom Z510 processor.
It seems, that this board does not support the ACPI-based processor perfomance control, so I want to modify the speedstep-centrino driver (arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c) to support the Atom Z510 processor. The frequency/voltage table is needed for it, but there is only min/max frequency values in the Z510 datasheet (319535). Does this CPU support the intermediate frequency/voltage values? If yes, where I can find it?
