Hi all,

So with my Core i5 520 M (2 physical cores, 4 logical cores):

* 2.6.32.15 (ubuntu), 2.6.35.7 (kernel.org), 2.6.35.7 (kernel.org + 2 patchs) :

- Values of /sys/devices/system/cpu/cpu*/cpufreq/affected_cpus are : "0", "1",
"2" and "3" respectively for cpu0, cpu1, cpu2 and cpu3.

- Output of /sys/devices/system/cpu/cpu*/cpufreq/related_cpus is always : "0 1
2 3"

No problem.

* 2.6.35.7 (kernel.org + 2 patchs) with and without boot parameter
"processor.disable_hw_coord=1" :

- Output of /sys/devices/system/cpu/cpu*/cpufreq/shared_type is always :
1

Always default value 1 (CPUFREQ_SHARED_TYPE_HW) : so, Thomas, according to what
you said, there is something wrong here...

- cpufreq-info returns the same result as before (lowest freq).
- /sys/devices/system/cpu/cpufreq/ondemand/up_threshold is 95 by default.
- Lower the up_threshold has no effect for me.
