[CPUFREQ] use dynamic debug instead of custom infrastructure

2011-05-04T15:50:57Z

With dynamic debug having gained the capability to report debug messages also during the boot process, it offers a far superior interface for debug messages than the custom cpufreq infrastructure. As a first step, remove the old cpufreq_debug_printk() function and replace it with a call to the generic pr_debug() function. How can dynamic debug be used on cpufreq? You need a kernel which has CONFIG_DYNAMIC_DEBUG enabled. To enabled debugging during runtime, mount debugfs and $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control for debugging the complete "cpufreq" module. To achieve the same goal during boot, append ddebug_query="module cpufreq +p" as a boot parameter to the kernel of your choice.

[CPUFREQ] Fix _OSC UUID in pcc-cpufreq

2011-05-04T15:50:56Z

UUID needs to be written out the way it is described in Sec 18.5.124 of ACPI 4.0a Specification. Platform firmware's use of this UUID/_OSC is optional, which is why we didn't notice this bug earlier. Signed-off-by: Naga Chumbalkar Signed-off-by: Dave Jones Cc: stable@kernel.org

[CPUFREQ] powernow-k8: The table index is not worth displaying

2011-03-16T21:54:31Z

and it also is misleading due to another message above which makes the index look like it is the CPU. https://bugzilla.kernel.org/show_bug.cgi?id=24562 Signed-off-by: Thomas Renninger Signed-off-by: Dave Jones CC: cpufreq@vger.kernel.org

[CPUFREQ] pcc-cpufreq: don't load driver if get_freq fails during init.

2011-03-09T17:33:15Z

Return 0 on failure. This will cause the initialization of the driver to fail and prevent the driver from loading if the BIOS cannot handle the PCC interface command to "get frequency". Otherwise, the driver will load and display a very high value like "4294967274" (which is actually -EINVAL) for frequency: # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 4294967274 Signed-off-by: Naga Chumbalkar CC: stable@kernel.org Signed-off-by: Dave Jones

[CPUFREQ] Fix another notifier leak in powernow-k8.

Do the notifier registration later, so we don't have to worry about freeing it if we fail the msr allocation. Signed-off-by: Dave Jones
