This is the "new and improved" version of the patch
that was sent out earlier this week. Thanks for all the
(lkml subject line reference for previous thread -
"Dynamic cpufreq governor and updates to ACPI P-state driver")
The changes from the previous version:
1) dynamic cpufreq governor changes completely separated
from the updates to acpi P-state driver. These patches only
deal with dynamic cpufreq governor. Separate patch will be
sent out later to cover acpi updates.
2) New name for this cpufreq driver "cpufreq_ondemand"
(Thanks to Pavel for the name)
3) Miscellaneous bugfixes and changes based on the review comments
4) And introduction of tuning knobs, where advanced user can tune
the cpufreq_ondemand behaviour.
(Thanks to Dominik for helping me with this)
Sampling_rate, down_threshold, up_threshold are currently exported.
More advanced user who wants to change the algorithm itself, can
take the base infrastructure from this driver and come up with a
new/optimized frequency switching algorithm, as this driver is GPLed
Patch contents (patches against 2.6.0-test8):
ondemand1.patch - 'unit' related bugfixes in drivers.
ondemand2.patch - basic cpufreq_ondemand governor, with some changes
since the last time.
ondemand3.patch - Adding sysfs interface for cpufreq_ondemand
tunables and making sysfs access by cpufreq governors safe against
removal of the underlying module (from Dominik).
