The first batch of patches was posted here:
They're now merged in RMK's devel-stable branch and also available via
the linux-next tree.
So here's the second set of patches towards a fully functional and
production quality switcher solution, establishing a landmark to compare
against for any scheduler based solution meant to eventually surpass the
switcher in the mainline kernel.
Those patches are also available here:
This set is divided in 3 groups:
Patches 1 to 3 are needed for proper interaction and synchronization with
the cpufreq companion driver that will be posted separately.
Patches 4 to 9 are providing significant switch latency and efficiency
improvements and are purely for optimization purposes.
Patches 10 to 13 are for switch event tracing.
Here's the diffstat:
