2011-09-06video: tegra: dc: fake input deviceJon McCaffrey
Bug 855811 For smoothness and rate-limiting, it is useful to synchronize input events to flip. This patch adds a fake input device that emits an event on each vsync. This allows the Android input framework, which has significant infrastructure to monitor input devices in particular, to be notified of vsync events. Because there is no input event type/code for this behavior, we use an undocumented protocol of emitting a single MSC_RAW type event with scan-code 1. We also do not register ourselves for any other buttons/keys, which should prevent our device node from being confused with other input types.

2011-09-01ARM: tegra: power: Tune Tegra3 hotplug algorithmAlex Frid
- Account for EDP affect on total available MIPS when bringing on-line (removing off-line) new cpu core. Add multi-core overhead (in percent) as a parameter - set by default to 10%. - Add balance level parameter: level value (in percent) defines minimum speed ratio used by hotplug algorithm to determine if current CPU cores are balanced, so that another core may be brought on-line. By default set to 75% Added tunables: /sys/module/cpu_tegra3/parameters/mp_overhead /sys/module/cpu_tegra3/parameters/balance_level Bug 865176 Bug 867186 Change-Id: I6f2e175e0b5ed14c4b85794949c1e65d0e7f4a36 Reviewed-on: http://git-master/r/49772 Reviewed-by: Scott Williams <scwilliams@nvidia.com> Reviewed-by: Peter Boonstoppel <pboonstoppel@nvidia.com> Tested-by: Peter Boonstoppel <pboonstoppel@nvidia.com> Tested-by: Aleksandr Frid <afrid@nvidia.com> Reviewed-by: Yu-Huan Hsu <yhsu@nvidia.com> Reviewed-by: Diwakar Tundlam <dtundlam@nvidia.com>
