* gpu: nvgpu: add platform specific get_iova_addr()Deepak Nibade2015-04-04

* tegra: gpu: disable touch boost for gpuSeshendra Gadagottu2015-04-04
| | | | | | | | | | | | | | | Gpu boosting with input events is causing more gpu power consumption than required. To avoid this, touch boot for gpu is disabled by not registering gpu device for cfboost frame work. Current rail gate entry/exit latencies are fast enough to give smooth user experience.

* gpu: nvgpu: add flag for CAR reset in do_idle()Deepak Nibade2015-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add "force_reset" flag to __gk20a_do_idle() For real world use cases like VPR resizing, we cannot wait for railgate_delay (which is 500 mS). Hence use CAR reset for this use case. (this is done via gk20a_do_idle() API with force_reset = true) Some of the test cases make use of sysfs "force_idle" and they expect GPU to be into really railgated state and not in CAR reset. Hence when called from sysfs, set force_reset = false. When global flag "force_reset_in_do_idle" is set, it will override local flags and force CAR reset case. This is desired in cases where railgating is not enabled Also, set force_reset_in_do_idle = false for GM20B since railgating has been enabled for GM20B Bug 1592997 Change-Id: I6c5af2977c7211ef82551a86a7c1eb51b8ccee60 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/711615 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
