* 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>
