* gpu: nvgpu: gk20a: check the return value of gk20a_channel_busyKerwin Wan2015-03-18
| | | | | | | | | | | | | | gk20a_channel_busy is called to host gpu so that gk20a can be accessed. But it may return error like if gpu fails to be powered on. Always check the return value of gk20a_channel_busy to avoid illegal access to gk20a.

* gpu: nvgpu: gk20a: allow syncpt free at channel_unbind()Deepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | Add infrastructure to allow freeing gpu channels' syncpts at channel_unbind() Currently, we free the syncpt at channel_free() only. But we can free the syncpt when channel becomes idle. When we do channel_unbind(), channel cannot be scheduled and hence we can destroy its syncpt. Channel will request again for new syncpt when it has new work to do. This feature will be enabled with boolean flag syncpt_aggressive_destroy Bug 1305024 Change-Id: Ib498e2c371e36ffc1430d4f95f2780b4c587e43e Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/395153 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: Power on platform deps for wfiArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | Currently gk20a_channel_idle() drops pm_runtime references to gk20a and then drops platform dependencies. As we usually delay powering down gk20a, we may end up to case where the platform dependencies are turned off at the moment we start powering down gk20a. Power off sequence may use platform dependencies for informing completion of the last work, wait-for-idle, and therefore we may simply drop the information about job completion. This patch adds missing calls to power up platform dependencies for the time we submit the last work.
