* gpu: nvgpu: add flag for over power monitoringThomas Fleury2017-01-31
| | | | | | | | | | | | | | | | On PG418, we hard code SW threshold table for over power monitoring. On PG419, there is a dedicated INA for over power monitoring. It is programmed in VBIOS devinit. Added a platform flag to indicate if devinit has already taken care of programming.

* gpu: nvgpu: Make driver rebind workAlex Waterman2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the GPU bind and rebind operations work when the driver is idle. This required two changes. 1. Reset the GPU before doing SW init for PCI GPUs. This clears the SW state which may be stale in the case of a rebind attempt. 2. Cleanup the interrupt enable/disables. Firstly there was one place where nvgpu would accidentally disable the stalling interrupt twice when the stalling interrupt and non-stalling interrupt are the same. Secondly make sure when exiting nvgpu that the interrupt enable/disables are balanced. Leaving the interrupt in the -1 disable state means that next time the driver runs interrupts never quite get enabled.

| | | | | | | | | | | | | | | | | | | | | | | | Handle possible asynchronous GPU driver shutdown more gracefully. This occurs when the GPU disappears from the PCI bus, for example, if it overheats or detects an over current event. Also add a preprocessor check to make sure that the gk20a_channel_cancel_pending_sema_waits() is always defined. In some builds CONFIG_SYNC is disabled but the gk20a_remove_support() code does not check for this.
