| | | | | | | | | | | | | | | | | | To test semaphore-related bugs with igpus, add a debugfs node called "disable_syncpoints" to override the "has_syncpoints" platform flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove including gk20a.h from pmu_gk20a.h. This causes a fallout as some #includes were missing. gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the include. Including mm_gk20a.h in gr_gp10b.h causes recursive include, as mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to remove the dependency. gr_ctx_gk20a.h used struct gk20a pointers, but did not forward declare it. Add a forward declaration. gr_gk20a.h uses dbg_session_gk20a, but was missing forward declaration. gr_gk20a.h did not include nvgpu.h but it uses preemption types from that header. Add include.

* 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.
