* gpu: nvgpu: Base channel watchdog on gp_getTerje Bergstrom2017-01-30
| | | | | | | | | | | | | | | | | | Instead of checking if a job is complete, only check that channel is making progress by checking its gp_get is advancing. This will make the watchdog conservative. Previously a whole job had x seconds to complete. Now channel has x seconds to get host to consume each push buffer segment.

* gpu: nvgpu: add disable_syncpoints debugfs nodeKonsta Holtta2017-01-27
| | | | | | | | | | | | | | | | | | To test semaphore-related bugs with igpus, add a debugfs node called "disable_syncpoints" to override the "has_syncpoints" platform flag. This makes job synchronization use semaphores, for example. NVGPU_GPU_FLAGS_HAS_SYNCPOINTS is still reported in gpu characteristics if the platform supports that, because it is filled in during boot.

* gpu: nvgpu: Remove circular dependency in PMU includesTerje Bergstrom2017-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | When gpu host is executing a context, there should not be any calls to fecs that can change the current context in execution. For some reason legacy fmodels are calling fecs method to golden context restore while loading golden context for new channel. This call is not required and should not be called. Only first time during golden context creation, fecs methods like bind can be called and it is pretty safe to do.

* gpu: nvgpu: use HAL to set TSG timesliceThomas Fleury2017-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | Setting timeslice for virtualized case was not effective, because both ioctls NVGPU_TSG_IOCTL_SET_TIMESLICE and NVGPU_SCHED_IOCTL_TSG_SET_TIMESLICE were calling the native function to set TSG timeslice. - Fixed wrapper function to call HAL - Defined HAL function for "native" set TSG timeslice - Also, properly update timeout_us in TSG context, in virtualized case. This change also moves the min/max bounds checking for tsg timeslice into the native function implementation. There is no sysfs node for these parameters for vgpu, as RM server is ultimately responsible for this check.
