* gpu: nvgpu: sim: avoid fecs golden context restoreseshendra Gadagottu2017-01-16
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | When kernel adds patches to a context, kernel needs to update the patch count in order for FECS to pick up the new patches. Previously patching was done only at the context creation time. Now patching is used also when changing preemption mode, but the patches did not take effect due to not updating count. Update patch count every time we end patching of a context.
