* gpu: nvgpu: Check for dead GPUAlex Waterman2016-12-19
| | | | | | | | | | | | | | | | | | | | | Check if the GPU is present after each register read. If the a register read returns 0xffffffff then it's possible the GPU has fallen off the bus for some reason or another. However, to confirm that a register read is due to a dead GPU vs just a 0xffffffff being returned by happenstance the chip ID register is read which should never return 0xffffffff. If that read returns 0xffffffff as well then certainly the GPU is dead.

* gpu: nvgpu: Use struct to hold gk20a pointerAlex Waterman2016-12-19
| | | | | | | | | | | | | | | | | | | | | | The private_data field in the file pointer passed to release() for channels originally pointed directly to the referenced channel. The problem with this is that when the driver is killed and the channel mmeory is freed that pointer becomes invalid. The necessity of that channel is to get access to the gk20a struct that owns the channel. This can instead be accomplished by making a new private data struct that has a pointer to the gk20a struct directly instead of requiring the channel to be valid. This lets the release() function work even if the channels are gone (though in such cases the release function doesn't do very much).
