gpu: nvgpu: Updated RPC to support copyback & callback
- Updated & added new parameter "bool is_copy_back" to
nvgpu_pmu_rpc_execute() to support copy back processed
RPC request from PMU to caller by passing parameter value
true & this blocks method till it receives ACK from PMU
for requested RPC.
- Added "struct rpc_handler_payload" to hold info
required for RPC handler like RPC buff address &
clear memory if copy back is not requested.
- Added define PMU_RPC_EXECUTE_CPB to support to copy back
processed RPC request from PMU to caller.
- Updated RPC callback handler support, crated memory &
assigned default handler if callback is not requested
else use callback parameters data to request to PMU.
- Added define PMU_RPC_EXECUTE_CB to support callback
- Updated pmu_wait_message_cond(), restricted condition
check to 8-bit instead 32-bit condition check.
