When flag is non-zero additional hardware initialization is done, in some cases this includes executing the hw-init function used for GSPGPU:ResetGpuCore. That function is only executed when a state field is value 0, after executing that function this field is set to value 1.

Only one process can have rendering rights at a time. When another process has those rights, this command blocks until the process with the rights uses GSP:ReleaseRight.
