Description
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.
It seems only one process can have rendering rights at a time: for example, trying to use this command with Home Menu active results in GSP module not responding to the command. This command likely blocks until the process already doing rendering uses GSP:ReleaseRight.
