This page describes the structure of the GSP [[GSPGPU:RegisterInterruptRelayQueue|shared]] memory. GX commands and framebuffer info is stored here, and other unknown data. After writing the command data to GSP shared memory, [[GSPGPU:TriggerCmdReqQueue|TriggerCmdReqQueue]] must be used to trigger GSP processing for the command.

The command buffer is located at sharedmem + 0x800 + [[GSPGPU:RegisterInterruptRelayQueue|threadindex]]*0x200.
The command buffer is located at sharedmem + 0x800 + [[GSPGPU:RegisterInterruptRelayQueue|threadindex]]*0x200. After writing the command data to shared memory, [[GSPGPU:TriggerCmdReqQueue|TriggerCmdReqQueue]] must be used to trigger GSP processing for the command when the total commands field is value 1.
