0x1EF018E0
| Register address | Description |
|---|---|
| 0x1EF018E0 | Buffer Size>>3 |
| 0x1EF018E8 | Buffer physical address>>3 |
| 0x1EF018F0 | Writing value 1 here triggers GPU processing for the specified buffer |
These 3 registers are used by GX command 1. This is used for GPU commands.
0x1EF00010
| Register address | Description |
|---|---|
| 0x1EF000X0 | Buffer physical address>>3 |
| 0x1EF000X4 | Associated buffer physical address>>3 |
| 0x1EF000X8 | Buffer size |
| 0x1EF000XC | The low u16 for this register is overwritten by the GX command u16 parameter |
These registers are used by GX command 2. 0x1EF00010 is used for the GX command buf0 parameters, while 0x1EF00020 is used for the GX command buf1 parameters.
0x1EF00C00
| Register address | Description |
|---|---|
| 0x1EF00C00 | Input framebuffer physical address>>3 |
| 0x1EF00C04 | Output framebuffer physical address>>3 |
| 0x1EF00C08 | Output framebuffer dimensions, used with cmd3 |
| 0x1EF00C0C | Input framebuffer dimensions, used with cmd3 |
| 0x1EF00C10 | Flags, used with cmd3 and cmd4. |
| 0x1EF00C14 | GSP module writes value 0 here prior to writing to 0x1EF00C18, for cmd3. |
| 0x1EF00C18 | Writing value 1 here triggers GPU processing for the specified buffers. |
| 0x1EF00C20 | Unknown, used with cmd4 |
| 0x1EF00C24 | Unknown, used with cmd4 |
| 0x1EF00C28 | Unknown, used with cmd4 |
These registers are used by GX command 3 and 4. For cmd4, *0x1EF00C18 |= 1 is used instead of just writing value 1. The dimensions fields seem to use the same format as LCD register 0x1EF00X5C.

| 11-0 | ? |
| 12 | Color format related? |
| 23-13 | ? |
| 24 | When this is set, the actual framebuffer width is input width>>1. |
