0x200 + n * 0x100 + 0x04 | 4 | Unknown |
0x200 + n * 0x100 + 0x24 | 4 | Scanout source X (in (0x100000 / 960) multiples) |
0x200 + n * 0x100 + 0x28 | 4 | Scanout source Y (in (0x100000 / 544) multiples) |
0x200 + n * 0x100 + 0x40 | 4 | Pixelformat (0x10 = A8B8G8R8) |
0x200 + n * 0x100 + 0x44 | 4 | Buffer width (aligned to 16) |
0x200 + n * 0x100 + 0x48 | 4 | Buffer height (aligned to 8) |
0x200 + n * 0x100 + 0x4C | 4 | Control register. bit 0 = disable plane? |
0x200 + n * 0x100 + 0x54 | 4 | Leftover stride |
0x200 + n * 0x100 + 0x58 | 4 | ?? |
0x200 + n * 0x100 + 0x60 | 4 | Vertical front porch |
0x200 + n * 0x100 + 0x64 | 4 | Vertical back porch |
0x200 + n * 0x100 + 0x68 | 4 | Horizontal front porch |
0x200 + n * 0x100 + 0x6C | 4 | Horizontal back porch |
0x200 + n * 0x100 + 0xA0 | 4 | Destination pixelformat |
0x200 + n * 0x100 + 0xA4 | 4 | Destination width |
0x200 + n * 0x100 + 0xA8 | 4 | Destination height |
0x200 + n * 0x100 + 0xC0 | 4 | Scanout source width (in (0x100000 / 960) multiples) |
0x200 + n * 0x100 + 0xC4 | 4 | Scanout source height (in (0x100000 / 544) multiples) |
0x200 + n * 0x100 + 0xC8 | 4 | Scanout destination X |
0x200 + n * 0x100 + 0xCC | 4 | Scanout destination Y |
0x200 + n * 0x100 + 0xD0 | 4 | Scanout destination width |
0x200 + n * 0x100 + 0xD4 | 4 | Scanout destination height |
Where n can be 0 and 1. n = 0 configures the plane for the CRTC 0 (OLED/LCD) scanout, and n = 1 configures the plane for the CRTC 1 (HDMI) scanout.
