Offset | Size | Description |
---|---|---|
0x000 | 4 | Control register: bit 0 = enable?, bit 2 = ??, bit 3 = ?? |
0x004 | 4 | CRTC mask: bit 0 = enable scanout to engine/CRTC of OLED/LCD, bit 1 = enable scanout to engine/CRTC of HDMI |
0x090 | 4 | Brightness value (or alpha?) |
0x0A4 | 4 | Control? (bit 0 = don't use the brightness value) |
0x200 + n * 0x100 + 0x00 | 4 | Physical address |
0x200 + n * 0x100 + 0x04 | 4 | Unknown |

0x200 + n * 0x100 + 0x44 | 4 | Width (aligned to 16) |
0x200 + n * 0x100 + 0x48 | 4 | Height (aligned to 8) |
0x200 + n * 0x100 + 0x4C | 4 | ?? |
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 + 0xC0 | 4 | Scanout source X (in 16.16 fixed point format) |
0x200 + n * 0x100 + 0xC4 | 4 | Scanout source Y (in 16.16 fixed point format) |
0x200 + n * 0x100 + 0xC8 | 4 | Scanout source height (in 16.16 fixed point format) |
0x200 + n * 0x100 + 0xCC | 4 | Scanout source width (in 16.16 fixed point format) |
0x200 + n * 0x100 + 0xD0 | 4 | ?? |
Where n can be 0 and 1. n = 0 configures the CRTC 0 (OLED/LCD) scanout, n = 1 configures the CRTC 1 (HDMI) scanout.
