MMIO Interfaces
| Name | Physical address |
|---|---|
| SceIftu0RegA (OLED FB) | 0xE5020000 |
| SceIftu0RegB | 0xE5021000 |
| SceIftuc0Reg | 0xE5022000 |
| SceIftu1RegA (HDMI FB) | 0xE5030000 |
| SceIftu1RegB | 0xE5031000 |
| SceIftuc1Reg | 0xE5032000 |
| SceIftu2Reg | 0xE5040000 |
It looks like the display controller has 4 overlay planes (Iftu0RegA, Iftu0RegB, Iftu1RegA, Iftu0RegB) and 1 cursor plane (Iftu2Reg)?

| 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 + 0x40 | 4 | Pixelformat (0x10 = A8B8G8R8) |
| 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.

| 0x04 | 4 | Control register. bit 0 = enable? |
| 0x10 | 4 | bit 0 = Enable Engine 0 (OLED/LCD) or Engine 1 (HDMI) |
| 0x20 | 4 | Control register 2? bit 2 = enable alpha/brightness |
