30 | * This file gather function specific to RS600 which is the IGP of |
31 | * the X1250/X1270 family supporting intel CPU (while RS690/RS740 |
32 | * is the X1250/X1270 supporting AMD CPU). The display engine are |
33 | * the avivo one, bios is an atombios, 3D block are the one of the |
34 | * R4XX family. The GART is different from the RS400 one and is very |
35 | * close to the one of the R600 family (R600 likely being an evolution |
36 | * of the RS600 GART block). |
