| 363 | * intel_init_bios - initialize VBIOS settings & find VBT |
| 364 | * @dev: DRM device |
| 365 | * |
| 366 | * Loads the Video BIOS and checks that the VBT exists. Sets scratch registers |
| 367 | * to appropriate values. |
| 368 | * |
| 369 | * VBT existence is a sanity check that is relied on by other i830_bios.c code. |
| 370 | * Note that it would be better to use a BIOS call to get the VBT, as BIOSes may |
| 371 | * feed an updated VBT back through that, compared to what we'll fetch using |
| 372 | * this method of groping around in the BIOS data. |
| 373 | * |
| 374 | * Returns 0 on success, nonzero on failure. |
