TDVFB(4) | Kernel Interfaces Manual | TDVFB(4) |
Since both Voodoo Graphics and Voodoo2 were originally designed as a 3D-only solutions, most boards do not have any kind of firmware. The tdvfb driver is able to do low level initialization (boot) of the board, which means that it can be used on all architectures and is truly machine independent. However, it also means that driver cannot detect automatically if the card is used as a console. The TDVFB_CONSOLE option is provided and should be set if the tdvfb driver is intended to be used as a console.

Video mode is hard-coded to 800x600 at 60Hz. Default bit depth for little endian machines is 16-bit, for big endian machines it is 32-bit. Resolution and depth should be selectable at least via kernel configuration file. It is not possible to detect what resolutions are supported by the monitor, since Voodoo Graphics and Voodoo2 have no DDC interface.
8-bit depth is not supported by the hardware. 16-bit depth is supported by the hardware and is the preferred depth, however it does not work correctly on big endian machines at the moment (this is a driver problem).
Sometimes the driver fails to detect RAMDAC.
