The Voodoo2 has 16bpp acceleration and the driver provides accelerated versions of most operations except angled lines and stipples. Accelerated alpha blending with the Render extension is also supported as is DGA.
This driver supports 16bpp modes currently. The video hardware supports image conversion from 24bpp to 16bpp but the hardware is 16bpp only.
The Voodoo 1 series cards can go up to 800x600 resolution while the Voodoo 2 can reach 1024x768 providing it has at least 2Mb of frame buffer memory. 1024x768 2D mode does not require two cards configured in scan-line interleave mode (SLI).
Multihead and Xinerama configurations are supported. SLI configurations will be treated as multiple video cards.
Limited support for DPMS screen saving is available. The "standby" and "suspend" modes are just painting the screen black. The "off" mode turns the Voodoo board off and thus works correctly.
This driver does not support a virtual screen size different from the display size. This is a hardware limitation. 3D rendering is also not supported.
The following driver Options are supported:
- Option "ShadowFB" "boolean"
- Enables a shadow buffer in main memory. This turns off acceleration but for otherwise unaccelerated operations can improve performance materially. Default: off for voodoo2, on for voodoo1.
- Option "NoAccel" "boolean"
- Disables acceleration if set. Unless debugging this option should only be set if ShadowFB is enabled. Default: off for voodoo2, on for voodoo1.
