voodoo3-agp

Provided by: voodoo3-agp
Class Hierarchy: conf-object → log-object → voodoo3-agp
Interfaces Implemented: log_object, event_poster, io_memory, pci_device
Description: The voodoo3-agp device implements the graphics device Voodoo3 (Avenger) from 3Dfx Interactive, Inc. It's very similar to the voodoo3 device, except that it connects to the AGP bus instead of the PCI bus. The device supports accelerated 2D and 3D graphics in multiple resolutions and color depths. The VGA core for this device is inherited from the VGA-PCI device.

Description: Display part of the voodoo3-agp framebuffer in the console window. fboffs is the starting offset into the 16 MB voodoo3 framebuffer. width and height are the pixel dimensions of the area to be shown. bpp (bits per pixel) specifies the format of the pixel data and can be one of 8, 16, 24 or 32 (defaults to current desktop color depth). stride is the byte offset between adjacent lines (defaults to width * bpp / 8).

<voodoo3-agp>.info
Synopsis: <voodoo3-agp>.info [verbose]
Description: Show information about the current voodoo3 state, for example the current resolution, color depth, desktop image offset etc. Currently the verbose flag has no function.

<voodoo3-agp>.ioreg
Synopsis: <voodoo3-agp>.ioreg register
Description: Print value in an IO register.

<voodoo3-agp>.redraw
Synopsis: <voodoo3-agp>.redraw
