vga_pci

Provided by

vga-pci

Class Hierarchy

conf-object → log-object → vga_pci

Interfaces Implemented

log_object, event_poster, io_memory, pci_device

Description

The VGA-PCI device is identical to the VGA device except it connects to the PCI bus instead of the ISA bus. This functionality of this device can also be inherited by more advanced graphic devices such as the Voodoo3 device. Limitations: Not all possible video modes are tested. The CGA Compatibility modes are not yet supported. Different character maps are not yet supported. Read Mode 1 is not yet implemented. Panning is not supported. Spilt Screen is not supported. Blinking text is not supported. Blinking color in video mode 0xf is not supported. Underlining in MDA compatibility mode is not supported. Extend ninth bit in text mode is not implemented.

Command Descriptions

<vga_pci>.info

Synopsis

<vga_pci>.info

Description

Print information about the device registers.

<vga_pci>.redraw

Synopsis

<vga_pci>.redraw

Description

This command sends the current frame buffer contents of the simulated video device to the graphics console. If a simulated cursor is active, it is updated as well.
