r128 - ATI Rage 128 video driver
r128 is an XFree86 driver for ATI Rage 128 based video cards. It con-
tains full support for 8, 15, 16 and 24 bit pixel depths, hardware
acceleration of drawing primitives, hardware cursor, video modes up to
1800x1440 @ 70Hz, doublescan modes (e.g., 320x200 and 320x240), gamma
correction at all pixel depths, a fully programming dot clock and
robust text mode restoration for VT switching.
The r128 driver supports all ATI Rage 128 based video cards including
the Rage Fury AGP 32MB, the XPERT 128 AGP 16MB and the XPERT 99 AGP
Please refer to XF86Config(5) for general configuration details. This
section only covers configuration details specific to this driver.
The driver auto-detects all device information necessary to initialize
the card. However, if you have problems with auto-detection, you can
VideoRam - in kilobytes
MemBase - physical address of the linear framebuffer
IOBase - physical address of the MMIO registers
ChipID - PCI DEVICE ID
In addition, the following driver Options are supported:
Option "SWcursor" "boolean"
Selects software cursor. The default is off.
Option "NoAccel" "boolean"
Enables or disables all hardware acceleration. The default is
to enable hardware acceleration.
Option "Dac6Bit" "boolean"
Enables or disables the use of 6 bits per color component when
in 8 bpp mode (emulates VGA mode). By default, all 8 bits per
color component are used. The default is off.
Option "VideoKey" "integer"
This overrides the default pixel value for the YUV video overlay
key. The default value is undefined.
Option "Display" "string"
Select display mode for devices which support flat panels. Sup-
ported modes are:
"FP" - use flat panel;
"CRT" - use cathode ray tube;
"Mirror" - use both FP and CRT;
"BIOS" - use mode as configured in the BIOS.
The default is FP.
The following Options are mostly important for non-x86 architectures:
Option "ProgramFPRegs" "boolean"
Enable or disable programming of the flat panel registers.
Beware that this may damage your panel, so use this at your own
risk. The default depends on the device.
Option "PanelWidth" "integer"
Option "PanelHeight" "integer"
Override the flat panel dimensions in pixels. They are used to
program the flat panel registers and normally determined using
the video card BIOS. If the wrong dimensions are used, the sys-
tem may hang.
Option "UseFBDev" "boolean"
Enable or disable use of an OS-specific framebuffer device
interface (which is not supported on all OSs). See fbdevhw(4)
for further information. Default: off.
Option "DMAForXv" "boolean"
Try or don't try to use DMA for Xv image transfers. This will
reduce CPU usage when playing big videos like DVDs, but may
cause instabilities. Default: off.
The following additional Options are supported:
Option "ShowCache" "boolean"
Enable or disable viewing offscreen cache memory. A development
debug option. Default: off.
