DESCRIPTION
r128 is an XFree86 driver for ATI Rage 128 based video
cards. It contains full support for 8, 15, 16 and 24 bit
pixel depths, hardware acceleration of drawing primitives,
hardware cursor, video modes up to 1800x1440 @ 70Hz, doub-
lescan 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.
SUPPORTED HARDWARE
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 8MB.
CONFIGURATION DETAILS
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 specify:
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 com-
ponent 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. Supported 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 regis-
ters. Beware that this may damage your panel, so use
this at your own risk. The default depends on the dev-
ice.
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 system 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.
