.SH DESCRIPTION
|
|
.B r128
|
|
is an __xservername__ 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, 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. Dualhead is supported on M3/M4
|
|
mobile chips.
|
|
.SH SUPPORTED HARDWARE
|
|
The
|
|
.B 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.
|
|
.SH CONFIGURATION DETAILS
|
|
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
|
|
details. This section only covers configuration details specific to this
|
|
driver.
|
|
.PP
|
|
The driver auto-detects all device information necessary to initialize
|
|
the card. However, if you have problems with auto-detection, you can
|
|
specify:
|
|
.PP
|
|
.RS 4
|
|
VideoRam - in kilobytes
|
|
.br
|
|
MemBase - physical address of the linear framebuffer
|
|
.br
|
|
IOBase - physical address of the MMIO registers
|
|
.br
|
|
ChipID - PCI DEVICE ID
|
|
.RE
|
|
.PP
|
|
In addition, the following driver
|
|
.B Options
|
|
are supported:
|
|
.TP
|
|
.BI "Option \*qSWcursor\*q \*q" boolean \*q
|
|
Selects software cursor. The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qNoAccel\*q \*q" boolean \*q
|
|
Enables or disables all hardware acceleration. The default is to
|
|
.B enable
|
|
hardware acceleration.
|
|
.TP
|
|
.BI "Option \*qDac6Bit\*q \*q" boolean \*q
|
|
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
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qVideoKey\*q \*q" integer \*q
|
|
This overrides the default pixel value for the YUV video overlay key.
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qDisplay\*q \*q" string \*q
|
|
Select display mode for devices which support flat panels. Supported modes are:
|
|
|
|
.B \*qFP\*q
|
|
- use flat panel;
|
|
|
|
.B \*qCRT\*q
|
|
- use cathode ray tube;
|
|
|
|
.B \*qMirror\*q
|
|
- use both FP and CRT;
|
|
|
|
.B \*qBIOS\*q
|
|
- use mode as configured in the BIOS.
|
|
|
|
The default is
|
|
.B FP.
|
|
|
|
.PP
|
|
The following
|
|
.B Options
|
|
are mostly important for non-x86 architectures:
|
|
.TP
|
|
.BI "Option \*qProgramFPRegs\*q \*q" boolean \*q
|
|
Enable or disable programming of the flat panel registers.
|
|
Beware that this may damage your panel, so use this
|
|
.B at your own risk.
|
|
The default depends on the device.
|
|
.TP
|
|
.BI "Option \*qPanelWidth\*q \*q" integer \*q
|
|
.TP
|
|
.BI "Option \*qPanelHeight\*q \*q" integer \*q
|
|
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.
|
|
.TP
|
|
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
|
|
Enable or disable use of an OS-specific framebuffer device interface
|
|
(which is not supported on all OSs). See fbdevhw(__drivermansuffix__)
|
|
for further information.
|
|
Default:
|
|
.BI on
|
|
for PowerPC,
|
|
.BI off
|
|
for other architectures.
|
|
.TP
|
|
.BI "Option \*qDMAForXv\*q \*q" boolean \*q
|
|
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.
|
|
|
|
.PP
|
|
The following additional
|
|
.B Options
|
|
are supported:
|
|
.TP
|
|
.BI "Option \*qShowCache\*q \*q" boolean \*q
|
|
Enable or disable viewing offscreen cache memory. A
|
|
development debug option. Default: off.
|
|
.TP
|
|
.BI "Option \*qVGAAccess\*q \*q" boolean \*q
|
|
Tell the driver if it can do legacy VGA IOs to the card. This is
|
|
necessary for properly resuming consoles when in VGA text mode, but
|
|
shouldn't be if the console is using radeonfb or some other graphic
|
|
mode driver. Some platforms like PowerPC have issues with those, and they aren't
|
|
necessary unless you have a real text mode in console. The default is
|
|
.B off
|
|
on PowerPC and SPARC and
|
|
.B on
|
|
on other architectures.
|
|
|
|
.PP
|
|
.B Dualhead Note:
|
|
The video BIOS on some laptops interacts strangely with dualhead.
|
|
This can result in flickering and problems changing modes on crtc2.
|
|
If you experience these problems try toggling your laptop's video
|
|
output switch (e.g., fn-f7, etc.) prior to starting X or switch to
|
|
another VT and back.
