.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.
|
|
.br
|
|
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.
|
|
.br
|
|
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.
|
|
.br
|
|
The default value is
|
|
.B 0x1E.
|
|
.TP
|
|
.BI "Option \*qScalerWidth\*q \*q" integer \*q
|
|
This sets the overlay scaler buffer width. Accepted values range from 1024 to
|
|
2048, divisible by 64, values other than 1536 and 1920 may not make sense
|
|
though. Should be set automatically, but noone has a clue what the limit is
|
|
for which chip. If you think quality is not optimal when playing back HD video
|
|
(with horizontal resolution larger than this setting), increase this value, if
|
|
you get an empty area at the right (usually pink), decrease it. Note this only
|
|
affects the "true" overlay via xv, it won't affect things like textured video.
|
|
.br
|
|
The default value is either 1536 (for most chips) or 1920.
|
|
.TP
|
|
.BI "Option \*qAGPMode\*q \*q" integer \*q
|
|
Set AGP data transfer rate.
|
|
(used only when DRI is enabled)
|
|
.br
|
|
1 \-\- 1x (before AGP v3 only)
|
|
.br
|
|
2 \-\- 2x (before AGP v3 only)
|
|
.br
|
|
4 \-\- 4x
|
|
.br
|
|
8 \-\- 8x (AGP v3 only)
|
|
.br
|
|
others \-\- invalid
|
|
.br
|
|
The default is to
|
|
.B leave it unchanged.
|
|
.TP
|
|
.BI "Option \*qAGPFastWrite\*q \*q" boolean \*q
|
|
Enable AGP fast writes. Enabling this is frequently the cause of
|
|
instability. Used only when the DRI is enabled. If you enable
|
|
this option you will get *NO* support from developers.
|
|
.br
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qBusType\*q \*q" string \*q
|
|
Used to replace previous ForcePCIMode option.
|
|
Should only be used when driver's bus detection is incorrect
|
|
or you want to force a AGP card to PCI mode. Should NEVER force
|
|
a PCI card to AGP bus.
|
|
.br
|
|
PCI \-\- PCI bus
|
|
.br
|
|
AGP \-\- AGP bus
|
|
.br
|
|
PCIE \-\- PCI Express (falls back to PCI at present)
|
|
.br
|
|
(used only when DRI is enabled)
|
|
.br
|
|
The default is
|
|
.B auto detect.
|
|
.TP
|
|
.BI "Option \*qDDCMode\*q \*q" boolean \*q
|
|
Force to use the modes queried from the connected monitor.
|
|
.br
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qDisplayPriority\*q \*q" string \*q
|
|
.br
|
|
Used to prevent flickering or tearing problem caused by display buffer underflow.
|
|
.br
|
|
AUTO \-\- Driver calculated (default).
|
|
.br
|
|
BIOS \-\- Remain unchanged from BIOS setting.
|
|
Use this if the calculation is not correct
|
|
for your card.
|
|
.br
|
|
HIGH \-\- Force to the highest priority.
|
|
Use this if you have problem with above options.
|
|
This may affect performance slightly.
|
|
.br
|
|
The default value is
|
|
.B AUTO.
|
|
.TP
|
|
.BI "Option \*qColorTiling\*q \*q" "boolean" \*q
|
|
Frame buffer can be addressed either in linear or tiled mode. Tiled mode can provide
|
|
significant performance benefits with 3D applications, for 2D it shouldn't matter
|
|
much. Tiling will be disabled if the virtual x resolution exceeds 2048 (3968 for R300
|
|
and above), if option
|
|
.B UseFBDev
|
|
is used, or (if DRI is enabled) the drm module is too old.
|
|
.br
|
|
If this option is enabled, a new dri driver is required for direct rendering too.
|
|
.br
|
|
Color tiling will be automatically disabled in interlaced or doublescan screen modes.
|
|
.br
|
|
The default value is
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qIgnoreEDID\*q \*q" boolean \*q
|
|
Do not use EDID data for mode validation, but DDC is still used
|
|
for monitor detection. This is different from NoDDC option.
|
|
.br
|
|
The default value is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qPanelSize\*q \*q" "string" \*q
|
|
Should only be used when driver cannot detect the correct panel size.
|
|
Apply to both desktop (TMDS) and laptop (LVDS) digital panels.
|
|
When a valid panel size is specified, the timings collected from
|
|
DDC and BIOS will not be used. If you have a panel with timings
|
|
different from that of a standard VESA mode, you have to provide
|
|
this information through the Modeline.
|
|
.br
|
|
For example, Option "PanelSize" "1400x1050"
|
|
.br
|
|
The default value is
|
|
.B none.
|
|
.TP
|
|
.BI "Option \*qEnablePageFlip\*q \*q" boolean \*q
|
|
Enable page flipping for 3D acceleration. This will increase performance
|
|
but not work correctly in some rare cases, hence the default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qForceMinDotClock\*q \*q" frequency \*q
|
|
Override minimum dot clock. Some Radeon BIOSes report a minimum dot
|
|
clock unsuitable (too high) for use with television sets even when they
|
|
actually can produce lower dot clocks. If this is the case you can
|
|
override the value here.
|
|
.B Note that using this option may damage your hardware.
|
|
You have been warned. The
|
|
.B frequency
|
|
parameter may be specified as a float value with standard suffixes like
|
|
"k", "kHz", "M", "MHz".
|
|
.TP
|
|
.BI "Option \*qRenderAccel\*q \*q" boolean \*q
|
|
Enables or disables hardware Render acceleration. This driver does not
|
|
support component alpha (subpixel) rendering. It is only supported on
|
|
Radeon series up to and including 9200 (9500/9700 and newer
|
|
unsupported). The default is to
|
|
.B enable
|
|
Render acceleration.
|
|
.TP
|
|
.BI "Option \*qAccelMethod\*q \*q" "string" \*q
|
|
Chooses between available acceleration architectures. Valid options are
|
|
.B XAA
|
|
and
|
|
.B EXA.
|
|
XAA is the traditional acceleration architecture and support for it is very
|
|
stable. EXA is a newer acceleration architecture with better performance for
|
|
the Render and Composite extensions, but the rendering code for it is newer and
|
|
possibly unstable. The default is
|
|
.B XAA.
|
|
.TP
|
|
.BI "Option \*qAccelDFS\*q \*q" boolean \*q
|
|
Use or don't use accelerated EXA DownloadFromScreen hook when possible (only
|
|
when Direct Rendering is enabled, e.g.).
|
|
Default:
|
|
.B off
|
|
with AGP due to issues with GPU->host transfers with some AGP bridges,
|
|
.B on
|
|
otherwise.
|
|
.TP
|
|
.BI "Option \*qFBTexPercent\*q \*q" integer \*q
|
|
Amount of video RAM to reserve for OpenGL textures, in percent. With EXA, the
|
|
remainder of video RAM is reserved for EXA offscreen management. Specifying 0
|
|
results in all offscreen video RAM being reserved for EXA and only GART memory
|
|
being available for OpenGL textures. This may improve EXA performance, but
|
|
beware that it may cause problems with OpenGL drivers from Mesa versions older
|
|
than 6.4. With XAA, specifying lower percentage than what gets reserved without
|
|
this option has no effect, but the driver tries to increase the video RAM
|
|
reserved for textures to the amount specified roughly.
|
|
Default:
|
|
.B 50.
|
|
.TP
|
|
.BI "Option \*qDepthBits\*q \*q" integer \*q
|
|
Precision in bits per pixel of the shared depth buffer used for 3D acceleration.
|
|
Valid values are 16 and 24. When this is 24, there will also be a hardware
|
|
accelerated stencil buffer, but the combined depth/stencil buffer will take up
|
|
twice as much video RAM as when it's 16.
|
|
Default:
|
|
.B The same as the screen depth.
|
|
.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:
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qSubPixelOrder\*q \*q" "string" \*q
|
|
Force subpixel order to specified order.
|
|
Subpixel order is used for subpixel decimation on flat panels.
|
|
.br
|
|
NONE \-\- No subpixel (CRT like displays)
|
|
.br
|
|
RGB \-\- in horizontal RGB order (most flat panels)
|
|
.br
|
|
BGR \-\- in horizontal BGR order (some flat panels)
|
|
|
|
.br
|
|
This option is intended to be used in following cases:
|
|
.br
|
|
1. The default subpixel order is incorrect for your panel.
|
|
.br
|
|
2. Enable subpixel decimation on analog panels.
|
|
.br
|
|
3. Adjust to one display type in dual-head clone mode setup.
|
|
.br
|
|
4. Get better performance with Render acceleration on
|
|
digital panels (use NONE setting).
|
|
.br
|
|
The default is
|
|
.B NONE
|
|
for CRT,
|
|
.B RGB
|
|
for digital panels
|
|
.TP
|
|
.BI "Option \*qDynamicClocks\*q \*q" boolean \*q
|
|
Enable dynamic clock scaling. The on-chip clocks will scale dynamically
|
|
based on usage. This can help reduce heat and increase battery
|
|
life by reducing power usage. Some users report reduced 3D performance
|
|
with this enabled. The default is
|
|
.B 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.
|
|
.TP
|
|
.BI "Option \*qReverseDDC\*q \*q" boolean \*q
|
|
When BIOS connector informations aren't available, use this option to
|
|
reverse the mapping of the 2 main DDC ports. Use this if the X serve
|
|
obviously detects the wrong display for each connector. This is
|
|
typically needed on the Radeon 9600 cards bundled with Apple G5s. The
|
|
default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qLVDSProbePLL\*q \*q" boolean \*q
|
|
When BIOS panel informations aren't available (like on PowerBooks), it
|
|
may still be necessary to use the firmware provided PLL values for the
|
|
panel or flickering will happen. This option will force probing of
|
|
the current value programmed in the chip when X is launched in that
|
|
case. This is only useful for LVDS panels (laptop internal panels).
|
|
The default is
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qTVDACLoadDetect\*q \*q" boolean \*q
|
|
Enable load detection on the TV DAC. The TV DAC is used to drive both
|
|
TV-OUT and analog monitors. Load detection is often unreliable in the
|
|
TV DAC so it is disabled by default.
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qDefaultTMDSPLL\*q \*q" boolean \*q
|
|
Use the default driver provided TMDS PLL values rather than the ones
|
|
provided by the bios. This option has no effect on Mac cards. Enable
|
|
this option if you are having problems with a DVI monitor using the
|
|
internal TMDS controller.
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qDefaultTVDACAdj\*q \*q" boolean \*q
|
|
Use the default driver provided TVDAC Adj values rather than the ones
|
|
provided by the bios. This option has no effect on Mac cards. Enable
|
|
this option if you are having problems with a washed out display on
|
|
the secondary DAC.
|
|
The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qDRI\*q \*q" boolean \*q
|
|
Enable DRI support. This option allows you to enable to disable the DRI.
|
|
The default is
|
|
.B off
|
|
for RN50/ES1000 and
|
|
.B on
|
|
for others.
|
|
.TP
|
|
.BI "Option \*qDefaultConnectorTable\*q \*q" boolean \*q
|
|
Enable this option to skip the BIOS connector table parsing and use the
|
|
driver defaults for each chip.
|
|
The default is
|
|
.B off
|
|
.TP
|
|
.BI "Option \*qMacModel\*q \*q" string \*q
|
|
.br
|
|
Used to specify Mac models for connector tables and quirks. If you have
|
|
a powerbook or mini with DVI that does not work properly, try the alternate
|
|
options as Apple does not seem to provide a good way of knowing whether
|
|
they use internal or external TMDS for DVI. Only valid on PowerPC.
