.SH DESCRIPTION
|
||
|
|
.B siliconmotion
|
||
|
|
is an XFree86 driver for Silicon Motion based video cards. The driver is fully
|
||
|
|
accelerated, and provides support for the following framebuffer depths:
|
||
|
|
8, 16, and 24. All
|
||
|
|
visual types are supported for depth 8, and TrueColor
|
||
|
|
visuals are supported for the other depths.
|
||
|

.SH CONFIGURATION DETAILS
|
||
|
|
Please refer to XF86Config(__filemansuffix__) for general configuration
|
||
|
|
details. This section only covers configuration details specific to this
|
||
|
|
driver. All options names are case and white space insensitive when
|
||
|
|
parsed by the server, for example, "lynxe" and "LynxE" are equivalent.
|
||
|
|
.PP
|
||
|
|
The driver auto-detects the chipset type, but the following
|
||
|
|
.B ChipSet
|
||
|
|
names may optionally be specified in the config file
|
||
|
|
.B \*qDevice\*q
|
||
|
|
section, and will override the auto-detection:
|
||
|
|
.PP
|
||
|
|
.RS 4
|
||
|
|
"lynx", "lynxe", "lynx3d", "lynxem", "lynxem+", "lynx3dm".
|
||
|
|
.RE
|
||
|
|
|
||

|
||
|
|
.BI "Option \*qHWCursor\*q \*q" boolean \*q
|
||
|
|
Enable or disable the HW cursor. Default: on.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qSWCursor\*q \*q" boolean \*q
|
||
|
|
Inverse of "HWCursor". Default: off.
|
||
|
|
|
||
|
|
.PP
|
||
|
|
The following display
|
||
|
|
.B Options
|
||
|
|
are supported:
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qShadowFB\*q \*q" boolean \*q
|
||
|
|
Use shadow framebuffer. Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qRotate\*q \*qCW\*q"
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qRotate\*q \*qCCW\*q"
|
||
|
|
Rotate the screen CW - clockwise or CCW - counter clockwise.
|
||
|
|
Uses ShadowFB. Default: no rotation.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qVideoKey\*q \*q" integer \*q
|
||
|
|
Set the video color key. Default: a little off full blue.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qByteSwap\*q \*q" boolean \*q
|
||
|
|
Turn on byte swapping for capturing using SMI demo board. Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qInterlaced\*q \*q" boolean \*q
|
||
|
|
Turn on interlaced video capturing. Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qUseBIOS\*q \*q" boolean \*q
|
||
|
|
Use the BIOS to set the modes. This is used for custom panel timings.
|
||
|
|
Default: on.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qZoomOnLCD\*q \*q" boolean \*q
|
||
|

Allow changing resolution on LCD (Ctrl-Alt-Plus and Ctrl-Alt-Minus).
|
||
|
|
Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qDualhead\*q \*q" boolean \*q
|
||
|
|
Enable dualhead mode. Due to hardware limitations, dualhead is limited
|
||
|
|
to depth 16 and to the panel size and timings on both the flat panel and
|
||
|
|
the CRT and the CRT must be to the right of the flat panel. Only lynx
|
||
|
|
chips are supported at the moment.
|
||
|
|
Default: off.
|
||
|
|
|
||
|
|
.PP
|
||
|
|
The following video memory
|
||
|
|
.B Options
|
||
|
|
are supported:
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qset_mclk\*q \*q" integer \*q
|
||
|
|
sets the memory clock, where
|
||
|
|
.I integer
|
||
|
|
is in kHz, and
|
||
|
|
.I integer
|
||
|
|
<= 100000. Default: probe the memory clock value,
|
||
|
|
and use it at server start.
|
||
|
|
|
||
|
|
|
||
|
|
.PP
|
||
|
|
The following acceleration and graphics engine
|
||
|
|
.B Options
|
||
|
|
are supported:
|
||
|
|
.TP
|
||
|
|
.B "Option \*qNoAccel\*q"
|
||
|
|
Disable acceleration. Very useful for determining if the
|
||
|
|
driver has problems with drawing and acceleration routines. This is the first
|
||
|
|
option to try if your server runs but you see graphic corruption on the screen.
|
||
|
|
Using it decreases performance, as it uses software emulation for drawing
|
||
|
|
operations the video driver can accelerate with hardware.
|
||
|
|
Default: acceleration is enabled.
|
||
|
|
.TP
|
||
|
|
.B "Option \*qfifo_aggressive\*q"
|
||
|
|
.TP
|
||
|
|
.B "Option \*qfifo_moderate\*q"
|
||
|
|
.TP
|
||
|
|
.B "Option \*qfifo_conservative\*q"
|
||
|
|
alter the settings
|
||
|
|
for the threshold at which the pixel FIFO takes over the internal
|
||
|
|
memory bus to refill itself. The smaller this threshold, the better
|
||
|
|
the acceleration performance of the card. You may try the fastest
|
||
|
|
setting
|
||
|
|
.RB ( "fifo_aggressive" )
|
||
|
|
and move down if you encounter pixel corruption.
|
||
|
|
The optimal setting will probably depend on dot-clock and on color
|
||
|
|
depth. Note that specifying any of these options will also alter other
|
||
|
|
memory settings which may increase performance, so trying
|
||
|
|
.B "fifo_conservative"
|
||
|
|
will in most cases be a slight benefit (this uses the chip defaults).
|
||
|
|
If pixel corruption or transient streaking is observed during drawing
|
||
|
|
operations then removing any fifo options is recommended. Default: none.
|
||
|
|
|
||
|
|
.PP
|
||
|
|
The following PCI bus
|
||
|
|
.B Options
|
||
|
|
are supported:
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qpci_burst\*q \*q" boolean \*q
|
||
|
|
will enable PCI burst mode. This should work on all but a
|
||
|
|
few broken PCI chipsets, and will increase performance. Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qpci_retry\*q \*q" boolean \*q
|
||
|
|
will allow the driver to rely on PCI Retry to program the
|
||
|
|
ViRGE registers.
|
||
|
|
.B "pci_burst"
|
||
|
|
must be enabled for this to work.
|
||
|
|
This will increase performance, especially for small fills/blits,
|
||
|
|
because the driver does not have to poll the ViRGE before sending it
|
||
|
|
commands to make sure it is ready. It should work on most
|
||
|
|
recent PCI chipsets. 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.
