17 siliconmotion is an Xorg driver for Silicon Motion based video cards.
18 The driver is fully accelerated, and provides support for the following
19 framebuffer depths: 8, 16, and 24. All visual types are supported for
20 depth 8, and TrueColor visuals are supported for the other depths.
21
23 The siliconmotion driver supports PCI and AGP video cards based on the
24 following Silicon Motion chips:
25 Lynx SM910
27 LynxE SM810
29 Lynx3D SM820
31 LynxEM SM710
33 LynxEM+ SM712
35 Lynx3DM SM720

39 Please refer to xorg.conf(5) for general configuration details. This
40 section only covers configuration details specific to this driver. All
41 options names are case and white space insensitive when parsed by the
42 server, for example, "lynxe" and "LynxE" are equivalent.
43 The driver auto-detects the chipset type, but the following ChipSet
45 names may optionally be specified in the config file "Device" section,
46 and will override the auto-detection:
47 "lynx", "lynxe", "lynx3d", "lynxem", "lynxem+", "lynx3dm".
49 The following Cursor Options are supported:
52 Option "HWCursor" "boolean"
54 Enable or disable the HW cursor. Default: on.
55 Option "SWCursor" "boolean"
57 Inverse of "HWCursor". Default: off.
58 The following display Options are supported:
61 Option "ShadowFB" "boolean"
63 Use shadow framebuffer. Default: off.
64 Option "Rotate" "CW"
66 Option "Rotate" "CCW"
68 Rotate the screen CW - clockwise or CCW - counter clockwise.
69 Uses ShadowFB. Default: no rotation.
70 Option "VideoKey" "integer"
72 Set the video color key. Default: a little off full blue.
73 Option "ByteSwap" "boolean"
75 Turn on byte swapping for capturing using SMI demo board.
76 Default: off.
77 Option "Interlaced" "boolean"
79 Turn on interlaced video capturing. Default: off.
80 Option "UseBIOS" "boolean"
82 Use the BIOS to set the modes. This is used for custom panel
83 timings. Default: on.
84 Option "ZoomOnLCD" "boolean"
86 Allow changing resolution on LCD (Ctrl-Alt-Plus and Ctrl-Alt-
87 Minus). Default: off.
88 Option "Dualhead" "boolean"
90 Enable dualhead mode. Due to hardware limitations, dualhead is
91 limited to depth 16 and to the panel size and timings on both
92 the flat panel and the CRT and the CRT must be to the right of
93 the flat panel. Only lynx chips are supported at the moment.
94 Default: off.
95 The following video memory Options are supported:
98 Option "set_mclk" "integer"
100 sets the memory clock, where integer is in kHz, and integer <=
101 100000. Default: probe the memory clock value, and use it at
102 server start.
103 The following acceleration and graphics engine Options are supported:
107 Option "NoAccel"
109 Disable acceleration. Very useful for determining if the driver
110 has problems with drawing and acceleration routines. This is
111 the first option to try if your server runs but you see graphic
112 corruption on the screen. Using it decreases performance, as it
113 uses software emulation for drawing operations the video driver
114 can accelerate with hardware. Default: acceleration is enabled.
115 Option "fifo_aggressive"
117 Option "fifo_moderate"
119 Option "fifo_conservative"
121 alter the settings for the threshold at which the pixel FIFO
122 takes over the internal memory bus to refill itself. The smaller
123 this threshold, the better the acceleration performance of the
124 card. You may try the fastest setting (fifo_aggressive) and move
125 down if you encounter pixel corruption. The optimal setting
126 will probably depend on dot-clock and on color depth. Note that
127 specifying any of these options will also alter other memory
128 settings which may increase performance, so trying fifo_conser‐
129 vative will in most cases be a slight benefit (this uses the
130 chip defaults). If pixel corruption or transient streaking is
131 observed during drawing operations then removing any fifo
132 options is recommended. Default: none.
133 The following PCI bus Options are supported:
136 Option "pci_burst" "boolean"
138 will enable PCI burst mode. This should work on all but a few
139 broken PCI chipsets, and will increase performance. Default:
140 off.
141 Option "pci_retry" "boolean"
143 will allow the driver to rely on PCI Retry to program the ViRGE
144 registers. pci_burst must be enabled for this to work. This
145 will increase performance, especially for small fills/blits,
146 because the driver does not have to poll the ViRGE before send‐
147 ing it commands to make sure it is ready. It should work on most
148 recent PCI chipsets. Default: off.
149 Option "AccelMethod" "string"
151 Chooses between available acceleration architectures. Valid
152 options are XAA and EXA. XAA is the traditional acceleration
153 architecture and support for it is very stable. EXA is a newer
154 acceleration architecture with better performance for the Render
155 and Composite extensions, but the rendering code for it is newer
156 and possibly unstable. The default is XAA.
157 The following additional Options are supported:
160 Option "ShowCache" "boolean"
162 Enable or disable viewing offscreen cache memory. A development
163 debug option. Default: off.

172 at http://www.x.org/. If you find a problem with Xorg or have a ques‐
173 tion not answered in the FAQ please use our bug report form available
174 on the web site or send mail to xorg@lists.freedesktop.org. When
175 reporting problems with the driver send as much detail as possible,
176 including chipset type, a server output log, and operating system
177 specifics.
