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
37 Cougar3DR SM731
39 MSOC SM501,SM502

43 Please refer to xorg.conf(5) for general configuration details. This
44 section only covers configuration details specific to this driver. All
45 options names are case and white space insensitive when parsed by the
46 server, for example, "lynxe" and "LynxE" are equivalent.
47 Multihead mode configuration is done through the RandR1.2 interface
49 (see xorg.conf(5) and xrandr(1) for further information). Hardware
50 accelerated screen rotation and framebuffer resizing are only supported
51 with the EXA acceleration architecture (see the AccelMethod option
52 below).
53 The driver auto-detects the chipset type, but the following ChipSet
55 names may optionally be specified in the config file "Device" section,
56 and will override the auto-detection:
57 "lynx", "lynxe", "lynx3d", "lynxem", "lynxem+", "lynx3dm",
59 "cougar3dr", "msoc".
60 The following Cursor Options are supported:
63 Option "HWCursor" "boolean"
65 Enable or disable the HW cursor. Default: on.
66 Option "SWCursor" "boolean"
68 Inverse of "HWCursor". Default: off.
69 The following display Options are supported:
72 Option "VideoKey" "integer"
74 Set the video color key. Default: a little off full blue.
75 Option "ByteSwap" "boolean"
77 Turn on byte swapping for capturing using SMI demo board.
78 Default: off.
79 Option "Interlaced" "boolean"
81 Turn on interlaced video capturing. Default: off.
82 Option "UseBIOS" "boolean"
84 Use the BIOS to set the modes. This is used for custom panel
85 timings. Default: off for SM72x and SM5xx, otherwise on.
86 Option "Dualhead" "boolean"
88 Enable dualhead mode. Currently not all chips are supported and
89 hardware video overlay (XV) support may have some limitations.
90 Default: off.
91 Option "PanelSize" "widthxheight"
93 Override LCD panel dimension autodetection.
94 Option "UseFBDev" "boolean"
96 Don't actually program the hardware mode registers, but leave it
97 as set by the operating system. Only available on MSOC chips.
98 Default: off.
99 Option "CSCVideo" "boolean"
101 CSC video uses color space conversion to render video directly
102 to the framebuffer, without using an overlay. Only available on
103 MSOC chips. Default: on.
104 The following video memory Options are supported:
106 Option "mclk" "integer"
108 Sets the memory clock. You must specify the units. For example
109 50Mhz is the same as 50000Khz or 50000000Hz. On MSOC chips this
110 is the main clock source for all functional blocks, such as the
111 2D engine, GPIO, Video Engine, and DMA Engine. This option is
112 only used for debugging purposes on MSOC chips. Default: probe
113 the memory clock value, and use it at server start.
114 Option "mxclk" "integer"
116 Sets the memory clock. You must specify the units. For example
117 50Mhz is the same as 50000Khz or 50000000Hz. Clock source for
118 the local SDRAM controller. This option is only available on
119 MSOC chips and used only for debugging purposes. Default: probe
120 the memory clock value, and use it at server start.
121 The following acceleration and graphics engine Options are supported:
123 Option "NoAccel"
125 Disable acceleration. Very useful for determining if the driver
126 has problems with drawing and acceleration routines. This is
127 the first option to try if your server runs but you see graphic
128 corruption on the screen. Using it decreases performance, as it
129 uses software emulation for drawing operations the video driver
130 can accelerate with hardware. Default: acceleration is enabled.
131 Option "AccelMethod" "string"
133 Chooses between available acceleration architectures. Valid
134 options are XAA and EXA. XAA is the traditional acceleration
135 architecture and support for it is very stable. EXA is a newer
136 acceleration architecture with better performance for the Render
137 and Composite extensions, but the rendering code for it is newer
138 and possibly unstable. The default is XAA.
139 The following PCI bus Options are supported:
142 Option "PciBurst" "boolean"
144 will enable PCI burst mode. This should work on all but a few
145 broken PCI chipsets, and will increase performance. Default:
146 on.
147 Option "PciRetry" "boolean"
149 will allow the driver to rely on PCI Retry to program the regis‐
150 ters. PciBurst must be enabled for this to work. This will
151 increase performance, especially for small fills/blits, because
152 the driver does not have to poll the card before sending it com‐
153 mands to make sure it is ready. It should work on most recent
154 PCI chipsets. Default: value of PciBurst option.

162 For assistance with this driver, or Xorg in general, check the web site
163 at http://www.x.org/. If you find a problem with Xorg or have a ques‐
164 tion not answered in the FAQ please use our bug report form available
165 on the web site or send mail to xorg@lists.freedesktop.org. When
166 reporting problems with the driver send as much detail as possible,
167 including chipset type, a server output log, and operating system
168 specifics.
