104
105 viafb_active_dev:
106 This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
107 DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
108 set viafb_active_dev=DVI. In SAMM case, the previous of
109 viafb_active_dev is primary device, and the following is
110 secondary device.
111
112 For example:
113 To enable one device, such as DVI only, we can use:
114 modprobe viafb viafb_active_dev=DVI
115 To enable two devices, such as CRT+DVI:
116 modprobe viafb viafb_active_dev=CRT+DVI;
117
118 For DuoView case, we can use:
119 modprobe viafb viafb_active_dev=CRT+DVI
120 OR
121 modprobe viafb viafb_active_dev=DVI+CRT...
122
123 For SAMM case:
124 If CRT is primary and DVI is secondary, we should use:
125 modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
126 If DVI is primary and CRT is secondary, we should use:
127 modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
128
129 viafb_display_hardware_layout:
130 This option is used to specify display hardware layout for CX700 chip.
131 1 : LCD only
132 2 : DVI only
133 3 : LCD+DVI (default)
134 4 : LCD1+LCD2 (internal + internal)
135 16: LCD1+ExternalLCD2 (internal + external)
136
137 viafb_second_size:
138 This option is used to set second device memory size(MB) in SAMM case.
139 The minimal size is 16.
140
141 viafb_platform_epia_dvi:
142 This option is used to enable DVI on EPIA - M
143 0 : No DVI on EPIA - M (default)
144 1 : DVI on EPIA - M
145
146 viafb_bus_width:
147 When using 24 - Bit Bus Width Digital Interface,
148 this option should be set.
149 12: 12-Bit LVDS or 12-Bit TMDS (default)
150 24: 24-Bit LVDS or 24-Bit TMDS
151
152 viafb_device_lcd_dualedge:
153 When using Dual Edge Panel, this option should be set.
154 0 : No Dual Edge Panel (default)
155 1 : Dual Edge Panel
156
157 viafb_video_dev:
158 This option is used to specify video output devices(CRT, DVI, LCD) for
159 duoview case.
160 For example:
161 To output video on DVI, we should use:
162 modprobe viafb viafb_video_dev=DVI...
163
164 viafb_lcd_port:
165 This option is used to specify LCD output port,
166 available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
167 for external LCD + external DVI on CX700(External LCD is on DVP0),
168 we should use:
169 modprobe viafb viafb_lcd_port=DVP0...
170
171Notes:
172 1. CRT may not display properly for DuoView CRT & DVI display at
173 the "640x480" PAL mode with DVI overscan enabled.
174 2. SAMM stands for single adapter multi monitors. It is different from
175 multi-head since SAMM support multi monitor at driver layers, thus fbcon
176 layer doesn't even know about it; SAMM's second screen doesn't have a
177 device node file, thus a user mode application can't access it directly.
178 When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
179 viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
180 3. When console is depending on viafbinfo1, dynamically change resolution
181 and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
182 instead of calling common ioctl function FBIOPUT_VSCREENINFO since
183 viafb doesn't support multi-head well, or it will cause screen crush.
184 4. VX800 2D accelerator hasn't been supported in this driver yet. When
185 using driver on VX800, the driver will disable the acceleration
186 function as default.
187
188
189[Configure viafb with "fbset" tool]
190-----------------------------------
191 "fbset" is an inbox utility of Linux.
192 1. Inquire current viafb information, type,
193 # fbset -i
194
195 2. Set various resolutions and viafb_refresh rates,
196 # fbset <resolution-vertical_sync>
197
198 example,
199 # fbset "1024x768-75"
200 or
201 # fbset -g 1024 768 1024 768 32
202 Check the file "/etc/fb.modes" to find display modes available.
203
204 3. Set the color depth,
205 # fbset -depth <value>
206
207 example,
208 # fbset -depth 16
209
210[Bootup with viafb]:
211--------------------
212 Add the following line to your grub.conf:
213 append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
