+
+ viafb_refresh1: (secondary display device)
+ 60, 75, 85, 100, 120 (default:60)
+
+ viafb_active_dev:
+ This option is used to specify active devices.(CRT, DVI, CRT+LCD...)
+ DVI stands for DVI or HDMI, E.g., If you want to enable HDMI,
+ set viafb_active_dev=DVI. In SAMM case, the previous of
+ viafb_active_dev is primary device, and the following is
+ secondary device.
+
+ For example:
+ To enable one device, such as DVI only, we can use:
+ modprobe viafb viafb_active_dev=DVI
+ To enable two devices, such as CRT+DVI:
+ modprobe viafb viafb_active_dev=CRT+DVI;
+
+ For DuoView case, we can use:
+ modprobe viafb viafb_active_dev=CRT+DVI
+ OR
+ modprobe viafb viafb_active_dev=DVI+CRT...
+
+ For SAMM case:
+ If CRT is primary and DVI is secondary, we should use:
+ modprobe viafb viafb_active_dev=CRT+DVI viafb_SAMM_ON=1...
+ If DVI is primary and CRT is secondary, we should use:
+ modprobe viafb viafb_active_dev=DVI+CRT viafb_SAMM_ON=1...
+
+ viafb_display_hardware_layout:
+ This option is used to specify display hardware layout for CX700 chip.
+ 1 : LCD only
+ 2 : DVI only
+ 3 : LCD+DVI (default)
+ 4 : LCD1+LCD2 (internal + internal)
+ 16: LCD1+ExternalLCD2 (internal + external)
+
+ viafb_second_size:
+ This option is used to set second device memory size(MB) in SAMM case.
+ The minimal size is 16.
+
+ viafb_platform_epia_dvi:
+ This option is used to enable DVI on EPIA - M
+ 0 : No DVI on EPIA - M (default)
+ 1 : DVI on EPIA - M
+
+ viafb_bus_width:
+ When using 24 - Bit Bus Width Digital Interface,
+ this option should be set.
+ 12: 12-Bit LVDS or 12-Bit TMDS (default)
+ 24: 24-Bit LVDS or 24-Bit TMDS
+
+ viafb_device_lcd_dualedge:
+ When using Dual Edge Panel, this option should be set.
+ 0 : No Dual Edge Panel (default)
+ 1 : Dual Edge Panel
+
+ viafb_video_dev:
+ This option is used to specify video output devices(CRT, DVI, LCD) for
+ duoview case.
+ For example:
+ To output video on DVI, we should use:
+ modprobe viafb viafb_video_dev=DVI...
+
+ viafb_lcd_port:
+ This option is used to specify LCD output port,
+ available values are "DVP0" "DVP1" "DFP_HIGHLOW" "DFP_HIGH" "DFP_LOW".
+ for external LCD + external DVI on CX700(External LCD is on DVP0),
+ we should use:
+ modprobe viafb viafb_lcd_port=DVP0...
+
+Notes:
+ 1. CRT may not display properly for DuoView CRT & DVI display at
+ the "640x480" PAL mode with DVI overscan enabled.
+ 2. SAMM stands for single adapter multi monitors. It is different from
+ multi-head since SAMM support multi monitor at driver layers, thus fbcon
+ layer doesn't even know about it; SAMM's second screen doesn't have a
+ device node file, thus a user mode application can't access it directly.
+ When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and
+ viafb_bpp1, viafb_refresh and viafb_refresh1 can be different.
+ 3. When console is depending on viafbinfo1, dynamically change resolution
+ and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE
+ instead of calling common ioctl function FBIOPUT_VSCREENINFO since
+ viafb doesn't support multi-head well, or it will cause screen crush.
+ 4. VX800 2D accelerator hasn't been supported in this driver yet. When
+ using driver on VX800, the driver will disable the acceleration funciton.
+ as default.
+
+
+[Configure viafb with "fbset" tool]
+-----------------------------------
+ "fbset" is an inbox utility of Linux.
+ 1. Inquire current viafb information, type,
+ # fbset -i
+
+ 2. Set various resolutions and viafb_refresh rates,
+ # fbset <resolution-vertical_sync>
+
+ example,
+ # fbset "1024x768-75"
+ or
+ # fbset -g 1024 768 1024 768 32
+ Check the file "/etc/fb.modes" to find display modes available.
+
+ 3. Set the color depth,
+ # fbset -depth <value>
+
+ example,
+ # fbset -depth 16
+
+[Bootup with viafb]:
+--------------------
+ Add the following line to your grub.conf:
+ append = "video=viafb:viafb_mode=1024x768,viafb_bpp=32,viafb_refresh=85"
+
