5) Configuration
The driver auto-detects all device info included memory size, so
use the following device section in your XF86Config file:
Section "Device"
Identifier "NeoMagic"
EndSection
or let xf86config or XF86Setup do this for you.
But if you have problems with auto-detection, you can specify:
VideoRam - in kilobytes
DacSpeed - in MHz
MemBase - physical address of the linear framebuffer
IOBase - physical address of the memory mapped IO registers
6) Driver Options
"no_linear" - banked framebuffer mode
"no_accel" - software rendering only
"sw_cursor" - software cursor only
"no_mmio" - use I/O space directly
"intern_disp" - enable internal display (default)
"extern_disp" - enable external display
"no_stretch" - disable stretching of lower resolution modes on panel
"lcd_center" - center lower resolution modes on panel
NOTE: Stretching of panel image is on by default for lower panel
resolutions.
Options useful for special lcd mode setting (should not be needed):
"prog_lcd_mode_regs" - set special lcd mode registers (2070 default)
"no_prog_lcd_mode_regs" - don't set lcd mode registers (non-2070 default)
"prog_lcd_mode_stretch" - force lcd mode regs if stretching is enabled
"no_prog_lcd_mode_stretch" - no lcd mode regs if stretching (default)
Option for subnotebooks and other laptops with uncommon size panels:
"override_validate_mode" - disable LCD mode checking
WARNING: Disabling mode checking will allow for invalid modes that
could damage your LCD.
7) Known Limitations
* External monitor support on the NM2070.
* Banked, or no_linear mode on the NM2070.
* Horizontal centering for lower than panel resolution on NM2070.
