AMX support (#212) 2024-01-10 20:13:25 +02:00
Volker Ruppert
cfa7276cb9 Added support for driving the VGA display update timer with VSYNC. 
- Using the special value of 0 enables this feature. In that case the vertical
  frequency is used for the display updates. The update() method is called at
  the "vertical retrace end" time and sets the time of the display start. This
  value is used to set the vertical retrace indicator in VGA register 0x03da.
- This feature is not yet enabled if Voodoo support is present. The Voodoo device
  has it's own vertical timer and needs some more testing and possibly some changes.
