e956100a60 Fixed possible segfault in win32 gui when switching back from Voodoo to VBE or
Cirrus mode. Set font height to 0 in graphics modes and fixed argument order.

8b96faf99e Some work on the timing code of the Bochs display adapters.
- Voodoo: Use the VGA/Cirrus timers to drive the gui screen update.
  The vertical retrace emulation is still driven by a separate timer.
- VGA/Cirrus: Since we are using the virtual timer, we also have to read
  time_usec() from it.
- vgacore: removed unused timer methods.

ed92dc4dfd Code cleanup: We don't need to copy data here. 2017-04-02 14:01:40 +00:00

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

cbd147fca3 Fixed and improved text mode CO40.
- vgacore: double font and screen width at half dot clock.
- X gui: improved font bitmap generation to support width > 9.
- win32 gui: adjust values to use existing stretching feature.
- guis rfb, sdl, sdl2, vncsrv and wx: double pixels if font width > 9.

524ba46c3d Added the capability to select the operation mode of the VGA update timer.
The realtime mode is enabled by default (patch by Dawn Teschendorf).

59f5a03af6 Rewrite of the virtual timer code to support both modes at the same timer.
The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.

f3a6fbd235 Simplified setup of special runtime menus / dialogs
- If the runtime flag of a bx_list_c object is set, all it's items are set up
  as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
  each single parameter is no longer needed.

4eae421272 Graphics snapshot feature re-implemented for the new graphics API
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
  Voodoo adapter possible

bdf28d89dd Graphics snapshot handling for standard VGA and compatible modes (old graphics
API) moved to the gui code. Splitted graphics_tile_update() in a common and a
specific part. The common part handles the snapshot case if active. As a side
effect, the snapshot feature now works for CGA modes, too. Fixed palette colors
in 8 bpp snapshots.

1fd6745aea Started rewrite of the gui code to make the graphics snapshot independent from
the display adapter code. When ready, the common gui code should handle it
completely. The snapshot handler should set a flag 'snapshot_mode' and then it
should force a display update. The graphics update code should be redirected to
some code that 'draws' to a snapshot buffer. These first steps are done:

- store some guest display settings in the gui code (text / graphics switch,
  x / y resolution and bpp)
- split 8 bpp palette update code in a common and a specific part and store the
  palette values in the gui code
