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.
- fixed clock values (assigned to wrong model)
- LFB read/write: don't limit y values to 1023 (4MB now usable this way)
- additional Voodoo2 fbiInit* register writes now handled like the Voodoo1 ones
- destructor: free memory only when initialized
- parameter 'enabled' must be initialized with 1 (TODO: fix other plugins)
- PCI register fixes (Voodoo2 now detected, but not usable)
- fixed pluginlog init in non-plugin mode
- reduced logprefix length limit and use it for the related string parameter
- increase the device prefix size to 6
- TODO: change some more device prefixes
- renamed trigger_timer() methods to refresh_display()
- new argument 'redraw' added to force a refresh of the entire screen
(used in snapshot mode)
- siminterface method refresh_vga() now checks if the Bochs gui init is complete
- use SIM->refresh_vga() in some more cases
- 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
- don't enable Voodoo mode if hSync or vSync are still 0 to avoid Bochs crash
(division by zero error)
- handle PCI register 0x40 (initEnable)
- fixed reported display size
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
