- bx_shadow_bool_c: removed unused bitnum feature and changed data type.
- Changed return type of memory handlers to bool.
- Modified virtual timer, PIC and PIT code.
- Changing VGA extension to "voodoo" did not work in the config interface.
Moved plugin loading to the string parameter handler and added plugin
unloading case.
- Unloading "voodoo" VGA plugin resets pluginVgaDevice to stubVga.
- pluginUnregisterDeviceDevmodel() now supports core plugins.
- Some other small plugin related changes.
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).
It creates an array of strings from a string containing a comma separated list
of options. Now using this function for display library options, USB port
options and ROM image options.
- Now using text_update_common() for the new text update API in addition to the
graphical text snapshot feature.
- Drawing to snapshot buffer moved to new method draw_char_common().
- A gui using the new text update API only needs to implement the new method
draw_char(). The method set_font() is optional and it can be used to update
font bitmaps / pixmaps.
- Modified the RFB gui to use the new API. Now the VGA features split screen
and h/v pel panning are supported by the RFB gui. The legacy text_update()
method is now empty but it must be present for compatiblity.
- TODO: Implement new API in some other guis to reduce code duplication.
- Access to VGA registers via Banshee address space is not memory mapped.
- Added BX_ERRORs for unimplemented unaligned access to i/o registers.
- Access to the unimplemented YUV address space now causes BX_ERROR.
- Removed some TODO comments.
- Added support for split screen mode and horizontal pel panning.
- Text mode cursor now correctly visible independent from blink state.
- Workarounds for the existing text_update() API.
set accordingly.
TODO #1: Text mode features split screen and h/v pel panning missing for now.
TODO #2: Show error messages related to dialogs in message boxes.
- New attempt to fix the host-to-screen bitblt issue with monochrome source.
The specs are wrong at this point. The rules for calculating the real source
pitch are still unknown. These hacks should fix most the glitches.
- Added source colorkeying support for host-to-screen blt with pattern.
- Banshee: Added colorkey support for host-to-screen blts without pattern.
- Clearing base address registers in reset is not okay. Maybe we have to
unregister i/o and memory regions here. This affects other devices, too.
- Some other small changes and typo fixes.
- Added support for "byte packed" monochrome source data.
- TODO #1: All modes except 16 bpp color source untested (based on specs).
- TODO #2: byte / word wizzling, other color orders, 24 bpp source dithering.
- Added support for undithered 24 bpp source data.
- Fixed "standard monochrome" mode in case of transparency.
- TODO: byte / word wizzling, other color orders, 24 bpp source dithering.
- Implemented screen-to-screen blt function (untested).
- Fixed and improved "Rectangle fill" function.
- "SGRAM fill" function rewritten similar to the other functions.
- TODO: cpu-to-screen function (handle data written to bltData register).
- Implemented destination colorkey support for the remaining functions.
- Some other small changes in the Banshee code.
- TODO: Source colorkey support for host-to-screen blts.
- Fixed SGRAM fill command (y start and size have one more bit - spec is wrong).
- CMDFIFO packet type #5: texture address is a 32 bit register number.
- Setting clut_dirty is required when writing to most of the fbiInit registers.
- Added colorkey support for screen-to-screen pattern blt, rectangle fill and
pattern fill commands.
- Consider colorkeying enabled when branching to normal or pattern blt functions.
- Changed 2D TODO messages to BX_ERROR and some other minor changes.
feature of packet type #5. Added some W2 cases for texture writes, modified
code for linear LFB writes and added BX_ERROR messages for the WN cases. Some
more test cases are needed for a complete implementation.
- Real fix for the Voodoo2 DirectX issue after CLUT pens implementation.
- Banshee hardware cursor now uses the CLUT pens for the background.
- Banshee hardware cursor now uses the same 3D start address as update().
- Set clut_dirty flag when writing to fbiInit registers. This fixes a Voodoo2
issue when using the DirectX driver.
- Report another unimplemented case in the texture code.
video refresh in 16 bpp modes. The Banshee also uses this feature in 16 bpp
desktop mode in addition to 3D modes. The code for the pen calculation comes
from the original Voodoo patch for DOSBox. Since it was unused there, I had
disabled it when porting to Bochs.
- Fixed serious issues in 16 bpp mode of XP guest (clipped y value).
- Added BX_ERROR messages for unsupported features.
- Added / updated comments.
- TODO #1: Background pattern issues in XP guest still remain in all modes.
- TODO #2: Some small issues in Win9x guests caused by monochrome host blts.
- Polygon fill: Check if pixels are within clip window.
- Polygon fill: Added error message for unimplemented pattern ROPs.
- Some cleanups in the code for pattern ROPs with transparency.
