- Added simple clip check method to be called for each destination x / y change.
- Use the new clip check in both host-to-screen methods.
- Some related changes.
- TODO: verify other bitblt methods for clipping correctness.
- Calculate host-to-screen data size for "source stride packing" in color mode
similar to the monochrome mode.
- Set up data swizzle mode for all launch area operations.
- Temporarily draw polygon in normal mode in case the currently unsupported
pattern mode is selected.
- TODO #1: Rewrite of the clipping code at least for host-to-screen functions.
- TODO #2: Drawing polygon with pattern if requested.
monochrome source and "source stride" packing. Now adding the source stride
converted to pixels to the 5-bit srcX value.
TODO #1: color source needs to be handled in a similar way (no test case yet).
TODO #2: clipping needs to be rewritten at least for host-to-screen blts.
- vgacore: method get_crtc_params() now returns selected video clock value.
- banshee: now using selected video clock instead of hardcoded VCLK #3.
- cirrus: added vertical frequency to mode switch BX_INFO.
- Moved setup of default i/o register values to reset().
- Set up strapInfo register bits in init().
- Don't overwrite readonly bits in miscInit1 register.
- Set up subsystem ID in VGABIOS ROM in case it's > 32k (doesn't exist yet).
- Copy subsystem ID from ROM to PCI config registers in reset().
- 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.
- 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.
- 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.
- 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.
- 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.
- 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().
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.
- Fixed start address for the gui screen update in 3D overlay mode.
- Small optimization for drawing transparent monochrome bitmaps.
- In the restore case start the fifo thread in after_restore_state().
- Report unimplemented colorkey feature (test case missing).
- TODO: issues in some Windows guests still not fixed.
- Save/restore additions for 2D desktop mode.
- Fixed pitch in 3D overlay mode for hardware cursor.
- TODO list:
- Minor issues in explorer navigation bar of Win98SE.
- Ugly background pattern under software cursor and XP start menu.
- Segfault after switching to 3D mode at XP Direct3D test (Voodoo3 only).
- Serious display issues in 16 bpp modes of XP guest (Voodoo3 only).
- Don't set up and load pre-defined optional plugins in restore mode.
- Remove the save/restore registration in Voodoo destructors.
- TODO: Fix frozen SDL/SDL2 display after restore.
