- Added support for stippled lines.
- Fixed return values of the I2C interface with no VMI/decoder connected.
- Added some comments about current status of the Banshee code.
take RAW_BYTES string out of bx_param_string_c into new param type bx_param_bytestring_c (better name, anybody?)
this is intermediate step, later it would be better to merge bx_param_string into generic template bx_param<type>
but bx_param_bytestring_cis not matching that concept (or probably will continue to inherit from bx_param<string>)
- Basic I2C implementation for DDC2B support.
- Added VESA EDID structure (values from a patch for the LGPL'd VGABIOS).
- Windows now detecting plug&play monitor "Bochs Screen" if an original VGABIOS
image is used (Cirrus PCI / Voodoo Banshee).
- TODO: Add this feature in the Cirrus version of the LGPL'd VGABIOS.
use new method do dump param tree during save/restore, GUI and text debugger and other places
significantly reduce code duplication over multiple modules
the method dumps param to the FILE
use new method do dump param tree during save/restore
also make more use of parse_param methods which initialize param from a string
- Happy new year!
- Improved pixel format conversion in host-to-screen operations.
- Rewrite of the linear framebuffer read/write code fixes icons in 16 bpp mode.
- Don't flood log file when polling the 2D status register (similar to 3D one).
- FIXME list:
- Minor issues in all Banshee modes (e.g. forward/back buttons in explorer).
- Display errors in 16 bpp mode after leaving 3D mode.
- Display errors in 16 bpp mode in case debug messages are turned on (timing).
- Voodoo2 3D demo "donut" still fails.
- Bochs crashes on Windows host (MSVC in some cases, MSYS2 64-bit build also
reported, but not yet reproduced.
- TODO list:
- Remaining 2D stuff: polygon fill, stretching functions.
- Move Banshee stuff to separate files.
- Add Voodoo3 support (it's an improved Banshee card).
- Simplified register writes from CMDFIFO using new methods in the new classes.
- Started work on reset() and continued work on save/restore support.
- Mention the Banshee model in the Bochs documentation.
bx_voodoo_base_c that contains the shared code and the new classes
bx_voodoo_1_2_c and bx_banshee_c with the specific implementations. There are
not functional changes yet. TODO: The Banshee specific stuff could be moved to
separate files, but should still remain in the same plugin as Voodoo 1/2.
- Fixed alignment for unpacked monochrome source data in case the calculated
required amount of data for one row is more than the given source pitch.
In even rows the leftmost pixel comes from the LSB bit #7 as expected.
In odd rows the whole row is aligned to the next dword boundary (the rightmost
pixel comes from the MSB bit #0). This alternating alignment is not documented,
but fixes some bitmaps (e.g. Win95 login / logout dialogs).
- Fixed calculation of host-to-screen data size for the pixel alignment > 0 and
color depth > 8.
- Added minimal support for pixel format conversion (32/24 to 16).
- Also set the "Banshee busy" flag if one of the CMDFIFOs is busy.
- Fixed CMDFIFO error message condition.
- Tiled source pitch is only used for screen-to-screen operations.
- Use the CMDFIFO wakeup on vertical retrace only for the 3D mode.
- Report screen mode change (2D, 3D, mixed).
- Added BX_ERRORs for currently unsupported pixel format conversion.
- Only continue bitblt operation if width and height is > 0 after clipping.
- Temporary hack: Processing CMDFIFO packets directly after completion fixes
some display issues (FIXME: 3D mode should work like Voodoo2).
