Using a temporary subsystem ID, since I haven't found a VGABIOS ROM image for
the PCI version and Bochs doesn't support AGP yet. After modifying Voodoo3.inf
the driver could be installed successfully in Win95/98 and the Voodoo3 works as
expected (same issues as the Banshee model).
Removed BX_ERROR message about setting undocumented srcXY register bits. They
seem to have no effect on the emulation and could be ignored.
- Screen-to-screen blt: added support for expanding monochrome source data.
- Fixed calculation of the pitch for packed source data.
- Fixed repeated execution of some commands in non-immediate mode.
- PCI devices: fixed and improved BX_INFO / BX_DEBUG messages.
- Added INT pin init to method init_pci_conf().
- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.
- Added new structure bx_pci_bar_t that contains all parameters related to the
PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
BARs and the ROM BAR. Writes to other registers are forwarded to the device
specific PCI write handlers. Removed BAR and ROM BAR handling from the
specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.
- 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.
