mode sets both banks to the same value. Reading VBE bank register always
returns the write aperture setting. This feature is designed for the scrolling
function of the VBE 'write character' support. VBE code should use compatibility
mode for now.
TODO: update VGABIOS to use this feature.
- VBE enable register returns 32k granularity flag if enabled.
- VBE bank register returns 32k granularity flag if VBE_DISPI_GETCAPS is set.
- Defining new DISPI ID not necessary.
- TODO: update VGABIOS to use this feature.
- Limit VBE bank size to 64k as expected.
- Enabling VBE mode now clears the whole video memory for all bpp modes unless
"noclear" bit is set.
- Prepared 32k bank granularity mode required for text output functions. Added
new VBE_DISPI_ID6 to indicate this capability. The default is still 64k.
- Added new files with small changes, output can be viewed with Wireshark.
- FIXME: Windows ports crash with original Win98 guest and USB disk connected.
- TODO: mention new feature in documentation.
- 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().
cannot unload itself, BX_UNREGISTER_DEVICE_DEVMODEL() call will fail. Setting
plugin control flag to 0 like other devices do. When starting simulation, all
unused plugins are removed.
NOTE: The pcidev stuff is unmaintained, functionality not tested.
- Don't include paramtree.h in siminterface.h to get rid of duplicates
in a lot of Makefile dependency lines.
- Regenerated Makefile dependencies in iodev and affected subdirectories.
- FIXME #1: including debug.h causes duplicate entries of config.h and osdep.h.
- FIXME #2: cpudb.h appears in most of the iodev* dependencies, but only needed
by config.cc and the cpu class.
- Moved serial and parallel config parameter list creation to the corresponding
device code.
- Unregister serial and parallel bochsrc options in PLUGIN_FINI mode.
- Moved USB config and runtime parameter list creation to bx_init_usb_options().
- textconfig.cc: Small fixes in the optional plugin control.
- Changed variable type of the plugin_t "type" member from enum to Bit16u.
- Added support for returning device flags with the new mode PLUGIN_FLAGS in
the plugin entry functions. It is currently only used for devices that can
be connected to a PCI slot.
- Code cleanup in core device plugins: checking type no longer necessary.
- The "non-plugin" mode now also uses the "loadtype" member of plugin_t.
TODO: Change PCI slot options to bx_param_enum_c and build the choices list
using the new capabilities of the plugin API.
- Disable port "options" parameter after successful connect. While connected,
a device may install runtime options to control it's behaviour.
- Added enable handlers for the "options" parameter to ensure an attempt to
change the device while connected doesn't enable it.
- Some related code cleanups.
