- calculation of the VBE virtual height for >8bpp fixed
- visible screen size must be recalculated after changing the virtual width
- modify standard VGA register when enabling a VBE mode (some test applications
expect this behaviour)
- BX_INFO messages in the VBE code fixed
DEV_kbd_gen_scancode() is called instead of DEV_kbd_put_scancode(). This
change enables the support for different scancode sets. The win32 scancodes
are now converted to BX_KEY_* values (partially copied from gui/win32.cc)
- new text mode features: line offset, cursor size, font height
- key handling rewritten (taken from x.cc)
- headerbar now working
- headerbar colors changed
- graphics modes > 640x480 now cause a BX_PANIC
* configure.in: readline check is only necessary if the debugger is enabled
(patch from Jeroen Janssen)
* iodev/Makefile.in: dependencies updated after adding gameport device
- don't clear the VBE memory if the new flag VBE_DISPI_NOCLEARMEM is set
- vbe_bpp_multiplier for the 4bpp mode set to 1 (usually unused, but this value is save)
(based on a patch from Christopher Nelson <paradox@BBHC.ORG>)
* the win32 gui changes the bitmap settings using the bpp argument
* added stubs for all guis except win32
* descriptions of function dimension_update() updated
font usage)
- horizontal and vertical pel panning in text mode implemented (without windows
fonts only)
- separate bitmap for the textmode cursor no longer necessary
- text_update(): unused variable new_start removed
compile time. The old version used this fonts for char heights smaller 14.
If the Windows fonts are enabled, the font heights 12, 14 and 16 are used.
These features are not available in that case:
* charmap change
* char width switch 8/9
* horizontal and vertical pel panning
If the Windows fonts are disabled, the changeable guest font is used and all
implemented features are available. This is the default setting.
TODO: implement horizontal and vertical pel panning
FIXME: Should we add a bochsrc option to control the font usage?
- invalidate character at previous and new cursor location before entering the
update loop
- cursor drawing moved into the update loop
- variables for previous cursor position renamed
- invalidate character at previous and new cursor location before entering the
update loop
- cursor drawing moved into the update loop
- speed optimizations in function DrawBochsBitmap() (malloc/free removed)
- description of function text_update() updated
(using 72 Hz vertical frequency). The vertial retrace phase is often used for
vga register or memory manipulations to reduce screen flickering.
- update(): check variable vga_mem_updated before everything else
running on a 32 bit host. The problem was that the FPU code uses native pointers to
represent addresses. The assumption that an emulated address is the same size as a
native pointer breaks down when emulating 64 bit addresses on a 32 bit host. The
patch replaces the occurrences of such an address with a bx_address type.
Once this patch has been reviewed by other developers, it will be committed to the
main cvs branch.
(without localized variables)
- start address support for CGA modes added
- start address support for mode 13h completed
- clearing the text snapshot is not necessary after a start address change
(set needs_update to 1 in graphics mode only)
