- 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)
* changed all %ll format descriptions to FMT_LL macro so that
Microsoft Visual C works correctly (it uses %I64)
* missing type conversions added
* cdrom.cc: variable types for win32 fixed
* removed some unused variables in eth_win32.cc and harddrv.cc
* added missing includes in make_cmos_image.c and niclist.c
* support for different resource compilers added (rc / windres)
* bochs must be linked with advapi.lib for registry access
* optimization flag changed to /Ox
* symbols BX_HAVE_MKSTEMP, BX_HAVE_SYS_MMAN_H and HAVE_ETHERTAP must be set to 0
* BX_HAVE_REALTIME_USEC definition fixed for MSVC
* vmware3.h: definition of COW_Header fixed for MSVC
- maximum number of text lines changed to 100 (CGA "graphics" mode 160x100)
- size of text snapshot buffer changed to 32k (size of MDA/CGA text memory)
- removed obsolete macro CGA_TEXT_ADDR()
in text mode. The new variables 'text_rows' and 'text_cols' are used in the
text_update() function.
- desriptions of the functions text_update() and dimension_update() updated
