- ne2k: replaced debugger command 'info ne2k' completely by a new version based
on 'info device' with additional arguments and removed all of the now obsolete
stuff (ne2k device stub, macro for print_info())
- pci: added option 'dump=full' for the debugger command 'info device' to show
the whole PCI config space
- TODO: some other devices could have support for additional options in
debug_dump()
- added new class bx_vgacore_c containing the core of the standard VGA
emulation. This is now the base class for both vga and cirrus.
- created 2 separate plugins 'vga' (for standard VGA and VBE) and 'svga_cirrus'
(Cirrus emulation). The vga extension option is used to select which plugin
should be loaded.
- TODO: move the pcivga code to the VGA/VBE code, add subdirectory for display
adapters, severak improvements and cleanups
- changed argument for the text mode info structure to a pointer
- added attribute controller palette to bx_vga_tminfo_t and removed the
previous implementation
- carbon.cc: attempt to fix the text mode colors (untested)
- x.cc: fixed warnings
- added new method get_vga_pixel() that read the color value from EGA/VGA memory layout (moved from
display update code and now also used for snapshots)
- minor code cleanups
- using the same init() method for all display adapters
- new method protected init_standard_vga() for the shared vga core
- new method init_vga_extension() implements the extended features
- moved loading of vgabios image for the ISA case from main.cc to the vga init code
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.
* 'usb_uhci' bochsrc option replaces 'usb1'
* minor changes in the USB code
* removed old VBE i/o port registration (they were incompatible with USB)
* updated FSF address
- fixed saving user plugin options
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
- don't init / reset Cirrus extension if disabled
- store last active BPP value independent from selected vga extension (fixes possible
panic when switching from a Cirrus 640x480 mode to standard VGA)
#1159639)
- size of text snapshot space increased to 128 kByte (for all memory mappings)
- immediately return after the panic when the number of text lines is too large
to avoid segfault
- changes to the original svga_cirrus patch:
* PCI memory/mmio PnP support, some emulation and compile fixes
* ported write mode 4 + 5 and some bufixes from cirrus vga in qemu
* new graphics API, hardware cursor support, configure option added (Robin Kay)
* partial support for transparent bitblt and bitblt write mask
memory handling in memory.cc removed)
- CRTC write protection implemented
- 16-bit read access to some VGA registers added
- memory handler code now conciders the status of the A20 line
