The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.
In order to enale statitics collection in Bochs CPU:
- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line
the init code. Started with the SeeReg[] array values. Some other setting could
be added later. The parser code is based on the slirp config parser.
Slirp: fixed possible segfault if the value for a parameter is missing.
gui init and string paramter handler. The shortcut keys are now stored in an
array of BX_KEY* values in the gui object.
siminterface.h: Fixed some default return values.
- added new symbol BX_WITH_SDL2 and prepared build system
- TODO #1: add new option --with-sdl2 to configure script
- TODO #2: add new file sdl2.cc (porting seems hard to do - writing from scratch
might be better)
- don't try to resize the simulation window if minimized (iconic)
- handle window size correction in the gui event handler and by calling
resize_main_window(FALSE), since fullscreen mode is not always required
- fixed screen flickering after entering fullscreen for the second time
- now using resize_main_window() directly for leaving fullscreen mode
- dimension_update() now only used for guest display mode change
- TODO: more testing to find cases that can make Bochs crash
- moved fullscreen mode enable/disable stuff to a new function
- now only use dimension_update() for leaving fullscreen mode
- fixed fullscreen issues in text mode
- TODO: check if guest display is too large and add a proper handling for this case
- changing from window mode to fullscreen and back now looks okay
- changing guest resolution in fullscreen mode now also works
- TODO #1: rewrite of the window / fullscreen code to avoid using dimension_update()
to toggle the internal mode
- TODO #2: add size checks in dimension_update() to avoid crash. We could panic
at this point or compress screen to desktop size.
- send lost ALT keyup event after closing notification message box
- disable border of simulation window in fullscreen mode
- TODO #1: fix window sizes after leaving fullscreen mode
- TODO #2: add screen size checks to avoid crash
This fixes the floppy malfunction after restore and maybe other issues. The
buggy code failed to clear the DMA controller mask bits and the floppy DMA
requests never arrived at the CPU.
- device prefix size needed update, but now using log function name instead
- don't use overlapping strcpy() (increment pointer and one single strcpy())
- now using get_logfn_id() to simplify code
TODO: fix floppy access failure after restore
- embedding combined manifest makes BOCHS.EXE usable
- list of DLL plugins now depends on the pci and debugger options
- 'make clean' now removes the generated manifest files
- renamed variable for external rules
- documentation update
