6dba96d10a Some changes related to the PCI ROM handling.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
  the PCI ROM case only (could be extended).

19b98b1145 Simplified code for the "optromimage" and "optramimage" options stuff (saving
configuration, loading images). Cleaned up "romimage" option parsing and
prepared parameter "options" for the behaviour of the Bochs BIOS.
TODO: implement BIOS option "fastboot" to skip the boot menu prompt.

7a34f00f99 extracted fetchdecode into separated folder under cpu and also out of BX_CPU_C class into stand-alone module. Next step: wrap it up nicely and define clear interace to CPU model to minimize dependencies. Ideally I need fetchdecode to not include CPU at all 2016-06-12 21:23:48 +00:00

58019a1649 Renamed "ltdl.h" to "ltdl-bochs.h" to avoid conflicts with the include file
that is a part of the libtool package. Updated Makefile dependencies.
TODO: check if we can get rid of the ltdl*.* files (this would be possible if
the ltdl library is always available if libtool is present).

cc56245407 started implementing the i430FX chipset
- renamed config parameter "i440fx_support" to "enabled"
- new config parameter "chipset" added (current choices "i430FX" and "i440FX")
- don't load ACPI support if the i430FX chipset is selected
- select register values for the core PCI devices depending on the chipset
- USB UHCI must be connected to a PCI slot if the i430FX chipset is used
- rombios changes to make the i430FX chipset work
- TODO #1: implement limitation to 1 cpu and 128 MB RAM for the i430FX chipset
- TODO #2: verify register behaviour of both chipsets

ed669adfd1 - rewrite of the PCI memory management code for the expansion ROM and BIOS area
- store memory type array in the memory object to avoid calling the pci plugin
    frequently. The pci code calls a memory method to change the memory type in
    case the PAM registers are modified.
  - removed now obsolete code and minor cleanups

1f18f5831f - final fix for busmaster DMA transfers from device to memory: new memory method
writePhysicalBlock() replaces the buggy code in iodev.h.
  Calling pageWriteStampTable.decWriteStamp(addr) is required here to make memcpy() work.

d11114ac19 Patch for emulating target with larger memory than host has available by Gary Cameron.
The patch was posted in mailing list at Thu 6/16/2011.

Desription for CHANGES:

- Memory
  - Added new configure option which enables RAM file backing for large guest
    memory with a smaller amount host memory, without causing a panic when
    host memory is exhausted (patch by Gary Cameron). To enable configure with
        --enable-large-ramfile option.

f57b14d338 Extended the interface of the fetch handler to general direct memory access handler.
Now the handler receives 'rw' (BX_READ, BX_WRTE, BX_EXECUTE) access type as parameter.
If returning a pointer to <addr> - itr is assumed that whole 4K page containing the <addr> could be accessed using the same pointer with offset.
You can return a pointer for READ/WRITE only and disallow execute, this is handled properly in the CPU code.
