81f55b5be7 improved the fix for busmaster DMA transfers from device to memory done by Volker 2011-12-02 19:41:54 +00:00
Volker Ruppert
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.

525e5a46f7 - moved array 'rom_present' to the memory class and initialize it at startup. 
This is required for the "second run" feature of the wx port. The simulation
  thread can be run multiple times without restarting the application.

fda4d38959 32-bit systems have a problem to allocate large amount of physical memory for Bochs simulation which makes simulation with 4G address space virtually impossible. But in most of the cases when 4G physical address space defined - it is not touched by default on every run so it is possible to allocate only really accessed blocks. This commit made all necessary preparations for it. 2008-04-17 14:39:33 +00:00

071c5c1a26 A lot of changes but everything is really trivial. 
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
