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
16bd4c6401 - added pci_base_address array to bx_pci_device_stub_c and use it in most of the PCI devices instead
of several base address variables (ne2k still uses base_address for both ISA and PCI)
2011-06-25 12:43:27 +00:00
Volker Ruppert
2137c8bd81 - moved pci_conf array as a protected member to the PCI device stub class (exists in all PCI devices) 2011-06-23 15:56:02 +00:00

1df7a9131b Fixed possible buffer overflow causing segfault or memory corruption. The
buffers are not large enough for the maximum sector count in LBA48 mode. Now
resetting buffer pointers after processing a PRD (and move remaining data if
necessary). This should fix the SF bug items #3190970 and #3077616.

e34262bc7d - fixed regression caused by SF patch #2812936
* buffer size must match the IDE specs to transfer max. 255 sectors
  * resetting buffer pointers during IDE command is invalid

46265689aa - PACKET-DMA feature now supported by all ATAPI commands
* don't panic if byte count is zero in PACKET-DMA mode (the specs say that
    byte count is used for PIO modes. The behaviour in DMA mode is not
    mentioned, but seems to be ignored in that case.)
  * pci_ide: initialize sector size with the BM-DMA byte count (disk read
    commands will overwrite this value, some ATAPI commands are using the
    original one.)
  * non-disk-read ATAPI commands simply copy the buffer in DMA mode

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

190b9391cf - delete the device object in the plugin_fini() function of each plugin device
(TODO: find a way to call plugin_fini() for non-core devices if plugins are
   disabled)
- set the device pointers back to stubs after unloading plugins
- added debug message "Exit" in all device plugin destructors

15efba10dd - ata/atapi options rewritten to a parameter tree
- siminterface get_param_*() methods num support a base parameter like the generic
  get_param() method
- new parameter lists now also have a generated id
- test function print_tree() now handles enum parameters correctly
- proposed parameter tree updated

a57464cb54 - Busmaster DMA fuction implemented, but disabled for now. BM-DMA works in Linux,
but failes in Win98 with this code, so I decided to disable it.
- BM-DMA register read messages changed to BX_DEBUG

ae180cc46a - pci slot register mechanism added
* up to 5 slots can be specified with the 'i440fxsupport' config option
  * the pci slot number are hardwired to pci device numbers
  * the 'devfunc' value is returned the calling device (useful for multi-function
    devices)
  * the core of the i440FX chipset is hardwired to pci device 1 + 2; usb is still
    optional and appears at device 1, function 2
- ne2k: enable pci features if connected to a pci slot
- ne2k: asic data port supports 32-bit access if ne2k-pci is active
- pci2isa: improved error messages for ELCR1 and ELCR2

5873b26a82 Speed up compilation process.
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
