50c1370216 Some work on the PCI devices code.

- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- Added new structure bx_pci_bar_t that contains all parameters related to the
  PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
  in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
  BARs and the ROM BAR. Writes to other registers are forwarded to the device
  specific PCI write handlers. Removed BAR and ROM BAR handling from the
  specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
  update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.

89353c8f4f Applied SF patch #539 (written by David O'Shea).
- Ported "hack for NE2000 with Netware 3.11" from an older QEMU version.
- Check if the TX packet is within memory bounds, otherwise PANIC.

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).

c897ffa619 Cleanups in the Bochs system timer code
- Now using macro DEV_register_timer() in all devices and lowlevel modules.
- Removed unused timer stuff from the plugin.cc/.h code.

d46a9b7205 Some work on the PCI devices code.
- Since the pci_read_handler() method is identical in most devices, move it
  to the base class to reduce code duplication. Only the 'pcidev' device has
  it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.

425688d014 Using bx_param_string_c method isempty() simplifies code and fixes panic in NE2000 ISA. 2014-05-09 13:49:42 +00:00

76a03aa1f0 Networking-related fixes
- bx_param_string_c method isempty() didn't work for raw byte strings. Now using
  it to check whether or not the current value matches the initial one. The
  parameter handling of the network adapters now use this method to check if
  the MAC address is already initialized to avoid incorrect BX_ERRORs.
- small documentation update

c6dd095321 Added new method for the init of the readonly registers in the PCI config space
and cleaned up the PCI devices code.

ae659d14fd Changed initial value of the parameter "enabled" to 1 for network, sound and
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.

17970857b8 added new bx_param_string_c methods isempty() and sprint()
- isempty() returns 1 if string length is 0 or string has special value "none"
- sprint() copies the formatted / converted string into a buffer
- use new methods in some parts of the code (TODO: win32 dialogs)
- check for the special value "none" to avoid failures

b1cc217ea8 parse mouse and ata resource bochsrc options using the parameter list
- fixed possible segfaults in the new parser code
- use the new parser code partly for the ata device and nic options

a5e5ac69b0 save the network configuration lines using the parameter tree
- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code

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

MSVC plugins)

db633275b0 - several improvements to the optional plugin control
- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
    configuration when using the plugin name "*". The 'load' value 1 makes
    sure that all plugins with the value 1 are loaded. The 'load' value 0
    unloads all plugin with the value 0 (marked for removal).
  - add the default set of plugins to the 'plugin_ctrl' list and load all these
    pre-defined optional plugins before parsing the configuration.
  - special wx case: verify plugin configuration before showing the plugin
    control dialog and before initialising hardware.
  - device plugins that have been loaded, but not configured now set their
    plugin control value to 0. Added the plugin unload check before signalling reset.

f65c4e66b8 - debugger command 'info device': implemented support for additional arguments
- 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()

bdfe4ae1bb - added debug_dump() (prints the same as 'info ne2k' without arguments)
- removed FILE parameter from print_info() (unused - since dbg_printf() doesn't
  need it)
- converted tabs to spaces
- TODO: implement 'info device' with optional arguments to get rid of the
  print_info() method
