04c767d240 Some fixes for wx "second run" support. 2021-01-08 19:46:31 +00:00

5ffb319df1 Rewrite of the disk image mode handling. Disk image modes are now stored as
string constants instead of hardcoded values. Available modes are detected at
Bochs startup and stored in a string array before initializing options. In the
plugins case additional modes are read from the plugins list. If plugins are
off, the hdimage_locator_c registry is used. Related changes in all parts of
Bochs that need the hdimage stuff.
TODO #1: Network and sound drivers could be handled in a similar way.
TODO #2: Make disk image mode detection work again in plugins mode.

95d0a182af Some work on the disk image sector size option based on a patch by Ben Lunt.
- Implemented sector size handling in the ATA disk emulation. This feature
  still needs BIOS support to boot from a disk with big sectors.
- Enabled sector size support in the redolog_t class based disk image mode.
  The base class can handle 512 byte blocks only, but that doesn't matter since
  all valid sector sizes are multiple of it. So for now the growing, undoable
  and volatile disk image modes internally read/write 512 bytes per call.
- TODO: BIOS, bximage.

657cd05c0a Continued preparing hard disk sector size option in the hdimage code.
- 'flat' mode: disk image size must be multiple of sector size.
- 'concat' mode: each disk image size and lseek() offset must be multiple of
   sector size.
- 'sparse' mode: page size and lseek() offset must be multiple of sector size.
- TODO: 'growing', 'undoable' and 'volatile' mode: redolog_t class is still
  based on 512-byte blocks.
- TODO: 'vbox', 'vmware3', 'vmware4', 'vpc' and 'vvfat' mode have a builtin
  geometry. If other sector sizes are supported, it should be handled correctly.
- harddrv code now reports current sector size, but still panics for now.
- TODO: harrdrv and USB disk code, bximage, BIOS.

This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

400704d038 Added macro BX_FATAL() that works like BX_PANIC(), but with hardcoded action
"fatal". It can be used for all cases when there is no workaroud present to
avoid application crash or incorrect simulation behaviour. As a first step now
using BX_FATAL() for some data structure size and bit field errors.

16fb8317bd Fixed parameter handler issues found with runtime changes while cdrom tray locked.
- bx_param_num_c: set the value returned from the handler.
- bx_param_string_c: set the new value after processing the handler.
- harddrv param handler: check lock state of cdrom and modify value if true.

- renamed config parameter "i440fx_support" to "enabled"

- 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

9ee5a77747 - started implementation of sav/restore support for hard disk images using a
dummy parameter and it's save/restore handlers. Currently only the save
  support is implemented and the specific save function is only written for
  flat mode images (copies whole disk image file to the save/restore folder).

- TODO #2: add restore support (replace disk image file with the one from the
