07f32da5a7 Some plugin related fixes.
- Fixed loading of all plugins with one type using wildcard.
- Reduced maximum length of line when listing available modules for hdimage,
  network and sound.

744efe9c22 The hdimage, networking and sound code now also use PLUG_get_plugins_counrt()
and PLUG_get_plugin_name() in case plugin support is disabled. Removed
temporary compatibility code from the self-registering stuff.

0d425037df Improved plugin type detection at Bochs startup.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
  reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
  loading (currently only the voodoo plugin provides two types).

45e03f9572 Changed bx_bool to bool type in the harddrv, cdrom, hdimage and sound code. 2021-01-31 15:44:39 +00:00
Volker Ruppert
8db0a2b001 Replaced the plugin init / fini functions with one single function called
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).

d61e3eca9b Moved image creation code for sparse, growing, vmware4 and vpc mode images from
the main bximage code to the device_image_t class / file it belongs to (enabled
in the BXIMAGE case only).

59ee157575 Some work on the hdimage code for bximage support.
- Enabled self registering code for the bximage case to simplify mode detection.
- Fixed vpc image format check for mode detection case.

afcda20b83 Some work on the hdimage mode detection code.
- In plugin mode make sure all hdimage plugins are loaded for mode detection.
- Implemented image mode detection via hdimage_locator_c.
- TODO: use the new code for bximage, too.

127fd003cc Some more work on the Bochs plugins support.
- Added support for loading all plugins of one type using wildcard "*".
- Unloading no longer removes the plugin object. Now the member "loaded" is
  set to 0 and the type of a device plugin is reset.
- Added plugin_cleanup() function to remove plugin objects on Bochs exit.
- Some other related cleanups in the plugins code.

7c8748a661 Removed stub for the "external" disk image mode. It was designed for
implementing disk image support with an external C++ class. With the new code
it's now easier to implement support for additional disk images formats, so we
don't need the old stub anymore.

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.

4f311f0618 Some work on the Bochs plugins support.
- Added suffix "_gui" to the base name of display library plugins.
- Added new function plugins_search() that browses the plugin folder(s) and
  detects the type from the library name. Plugins with no prefix or suffix are
  treated as i/o device plugins. The plugin_load() function uses this database.
- Some related fixes and cleanups.

c99bd49f34 Some work on the hdimage plugin support.
- Renamed vpc-img.* files to vpc.* and removed hack for image mode name conversion.
- Added suffix "_img" to all disk image mode plugin base names. This is important
  for the future implementation of a plugin enumeration at Bochs startup.

b880fb2975 Rewrite of the hdimage plugin code.
- Common hdimage code, lowlevel cdrom code and the classes for the Bochs "own"
  image modes (e.g. flat, sparse, growing") are now a part of the Bochs core.
- All classes for image modes present in separate files are now built as
  plugins with the same self register mechanism as network, sound and usb
  modules. Defined new plugin type PLUGTYPE_HDIMAGE.
- Temporarily disabled the base image format detection of the undoable/volatile
  modes for the "external" modes in the plugins case.
- TODO: Bochs should know about all of the available plugins and their
  capabilities right after startup, but before the configuration stage.

4b27cc1103 Removed member 'extension' from direntry_t structure and increased 'name' size
to 11. Accessing 'extension' data using 'name' index is illegal and at least
gcc version 7.5.0 has produced incorrect code for creating short file name.

038ebf5815 Replaced deprecated function GetVersionEx() with newer code based on Windows
Dev Center example (expecting Bochs is not used on hosts older than XP).

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.
2018-03-27 17:47:46 +00:00
Volker Ruppert
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.

7fd9194d81 Implemented lock mechanism for hard disk images (fixes SF bug #605).
- Create a file with image name plus extension ".lock" if an image is opened
  in read/write mode. This file will be deleted after closing the image.
- Check for a lock file before opening an image and fail if it exists.
- Check for a lock file before creating a undoable/volatile redolog file and
  fail if it exists.

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.
