the display adapter code. When ready, the common gui code should handle it
completely. The snapshot handler should set a flag 'snapshot_mode' and then it
should force a display update. The graphics update code should be redirected to
some code that 'draws' to a snapshot buffer. These first steps are done:
- store some guest display settings in the gui code (text / graphics switch,
x / y resolution and bpp)
- split 8 bpp palette update code in a common and a specific part and store the
palette values in the gui code
These hdimage modes are now supported: flat, sparse, growing, vmware3, vmware4
und vpc. The image mode is auto-detected, so no change of configuration syntax
is necessary (TODO: documentation update). Example:
ata0-master: type=disk, mode=volatile, path=vmware4-test.img
- redolog class: added support for opening redolog file in read-only mode
- open backups for header check in read-only mode (growing, undoable, volatile, vpc)
type of the r/o disk for the undoable / volatile mode. The format check code
is currently written for flat, sparse and growing images. The undoable and
volatile mode now cause a panic if the r/o image mode is unsupported.
- TODO #1: rewrite the header checks for vmware3, vmware4 and vpc images to make
them usable for autodetection.
- TODO #2: add support for other types of r/o disks in undoable/volatile mode.
- TODO #3: add an image mode 'auto' for the supported types (NOTE: unknown images
can be treated as flat ones if their size is multiple of 512).
- don't enable Voodoo mode if hSync or vSync are still 0 to avoid Bochs crash
(division by zero error)
- handle PCI register 0x40 (initEnable)
- fixed reported display size
time if requested (reduces code duplication)
- 'vpc' image mode: moved header check to a separate function that opens the
file, checks header/footer and returns disk type (if requested)
- implemented restore function for 'vpc' mode images
- gui: updated yes/no dialog message after saving state
- save/restore documentation update (TODO: developer doc)
be set for "true", but variable "lfb_enabled" wasn't correctly set up.
- TODO: check the whole Bochs code for the correct usage of variables saved
with bx_param_bool_c.
On win32 the native CopyFile() function is used. The restore function should
work this way: coherency check (if necessary), close current image, copy saved
image from restore path (overwrites existing one), finally re-open image.
- implemented restore function for 'flat' and 'undoable' mode images
- set timestamp of r/o disk in volatile mode, too (for save/restore support)
- TODO: save state function for the remaining image modes, restore support
undoable, volatile)
- TODO: save state function for the remaining image modes, restore support
- save/restore: when saving binary data to a file, use the full parameter path
(except "bochs." prefix) as the file name to avoid overwriting duplicates
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 #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
save/restore folder)
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
- Cirrus adapter needs to set the last resolution and BPP for VGA override
- TODO #1: move display adapter code to iodev subdirectory 'display'
- TODO #2: add 3dfx Voodoo Graphics emulation
add the LGPL to usb_hid.cc
- moved Ben's comment to usb_uhci.cc, since this file contains most of his
initial pciusb patch
- TODO: implement full USB keyboard support (port from QEMU)
been ported from QEMU and originally have this license
- TODO: The QEMU people should verify the changes and tell us if something is
missing. Bochs 2.6 will be released after everything has been confirmed to
be okay.
