existing "iolight timer" code in the hard drive code. If an LED is registered
with the "auto-off" flag, the device only needs to turn on the LED to indicate
data transfer. The LED timer in the gui code turns it off after 0.5 seconds if
it is not actived by another transfer. Added this feature to all network
devices.
- TODO #1: implement this feature in the USB host controllers
- TODO #2: the unused timer in the hard drive code could be used for the
emulation of seek functions
directly while parsing the bochsrc or command line. If plugin support is enabled,
the option could load all optional plugins, not only the ones supported before.
NOTE #1: The old option had all plugins enabled by default and gave the user
a chance to diable them. Now the plugins are only loaded if they
appear in the config line and they are set to "1".
NOTE #2: Loading a plugin that is controlled by a bochsrc option is possible,
but it currently leads to a panic, since the load command is still
present in devices.cc.
NOTE #3: The plugin init code creates the device object and registers the
optional plugin device. As an option, it can create config parameters
and register an option parser. The device init, register state and
reset is still handled in devices.cc, but in the order the devices
have been loaded with the plugin control.
NOTE #4: If plugin support is disabled, the plugin control only accepts the
devices listed in plugin.cc.
- plugin init of core plugins now fails if they are not loaded with the expected
type. For core plugins the load order is important and they cannot be handled
with the chained devices list (used for optional and user plugins).
- some additions for calling config.cc functions from a plugin device
turned off. Removed workaround code from devices.cc.
- removed 'pci_ide' plugin from the optional plugin control, since it depends
on the presence of 'pci' and 'harddrv'.
- define types for plugin init/fini functions
- use 'pci_rom_size - 1' as the mask for the offset address
- ne2k: memory handlers must be disabled if compiled without PCI support
- svga_cirrus: check for the PCI ROM size to make VBE work correctly
- added BX_INFO to the mem write handlers
For now it returns a flag that indicated that the device can receive data
from the eth module and flags for the device speed. TODO: Use this callback
in the eth modules before sending data to the device.
- another temporary solution for host from/to little endian conversion
- changed some variable types to bx_bool
- some other small cleanups
- TODO: add boot ROM support to all network devices
- TODO: add save/restore support, use Bochs function for host to little endian
data conversion, timers of networking modules 'vnet' and 'slirp' should use
the device speed instead of fixed 10 MBit
memcpy(). The reason for the failure is unknown. Using writePhysicalPage()
is safe, but slower and it only works on little endian hosts. On big endian
hosts the data block would be copied in reverse order. We have to check
whether or not this behaviour is expected for blocks > 8 bytes.
* if the image provides a geometry, always use it.
* if the cylinder value is set to 0 and the image supports autodetection,
calculate the cylinder value from disk size, sectors and heads.
* in all other cases the specified geometry is used.
* a panic only occurs if the image size is too small for the geometry.
* extra data past the end of the disk now causes an info message.
- TODO #1: 'flat' mode hdimage: read disk size of raw devices on Linux
- TODO #2: 'flat' mode hdimage: use geometry from MBR on image if present
- TODO #1: move shared stuff (e.g. creating TOC for image file) to the base class
to fix the temporary code duplication
- TODO #2: remove ASPI code for raw cdrom access on Win 98/ME after release
