- 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
and the supported ethernet modules
- renamed eth.* files to netmod.*
- pseudo-device plugin implementation similar to 'soundmod'
- TODO: move sound, net and usb stuff to a separate subdirectory of iodev
with the host time. After using a runtime config dialog or save and restore
simulation, this behaviour makes the PIT clock and the VGA update timer
running way too fast until it's back in sync. Now the elapsed time is stored
in the variable 'real_time_delay' and it is used to let the PIT clock run at
realtime speed, even if it is out of sync.
- added new method get_vga_pixel() that read the color value from EGA/VGA memory layout (moved from
display update code and now also used for snapshots)
- minor code cleanups
'vga_update_interval' option. The screen update frequency is still based on
the emulated clock unless the realtime sync is enabled with the 'clock' option.
TODO: rewrite the virt_timer code to support realtime screen updates
independent from 'clock' setting.
- fixed changing parameter 'update_freq' at runtime (timer object and blink counter)
parameters (path + status) have been set. TODO: implement this feature for the floppy, too.
- call update_drive_status_buttons() from update_runtime_options() to reduce the number of calls.
Now call update_runtime_options() from the gui floppy / cdrom handlers after closing dialog.
duplicate log prefixes on Windows if both IDE and USB cdroms are used in plugin mode. Windows also
requires the cdrom base class and the init_cdrom() method to link and work correctly.
- don't add reserved bitfields to the save/restore tree
- some fixes for big endian machines
- TODO: init max_packet_size in USB devices, find test case, ...
- added main source file usb_xhci.cc
- TODO: finsh work in register_state()
- TODO: USB devices: initialize max_packet_size
- TODO: test case for xHCI wanted
- using the same init() method for all display adapters
- new method protected init_standard_vga() for the shared vga core
- new method init_vga_extension() implements the extended features
- moved loading of vgabios image for the ISA case from main.cc to the vga init code
Sebastian Herbszt). TODO list:
- modify LGPL'd VGABIOS to make it work with SeaBIOS
- modify Bochs BIOS to set up the legacy address 0xc0000
- implement PCI ROM support in the cirrus device
- move load_ROM calls to the display adapter code to handle the ISA case
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
each other. Devices can register a handler to update it's state after runtime
configuration. The new method update_runtime_options() executes all registered
device handlers before the simulation continues.
- USB host controllers now using the new mechanism to handle the runtime device
change (replaces the previous timer-based implementation). TODO: floppy and
cdrom could use this feature, too)
- improved USB device change messages
makes screen updates independant from the ips value if the realtime
synchronization is enabled ("clock: sync=[realtime|both]").
Thanks to Stanislav for pointing me to this direction.
must ignore writes to it (fixes "garbled W" bug in Win95 with Cirrus ISA)
- fixed "inverted transparent colorexpand" bug (pointed me to the above issue)
- TODO: IE 5.5 startup window is still not okay
foreground color. This fixes the "white text" bug in original Win95 (A) with
the Cirrus ISA driver.
TODO: fix the "garbled W" bug (related to "dword granularity").
The ACPI support is always automatically compiled in if PCI is compiled in.
The ACPI still could be disabled using .bochsrc 'plugin_ctrl' option.
Updated CHANGES and docs as well.
Upon investigation the problem is easily fixed in bx_serial_c::rx_timer_handler():
<snip>
ssize_t bytes = read(socketid, &chbuf, 1);
#endif
if (bytes)
{
BX_INFO((" -- COM %d : read byte [%d]", port+1, chbuf));
data_ready = 1;
}
<snip>
I think this means the extra check above will give no noticeable degradation of performance, so hopefully this can be applied to SVN. It would avoid screwing up a running instance of Bochs when a remote network client unexpectedly disconnects from the COM1 tcp port.
Also some cleanup in serial.cc code.
ES1370 emulation to use it.
TODO #1: implement real sound input in the lowlevel sound modules
TODO #2: implement sound input in the SB16
TODO #3: rewrite sound output code to use the same API
- es1370: fixed transfer size for the ADC channel
- es1370: call startwaveplayback() when the DAC2 channel is activated
- added missing change to BX_SUPPORT_SOUNDLOW
- changed type of variable "stereo" to bx_bool
- minor other changes
DAC2 is sent to the lowlevel sound module. DAC1 and sound input (ADC) are not
yet supported. Also unsupported: CODEC (mixer), UART (MIDI) and legacy support.
Sound module selection in configure script now no longer depends on SB16 and
uses autodetection only.
- fixed segfault when saving bochsrc
--enable-vbe is now deprecated and the symbols BX_SUPPORT_VBE and
BX_SUPPORT_PCIVGA have been removed. To enable VBE support, the bochsrc option
"vga: extension=" must be set to "vbe". If PCI is present, you can assign the
"pcivga" device to a PCI slot.
