- Modified win32 thread macros to use the handle instead of the id.
- Added new macro BX_THREAD_KILL to terminate threads.
Voodoo thread changes:
- Let the cmdfifo_thread sleep while the CMDFIFO is disabled.
- Kill the cmdfifo_thread in destructor and removed old thread control code.
- Added capability to save/restore float type values in paramtree / siminterface.
- Added Voodoo2 triangle generator data to save/restore list.
- Implemented bitBLT function "SGRAM fill".
- Minor other changes and cleanups.
- TODO: remaining bitBLT functions, thread handling improvements.
voodoo.h.txt which was a part of the original voodoo patch for DOSBox.
Some Voodoo2 specific parts were not integrated in the main patch file. I guess
they have been removed since Voodoo2 support was incomplete (2D stuff missing).
TODO: Voodoo2 2D support (bitblt engine), more testing, code cleanup...
- Added CMDFIFO thread similar to the sound output thread.
- split register write function in 2 functions: register_w_common() handles
the CMDFIFO writes and valid registers in CMDFIFO mode. It forwards write
accesses to other registers to register_w() (Voodoo1 and non-CMDFIFO mode).
The CMDFIFO thread also calls register_w() when processing data.
- The CMDFIFO thread processes all data, but it does not yet execute type 3
requests (extended triangle generator missing).
- TODO #1: implement Voodoo2 specific triangle functions (for CMDFIFO).
- TODO #2: implement 2D bitblt engine.
- Zero out voodoo device state in init().
- Added the CMDFIFO state to save/restore list.
- Added CMDFIFO register handling in read/write functions.
- Added new function cmdfifo_put().
- TODO: CMDFIFO thread.
- Fixed normal register access in CMDFIFO mode.
- Implemented cmdFifoBaseAddr register behaviour.
- Write CMDFIFO data to FBI memory (has no effect yet).
- Changed some log messages to BX_DEBUG.
- Report unimplemented Voodoo2 registers.
- TODO: Add FIFO thread to process the CMDFIFO data.
valid. The hRetrace value can be set now, since Bochs no longer crashes.
TODO: Implement enough of the FIFO stuff to make the Win9x driver for the
Voodoo2 work.
host when the mouse is captured and in fullscreen mode. This is useful if the
guest is also a Windows version. These changes are based on the rejected SF
patch "disablesystemhotkeys". But instead of disabling the hotkeys completely,
the events are sent to the Bochs keyboard.
- Voodoo: Use the VGA/Cirrus timers to drive the gui screen update.
The vertical retrace emulation is still driven by a separate timer.
- VGA/Cirrus: Since we are using the virtual timer, we also have to read
time_usec() from it.
- vgacore: removed unused timer methods.
- prepared hRetrace value implementation (cannot be enabled yet, since the
driver passes this test and gets confused in next stage (segfault).
- Detect CMDFIFO access (not present yet).
- Report disabling Voodoo graphics mode.
- TODO #1: Fix Voodoo2 to make it usable.
- TODO #2: Split update code and drive gui screen updates from the VGA timer
(finally remove new realtime option again).
- Since we are using the virtual timer, so we have to read time_usec()
from it, too (TODO: realtime mode is hardcoded, maybe add an option).
- Voodoo1 and Voodoo2 have different timing register widths.
- Fixed vertical retrace value returned by get_retrace().
- Prepared separate hvRetrace register (TODO: hRetrace).
- Store the Voodoo model in structure bx_voodoo_t.
- The PCI initEnable register of the Voodoo2 model has a read-only secondary
revision ID in bits 12..15. Now the Voodoo2 is correctly detected by the
Windows driver, but display is not yet working (blank screen).
- Reset now disables VGA override.
- PCI: Moved PCI device base class methods to the end of file devices.cc and
re-define LOG_THIS to use the correct log module and prefix.
- Enabled Winsock2 usage and define _WIN32 symbol for Cygwin (both 32 and 64 bit).
- Changed include order in some files to resolve conflicts.
- Modified some data types to fix errors and warnings.
- Added workarounds for the incorrectly defined symbols FIONBIO, FIONREAD and
EWOULDBLOCK.
- Verified slirp usability with Cygwin 32-bit, MinGW/MSYS and MSVC builds of
Bochs. Other ports should not be affected.
- socket: Define the FIONBIO workaround for 64-bit Cygwin only.
- slirp: Don't mix usage of WIN32 and _WIN32 definitions.
- TODO: The slirp module still fails at UDP socket creation when Bochs is
compiled in Cygwin64.
- slirp: Increment IP packet ID outside of htons() to avoid undefined behaviour.
- socket: Workaround for a bug in the w32api code that generates a constant
with wrong value. Setting up our own FIONBIO fixes the panic.
- TODO: The slirp module still fails when Bochs is compiled in Cygwin64.
NOTE: networking still fails when compiled with Cygwin ('socket' mode fails
to set up non-blocking i/o / 'slirp' doesn't complain, but fails to connect
the internet).
latest BIOS images 32-bit and even 64-bit guest OS's are known to boot inside
of Bochs without hacking. This legacy hack could be removed after next release
if nobody complains.
- Created framework based on our I/O APIC code and ported HPET core from Qemu
with some required changes for the Bochs timer and IRQ handling.
- Enabled HPET-specific code in the ACPI and rombios32 sources and generated
new ACPI table with iasl.
- The HPET device plugin is now always loaded if the i440FX chipset is selected
(same as ACPI). We have to rethink this when we have implemented a more
modern chipset.
- TODO: Rewrite of the virtual timer code for nanosecond support to make the
realtime synchronization possible with HPET.
directly sent to the optional keyboard (USB keypad). It is now independent
from the legacy keyboard and the check for supported keys is simplified. The
legacy keyboard still receives the unhandled key event, but now sent from the
common devices code.
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.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
- Using bochsrc option "load32bitOSImage" now causes a warning. It is not
maintained yet, not documented and we don't whether it is used or not.
I guess it was designed to boot a real 32-bit guest OS when the Bochs BIOS
wasn't able to do it.
- Added config option --enable-busmouse to all shortcut scripts. We have two
usable models present now (tested with Win95).
- Added warnings for currently not maintained features in the configure script,
the bochsrc sample and the user doc.
- Removed detection of deprecated bochsrc options "i440fxsupport" and
"vga_update_interval".
- Legacy bochsrc option "user_shortcut" is now deprecated.
- Removed deprecated configure option --enable-misaligned-sse from user doc.
- Updated some TODO items.
- Makefile: cleanup of the 'clean' target (adds missing 'bxhub').
- configure script: create cpudb subdirectories if necessary for building
outside of the source tree.
- cpudb Makefile: clean object files from new location.
- In "non-plugin" mode loading and unloading network module is not necessary.
Now enabled loading for the plugin mode only and removed unloading function
for that case. The "pseudo plugin" entries of the dummy entry points are
necessary to make sure the self-registering network driver objects are not
optimized out.
- slirp / vnet: Since the plugin init function is not called in non-plugin
mode, revert the instance count init change.
- Fixed a makefile dependecy.
- TODO: Implement self-registering objects in the sound driver code.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved network module base classes and module handling to the Bochs core.
Now loading network driver plugins in netmod.cc.
- Moved shared networking code used by the 'vnet' driver and 'bxhub' from
netmod.cc/.h to new files netutil.cc/.h.
- Created separate plugins for each network driver implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_NETWORK.
The format of the 'ethdev' string must be 'host:port' to use this feature.
Using the port number only for connecting 'bxhub' on the same machine is still
supported.
- Small changes to avoid crash after failure.
- Several cleanups in the socket mode.
- Fixed reporting active mode after init is done.
- Reporting sent/received byte with BX_DEBUG.
- The 'vnet' module now uses the 'script' parameter for an alternative log
file name.
- Renamed log file names in some networking modules (replaced 'ne2k' by a name
related to the module name).
- Documentation updates (networking stuff and cmosimage).
- Increase maximum number of Bochs client sessions to 6.
- Define bx_devmodel_c to 'void' for the bxhub case to simplify netmod code.
- Minor cleanups in bxhub and related vnet code.
- According to the specs masked edge-sensitive IRQs are not held pending.
- Print BX_DEBUG message in set_irq_level() only in case of level change to
avoid flooding log file.
- eth_socket.cc: Added missing winsock init.
- bxhub.cc: Added missing CDECL macro to the signal handler.
- Added some definitions for non-Windows platforms similar to the serial and
rfb code.
- bxhub.cc: Put all client data in a structure and added send_packet() function.
- bxhub.cc: Added SVN ID line.
- netmod.cc: Changed some DHCP messages to BX_DEBUG.
- eth_socket.cc: Minor cleanups.
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
stuff similar to the work done with the sound drivers.
- Builtin sound driver plugin support should depend on BX_SUPPORT_SOUNDLOW.
- Added some symbols required for the MSVC plugin of sound driver "file".
- Clean up threads and audio buffers only when shutting down the primary sound
driver (pcm_callback_id >= 0). Fixes crash on exit with wavemode 3.
