packets and then always sleep for 1 millisecond.
TODO: The first tests with pthread_cond_* stuff showed a slowdown of approx.
10 % compared with the IPS value of the current code.
command and execute it when there is enough data present (code partly ported
from voodoo.h.txt).
TODO: Use "wait for event / condition" functions instead of msleep() if there
is a performance improvement with it.
- Added DNS service support for the server "vnet" and connected clients.
- Added command line option "-loglev=" to control whether or not there is
BX_ERROR, BX_INFO or BX_DEBUG output. Default value is 1 (BX_ERROR only).
variables again to let the threads end normally. Re-implenented the method
closewaveoutput() for some modules, move the destructor code to it and call it
after leaving the mixer thread. This fixes a deadlock in the "soundwin" module
if Bochs is compiled with plugin support.
- usb_common: init_device() now splits device name and primary option before
detecting device type.
- usb_hub: now completely handle port option in constructor.
- plugin.h: removed obsolete defines.
- Removed "pseudo device plugin" containing common code and all connectable
USB devices.
- Moved USB device base class and module handling to the Bochs core.
Now loading USB device plugins in usb_common.cc.
- Created separate plugins for each USB device implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_USBDEV.
- Added entries for the non-plugin case similar to the network and sound stuff.
- 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.
- 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).
- 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.
