9a1668ac36 First version of the Voodoo2 CMDFIFO thread using "pthread cond" code on
non-WIN32 platforms instead of BX_MSLEEP(). The donut demo is once again a
little bit slower, but on other tests the IPS values are still okay. Cleaned
up the code a little bit and added save/restore stuff for the new code.

6361386e8b Reverted BX_LOCK/BX_UNLOCK changes from previous commit (don't lock CMDFIFO
completely while running cmdfifo_process()). The donut demo is now a little bit
slower on Linux host, but other test cases are faster again.

fcb5f6d1d3 Voodoo2: Now only start processing of the CMDFIFO at the vertical retrace.
I noticed a speed improvement of around 10 % (tested with donut demo only).

593141603d Small change in the non-WIN32 Voodoo2 thread code: Process all complete command
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.

7b5eca0cf2 Minimal improvement in the CMDFIFO code: calculate needed depth for current
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.

d22cdbdbf7 Some work on the bxhub utility.
- 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).

bdd8875692 Reverted BX_THREAD_KILL() changes in the lowlevel sound code. Now using control
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.

bd1eb0f862 Rewrite of the USB devices plugin code similar to the network driver code.
- 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.

c160fd4830 Bochs thread handling improvements:
- 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.

Volker Ruppert
da489b91ce Implemented CMDFIFO type 3 data support using some pieces of code from file
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...

Volker Ruppert
6265976a2c Some work on the Voodoo2 CMDFIFO support.
- 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.

8b96faf99e Some work on the timing code of the Bochs display adapters.
- 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.

- 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.

f4bfb6353f - Some work on the Voodoo Graphics emulation
- 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.

915746a1fd Fixed slirp user-mode networking support on Cygwin 64-bit.
- 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.

Volker Ruppert
1d27d67ccd Added initial version of the High Precision Event Timer (HPET) ported from Qemu.
- 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.

e023b5896f Partial rewrite of the optional keyboard handling. Now the BX_KEY_* events are
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.

18e138b0b4 Fixes and improvements for the network plugins changes in previous commit.
- 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.

d6166344eb Added ethernet module 'socket'. designed to connect two Bochs instances with
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

449c8ae620 Some more fixes in the new sound plugins code.
- 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.

f844e846b7 Added PCM output data resampling in a separate thread. The resampler requires
either libsamplerate or the SoX resampler library installed. If not installed,
the data is only copied to the output buffer and sample rate of the output
driver is changed similar to legacy code. Related changes:
- Added check for libsamplerate or SoX resampler header files in configure
  script.
- Added functions for converting source format to float (requied by resampler)
  and float to output format.
- Added support for float type data in the audio buffer code. Buffer chain #0
  receives float data from sendwavepacket() and buffer #1 receives data for
  mixing and output in format "16-bit signed little endian stereo".
- ALSA: Disable builtin resampling feature if resampler is present to avoid
  doing it twice.

c3b608a3c9 Implemented USB remote wakeup mechanism.
- Extended USB callback definition to support different event types sent from
  device to HC. Currently we only have the two events "async completion" and
  "remote wakeup".
- Implemented event handlers in the UHCI, OHCI and EHCI. For the EHCI version
  we currently have no test case.
- The external USB hub now uses this feature at device connect/disconnect.
  Now the device change on the hub is correctly detected by the guest OS.
- TODO #1: remote wakeup and async completion for the xHCI.
- TODO #2: event handler for the external hub to make a USB device work on
  a chain of hubs.

3fd323abc5 USB xHCI endianness and warning fixes
- use get_dwords() and put_dwords() from EHCI sources for reading / writing

Volker Ruppert
17b4e65bef The save/restore list for USB devices is now cleared by the device destructor
instead of the hub's remove_device() method. The external hub removes connected

are present on external hub.
2016-11-12 14:17:46 +00:00
Volker Ruppert
364bf9362c Changed handling of unsupported/invalid device speed setup. The UHCI core now

to continue.
2016-11-11 16:11:52 +00:00
Volker Ruppert
6ba530e461 Ported most of the remaining EHCI methods to Bochs, including some ugly hacks.
Asynchronous transfers are not yet working properly (tested with USB disk device

256fd99d12 USB floppy "format unit" timing implemented similar to read/write timing.
Added latency time for the "implied seek" of read/write/format commands. Both
features can be used when asynchronous packet handling is available. Some
related changes in the non-async read and write code.

0b432b313f Added seek emulation support for USB harddisk reads and cleaned up the
MSD / SCSI code.
TODO list (async packet and seek support):
- seek emulation for USB harddisk write commands
- seek emulation for floppy
- async packet support for UHCI and xHCI
- improve and clean up OHCI async packet code

491dc311ca Some work for asynchronus USB packet handling (needed by disk/cdrom seek emulation).
- Common USB code prepared for async USB packet handling (ported from an earlier
  Qemu version).
- Added simple async packet handling to OHCI (partly ported from earlier Qemu).
- Implemented USB cdrom seek emulation for hubs with async packet support. The
  legacy code is still present for hubs without this feature.
- For UHCI and xHCI the callback is set to NULL to force the usage of the
  legacy cdrom read code.
TODO: clean up OHCI code, async support for UHCI and xHCI, seek emulation for
USB harddisk and floppy.

6dbd4c37a9 Some USB debug output (packet dump) changes
- rewrite of usb_dump_packet(), execute code only if debug output is enabled.
- OHCI: removed packet dump, it should be done in the devices code if necessary.

f54feb5b91 Some variables should not be handled by the xHCI internal save/restore, moving
them out of the hub structure.

2dbfae1b1c Fixes and improvements for the USB cdrom runtime options.
- Add a special list to the MSD state and add pointers to the runtime-only
  options for the cdrom. The restore handler of this list calls runtime_config()
  to make sure the media path and status are correctly updated.
- Registering a runtime config handler for the USB cdrom is not necessary since
  runtime_config() is always called from the hub it is connected to.
- Restore a string parameter value only if it's different from the initial one.

7da8cfa4b0 Fixed save/restore support of the USB subsystem when using an external hub
with devices conected at runtime.
- Added restore handler support for the bx_list_c class. If a handler is
  registered, it will be called after restoring all of the list's members.
- USB hub: add special lists to the port state and add pointers to the
  runtime-only options for each port. The restore handler of this list calls
  init_device() to make sure all connected devices can be restored.
- Call restore_logopts() after restoring hardware to make sure all saved
  modules have been created.
- TODO: the USB cdrom also needs a fix for it's runtime-only options.
