ebbd952d3b Code cleananup: Since the Cirrus plugin device is only loaded in case the 
VGA extension "cirrus" is selected, there is no need to check this parameter.
TODO: Implement new VGA extensions (e.g. Voodoo Banshee, Voodoo3).

f31d062854 Added SDL / SDL2 specific multi-threading support. If one of these guis is 
enabled, the portable code is used instead of the pthread or win32 one.

0311f47bc3 Moved all Bochs event / wait functions required for multi-threading to a new

da48346f9d Implemented combined PCI / memory FIFO. This is required for running Voodoo1 
games / demos correctly on the Voodoo2 model. I noticed a small slowdown
(2 or 3 percent) on the Voodoo1.

e063d282ac Voodoo2 CMDFIFO fix and cleanup. 
- Fixed probing the CMDFIFO with Voodoo output disabled (send FIFO wakeup
  directly, otherwise driven by vertical retrace).
- Use the CMDFIFO member 'enabled' instead of reading the fbiInit7 register bit.
- TODO: The Voodoo2 freeze when testing a Voodoo1 demo is still not fixed.

7c3dafc7f5 Some Voodoo emulation fixes. 
- voodoo_init() must be called after initializing FIFO mutex.
- The 'op_pending' counter must be reset after resetting FIFOs.
- Fixed an MSVC warning and removed obsolete comment.
- FIXME: There are still some conditions that can freeze the Voodoo display.

1f85292418 Implemented memory FIFO to speed up the Voodoo1 emulation. The PCI FIFO with 
it's 64 entries is still not present, since it makes the emulation a few
percent slower due to the overhead of the FIFO code. The memory FIFO has 64k
entries and makes a speedup of around 75 % possible.

ea8bfca53f Two USB modifications requested by Ben Lunt. 
- usb_msd.cc: The Device Qualifier is valid for high speed devices only.
- uhci_core.cc: Don't report BX_DEBUG message if the current TD belongs to an
  async operation that is still not complete.

2a55ba0a39 Merge set of debugger improvements by Doug Gale <doug16k> 
Here is his original comment:

I have made several improvements in the debugger.
I have fixed several issues with proper handling of 64-bit addresses, and added support for 64 bit symbols.
I also have added several symbol lookups.

680189a548 Fixed Voodoo pixel clock calculation. 
- Now using float type for the 'clk0_freq' variable.
- DAC register 6 can switch to half pixel clock (ported from PCem).
- Writing value 0xf8 to PLL register 0x0e completes clock #0 setup.

4e80e2fbfc Started preparing the Voodoo code for the PCI FIFO / memory FIFO implementation. 
- Initialize the thread and event stuff for both Voodoo models.
- Rewrite of the event handling code to manage different events.

e187f3907a Removed Voodoo realtime option. Since the gui screen update timing is now 
controlled by the 'vga' option and Voodoo2 CMDFIFO thread has the best
performance with realtime mode disabled, this option is now obsolete.

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.

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.

3cee1f74ee Now using WIN32 event / wait functions in the Voodoo2 thread. I noticed a speed 
improvement of around 10 % (tested with donut demo only).
TODO: Use similar functions of the pthread library for improvements on other
platforms.

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).
