Threading VU1 took a lot of rewrites and new code to make possible (MTGS, microVU, gifUnit...), but we finally got to the point where it was feasible, and now we've done it! (so now everyone can stop complaining that pcsx2 only takes advantages of 2 cores :p).
The speedups in the games that benefit from it are great if you have a cpu with 3+ cores (generally a 10~45% speedup), however games that are GS limited can be a slowdown (especially on dual core cpu's).
The option can be found in the speedhacks section as "MTVU (Multi-Threaded microVU1)". And when enabled it should should show the VU thread-time percentage on the title bar window (Like we currently do for EE/GS/UI threads).
It is listed as a speedhack because in order for threading VU1 to have been a speedup, we need to assume that games will not send gif packets containing Signal/Finish/Label commands from path 1 (vu1's xgkick). The good news is very-few games ever do this, so the compatibility of MTVU is very high (a game that does do this will likely hang).
Note: vs2010 builds and Linux builds need to be updated to include "MTVU.h" and "MTVU.cpp".

Pcsx2 now has a gifUnit class which acts like the ps2's gif and executes a single gif transfer at a time (and performs path arbitration according to priority and path3 slicing).
This new code is generally a speedup for most games. Particularly VU heavy games like GoW.
This revision breaks old saved state compatibility so don't update if you wish to keep playing with your old saved states.
Leave comments if this revision fixes or breaks anything...
Message to GS Plugin authors:
This new code now uses only 1 gif callback to transfer data to the gs plugin (GSgifTransfer).
pcsx2 also is garaunteed to send full GS primitives to the plugin. So you don't have to account for partial-transfers anymore.
Thanks goes out to shadowlady who tested around 500 games for me :D
Note 1: The old gif code is still in this revision, and can be enabled by the USE_OLD_GIF macro. The old code will be deleted soon.
Note 2: This revision also enables assertion dialogs in devel builds, and changed a lot of assume cases into assertions.

* Added logging of host operating system and physical ram to startup.
* Removed "PhysicalCores" stuff from both x86emitter and startup logs -- physical cores is losing its relevance with all the new AMD and Intel chip designs.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4048 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added __fi and __ri, which are abbreviations for __forceinline and __releaseinline.
* Added some static qualifiers to functions in mVU, MMI ops, and others where appropriate.
* Removed some unnecessary __fastcall qualifiers (since GCC gets funny sometimes when you combine __fastcall and inlining).
* Made _1mb, _16mb, _1gb values common to all emulation code (moved from newVif/mvu to Common.h) -- they're useful! :)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3624 96395faa-99c1-11dd-bbfe-3dabce05a288
* Remove some dangerous uses of pxAssume -- pxAssume should only be used for simple in-place operations, and should never call functions (my fault too, I was the one who was using it wrong).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3410 96395faa-99c1-11dd-bbfe-3dabce05a288
DevNote: I could have left the code for the freezes in, except I *really* don't want us to ever have to resort to using such a system ever again in the future. For anything. (its just not safe on modern optimizing compilers)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3392 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added 3-state checkbox support to pxCheckBox.
* Fixed some buggy behavior when closing PCSX2 with either main window or console window minimized (window positions would get screwy)
DevNotes:
* Moved ImplementEnumOperators macro to Common headers and improved it a bit.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3220 96395faa-99c1-11dd-bbfe-3dabce05a288
* Various small cleanups to emitters and microVU's regalloc code (no functional changes)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3162 96395faa-99c1-11dd-bbfe-3dabce05a288
newVif:
* Bugfix to HashBucket::find() cuts microprogram caches misses in half.
* Dynarec version now uses alternating XMM registers for unmasked unpacks (very minor speedup, ~1%).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2397 96395faa-99c1-11dd-bbfe-3dabce05a288
* Implemented TlsVariable, a nifty alternative to __threadlocal, suitable for archaic operating systems that don't have native TLS support (namely Mac OS/X).
* Added a forced reference to TLS in AppInit so that TLS is sure to be available to DLLs (otherwise windows doesn't init TLS by default).
* Disabled TLS support in the x86emitter by default, since it's looking increasingly like we won't find a use for multithreading PS2 sub-components (can be re-enabled later if spontaneous brilliance at a later date proves me wrong).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2396 96395faa-99c1-11dd-bbfe-3dabce05a288
* Optimized codegen of the VPU recompiler using displaced memory offsets (1-2% speedup)
* Undid a lot of the inl stuff for more traditional cpp code layout (explained below)
* Removed some redundant code and turned some macros into functions.
* Renamed a few things to VPU (Vector Processing Unit, which is the specific name of the logic core that performs VIF Command Processing and Unpacking on the PS2)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2387 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added feature to align call targets for EErec functions and blocks on P4's and AMDs, and pack them on Core2/i7's.
* Fixed some svn:native props.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2347 96395faa-99c1-11dd-bbfe-3dabce05a288
* Configuration panels are all modal-less now, so that you can open the config panel and leave it open while running games.
* Handful of thread sync improvements.
* Fixed on-the-fly interpreter/recompiler configuration.
* Fixed plugin hotswapping (mostly works, but still a little funny at times)
* All new assertion dialogs and popup message handlers.
* RecentIsoList defaults to 12 instead of 6
Dev Notes:
* I had to create a new set of assertion functions called pxAssume*. Originally I hoped to avoid that complexity, and just use a single one-assert-fits-all case, but turned out blanketly using __assume() for all assertion cases wasn't reliable.
* wxGuiTools: Replaced the operator, with operator& -- the latter has proper order of precedence, the former required () to scope correctly. >_<

Explanation: EBP was being used by mVU macro-mode (COP2), which violated the new EErec aligned stack setup. ie, register/stack corruption resulted.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2123 96395faa-99c1-11dd-bbfe-3dabce05a288
* Fixed a bug in the Full-mode FPU recompiler.
* Added some better error handling to the BIOS Rom loader.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2117 96395faa-99c1-11dd-bbfe-3dabce05a288
Details:
* Intel's FXSAVE requires an aligned buffer (wasn't explicitly documented in the programmer's guide).
* I moved the wxMenu() objects in the wxApp constructor to OnInit(), which should be post-GTK initialization.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2115 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added SSE_MXCSR union/struct with bitfields and methods for doing common actions.
* Converted all existing MXCSR code to use the new union.
* Added a __pagesize macro for use in conjunction with __pagealigned and dynarec functions.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2113 96395faa-99c1-11dd-bbfe-3dabce05a288
(also includes some header file prepwork for my next wxWidgets windows.h commit fix)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2069 96395faa-99c1-11dd-bbfe-3dabce05a288
* Removed some unused sealed class container mess that liked to cause compilation errors on GCC 4.2
* Added a macro for efficient invocation of static recompiled code buffers.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2065 96395faa-99c1-11dd-bbfe-3dabce05a288
Done:
* EEcore aligns stack on entry and performs routine checks of ESP and EBP integrity.
* Dispatchers are recoded using the PCSX2 Emitter.
Todo:
* Convert all C-code function calls from the recompiler to use the new aligned stack setup.
* Implement stack-alignment checks and emitter-based dispatchers for the IOP.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/aligned_stack@2024 96395faa-99c1-11dd-bbfe-3dabce05a288
* Removed EBP push/pop stuff from the recExecute of the R5900 and R3000A both (not needed anymore since we disabled EBP in iCore).
* Moved the legacy j8ptr and j32ptr buffers to iCore, since they'll go obsolete at the same time iCore does; and nothing outside PCSX2 references them.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2009 96395faa-99c1-11dd-bbfe-3dabce05a288
* Completely new assertion macros: pxAssert, pxAssertMsg, and pxFail, pxAssertDev (both which default to using a message). These replace *all* wxASSERT, DevAssert, and jASSUME varieties of macros. New macros borrow the best of all assertion worlds: MSVCRT, wxASSERT, and AtlAssume. :)
* Rewrote the Console namespace as a structure called IConsoleWriter, and created several varieties of ConsoleWriters for handling different states of log and console availability (should help reduce overhead of console logging nicely).
* More improvements to the PersistentThread model, using safely interlocked "Do*" style callbacks for starting and cleaning up threads.
* Fixed console logs so that they're readable in Win32 notepad again (the log writer adds CRs to naked LFs).
* Added AppInit.cpp -- contains constructor, destructor, OnInit, and command line parsing mess.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1950 96395faa-99c1-11dd-bbfe-3dabce05a288
* handful of minor code cleanups, and some warning removals for ICC.
* replaced the dualshock.png with a dualshock.jpg (120k smaller!)
* Updated the About Box, and added Zeydlitz / ZZogl to the plugin author credits.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1902 96395faa-99c1-11dd-bbfe-3dabce05a288
MemoryCard / Multitap Renovations:
* Memorycards should now support multitap (somewhat untested)
* Implemented a memorycard plugin interface, using the new API defined in PluginCallbacks.h (still prelim and hackish)
* Memorycard settings are saved to ini!
* Multitap is now controlled by PCSX2 instead of the pad plugin (which means no multitap until we implement the gui toggles to enable it)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1817 96395faa-99c1-11dd-bbfe-3dabce05a288
* Fixed a deadlock in thread cancellation.
* Muted some folder warnings when running pcsx2 for the first time.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@1778 96395faa-99c1-11dd-bbfe-3dabce05a288
* Removed NoncopyableObject class and replaced it with a DeclareNoncopyableObject() macro -- which reports saner C++ compilation errors when the object copy is attempted.
* Improved first run wizard and several configuration panels.
* Moved the BIOS selector to its own menu item and dialog box, separate of the Settings panel.
* Fixed various bugs preventing configuration changes from being saved.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/wxgui@1658 96395faa-99c1-11dd-bbfe-3dabce05a288
* Moved the x86 emitter to /common, so that plugins can link against it if they wish.
* Created a new "utility" class in /common which houses string utils, fast memcpy, common exception classes, and other handy dandies.
* Removed old-style linux automake files from the pcsx2 dir since they were hopelessly out of date (and their multi-file-per-line format makes svn merging impossible >_<)
