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).

* 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.

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.
