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".

* 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.

* Moved profiler management to the RecompiledCodeReserve class.
* Improved error handling some more.
* Numerous minor cleanups.

* SuperVU note: SuperVU recompiler now uses two separate 8mb caches for VU0 and VU1 (needed in order to simplify/saneify the reserve/alloc stages of pcsx2 app startup).
* Added MemsetFast.inl, which houses SSE intrinsic versions of memset and memzero, for use on aligned data targets.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/newHostVM@3975 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! :)

DevNotes: DevCon logs are now available in *Release* builds as well as Devel builds, and can be enabled from the Console window's "Sources" menu. They are disabled by default in Release builds, and are always enabled regardless of the ini setting in devel builds. Debug logs are still strictly available in debug builds only.

I also re-implemented R5900 runtime exception handling for TLB Miss and such (devbuilds only, for now).

* renamed PersistentThread to pxThread (shorter, sweeter, and the 'persistent' part is obsolete since its now a full blown thread manager since some while ago).
* Renamed a bunch of the PostMethodToMain stuff to Rpc_TryInvoke* (for remote procedure call). It's probably not a good use of the term, but I'm bummed I can't think of anything better/shorter.

* ConsoleLogger Optimization: Improved performance considerably for when the log gets spammed by EEcore or MTGS threads.
DevNotes:
* Added a new pxYieldToMain() method (currently implemented in Win32 only). It provides a smart way to allow passive-task worker threads to yield time to the Main Thread when important messages are pending (keyboard or mouse clicks, primarily). It also replaces the wxGetApp().Ping() stuff, which never worked anyway due to wxCommandEvents having a higher priority than native system messages.

* 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.

Rationale: FromAscii should only be used on old-style DOS/ANSI character strings that use the upper 128 characters for drawing pictures or writing umlauts, which is pretty much nothing at all as far as PCSX2 is concerned. Chances are even the japanese console logs coming from the PS2 itself use UTF8.

* Added timeBeginPeriod() to improve the Win32 kernel scheduler resolution (improves sleep accuracy and thread responsiveness)
* hackfixed some code that made exiting pcsx2 "slow" sometimes.

* Fixed and added better Emulation/System menu updating. Suspend/Resume is more consistent, and Reset grays itself out after being used.
* Entering plugin configurations auto-suspends the emulator.
* Changing plugins in the Configuration PAnel takes effect now without a restart.
* Added preliminary support for an ExtensibleConfirmation Dialog box (contains a sizer you can add content to, and also has an optional "[x] Do not show this again" checkbox).
Bugfixes:
* Added some mutex protection to cdvdNewDiskCB; "just in case."
* Resolved several recursion and deadlock scenarios when (very!) rapidly suspending, resuming, and resetting the emu.
Developments / Code Cleanups:
* Renamed SysCoreThread ExecutionModes: Suspend/Resume are now Opened/Closed (which more accurately reflects the fact they opena nd close the plugins, and helps avoid ambiguity with the "Paused" state).
* Added Exception::ThreadTimedOut, which is now thrown from Semaphore::Wait when recursive wxApp::Yield() calls are detected, and a deadlock occurs (basically cancels the current action which, most of the time, allows for full recovery).
* Major Threading namespace cleanups, documentations, etc.
* Removed wxScopedArray (scopedarray.h) and replaced it with a better implemeneted ScopedArray class.
* Removed toUTF8 class, which I only added a couple weeks ago because I didn't realize wxCharBuffer had an implicit typecast to (char*).
* Implemented more Source/Listener events for Pcsx2App. CoreThread events are sourced properly now, and added SettingsApplied and SettingsLoadSave Sources.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2010 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.

Note: Nearly have a successfully booting branch! (bios crashes when it reaches CDVD api callbacks, should be a simple fix but it'll have to wait until later >_<)

* Major cleanups and improvements to the Threading namespace.
* Created CoreEmuThread class framework, which currently runs the EEcore, IOP, and VUs with threadsafe suspension, reset, and resume features.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/wxgui@1624 96395faa-99c1-11dd-bbfe-3dabce05a288
* Implemented internationalization (i18n) framework.
* Made a pretty configuration dialog box!
* Many minor bugfixes.
* Removed most of the old Win32 and Linux/GTK gui code because it was causing gettext cataloging to grab about 500 non-relevant strings (can always reference trunk for them anyway).
git-svn-id: http://pcsx2.googlecode.com/svn/branches/wxgui@1484 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 >_<)
