Everblue: Slightly messy fix, not as nice as id hope, but it seems to work, we need to remember VU programs written to the VU so we can check if an unpack is modifying it. This retains the behaviour of the Snowblind engines whilst fixing everblue.
Hitman 2: Our vif0/1VUFinish() routing which works in conjunction with the delays wasn't paying attention to if the VIF was stalled or not and reran it before the game wanted it to, now fixed.

Path3 Masking: Fixed a bug which caused persona 3 not to boot, previous a hack had been put in place to get around this.
VIF: Fixed a VIF error with the rare game Realta Nua, now goes through the prologue correctly. Game requires the EE timing hack to get rid of most of the noise (Path3 masking problem with new GIF unit, unfixable).
Expecting bugs, I will be monitoring this.

Also added a couple important global variables to be savestated (breaks old state compat).

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".

some bits were kept for reference and should be deleted in the future (along with the entire GIFpath.cpp)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4823 96395faa-99c1-11dd-bbfe-3dabce05a288
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.

For future reference:
Clearing registers on VIF reset = bad! That operation is designed to stop VIF Processing its current data, nothing more.
More importantly it causes me a great headache as it took me 2 days to find this >.<
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4519 96395faa-99c1-11dd-bbfe-3dabce05a288
Cleaned up Gifdma a little, removing duplicate code. Disabled a few console writes we dont nee really.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4278 96395faa-99c1-11dd-bbfe-3dabce05a288
* All remaining code for handling partial/fragmented unpacks removed.
* vifRegs.NUM is now accurately simulated when queuing data from fragmented unpacks.
* Reduced the VIFunpack fragment buffer from 1MB to 4KB (max size of an unpack due to NUM being limited to 8 bits).
* Removed vif/vifRegs globals formally used by VIF interpreters (everything relies on the templated vifIdx now -- simpler and faster!)
* g_vifMask vars are integrated into vifStruct.
* All VIF mask register stuff uses the SSE-friendly vifStruct.MaskRow/Col vars now.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3762 96395faa-99c1-11dd-bbfe-3dabce05a288
* Writes via 16 and 8 bit ops now use 32-bit read/modify/write operations by default; which should enable nearly complete support for all such operations (instead of the formerly spotty coverage before).
* Eliminated almost all former 8/16-bit specific register operations. All code shares the same 32 bit handlers now.
* Completely revamped the developer trace logs for hardware registers! *ALL* registers are logged now, complete with address, name, and value being read/written (and nicely formatted!).
* Handlers are now fully page-based using templated functions (minor speedup)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3704 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! :)

Games
- Resident Evil Dead Aim flickering graphics fixed.
- Flatout games should now boot everytime (instead of randomly)
- Sega Superstar Tennis flashing fixed
- Destruction Derby graphics fixed (NTSC confirmed, PAL unsure)
- Tenchu Fatal Shadows flickering textures fixed, Issue 748
- Spyro Hero's Tail should boot again, Issue 746
General Info
- General reworking of the GS paths with all paths prioritizing more correctly.
- XGKICK can stall if another GS transfer is in progress
- Major reworking of Path3 masking, could still be combined with normal Path3 transfers, but lets get it working first :P
- Taken in to account a few conditions which could have caused VIF to lock up/crash when stalling on ends.
- Unreversed GIF and SPR and VIF so its the normal way round
- all DMA paths should now resume correctly after being stopped by hardware
- GIF FIFO now actually transfers stuff :P
- VIF CMD's simulated by the length of the interrupts at the end.
Phew, i think that's everything :S
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3274 96395faa-99c1-11dd-bbfe-3dabce05a288
Also clean-up/fix of GS download logic. Might fix something if we're very lucky.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2954 96395faa-99c1-11dd-bbfe-3dabce05a288
-Improved DMA Queuing slightly, less "all over the place" code.
-Jiggled some IPU bits around to clean up some clutter.
-Added the FFX and Digital Devil Saga video fixes as a Gamefix for now. Due to the delay involved, this causes other videos to terminate early, so now disabled by default.
-Added a load of logging for hardware in dev builds (also now label more correctly) and some bits for debugging IPU easier. Some are commented out, but can be enabled for testing.
-Made a small clarification in VIF
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2875 96395faa-99c1-11dd-bbfe-3dabce05a288
- BIOS works again, Issue involving GIF Tag looping from the VU (which must have never worked!)
- Fixed KH freeze issue, possibly fixes Onimusha 2 as well. Thx Arcum for spotting it, thanks Rama for trying to bring fast resolution to the issue (however it wasnt quite right)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2856 96395faa-99c1-11dd-bbfe-3dabce05a288
- Improved handling of suspended DMA's, Also some traps in case DMA values are changed during suspend (please report if they don't start with 5 or 6)
- Better handling of GS Path priorities, this improves many Path3 Masked games such as Star Wars Episode 3, Gran Turismo 4 (slightly) and Videos like Digital Devil Saga/FFX
- Removed Voodoo Cycles
- Doesn't kill everything this time :P
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2853 96395faa-99c1-11dd-bbfe-3dabce05a288
So this reverts all VIF and GIF related code of that revision,
leaving only the changes that were made to IPU.
Compatibility should be fixed again, with the added bonus of lots more videos working.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2828 96395faa-99c1-11dd-bbfe-3dabce05a288
- IPU 1 DMA rewritten - now much more readable, less hacky. A couple of games are still slightly picky, but overall compatability is similar (if not better in some cases)
- Reverse VIF transfers figured out and implemented (mostly)! - There are still some problems with this, will work on it.
- Improved GS PATH transfer control, now PATH2 and 3 cant transfer when PATH1 is, PATH3 cant when PATH2 is and so on.
- IPU now waits for ended GS transfers, for some reason this was screwing videos (mainly from PATH2) and causing them to be torn, which the original voodoo cycles addition fixed.
Note: You may see a lot of "Double IRQ on DMA 4" messages. At the moment these are unavoidable but aren't actually causing any issues. I do know about them :P
Feel free to negative is I've seriously broke something lol
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2822 96395faa-99c1-11dd-bbfe-3dabce05a288
-Rewrote VIF0 DMA to work like VIF1, report any breakage from it.
-Tweaked a couple of cycle bits when stalling VIF

Not in effect yet cuz there seems to be a minor bug in the current saved-state versioning system. (GetVersion() is not correctly returning the loaded-state's version when loading a saved state)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2567 96395faa-99c1-11dd-bbfe-3dabce05a288
There is a lot of code duplication in the vif0/vif1 files, I will probably work on getting them to use common functions.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2489 96395faa-99c1-11dd-bbfe-3dabce05a288
Notes to Devs:
- Linux project files probably need to be updated since I deleted some files.
- In the vif0/vif1 Freeze() functions for saved states, I kept some dummy vars to keep saved state compatibility. We should remove them next time we decide to break saved state compatibility.
