- Improved the GP Register Status: now this is all the time from the fifo loop.
- Improved the Interrupts manage:
1) Removed All UpdateInturrupts from CommandProcessor Writes and Read.
2) now the CP interrupts are schedule from the video thread and the fifo loop waiting until this happens
3) considering Inmediate mode for the CP interrupts
3) Implemented Interrupt CP Cache State
4) Implemented only Overflow interrupt in GatherPipeCheck because this need to be detected quickly.
- Implemented Overflow handling like a real HW, when Hiwatermark interrupt happens this write ClearRegister with True en HI and False in LO (FifoIntReset) after that a Control Register is writed and the FIFO is processed to LO Watermark.
- Removed all ugly code from LO and HI watermark manage
- Removed all ugly code from BP manage
- Change >= by == in the BP clauses
- Removed speed hack (1024 chunk) for better GP Status Control.
- Commented GXSetGPFifo very soon hack
- Commented FackWatchDog hack
- Commented FIFO_RW_DISTANCE = WritePointer hack
This is the beginning and the base for the future., If this broke your favorite game my apologize, only report this and will try solve it. If you have a Overflown don't worry, I've implemented the real solution code using the Overflow Interruption only need continue working for a perfect protection. Why I did it? Because is preferable a accurate and clean fifo instead hack y fifo for improve that. Thanks to DONKO for you awesome Video Plug in and skid for the chatting. PD: I have 7-10 fps more in the star fox video. bye :P

* I've fixed concurrency problem with fifo.bFF_GPReadEnable when the breakpoint is achieved
* I modified when fifo.bFF_Breakpoint is turn off to prevent that the interruption happens
* I reverted r6483
* I improved the commit r6495 adding another protection when the GPRead is enabled in CTRL_REGISTER
You can test Pokemon XD in dual core mode is more estable now :P This commit could solve others hangs fifo related in DKC, Sport Resorts, etc. I dont have these games.

Plus: I added a _assert_msg_ in FIFO loop when the WriteDistance is negative. Please if that happens report it, this can help to solve strange issues with wrong WriteDistances.

In this way it prevents wrong fifo.CPReadWriteDistance in the future. That should fix RE0 Issue 2846 and others "Warning: GFX FIFO: Unknown Opcode (0x4d)" in dual core mode.

Really that happens because the fifo.CPReadWriteDistance is negative.
Example: CPReadWriteDistance: -864 CPEnd: 10092672 fifo.CPBase: 9568416
In SMG this is because PI_FIFO_RESET is writing and after fifo.CPReadWriteDistance will be setted to 0.
To Prevent that, I've Implemented AbortFrame function in the CommmandProcessor. It should fix overflown because of that.
Note: There is other issue (Issue 2846) where the fifo.CPReadWriteDistance is negative too but the effect is different.
I'm working to solve this.

This is EXPERIMENTAL, in theory don't break any game but if so Revert this commit immediately please.
Note: Beside Eternal Darkness needs DirectX 11 or DirectX 9 with Zelda Hack to works fine.

Dual Core sync fix.
When the FIFO is processing data we must not advance the cpu cycles in CoreTiming because in this way the VI will be desynchronized. So, We are waiting until the FIFO finish and while we process only the events required by the FIFO.
This should fix Issue 2072 .
This affect to all games in dual core mode.
Please, You can test all games with VPS limiter auto, 60, 50 depending of the game and compare with prev revision.
For example now NSMB in the video Intro has 60 fps (prev 30 fps) :D or SMG does't need anymore FPS Limitter Hack to get 55-60 fps
Beside the slowdowns now are more softly and the fps more stables because the VI sync is almost perfect.
The Core Timing and Fifo modifications are delicated. Please report if this hang any game. Don't forget check with prev revision.
Enjoy it! Thanks to Rodolfo for teach me all about dolphin.
