Since we have been employing the FIFO BP hack for so long time, at least let's make it a decent hack. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@4699 8ced0084-cf51-0410-be5f-012b33b47a6e

BIG FIFO Commit PART 1! Sometimes you need to write everything from 0, so 10 days later Ive rewrited some parts of the FIFO in Dual Core mode. Is pending use the same code for SC mode. - 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 git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6554 8ced0084-cf51-0410-be5f-012b33b47a6e

made savestates synchronous and immediate. this allows saving or loading while the emulator is paused, fixes issues where savestate hotkeys would get ignored if pressed too close together, might speed up savestates in some cases, and hopefully makes savestates more stable too. the intent is to replace the haphazard scheduling and finger-crossing associated with saving/loading with the correct and minimal necessary wait for each thread to reach a known safe location before commencing the savestate operation, and for any already-paused components to not need to be resumed to do so.

Big Fifo Commit Part2: Now the fifo is more stable than my first commit, so is time... - ReImplementing Single Core Mode like Dual Core Mode Style. - Stage 1: My goal is, we have the Fifo, CommandProccessor code the more clear, maintenible and documented possible. When I quit dolphin I want any developer can continue with the work only reading the code. * Big Refactoring: A lot of functions was changed the names, and modularized. Now the FifoLoop and CatchUpGPU does not exist, was replaced by RunGpu() and RunGpuLoop(). The general idea is modeling the code like the real HW. The fifo is only a buffer where the Write Gather Pipe write the commands and from the Graphic Processor read these. * Big Clean UP a lot of obsolete code and comments was deleted, like DcFakeWachDog, "Fifo very soon hack", etc. In the stage 2, I will refactoring more code doing emphasis in the division of CommandProcessor, Fifo, Gpu Emulation. Beside I will comment all functions and variables in the code (Don't worry I will ask for English help for this part ;) ) Please test a lot SC mode and DC mode :) Thank you so much for testing always and the patience. I don't like broke your favorite game but... you must believe me this part is very sensible, I only try to contribute for have a better and stable dolphin emulator. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7185 8ced0084-cf51-0410-be5f-012b33b47a6e

The Mega Change Of Doom - or, fixing Stop. Almost. At least it's better than before. However, the OpenGL plugin seems to lose textures a lot between game restarts :P I think the GL plugin needs to do a lot more cleanup. This change also includes tons of minor code formatting cleanup. Yeah, should've separated it ... sorry :( Kills the old CPUCompare support. I'll resurrect it if I need it again, right now it mostly clutters the code. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@2321 8ced0084-cf51-0410-be5f-012b33b47a6e
