From 20eca1bf7e2e02dd18229dc2b6b83935ce0d4047 Mon Sep 17 00:00:00 2001 From: marcosvitali Date: Sun, 18 Mar 2012 22:54:58 -0300 Subject: Ive fixed definitely Pokemon XD in dual core mode. This game is doing something not allowed. It attach to CPU the same fifo attached to the GPU in multibuffer mode. I added a check to prevent overwrite the GPU FIFO with the CPU FIFO. If the game do that on breakpoint the solution can fail. Fixed ReadWriteDistance calc when CPRead > CPWrite. Added Token and Finish cause to GP Jit checking. --- Source/Core/VideoCommon/Src/CommandProcessor.cpp | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'Source/Core/VideoCommon/Src/CommandProcessor.cpp') diff --git a/Source/Core/VideoCommon/Src/CommandProcessor.cpp b/Source/Core/VideoCommon/Src/CommandProcessor.cpp index 3744acd200..a4dddf537f 100644 --- a/Source/Core/VideoCommon/Src/CommandProcessor.cpp +++ b/Source/Core/VideoCommon/Src/CommandProcessor.cpp @@ -61,6 +61,7 @@ volatile bool interruptSet= false; volatile bool interruptWaiting= false; volatile bool interruptTokenWaiting = false; volatile bool interruptFinishWaiting = false; +volatile bool waitingForPEInterruptDisable = false; bool IsOnThread() { @@ -174,7 +175,7 @@ void Read16(u16& _rReturnValue, const u32 _Address) if(fifo.CPWritePointer >= fifo.SafeCPReadPointer) _rReturnValue = ReadLow (fifo.CPWritePointer - fifo.SafeCPReadPointer); else - _rReturnValue = ReadLow (fifo.CPEnd - fifo.CPWritePointer + fifo.SafeCPReadPointer); + _rReturnValue = ReadLow (fifo.CPEnd - fifo.SafeCPReadPointer + fifo.CPWritePointer - fifo.CPBase + 32); else _rReturnValue = ReadLow (fifo.CPReadWriteDistance); DEBUG_LOG(COMMANDPROCESSOR, "read FIFO_RW_DISTANCE_LO : %04x", _rReturnValue); @@ -184,7 +185,7 @@ void Read16(u16& _rReturnValue, const u32 _Address) if(fifo.CPWritePointer >= fifo.SafeCPReadPointer) _rReturnValue = ReadHigh (fifo.CPWritePointer - fifo.SafeCPReadPointer); else - _rReturnValue = ReadHigh (fifo.CPEnd - fifo.CPWritePointer + fifo.SafeCPReadPointer); + _rReturnValue = ReadHigh (fifo.CPEnd - fifo.SafeCPReadPointer + fifo.CPWritePointer - fifo.CPBase + 32); else _rReturnValue = ReadHigh(fifo.CPReadWriteDistance); DEBUG_LOG(COMMANDPROCESSOR, "read FIFO_RW_DISTANCE_HI : %04x", _rReturnValue); @@ -437,11 +438,25 @@ void Write32(const u32 _Data, const u32 _Address) void STACKALIGN GatherPipeBursted() { + ProcessFifoEvents(); // if we aren't linked, we don't care about gather pipe data if (!m_CPCtrlReg.GPLinkEnable) { if (!IsOnThread()) RunGpu(); + else + { + // In multibuffer mode is not allowed write in the same fifo attached to the GPU. + // Fix Pokemon XD in DC mode. + if((ProcessorInterface::Fifo_CPUEnd == fifo.CPEnd) && (ProcessorInterface::Fifo_CPUBase == fifo.CPBase) + && fifo.CPReadWriteDistance > 0) + { + waitingForPEInterruptDisable = true; + ProcessFifoAllDistance(); + waitingForPEInterruptDisable = false; + } + + } return; } -- cgit v1.2.3
