From f0adc3adb46cb74b71bc2c95d82a4c0662f65d9a Mon Sep 17 00:00:00 2001 From: Marcos Vitali Date: Tue, 8 Feb 2011 01:11:11 +0000 Subject: Speed back to dolpihn: - Revert Read16 CPRead fifo hack for fix RE0. This hack only solve RE0 but brings slowdown in games like RE Umbrella, etc. - Move isFifoBusy again in the fifo loop and use s_fifoIdleEvent for AbortFrame. Note: if you can play RE0 only deactivate PanicAlert. These opdecoding error seems harmless. Some day this wiil be fixed in right way. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7107 8ced0084-cf51-0410-be5f-012b33b47a6e --- Source/Core/VideoCommon/Src/CommandProcessor.cpp | 16 +++++----------- 1 file changed, 5 insertions(+), 11 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 efc0c35ed9..bdafa67fc1 100644 --- a/Source/Core/VideoCommon/Src/CommandProcessor.cpp +++ b/Source/Core/VideoCommon/Src/CommandProcessor.cpp @@ -288,15 +288,15 @@ void Read16(u16& _rReturnValue, const u32 _Address) return; case FIFO_READ_POINTER_LO: - //_rReturnValue = ReadLow (fifo.CPReadPointer); + _rReturnValue = ReadLow (fifo.CPReadPointer); // hack: CPU will always believe fifo is empty and on idle - _rReturnValue = ReadLow (fifo.CPWritePointer); + //_rReturnValue = ReadLow (fifo.CPWritePointer); DEBUG_LOG(COMMANDPROCESSOR, "read FIFO_READ_POINTER_LO : %04x", _rReturnValue); return; case FIFO_READ_POINTER_HI: - //_rReturnValue = ReadHigh(fifo.CPReadPointer); + _rReturnValue = ReadHigh(fifo.CPReadPointer); // hack: CPU will always believe fifo is empty and on idle - _rReturnValue = ReadHigh(fifo.CPWritePointer); + //_rReturnValue = ReadHigh(fifo.CPWritePointer); DEBUG_LOG(COMMANDPROCESSOR, "read FIFO_READ_POINTER_HI : %04x", _rReturnValue); return; @@ -503,11 +503,6 @@ void Write16(const u16 _Value, const u32 _Address) if (!tmpCtrl.ClearFifoUnderflow && tmpCtrl.ClearFifoOverflow) bProcessFifoToLoWatemark = true; - if (tmpCtrl.ClearFifoUnderflow && tmpCtrl.ClearFifoOverflow) - ProcessFifoAllDistance(); - - if (!tmpCtrl.ClearFifoUnderflow && !tmpCtrl.ClearFifoOverflow) - ProcessFifoAllDistance(); } else { @@ -814,8 +809,7 @@ void SetFifoIdleFromVideoPlugin() void AbortFrame() { fifo.bFF_GPReadEnable = false; - while (CommandProcessor::isFifoBusy) - Common::YieldCPU(); + s_fifoIdleEvent.Wait(); GPFifo::ResetGatherPipe(); ResetVideoBuffer(); fifo.CPReadPointer = fifo.CPWritePointer; -- cgit v1.2.3
