PowerPC IRQ line deassertion; DMA only fires interrupts when required
...
PowerPC no longer clears its own IRQ line; it is now cleared by the IRQ controller when there are no more pending interrupts. Not all games clear DMA interrupts so it was necessary to tweak the 53C810 SCSI controller and the Real3D DMA interface to only fire interrupts if a certain register is correctly set. 53C810 has the documented DIEN (DMA Interrupt Enable) register; Real3D DMA seems to use the low bit of the dmaConfig register.
Also I removed the net IRQ as no games seem to actually use it.

Getting rid of most of the includes from Supermodel.h; each file now explicitly includes the header files it needs.
...
Making changes to a header file should no longer force the entire project to recompile.

Thanks to our anonymous contributor who managed to patch a model 3 game and run it on real h/w, we were able to obtain some timing values we had been long been missing for correct emulation. The h/w polls something called the ping_pong bit at start-up to sync the GPU with the CPU. Unfortunately we didn't have the correct values and just manually used some per game hacks to get games to run. This mostly worked, but some games were writing more or less frames than they should have been for a given time period. When the ping_pong bit flips at 66% of the frame time, games were writing data for a new frame, which meant writes were often straddling 2 separate frames. We aren't 100% sure if IRQ2 or the ping_pong bit is vblank.

- PCI bridge can be specified in Games.xml for games that use a different version than expected based on stepping. No more hard-coded exceptions.
...
- Real3D PCI ID can be specified in Games.xml for exceptions that require it.
- Real3D status bit timing specified in Games.xml for exceptions that require it.

Smooth texture repeat makes no sense for alpha/contour textures with pixel dilate. HW seems to treat them as non smooth anyway. Also implement some line of sight stuff, used by Scud. Really need to check the threading/synchronisation of the register reads but it basically works.

Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle)

- New work-in-progress frame timing code (disabled by default, compile with NEW_FRAME_TIMING defined to activate it)
...
- New JTAG emulation, moved into its own class, CJTAG
- Removed game-specific sun clamp hacks from CNew3D (JTAG and Real3D emulation will call the appropriate method to configure this at run-time)
- Removed JTAG from Real3D save state data and reused some of that space for new state variables having to do with the internal JTAG-based config as well as new frame timing state variables

DMA and register space access for Real3D have been unified and CReal3D::ReadRegister() returns little endian data now that the PowerPC handler byte-swaps back, to be consistent with how DMA registers work.

The mipmap data in some games seems to being sent behind the base textures, and when the base textures are bound and created the mipmap chain is not yet valid in memory. To fix this, we invalidate the base textures, when the mipmap chain is updated.

The model3 has this weird issue where the 2d and 3d planes are misaligned by 2 pixels. Originally I made a quick hack that shifted subviewports 2 pixels. But apparently that wasn't enough, as the issue effects everything. Thanks to HarryTuttle for pointing this out, and making a patch :)

- Committing Nik's timing changes: the PowerPC's DEC and TBR now count at the correct rate and time is accurately maintained between calls to the emulator. A VBlank bit was identified in the Real3D status register space and is now timed. Unfortunately, there are still some problems and not all games are perfect, but FV2, VS2, and others are working much better or perfectly.
...
- Added a new dump of Scud Race Plus (scudp1). Strangely, this one uses an MPC106 instead of the MPC105 used by every other Step 1.5 game...

New multi-threaded rendering changes that parallelise graphics rendering and PPC execution in order to increase performance on multi-core machines.

New gpuMultiThreaded config option to enable/disable multi-threaded rendering (enabled by default, disabling it reverts to previous behaviour).
Other rendering optimisations:
- texture uploads now only affect appropriate region in the texture sheet, rather than uploading the whole sheet each time
- performance of clearing the model caches has been improved
New Alt+O key input added to toggle outputting of frame timings for debugging purposes.
