skidau 83fc5f4747 Merge branch 'FIFO-BP'
# By skidau (30) and Pierre Bourdon (1)
* FIFO-BP: (31 commits)
  Set g_bSignalTokenInterrupt on the main thread.  Fixes the random hang in Harry Potter: Prisoner of Azkaban.
  Used a scheduled event to generate the ARAM DMA interrupt if the DMA is greater than a certain size.  Fixes NFS:HP2 GC.
  Bumped up the disc transfer speed enough to prevent audio stuttering in Gauntlet: Dark Legacy.
  Enabled Synchronise GPU on "SPEED CHALLENGE - Jacques Villeneuve's Racing Vision".  Required to go in-game.
  Added direct GameCube controller commands to the Serial Interface emulation.  Fixes the controls in MaxPlay Classic Games Volume 1 and the Action Replay disc.
  Increased the FIFO buffer size to 2MB from 1MB.  Fixes Killer 7's Angel boss.
  Used an immediate GenerateDSPInterrupt when transferring data from ARAM to MRAM and a scheduled DSP interrupt when transferring data from MRAM to ARAM.
  Fixes the audio cutting in and out in the Resident Evil GC games using DSP HLE. Triggered the ARAM interrupt by the scheduler instead of directly in function.
  Implemented proper timing for the sample counter in the AudioInterface, removing the previous hack. Cleaned up some of the audio streaming code.
  Skipped the EE check if there is a CP interrupt pending.
  Disabled "Speed up disc transfer" from the ZTP GC game ini.
  Removed the disc seek times for GC games and removed the disc speed option on Wii games. Checked for external exceptions only in mtmsr.
  Delayed the interrupts in the EXI Channel.
  Merge aram-dma-fixes (r76a13604ef49b522281af75675f044d59a74e871)
  Added a patch that bypasses the FIFO reset code in Wallace and Gromit: Project Zoo, allowing it to go in-game.
  Made vertex loading take constant time.
  Increased the cycle time of the vertex command.  Fixes "Speed Challenge: Jacques Villeneuve's Racing Vision".
  Moved the setting of the Finish interrupt signal back to the main thread as it was causing Wii games like Resident Evil 4 (Wii) to hang.
  Profile stores, fp stores and ps stores only to the fifo write addresses list.  This should make the JIT a little faster as it will not be checking for external exceptions unnecessarily.

NeoBrainX 008fdc7310 Merge branch 'perfqueries'.
Adds support for PE performance metrics.
Used in Super Mario Sunshine's "Scrubbing Sirena Beach" level to determine when enough goop has been cleaned up to finish the level.
Also used in TimeSplitters: Future Perfect to determine the appearance of flares around light sources (e.g. sun).

OpenGL and D3D11 only. D3D9 support unlikely to be added unless anyone bothers to do the work.
Initial work and D3D11 support by me. Kudos go to Billiard for adding the OpenGL support and reviving development of this branch that way :D

Slightly (~7%) decreases performance when performance metrics are used (and only then).

Fixes issue 1498.
Fixes issue 5368.

* master: (70 commits)
  Fixes two memory leaks, one is pretty bad for OSX. Yell at pauldachz if this doesn't work. Or... say thanks.
  Added a BluetoothEnumerateInstalledServices call so that the wiimote remembers the pairing.
  Make ARMJit core default CPU core on ARM architecture
  Fix a StringUtil regression from the arm-noglsl merge
  Small improvement to cmpli/cmpi in ARMJit.
  Merge latest ArmEmitter changes from ppsspp while we're at it.
  Ah. I blame vim on this typo entirely.
  Add disabled code for authenticating wiimotes on Windows.
  Add the missing FPR cache
  Buildfix.
  Yell at the user if they change window size while dumping frames, and some other avi dumping stuff.
  Not sure if this is the right way to handle this, but it makes the save states perfectly stable. That's all that really matters, right?
  Abort loading states from incompatible graphics backends.
  ARM Support without GLSL
  Improve VideoSoftware save states. They are fairly stable, but not perfect. OpcodeDecoder::DoState() needs to be fixed.
  Begin implementing save states to video software. Kind of works, sometimes.
  Make error message for loading save state with wrong dsp engine shorter.
  Abort load state if it uses a different dsp engine, instead of crashing.
  Update the gameini of F-zero. Efb to Ram is no longer the default choice.

# By Jordan Woyak (9) and others
* master:
  Fixed a buffer overflow in the OpenAL buffer.
  TextureCache: Fix D3D backends crashing when a game uses multiple 1x1-sized LODs.
  WII_IPC_HLE_Device_FileIO: don't rebuild the filename on every operation.
  Some cleanup of CWII_IPC_HLE_Device_FileIO: The real file was never kept open for longer than a single operation so there was no point in dealing with it in DoState. Saving the real path in the savestate was also probably a bad idea. Savestates should be a bit more portable now.
  Removing destination on rename when source isn't present doesn't make sense. IOCTL_RENAME_FILE still might not be totally correct.
  Change some CNANDContentLoader logic to what was probably intended. Kills some warn logs when opening Dolphin.
  Let's not CreateDir an empty string every time CreateFullPath is used, logging an error every time.
  Fix a memleak. Probably/maybe improve USBGecko performance.
  Remove the core count from the cpu info OSD message. It was often wrong and not rather important.
  Use omp_get_num_procs to set the number of OpenMP threads rather than our core count detection.
  Bulk send TCP data to the client with the emulated USB Gecko.
  Added the ability to reverse the direction of the force feedback by allowing negative range values.
  Changes/cleanup to TextureCache::Load and other mipmap related code. The significant change is what is now line 520 of TextureCacheBase.cpp: ((std::max(mipWidth, bsw) * std::max(mipHeight, bsh) * bsdepth) >> 1) to TexDecoder_GetTextureSizeInBytes(expanded_mip_width, expanded_mip_height, texformat);
