Baten Kaitos allocates its XFBs from a tagged heap
structure. With the old calculation, too many lines
were being written so the tag of the allocation
after the XFB was being corrupted. Fixes crash

Samsung updated the video drivers on the SGS6 which introduced a bug when disabling vsync.
Both the driver versions are r5p0, but the md5sums of the blob differ.
To work around the issue, make sure to never disable vsync by calling eglSwapInterval.
We can't actually determine the driver version on Android yet.
So until the driver version lands that displays the driver version string in the GL_VERSION string
we will need to keep this workaround enabled at all times, which is a bit annoying.
Current mali drivers return the video driver version in one of the EGL strings you can query.
The issue with that is that Android eats all of those strings, so we can't query it.
Their new driver that supports GLES3.1 + AEP has issues with it.
At the very least they don't implement all of the geometry shader features fully which causes shader linker issues when we attempt to use them.
I don't have a device so I can't fully test, so until I do I'm going to blanket disable the whole thing.
The Star Wars games really push the hardware to its limits, which can cause the shaders that are produced to be 18kb or more.
Double our maximum shader size to compensate.
Fixes issue #8860
The last heuristic wasn't quite smart enough and had a few
false positives in Mario Kart: Double Dash and Metroid prime 2.
Now we only activate if the game is rendering a 16:9
projection to a 4:3 viewport.
Someone suggested on IRC that we should make a database of memory
locations in GameCube games which contain the 'Widescreen' setting
so we can automatically detect if the game is in 4:3 or 16:9 mode.
But that's hardly optimal, when the game actually tells the gpu
what aspect ratio to render in. 10 min and 6 lines of code later,
this is the result. Not only does it detect the correct aspect ratio
it does so on the fly.
I'm a little suprised nobody thought about doing this before.
When calculating the size of the undisplayed margin in the case where
fbWidth != fbStride for RealXFB for displaying in the output window,
we do not scale by IR - RealXFB is implicitly 1x.
This bug has been reported to IMGTec at https://pvrsupport.imgtec.com/ticket/472
The basic idea of the bug is that if you're doing a bitwise and of a constant value vector with a constant scalar value, this causes PowerVR's shader
compiler to fail out with a very non-descriptive message.
Working around the issue by making the value a vector that it is being masked by.
In particular this fixes the 6666 colour format
We were loading from the wrong location and it was causing /terrible/ colour changes.
This also fixes a bug in the all the colour formats(except 888) where the unaligned path was loading in to the wrong register.
- Fixes remaining lighting issues (Mario Tennis, etc)
- Apply same fixes to Software Renderer
- Corrected zero length light direction vector to resolve with normal direction (essentially becomes LIGHTDIF_NONE which was what I was after)
The new implementation has 3 options:
SyncGpuMaxDistance
SyncGpuMinDistance
SyncGpuOverclock
The MaxDistance controlls how many CPU cycles the CPU is allowed to be in front
of the GPU. Too low values will slow down extremly, too high values are as
unsynchronized and half of the games will crash.
The -MinDistance (negative) set how many cycles the GPU is allowed to be in
front of the CPU. As we are used to emulate an infinitiv fast GPU, this may be
set to any high (negative) number.
The last parameter is to hack a faster (>1.0) or slower(<1.0) GPU. As we don't
emulate GPU timing very well (eg skip the timings of the pixel stage completely),
an overclock factor of ~0.5 is often much more accurate than 1.0
This fixes issue 6563:
https://code.google.com/p/dolphin-emu/issues/detail?id=6563
This PR adds a 2nd map to texture cache, which uses the hash as key. Cache entries from this new map are used only if the address matches or if the texture was fully hashed. This restriction avoids false positive cache hits. This results in a possible situation where safe texture cache accuracy could be faster than the fast one.
Small textures means up to 1KB for fast texture cache accuracy, 4KB for medium, and all textures for safe accuracy.
Since this adds a small overhead to all texture cache handling, some regression testing would be nice. Games, which use a lot of textures the same time, should be affected the most.
I tried to change messages that contained instructions for users,
while avoiding messages that are so technical that most users
wouldn't understand them even if they were in the right language.
Address static memory relative to a base register, analog to what we're
doing with PPCSTATE in the CPU JIT. This allows executable memory for
the vertex loader JIT to be allocated anywhere, not just within 2 GiB of
static data.
Fixes issue 8180.
