For whatever reason, the hardware doesn't do a full divide by 255, but
instead uses an approximation with shifting, similar to the way it is done
in TEV.
For quite a while this has been causing integer division to generate a warning as error, blocking shader compiling. This means probably no one has even been running D3D in debug builds...
I tried disabling the warning with a #pragma, but it doesn't seem to apply when this flag is used.
We need to pull in function pointers for OpenGL 3.0 in order to use glAttribIPointer.
This isn't too big of an issue, and this code will be gone in the future when we change over to libepoxy.
Just need to push code upstream to libepoxy to support Android with GLES and GL first.
This matches how ARM handles their naming in their drivers for different models.
Really it's that way because both Mali-T6xx and Mali-T7xx fall under Midgard.
While everything else (except Mali-55) fall under Utgard.
We need to explicitly round when converting colors from float to uint
because multiplying a normalized float by 255 might not result in a whole
number. (The exact result here may vary depending on your
drivers/hardware.)
Ideally, we shouldn't be using floating point here, but fixing that is a
much more complicated patch.
Fixes gxtest TEV tests using Intel HD 4000.
They are similar enough that they will share bugs with their drivers, so make them fall under the same Mali-Txxx umbrella of bug issues.
If there is ever a need in the future for having separate bugs depending on family, we can support that then.
This is the only way we can determine the video driver version with mali.
Really it's a good thing that they only push driver updates once every two years, makes it easy to determine what driver anybody is running.
CreateInputLayout requires a shader as an input, but it only cares about
the signature; we don't need to recompute it for different shaders with
the same inputs.
GLSL ES 3.10 adds implicit support for the binding layout qualifier that we use.
Changes our GLSL version enums to bit values so we can check for both ES versions easily.
Trying to use GetDepthMatrixProgram outside of
TCacheEntry::FromRenderTarget is a bad idea, so don't. Instead, use a
shader which only copies the input.
