With all of the interfaces ready for migration, it's trivial to migrate
over GetPointer().
|
|
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.
Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.

gl_device: Deduce indexing bug from device instead of heuristic
|
|
Casts from f32 to f16 zeroes the higher half of the target register.
|
|
The heuristic to detect AMD's driver was not working properly since it
also included Intel. Instead of using heuristics to detect it, compare
the GL_VENDOR string.

|
gl_texture_cache: Apply sRGB on blits
|
|
gl_shader_cache: Miscellaneous changes to shaders
|
|
glBlitFramebuffer keeps in mind GL_FRAMEBUFFER_SRGB's state. Enable this
depending on the target surface pixel format.
|
|
gl_shader_gen: Apply default value to gl_Position
|
|
SSBOs and other resources are limited per pipeline on Intel and AMD.
Heuristically reserve resources per stage having in mind the reported
OpenGL limits.
|
|
glBindTextureUnit doesn't support null textures. Skip binding these.
|
|
Intel's proprietary driver enters in a corrupt state when compute
shaders are executed. For now, disable these.
|
|
The current shared memory size seems to be smaller than what the game
actually uses. This makes Nvidia's driver consistently blow up; in the
case of FE3H it made it explode on Qt's SwapBuffers while SDL2 worked
just fine. For now keep this hack since it's still progress over the
previous hardcoded shared memory size.
|
|
|
|
Stage and compute shaders were using a different binding counter.
Normalize these.
|
|
|
|
|
|
|
|
Images were not being bound to draw invocations because these would
require a cache invalidation.
|
|
Local memory size in compute shaders was stubbed with an arbitary size.
This commit specializes local memory size from guest GPU parameters.
|
|
Shared memory was being declared with an undefined size. Specialize from
guest GPU parameters the compute shader's shared memory size.
|
|
Drop the usage of ARB_compute_variable_group_size and specialize compute
shaders instead. This permits compute to run on AMD and Intel
proprietary drivers.
|
|
Instead of specializing shaders to separate texture buffers from 1D
textures, use the locker to deduce them while they are being decoded.
|
|
Nvidia has sane default output values for varyings, but the other
vendors don't apply these. To properly emulate this we would have to
analyze the shader header. For the time being, apply the same default
Nvidia applies so we get the same behaviour on non-Nvidia drivers.

texture_cache: Use a flat table instead of switch for texture format lookups
|
|
gl_rasterizer: Emulate viewport flipping with ARB_clip_control
|
|
Abstracted ComponentType was not being used in a meaningful way.
This commit drops its usage.
There is one place where it was being used to test compatibility between
two cached surfaces, but this one is implied in the pixel format.
Removing the component type test doesn't change the behaviour.

shader: Implement FSWZADD and reimplement SHFL

video_core: Treat implicit conversions as errors

GLSLDecompiler: Correct Texture Gather Offset.
|

Properly pass engine when a shader is being constructed from memory.

Silence GLSL compilation warnings.

This commit corrects the argument ordering in textureGatherOffset.
|
|
|
|
|
|
|
|
Emulates negative y viewports with ARB_clip_control. This allows us to
more easily emulated pipelines with tessellation and/or geometry shader
stages. It also avoids corrupting games with transform feedbacks and
negative viewports (gl_Position.y was being modified).

gl_rasterizer: Upload constant buffers with glNamedBufferSubData
|
|
shader/node: Unpack bindless texture encoding
|
|
Global memory is still using the stream buffer when it shouldn't. As a
temporary fix re-enable the stream buffer on compute.
|
|
Nvidia's OpenGL driver maps gl(Named)BufferSubData with some requirements
to a fast. This path has an extra memcpy but updates the buffer without
orphaning or waiting for previous calls. It can be seen as a better
model for "push constants" that can upload a whole UBO instead of 256
bytes.
This path has some requirements established here:
http://on-demand.gputechconf.com/gtc/2014/presentations/S4379-opengl-44-scene-rendering-techniques.pdf#page=24
Instead of using the stream buffer, this commits moves constant buffers
uploads to calls of glNamedBufferSubData and from my testing it brings a
performance improvement. This is disabled when the vendor is not Nvidia
since it brings performance regressions.

This requires removing constness from some methods, but for consistency
it's removed in all methods.
