This allows rendering to 3D textures with more than one slice.
Applications are allowed to render to more than one slice of a texture
using gl_Layer from a VTG shader.
This also requires reworking how 3D texture collisions are handled, for
now, this commit allows rendering to slices but not to miplevels. When a
render target attempts to write to a mipmap, we fallback to the previous
implementation (copying or flushing as needed).
- Fixes color correction 3D textures on UE4 games (rainbow effects).
- Allows Xenoblade games to render to 3D textures directly.
Implement more surface reconstruct cases. Allow overlaps with more than
one layer and mipmap and copies all of them to the new texture.
- Fixes textures moving around objects on Xenoblade games
This reverts commit 94b0e2e5da.
preserve_contents proved to be a meaningful optimization. This commit
reintroduces it but properly implemented on OpenGL.
We have to make sure the clear removes all the previous contents of the
image.
It's not currently implemented on Vulkan because we can do smart things
there that's preferred to be introduced in a separate commit.
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.
We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).
While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.
This is a simple optimization as Buffer Copies are mostly used for texture recycling. They are, however, useful when games abuse undefined behavior but most 3D APIs forbid it.
preserve_contents was always true. We can't assume we don't have to
preserve clears because scissored and color masked clears exist.
This removes preserve_contents and assumes it as true at all times.
Some games bind incompatible texture types to certain types.
For example Astral Chain binds a 2D texture with 1 layer (non-array) to
a cubemap slot (that's how it's used in the shader). After testing this
in hardware, the expected "undefined behavior" is to report all pixels
as black.
We already have a path for reporting black textures in the texture
cache. When textures types are incompatible, this commit binds these
kind of textures. This is done on the API agnostic texture cache so no
extra code has to be inserted on OpenGL or Vulkan.
As a side effect, this fixes invalidations of ASTC textures on Astral
Chain. This happened because yuzu detected a cube texture and forced
6 faces, generating a texture larger than what the TIC reported.
Layered framebuffer attachments is a feature that allows applications to
write attach layered textures to a single attachment. What layer the
fragments are written to is decided from the shader using gl_Layer.
This commit adds a series of HLE methods for handling 3D textures in
general. This helps games that generate 3D textures on every frame and
may reduce loading times for certain games.
This commit aims to redo the full setup of invalid textures and
guarantee correct behavior across backends in the case of finding one by
using black dummy textures that match the target of the expected
texture.
Use a large flat array to look up texture formats. This allows us to
properly implement formats with different component types. It should
also be faster.
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.
Amends the doxygen comments so that they properly resolve. While we're
at it, we can correct some typos and fix up some of the comments'
formatting in order to make them slightly nicer to read.
