When the dynamic state is specified, pViewports and pScissors are
ignored, quoting the specification:
pViewports is a pointer to an array of VkViewport structures, defining
the viewport transforms. If the viewport state is dynamic, this member
is ignored.
That said, AMD's proprietary driver itself seem to read it regardless of
what the specification says.
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.
This reverts commit 05cf270836.
Apparently the first approach using floats instead of bitfieldInert
worked better for Fire Emblem: Three Houses. Reverting to get that
behavior back.
From my testing on a Splatoon 2 shader that takes 3800ms on average to
compile changing to FullDecompile reduces it to 900ms on average.
The shader decoder will automatically fallback to a more naive method if
it can't use full decompile.
Makes popup texts more compact and clear and also links our quickstart guide now.
Also removes OnMenuSelectEmulatedDirectory from the File dropdown, as the action already exists in the Filesystem tab and provides better visual feedback there.
The base level is already included in the texture view. If we specify
the base level in the texture again, this will end up in the incorrect
level and potentially out of bounds.
This also fixes Turing issues but it avoids doing more bitcasts. This
should improve the generated code while also avoiding more points where
compilers can flush floats.
Implements the common usages for VMNMX. Inputs with a different size
than 32 bits are not supported and sign mismatches aren't supported
either.
VMNMX works as follows:
It grabs Ra and Rb and applies a maximum/minimum on them (this is
defined by .MX), having in mind the input sign. This result can then be
saturated. After the intermediate result is calculated, it applies
another operation on it using Rc. These operations are merges,
accumulations or another min/max pass.
This instruction allows to implement with a more flexible approach GCN's
min3 and max3 instructions (for instance).
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.
This corrects the behavior of free buffer after witnessing it in an
unrelated hardware test. I haven't found any games affected by it but in
name of better accuracy we'll correct such behavior.
Since commit e22816a5bb we handle type mismatches from the CPU.
We don't need to hack our shader decoder due to game bugs anymore.
Removed in this commit.
On Windows, network shares use paths like \\server\share\file which were
being broken by FileUtil::SanitizePath() removing double slashes.
Changed the code in SanitizePath to permit a double-backslash if it
occurs at the start of a filepath (on Windows only).
Presentation context always has GL_DRAW_FRAMEBUFFER_BINDING as zero.
There is no need to bind the default framebuffer constantly.
According to Nsight this was using ~0.7ms per frame and it broke
renderdoc captures.
This is a reversed look up table extracted from
https://gist.github.com/rygorous/2203834#file-gistfile1-cpp-L41-L62
that is used in
04d4e9e587/source/maxwell/tsc_generate.cpp (L38)
Games usually bind 0xFD expecting a float texture border of 1.0f.
The conversion previous to this commit was multiplying the uint8 sRGB
texture border color by 255. This is close to 1.0f but when that
difference matters, some graphical glitches appear.
This look up table is manually changed in the edges, clamping towards
0.0f and 1.0f.
While we are at it, move this logic to its own translation unit.
Reimplements I2I adding sign extension, saturation (clamp source value
to the destination), selection and destination sizes that are not 32
bits wide.
It doesn't implement CC yet.
Implements a reduction operation. It's an atomic operation that doesn't
return a value.
This commit introduces another primitive because some shading languages
might have a primitive for reduction operations.
Should fixcitra-emu/citra#4593.
As the issue might not be entirely clear, I'll offer a short explanation from what I understood from it and found from experimentation.
Currently yuzu offers the user the option to change the text that's displayed in the "Name" column in the game list. Generally, it is expected that the items are sorted based on the displayed text, but yuzu would sort them by title instead.
Made it so that an access to SortRole returns the same as DisplayRole.
There shouldn't be any UI changes, only change in behaviour.
Also fixes a bug with directory sorting, where having the directories out of order would enable you to try to "move up" to the addDirectory button, which would crash the emulator.

yuzu was already using the header for interpolation, but it was missing
the FragCoord.w multiplication described in the linked pull request.
This commit finally removes the FragCoord.w == 1.0f hack from the shader
decompiler.
While we are at it, this commit renames some enumerations to match
Nvidia's documentation (linked below) and fixes component declaration
order in the shader program header (z and w were swapped).

* IOFile: Make the move constructor and move assignment operator noexcept
Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.
This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.
As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.
* fix various instances of -1 being assigned to unsigned types
* do not assign in conditional statements
* File/IOFile: Check _tfopen_s properly
* common/file_util.cpp: address review comments

The intention behind a Vulkan wrapper is to drop Vulkan-Hpp.
The issues with Vulkan-Hpp are:
- Regular breaks of the API.
- Copy constructors that do the same as the aggregates (fixed recently)
- External dynamic dispatch that is hard to remove
- Alias KHR handles with non-KHR handles making it impossible to use
smart handles on Vulkan 1.0 instances with extensions that were included
on Vulkan 1.1.
- Dynamic dispatchers silently change size depending on preprocessor
definitions. Different files will have different dispatch definitions,
generating all kinds of hard to debug memory issues.
In other words, Vulkan-Hpp is not "production ready" for our needs and
this wrapper aims to replace it without losing RAII and exception
safety.
This information is required to properly implement SULD.B. It might also
be handy for all image operations, since it would allow us to implement
them on devices that require the image format to be specified (on
desktop, this would be AMD on OpenGL and Intel on OpenGL and Vulkan).
Rounding operations only matter when the conversion size of source and
destination is the same, i.e. .F16.F16, .F32.F32 and .F64.F64.
When there is a mismatch (.F16.F32), these bits are used for IEEE
rounding, we don't emulate this because GLSL and SPIR-V don't support
configuring it per operation.
Changes the GraphicsContext to be managed by the GPU core. This
eliminates the need for the frontends to fool around with tricky
MakeCurrent/DoneCurrent calls that are dependent on the settings (such
as async gpu option).
This also refactors out the need to use QWidget::fromWindowContainer as
that caused issues with focus and input handling. Now we use a regular
QWidget and just access the native windowHandle() directly.
Another change is removing the debug tool setting in FrameMailbox.
Instead of trying to block the frontend until a new frame is ready, the
core will now take over presentation and draw directly to the window if
the renderer detects that its hooked by NSight or RenderDoc
Lastly, since it was in the way, I removed ScopeAcquireWindowContext and
replaced it with a simple subclass in GraphicsContext that achieves the
same result
