Stop ignoring image swizzles on depth and stencil images.
This doesn't fix a known issue on Xenoblade Chronicles 2 where an OpenGL
texture changes swizzles twice before being used. A proper fix would be
having a small texture view cache for this like we do on Vulkan.
While Vulkan was assuming we had no negative viewports, OpenGL code
was assuming we had them. Port the old code from Vulkan to OpenGL,
checking if the first viewport is negative before flipping faces.
This is not a complete implementation since we only check for the first
viewport to be negative. That said, unless a game is using Vulkan,
OpenGL and NVN games should be fine here, and we can always compare with
our Vulkan backend to see if there's a difference.
The check to flip faces when viewports are negative were a left over
from the old OpenGL code. This is not required on Vulkan where we have
negative viewports.
Hardware S2R special registers match gl_Thread*MaskNV. We can trivially
implement these using Nvidia's extension on OpenGL or naively stubbing
them with the ARB instructions to match. This might cause issues if the
host device warp size doesn't match Nvidia's. That said, this is
unlikely on proper shaders.
Refer to the attached url for more documentation about these flags.
https://www.khronos.org/registry/OpenGL/extensions/NV/NV_shader_thread_group.txt
Some operations like atomicMin were ignored because they returned were
being stored to RZ. This operations have a side effect and it was being
ignored.
Drop the std::list hack to allocate memory indefinitely.
Instead use a custom allocator that keeps references valid until
destruction. This allocates fixed chunks of memory and puts pointers in
a free list. When an allocation is no longer used put it back to the
free list, this doesn't heap allocate because std::vector doesn't change
the capacity. If the free list is empty, allocate a new chunk.
Most overlaps in the buffer cache only contain one mapped address.
We can avoid close to all heap allocations once the buffer cache is
warmed up by using a small_vector with a stack size of one.
Instead of using boost::icl::interval_map for caching, use
boost::intrusive::set. interval_map is intended as a container where the
keys can overlap with one another; we don't need this for caching
buffers and a std::set-like data structure that allows us to search with
lower_bound is enough.
This has been wrong since 0432af5ad1
I haven't found a game that called this function (and I haven't tried this on a real Switch), and because of this I haven't been able to check if the number in assert OR the string in the assert is wrong, but one of the two is wrong:
NetworkProfileData is 0x18E, while SfNetworkProfileData is 0x17C, according to Switchbrew
Switchbrew doesn't officially say that NetworkProfileData's size is 0x18E but it's possible to calculate its size since Switchbrew provides the size and the offset of all the components of NetworkProfileData (which isn't currently implemented in yuzu, alongside SfNetworkProfileData)
NetworkProfileData documentation: https://switchbrew.org/wiki/Network_Interface_services#NetworkProfileData
SfNetworkProfileData documentation: https://switchbrew.org/wiki/Network_Interface_services#SfNetworkProfileData
Since I trust ogniK's work on reversing NIFM, I'd assume this was just a typo in the string
Add code required to use OpenGL assembly programs based on
NV_gpu_program5. Decompilation for ARB programs is intended to be added
in a follow up commit. This does **not** include ARB decompilation and
it's not in an usable state.
The intention behind assembly programs is to reduce shader stutter
significantly on drivers supporting NV_gpu_program5 (and other required
extensions). Currently only Nvidia's proprietary driver supports these
extensions.
Add a UI option hidden for now to avoid people enabling this option
accidentally.
This code path has some limitations that OpenGL compatibility doesn't
have:
- NV_shader_storage_buffer_object is limited to 16 entries for a single
OpenGL context state (I don't know if this is an intended limitation, an
specification issue or I am missing something). Currently causes issues
on The Legend of Zelda: Link's Awakening.
- NV_parameter_buffer_object can't bind buffers using an offset
different to zero. The used workaround is to copy to a temporary buffer
(this doesn't happen often so it's not an issue).
On the other hand, it has the following advantages:
- Shaders build a lot faster.
- We have control over how floating point rounding is done over
individual instructions (SPIR-V on Vulkan can't do this).
- Operations on shared memory can be unsigned and signed.
- Transform feedbacks are dynamic state (not yet implemented).
- Parameter buffers (uniform buffers) are per stage, matching NVN and
hardware's behavior.
- The API to bind and create assembly programs makes sense, unlike
ARB_separate_shader_objects.
Constant attributes (in OpenGL known disabled attributes) are not
supported on Vulkan, even with extensions. To emulate this behavior we
return zero on reads from disabled vertex attributes in shader code.
This has no caching cost because attribute formats are not dynamic state
on Vulkan and we have to store it in the pipeline cache anyway.
- Fixes Animal Crossing: New Horizons terrain borders
This was a left over from OpenGL when disabled buffers where not properly
emulated. We no longer have to assert this as it is checked in vertex
buffer initialization.
Previously we never cleared the states of the entries and the key would stay held down, also looping over the key bytes for each key lead to setting every bit for the key state instead of the key we wanted
"Not equal" operators on GLSL seem to behave as unordered when we expect
an ordered comparison.
Manually emulate this checking for LGE values (numbers, not-NaNs).

This should fix grass interactions on Breath of the Wild on Vulkan.
It is currently untested against validation layers.
Nvidia's Windows 443.09 beta driver or Linux 440.66.12 is required for
now.
While èis generally representable in some language encodings, in some
it isn't and will result in compilation warnings occurring. To remain
friendly with other language's codepages on Windows, we normalize it to
an ASCII e.

Return the proper state of vr mode for IsVrModeEnabled
We should not return an error for SetVrModeEnabled. When VR Mode is turned on, it signals to lbl to turn vr mode on, not return an error code
Reduces some header churn and reduces rebuilds when some header
internals change.
While we're at it we can also resolve a missing include in buffer_cache.
Xenoblade 2 invokes a draw call with zero vertices.
This is likely due to indirect drawing (glDrawArraysIndirect).
This causes a crash in the staging buffer pool when trying to create a
buffer with a size of zero. To workaround this, skip index buffer setup
entirely when the number of indices is zero.
Drop MemoryBarrier from the buffer cache and use Maxwell3D's register
WaitForIdle.
To implement this on OpenGL we just call glMemoryBarrier with the
necessary bits.
Vulkan lacks this synchronization primitive, so we set an event and
immediately wait for it. This is not a pretty solution, but it's what
Vulkan can do without submitting the current command buffer to the queue
(which ends up being more expensive on the CPU).
Using deko3d as reference:
4e47ba0013/source/maxwell/gpu_3d_state.cpp (L42)
We were using bits 3 and 4 to determine depth clamping, but these are
the same both enabled and disabled:
state->depthClampEnable ? 0x101A : 0x181D
The same happens on Nvidia's OpenGL driver, where they do something like
this (default capabilities, GL 4.5 compatibility):
(state & DEPTH_CLAMP) != 0 ? 0x201a : 0x281c
There's always a difference between the first bits in this register, but
bit 11 is consistently disabled on both deko3d/NVN and OpenGL. This
commit changes yuzu's behaviour to use bit 11 to determine depth
clamping.
- Fixes depth issues on Super Mario Odyssey's intro.
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.
Deduplicate code shared between vk_pipeline_cache and gl_shader_cache as
well as shader decoder code.
While we are at it, fix a bug in gl_shader_cache where compute shaders
had an start offset of a stage shader.
Signed integer addition overflow might be undefined behavior. It's free
to change operations to UAdd and use unsigned integers to avoid
potential bugs.
P2R CC takes the state of condition codes and puts them into a register.
We already have this implemented for PR (predicates). This commit
implements CC over that.
Sometimes for unknown reasons NVN games can bind a render target format
of 0. This may be a yuzu bug.
With the commits before this the formats were specified without being
"packed", assuming all formats and texceptions will be written like in
the color_attachments vector.
To address this issue, iterate all render targets and pack them as they
are valid. This way they will match color_attachments.
- Fixes validation errors and graphical issues on Breath of the Wild.
Currently SetBufferCount doesn't write to the out buffer which then contains uninitialized data. This leads to non-zero data which leads to responding with different error codes
We can also allow unicorn to be constructed in 32-bit mode or 64-bit
mode to satisfy the need for both interpreter instances.
Allows this code to compile successfully of non x86-64 architectures.
Any time the lambda function is called, the permission being used in the
capture would be passed in as an argument to the lambda, so the capture
is unnecessary.
The encoding for negation and absolute value was wrong.
Extracting is now done manually. Similar instructions having different
encodings is the rule, not the exception. To keep sanity and readability
I preferred to extract the desired bit manually.
This is implemented against nxas:
8dbc389957/table.h (L68)
That is itself tested against nvdisasm (Nvidia's official disassembler).
This allows deducing some properties from the texture instruction before
asking the runtime. By doing this we can handle type mismatches in some
instructions from the renderer instead of the shader decoder.
Fixes texelFetch issues with games using 2D texture instructions on a 1D
sampler.
Patch the RomFS with the selected updates before dumping. Previously the resulting RomFS only contained data from the original title.
To dump the RomFS without updates the user can disable the update under Properties before choosing Dump RomFS.
The intention behind this was to assign a float to from an uint32_t, but
it was unintentionally being copied directly into the std::optional.
Copy to a temporary and assign that temporary to std::optional. This can
be replaced with std::bit_cast<float> once we are in C++20.
All drivers (even Intel) seem to have a device local memory type that is
not host visible. Remove this flag so all devices follow the same path.
This fixes a crash when trying to map to host device local memory on
integrated devices.
Introduce a default buffer getter that lazily constructs an empty
buffer. This is intended to match OpenGL's buffer 0.
Use this for disabled vertex and uniform buffers.
While we are at it, include vertex buffer usages for staging buffers to
silence validation errors.
On NVN buffers can be enabled but have no size. According to deko3d and
the behavior we see in Animal Crossing: New Horizons these buffers get
the special address of 0x1000 and limit themselves to 0xfff.
Implement buffers without a size by binding a null buffer to OpenGL
without a side.

Sort discrete GPUs over the rest, Nvidia over AMD, AMD over Intel, Intel
over the rest. This gives us a somewhat consistent order when Optimus
is removed (renderdoc does this when it's attached).
This can break the configuration of users with an Intel GPU that
manually remove Optimus on yuzu. That said, it's a very unlikely to
happen.
Pad FixedPipelineState's size to 384 bytes to be a multiple of 16.
Compare the whole struct with std::memcmp and hash with CityHash. Using
CityHash instead of a naive hash should reduce the number of collisions.
Improve used type traits to ensure this operation is safe.
With these changes the improvements to the hashable pipeline state are:
Optimized structure
Hash: 89 ns
Comparison: 103 ns
Construction*: 164 ns
Struct size: 384 bytes
Original structure
Hash: 148 ns
Equal: 174 ns
Construction*: 281 ns
Size: 1384 bytes
* Attribute state initialization is not measured
These measures are averages taken with std::chrono::high_accuracy_clock
on MSVC shipped on Visual Studio 16.6.0 Preview 2.1.
Avoids unnecessary reference count increments where applicable and also
avoids reallocating a vector.
Unlikely to make a huge difference, but given how trivial of an
amendment it is, why not?
Many of these implementations are used to implement a polymorphic
interface. While not directly used polymorphically, this prevents
virtual destruction from ever becoming an issue.
Given the std::vector was const, an automatic move out of the function
could not occur.
We can allow automatic return value optimizations to occur by making the
buffer non-const.
Nvidia recently introduced a new memory type for data streaming
(awesome!), but yuzu was assuming that all heaps had enough memory
for the assumed stream buffer size (256 MiB).
This worked fine on AMD but Nvidia's new memory heap was smaller than
256 MiB. This commit changes this assumption and allocates a bit less
than the size of the preferred heap, with a maximum of 256 MiB (to avoid
allocating all system memory on integrated devices).
- Fixes a crash on NVIDIA 450.82.0.0
1. Ensure that register information available to gdbstub is most up-to-date.
2. There's no reason to check for current_thread == thread when emitting a trap.
Doing this results in random hangs whenever a step happens upon a thread switch.
Some variables aren't used, so we can remove these.
Unfortunately, diagnostics are still reported on structured bindings
even when annotated with [[maybe_unused]], so we need to unpack the
elements that we want to use manually.
These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.
Now that the flags are enabled, we can freely change the interface to
make these unnecessary.
Implement indexed quads (GL_QUADS used with glDrawElements*) with a
compute pass conversion.
The compute shader converts from uint8/uint16/uint32 indices to uint32.
The format is passed through push constants to avoid having different
variants of the same shader.
- Used by Fast RMX
- Used by Xenoblade Chronicles 2 (it still has graphical due to
synchronization issues on Vulkan)
Neither core nor web_services use OpenSSL nor LibreSSL.
However they need to link them as it's a requirement of httplib.
So let's declare this within httplib instead of core and web_services.
The original idea of returning pointers is that handles can be moved.
The problem is that the implementation didn't take that in mind and made
everything harder to work with. This commit drops pointer to handles and
returns the handles themselves. While it is still true that handles can
be invalidated, this way we get an old handle instead of a dangling
pointer.
This problem can be solved in the future with sparse buffers.
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.
It's undefined behavior to pass a null pointer to std::fread and
std::fwrite, even if the length passed in is zero, so we must perform
the precondition checking ourselves.
A common case where this can occur is when passing in the data of an
empty std::vector and size, as an empty vector will typically have a
null internal buffer.
While we're at it, we can move the implementation out of line and add
debug checks against passing in nullptr to std::fread and std::fwrite.
This can result in silent logic bugs within code, and given the amount
of times these kind of warnings are caused, they should be flagged at
compile-time so no new code is submitted with them.
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.
Adds optional support for Nsight Aftermath. It is enabled through
ENABLE_NSIGHT_AFTERMATH in cmake. A path to the SDK has to be provided
by the environment variable NSIGHT_AFTERMATH_SDK.
Nsight Aftermath allows an application to generate "minidumps" of the
GPU state when a device loss happens. By analysing these on Nsight we
can know what a game was doing and why it triggered a device loss.
The dump is generated inside %APPDATA%\yuzu\log\gpucrash and this
directory is deleted every time a new instance is initialized with
Nsight enabled.
To enable it on yuzu there has a to be a driver and device capable of
running Nsight Aftermath on Vulkan. That means only Turing based GPUs
on the latest stable driver, beta drivers won't work for now.
It is manually enabled in Configuration>Debug>Enable Graphics Debugging
because when using all debugging capabilities there is a runtime cost.
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.
