This increases accuracy, fixing the white rendering in Major Minor's Majestic March. However, the hardware backends can only have one viewport and scissor rectangle at a time, while sometimes multiple are needed to accurately emulate what is happening. If possible, this will need to be fixed later.
I think this is a relic of D3D9. D3D11 and D3D12 seem to work fine without it. Plus, ViewportCorrectionMatrix just didn't work correctly (at least with the viewports being generated by the new scissor code).
These aren't particularly useful, and make the code a bit more confusing. If for some reason someone wants to test what happens when these functions are disabled, it's easier to just edit the code that implements them. They aren't exposed in the UI, so one would need to restart Dolphin to do it anyways.
This message would be logged, usually multiple times, for EVERY. SINGLE. PIXEL. That's pretty much useless and just makes the log unreadable. Plus, the current support (which acts as RGB8) is close enough that for end-user purposes, it's fine. I don't think the hardware backends support RGB565_Z16 and its antialiasing functionality correctly either, but they don't have similar logspam.
It doesn't make sense for alpha to add the bias ONLY when dividing by 2, while color doesn't apply the bias for divide by 2 only; hardware testing indicates that alpha should have the bias.
This fixes the menus in Mario Kart Wii (https://bugs.dolphin-emu.org/issues/11909) but reintroduces the white rectangle in Fortune Street.
This reverts commit 5aaa5141ed (and several other matching changes elsewhere).
Fixes a crash that could occur if the static constructor function for
the MainSettings.cpp TU happened to run before the variables in
Common/Version.cpp are initialised. (This is known as the static
initialisation order fiasco.)
By using wrapper functions, those variables are now guaranteed to be
constructed on first use.
We don't use sampler2DMS, but we do use sampler2DMSArray.
I can't reproduce it on my phone, but a user who was running GLES
on a Tegra X1 reported a shader compilation error related to this.
The benefit to exposing this over the raw BP state is that adjustments Dolphin makes, such as LOD biases from arbitrary mipmap detection, will work properly.
The compiler was loudly announcing each and every branch Tev was not checking in
a switch statement, but Tev has learned it's lesson and will produce that
warning no more.
Currently the logic for addressing the individual TexUnits is splattered all
across dolphin's codebase, this commit attempts to consolidate it all into a
single place and formalise it using our new TexUnitAddress struct.
This fixes various texture offsetting issues with negative texture coordinates (bringing the software renderer in line with the hardware renderers). It also handles the invalid wrap mode accurately (as was done for the hardware renderers in the previous commit). Lastly, it handles wrapping with non-power-of-2 texture sizes in a hardware-accurate way (which is somewhat broken looking, as games aren't supposed to use wrapping with non-power-of-2 sizes); this has not been done for the hardware renderers.

Running the min/max operation on the upside down, quad-rounded pixel
coordinates before inverting them to the standard upper-left origin
produces wrong results. Therefore, we need to do the inversion before
rounding to pixel quads.
We also need to ensure the the CPU does not receive stale values
which have been updated by the GPU. Apparently the buffer here
is not coherent on NVIDIA drivers. Not sure if this is a driver
bug/spec violation or not, one would think that
glGetBufferSubData() would invalidate any caches as needed, but
this path is only used on NVIDIA anyway, so it's fine. A point
to note is that according to ARB_debug_report, it's moved from
video to host memory, which would explain why it needs the
cache invalidate.
MAX_XFB_WIDTH/HEIGHT are the largest XFB sizes seen in practice, but do not make sense to use for the backbuffer size, which should be the size of the window. The old code created screenshots with a size of 720x540 on NTSC games when "Dump Frames at Internal Resolution" is unchecked; now, the window size is used.
When trying to do a small optimization in 8a0f5ea, I failed to
take into account that WeakFlush and FlushOne update m_query_count.
Only D3D11 and OGL had this problem, not D3D12 and Vulkan.
The STL has everything we need nowadays.
I have tried to not alter any behavior or semantics with this
change wherever possible. In particular, WriteLow and WriteHigh
in CommandProcessor retain the ability to accidentally undo
another thread's write to the upper half or lower half
respectively. If that should be fixed, it should be done in a
separate commit for clarity. One thing did change: The places
where we were using += on a volatile variable (not an atomic
operation) are now using fetch_add (actually an atomic operation).
Tested with single core and dual core on x86-64 and AArch64.
Previously we set the texture coordinate to zero, now we set
the texture coordinate *index* to zero. This fixes the ripple
effect of the Mario painting in Luigi's Mansion.
VideoCommon: Change the type of BPMemory.scissorOffset to 10bit signed: S32X10Y10
VideoBackends: Fix Software Clipper.PerspectiveDivide function, use BPMemory.scissorOffset instead of hard code 342
Fixes issue 11393.
The problem is that left and top make no sense for a width by height array; they only make sense in a larger array where from which a smaller part is extracted. Thus, the overall size of the array is provided to CopyRegion in addition to the sub-region. EncodeXFB already handles the extraction, so CopyRegion's only use there is to resize the image (and thus no sub-region is provided).
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare. (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.
Additionally, VCacheEnhance has been added to UVAT_group1. According to YAGCD, this field is always 1.
TVtxDesc also now has separate low and high fields whose hex values correspond with the proper registers, instead of having one 33-bit value. This change was made in a way that should be backwards-compatible.
The special case doesn't appear to make a significant difference in any games, and the current implementation has a (minor, fixable) issue that breaks Super Mario Sunshine (both with a failed assertion (https://bugs.dolphin-emu.org/issues/11742) and a rendering issue (https://bugs.dolphin-emu.org/issues/7476)). Hardware testing wasn't able to reproduce the special case, either, so it may just not exist.
PR #9315 contains a fixed implementation of the special case on all video backends, and can serve as a basis for it being reintroduced if it is found to exist under more specific circumstances. For now, I don't see a reason to keep it present.
We want to clear/memset the padding bytes, not just each member,
so using assignment or {} initialization is not an option.
To silence the warnings, cast the object pointer to u8* (which is not
undefined behavior) to make it explicit to the compiler that we want
to fill the object representation.
In CreateDescriptorSetLayouts(), one less dynamic binding is created when
bSupportsGeometryShaders=false. Reduce the dynamicOffsetCount argument by
one in that case. Avoids this validation error:
Attempting to bind 3 descriptorSets with 2 dynamic descriptors, but
dynamicOffsetCount is 3. It should exactly match the number of dynamic
descriptors. The Vulkan spec states: dynamicOffsetCount must be equal to
the total number of dynamic descriptors in pDescriptorSets
