texture serialization and deserialization used to involve many memory
allocations and deallocations, along with many copies to and from
those allocations. avoid those by reserving a memory region inside the
output and writing there directly, skipping the allocation and copy to
an intermediate buffer entirely.
This avoids some warnings, which were originally fixed by ignoring loads with a value of zero (see 636bedb207 / #3242).
Note that FifoCI will report some changes, but only on the first frame; these seem to be timing related as they don't happen if a different write is used to replace skipped ones.
They appear to relate to perf queries, and combining them with truely unknown commands would probably hide useful information. Furthermore, 0x20 is issued by every title, so without this every title would be recorded as using an unknown command, which is very unhelpful.
debaf63fe8 moved the "Sonic epsilon hack"
to vertex shaders. However, it was only done for targets with depth
clamping. If this is not available, for example the target is OpenGL ES,
the Sonic problem appears (https://bugs.dolphin-emu.org/issues/11897).
A version of the "Sonic epsilon hack" is added for targets without
depth clamping.
BPMEM_TEV_COLOR_ENV + 6 (0xC6) was missing due to a typo. BPMEM_BP_MASK (0xFE) does not lend itself well to documentation with the current FIFO analyzer implementation (since it requires remembering the values in BP memory) but still shouldn't be treated as unknown. BPMEM_TX_SETMODE0_4 and BPMEM_TX_SETMODE1_4 (0xA4-0xAB) were missing entirely.
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.
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.
Cel-damage depends on lighting being calculated for the first channel
even though there is no color in the vertex format (defaults to the
material color). If lighting for the channel is not enabled, the vertex
will use the default color as before.
The default value of the color is determined by the number of elements in
the vertex format. This fixes the grey cubes in Super Mario Sunshine.
If the color channel count is zero, we set the color to black before the
end of the vertex shader. It's possible that this would be undefined
behavior on hardware if a vertex color index that was greater than the
channel count was used within TEV.
Now that we've converted all of the shader generators over to using fmt,
we can drop the old Write() member function and perform a rename
operation on the WriteFmt() to turn it into the new Write() function.
All changes within this are the removal of a <cstdarg> header, since the
previous printf-based Write() required it, and renaming. No functional
changes are made at all.
Completes the migration over to using the fmt-formatting WriteFmt
function. The next PR will rename all usages of WriteFmt, while
simultaneously getting rid of the old printf code.
Replace it with a function-local static that is initialized on first
use. This gets rid of a global variable and removes the need for
manual initialization in UICommon.
This commit also replaces the weird find_if that looks for a non-null
unique_ptr with a simple "is vector empty" check considering that
none of the pointers can be null by construction.
Continues migration of the shader generators over to fmt.
With this, all that's left to move over are the pixel shaders (regular
and ubershader variants)
Adding AmdPowerXpressRequestHighPerformance
This will allow AMD drivers to detect the request to use the dGPU instead of the iGPU on compatible hybrid graphics systems.

Fixes https://bugs.dolphin-emu.org/issues/12245.
I considered making a change to DolphinQt instead of
the core, but then additional effort would've been
required to add the same fix to the Android GUI once
we start using the new config system there.
This is now unused. Seems like it was an improper fix
(there would be a race if saving the screenshot took longer
than 2 seconds) back when it was used too.
Other than the controller settings and JIT debug settings,
these are the only settings which were defined in Java code
but not defined in the new config system in C++. (There are
still a lot of settings that are defined in the new config
system but not yet saveable in the new config system, though.)
While manually capturing constexpr variables used in lambda
expressions does work, it's really easy to forget doing so since
we don't have a Windows CMake builder and the workaround isn't
necessary anywhere else. Fortunately, MSVC has a flag that fixes
the constexpr capture behavior, so let's use that instead.
These are only ever used with ShaderCode instances and nothing else.
Given that, we can convert these helper functions to expect that type of
object as an argument and remove the need for templates, improving
compiler throughput a marginal amount, as the template instantiation
process doesn't need to be performed.
We can also move the definitions of these functions into the cpp file,
which allows us to remove a few inclusions from the ShaderGenCommon
header. This uncovered a few instances of indirect inclusions being
relied upon in other source files.
One other benefit is this allows changes to be made to the definitions
of the functions without needing to recompile all translation units that
make use of these functions, making change testing a little quicker.
Moving the definitions into the cpp file also allows us to completely
hide DefineOutputMember() from external view, given it's only ever used
inside of GenerateVSOutputMembers().
A very trivial conversion, this simply converts calls to Write over to
WriteFmt and adjusts the formatting specifiers as necessary.
This also allows the const char* parameters to become std::string_view
instances, allowing for ease of use with other string types.
Lambda expressions with uncaptured constants were leading to errors,
and there were also some warnings about deprecated functions
(QFontMetrics::width and inet_ntoa).
It actually maps to postMtxInfo, not posMtxInfo (which isn't a thing).
This is especially confusing because there *are* position matrices (as
opposed to post-transform matrices).
It used to be the case that frame advance skipped duplicate frames
(i.e. it would take 30 frame advances to get through one second
of emulated time in a 30 fps game), but this broke in 9c5c3c0.
Skipping duplicate frames making TASing less annoying.
Hardware tests have shown that if the number of texgens/channels do not
match, you get garbage rendering. Presumably because the output
registers from the XF stage are fed into the incorrect input registers
for TEV/BP.
Currently, this causes Dolphin to crash/generate invalid shaders with an
assertion failure in the hardware backends. Instead, we log an error.
Perhaps in the future we should just spit out all texgens/colors anyway
from both stages, and let cross-stage optimization take care of DCE'ing
it away. But doing so would require changing the UIDs and invalidating
everyone's shader caches.
It seems that the newer version of fmt gets tripped up by bitfields
within structs. However, we can just specify the intended type where
necessary to get around this.
Migrates the shader generator off the use of a global array, eliminating
the use of some global state. This also allows us to move the shader
generation over to using fmt in a subsequent change.
Currently, we do not display every second frame in 25fps/30fps games
which run to vsync. This improves performance as there's less rendering
for the GPU to perform, but when combined with vsync, could cause frame
pacing issues.
This commit adds an option to force every frame generated by the console
to be displayed to the host, which may improve pacing for these games.
The frame number is incremented before the first frame is swapped out.
Fixes ffmpeg creating invalid video files on output if the emulator only
runs for a single frame, e.g. FifoCI.
Now that we have an actual interface to manage things, we can stop
duplicating the calls to to the pixel shader manager and remove the
need to remember to actually do so when disabling or enabling the
bounding box.
Rather than expose the bounding box members directly, we can instead
provide an interface for code to use. This makes it nicer to transition
from global data, as the interface function names are already in
place.
Now that we've extracted all of the stateless functions that can be
hidden, it's time to make the index generator a regular class with
active data members.
This can just be a member that sits within the vertex manager base
class. By deglobalizing the state of the index generator we also get rid
of the wonky dual-initializing that was going on within the OpenGL
backend.
Since the renderer is always initialized before the vertex manager, we
now only call Init() once throughout the execution lifecycle.
We can use if constexpr with the template functions that pass in a
non-type template parameter, allowing the removal of branches that
aren't taken at compile time.
Compilers will generally do this by default, however, we now give a
gentle prodding to the compiler if this would otherwise not be the case.
These don't rely on any of the static members within the IndexGenerator
class, so we can make all of these functions fully internal to the
translation unit.
We can make use of if constexpr in several scenarios here to allow
compilers to exise the relevant code paths out.
Technically a decent compiler would do this already, but now we can give
compilers a little more nudging here in the event that isn't the case.
cmd2 is a u32, so any bitwise arithmetic on it with a type of the same
size or smaller will result in a u32 value. This is also implicitly
converted to an unsigned type in the if statement as well, given that
size_t * int -> size_t.
This is just more explicit about the operations occurring and also
likely silences a sign conversion warning.
We only use these string streams to output into a final std::string
instance, we don't read into types with them. Because of this, we can
just make use of std::ostringstream, rather than the fully-fledged
std::stringstream.
No behavioral change. This is intended to make the transition to fmt
less noisy in subsequent changes by combining insertions of multiple
string literals into one where applicable.
Begins the conversion of the shader generators over to using fmt
formatting specifiers.
This also has a benefit over the older StringFromFormat-based API in
that all formatted data is appended to the existing buffer rather than
creating a completely separate string and then appending it to the
internal string buffer.
Migrates most of VideoCommon over to using fmt, with the exception being
the shader generator code. The shader generators are quite large and
have more corner cases to deal with in terms of conversion (shaders have
braces in them, so we need to make sure to escape them).
Because of the large amount of code that would need to be converted, the
conversion of VideoCommon will be in two parts:
- This change (which converts over the general case string formatting),
- A follow up change that will specifically deal with converting over
the shader generators.
OpenGL doesn't render to a 2-layer backbuffer like D3D/Vulkan for quad-buffered
stereo, instead drawing twice with the eye selected by glDrawBuffer()
(see OGL::Renderer::RenderXFBToScreen).
This is a giant hack which was previously removed because it causes
broken rendering. However, it seems that some devices still do not
support logical operations (looking at you, Adreno/Mali). Therefore, for
a handful of cases where the hack actually makes things slightly better,
we can use it.
... but not without spamming the log with warnings. With my warning
message PR, we can inform the users before emulation starts anyway.
Same behavior without hardcoding the type of the mutex within the lock
guards. This means the type of the mutex would be able to be changed
without needing to also change all occurrences lock guards are used.
Allows callers to std::move strings into the functions (or automatically
assume the move constructor/move assignment operator for rvalue
references, potentially avoiding copies altogether.
ash!!
