The advantage of std::list is that elements can be removed from the
middle efficiently, but we don't actually need that, because the
ordering of the elements doesn't matter for us. We can just replace the
element we want to remove with the last element and then call pop_back.
Replacing list with vector should speed up looping through the elements.
GameTracker's usage of GameFileCache is thread-safe even without
using a mutex. All of its access to GameFileCache happens on the
thread m_load_thread, except for the call to GameFileCache::Load,
which finishes before m_load_thread starts executing.
Starting with 5.0-5504, trying to launch DolphinQt2 from Visual Studio
shows the error message "The operation could not be completed. Undefined
error" instead of launching the exe file. (The exe gets created
correctly, it just doesn't get launched. It's possible to work around
the problem by launching the exe manually outside of Visual Studio, but
then you won't have an attached debugger automatically.) This commit
fixes that by removing headers from DolphinQt2.vcxproj's ClInclude list
that already are in the QtMoc list. (The problem was originally about
LogWidget.h and LogConfigWidget.h, but 5.0-5600 made the problem be
about CheatWarningWidget.h and GeckoCodeWidget.h instead.)
There are two reasons for this change:
1. It removes many repetitive lines of code.
2. I think it's a good idea to enable the use of old-style section
names even for settings that previously haven't been settable in game
INIs. Mixing the two styles in INIs (using the new style only for new
settings) is not ideal, and people on the forums don't even seem to
know that the new style exists (nobody knew a way to set ubershader
settings per game, for instance). Encouraging everyone to start using
only the new style might work long-term, but it would take take time
and effort to make everyone get used to it. Considering that this commit
*reduces* the amount of code by adding the ability to use old-style
names for more settings, I'd say that adding this ability is worth it.
Trying to force the XSI version by undefining _GNU_SOURCE can lead
to compilation errors on some systems because of headers expecting
that _GNU_SOURCE is defined.
This commit uses define checks to detect which version we have.
I tried making an overloaded function (int and const char*) instead,
but that led to a warning about one of the variants being unused.
The Time Base Register was added under the BAT registers. TBL and TBU
were ORed together to get one 64-bit value to display. It is labeled TB
The Graphics Quantisation Registers were added under the Segment
Registers. They are Labeled GQR0-GQR7.
All new registers are read only.
GLES doesn't support C-style array initialisers, so stuff like:
Type var[2] = {
VALUE_A,
VALUE_B
};
isn't supported in GLES (it was added in
GL_ARB_shading_language_420pack).
The texture conversion shader used this, so would fail to compile on
GLES.
The PC offset ADRP() path takes a s32 value, but the input offset was
being tested as abs(ptr) < 0xFFFFFFFF. This caused values between
0x80000000 and 0xFFFFFFFF to incorrectly use this path, despite the
offsets not being representable in an s32.
This caused a crash in the VertexLoader on android 8.1 immediate in wind
waker (and possibly all other apps on android 8.1) as the jit and data
sections happened to be loaded 4gb apart in virtual memory, causing some
pointers to hit this
Some homebrew expect exception handlers to be present -- which is
almost always the case on console, since most of the time homebrew are
launched from either a libogc or SDK title) -- and break if they are
not. To fix this, we just need to include default, dummy handlers.
Set HID0, HID4, GPR1 to values that are used by libogc for
initialisation. This makes boots more similar to a launch
from the HBC or another loader, since normally the registers
have already been initialised by the loader.
This fixes a crash in homebrew that assume GPR1 points to a correct
location and attempt to use it before initialising registers.
HLSL does not define roundEven(), only round(). This means that the
output may differ slightly for OpenGL vs Direct3D. However, it ensures
consistency across OpenGL drivers, as round() in GLSL can go either way.
These three instructions use the B field (bits 16-20 of the opcode)
to determine what the operand register is. However, the code was
using the path that uses the C field (bits 21-25).
This amends the code to use the B field (and also fixes the 64-bit PPC
opcodes, because why not?).
Fixes issue 10683.
This fixes the rendering of the scan visor in Metroid Prime 2: Echoes,
as seen in https://fifoci.dolphin-emu.org/dff/mp2-scanner/
The alpha channel was off-by-one on Ivy Bridge due to the rounding
after multiplication with colmat. This commit removes this matrix
altogether in most cases, making them simple GLSL swizzles.
This will generate one shader per copy format. For now, it is the same
shader with the colmat hard coded. So it should already improve the GPU
performance a bit, but a rewrite of the shader generator is suggested.
Half of the patch is done by linkmauve1:
VideoCommon: Reorganise the shader writes.
Currently, a simple typo in the system name will trigger an assert
message that complains about a "programming error". This is not
user friendly and misleading.
So this changes GetSystemFromName to return an std::optional, which
allows for callers to check whether the system exists and handle
failures better.
Manually convert each argument to a UTF-8 std::string, because the
implicit conversion for wxCmdLineArgsArray to char** calls ToAscii
(which is obviously undesired).

Also skips swapping the window system buffers in headless mode, as there
may not be a surface which can be swapped in the first place. Instead,
we call glFlush() at the end of a frame in this case.
Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.
We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.
This was causing an issue where DolphinQt couldn't save graphics options
(DolphinWX doesn't hit this code path), because this function was being
called before the in-memory config was flushed to disk.
With this PR, the in-memory config isn't reset, and only SYSCONF-related
variables may get changed.
7f0834c9 moved the locations of the Real XFB (now XFB to RAM) and
Disabled XFB (now Immediate Mode) settings. There are programs
other than Dolphin that parse DTM headers, so this is not good.
Note that Immediate XFB actually is the inversion of Disabled XFB.
I hope that's not too much of a problem...
All file scope variables are able to be made internally linked.
CD3DFont is essentially used as an extension to the utility interface, so
this is able to be made internal as well, removing a global from
external view.
This lets Dolphin know if a configured GameCube Controller should actually
be treated as connected or not.
Talked to @JMC47 a bit about this last night. My use-case is that all of
my controllers are the same hardware (Xbox One controllers) so share the
same configuration (modulo device number). Treating them all as always
connected isn't a problem for most games, but in some (Smash Bros.) it
forces me to go find a keyboard/mouse and unconfigure any controllers
that I don't actually have connected. Hotplugging devices (works on macOS,
at least) + this patch remove my need to ever touch the Controller Config
dialog while in a game.
This patch makes the following changes:
- A new `BooleanSetting` in `GCPadEmu` called "Always Connected", which
defaults to false.
- `ControllerEmu` tracks whether the default device is connected on every
call to `UpdateReferences()`.
- `GCPadEmu.GetStatus()` now sets err bit to `PAD_ERR_NO_CONTROLLER` if
the default device isn't connected.
- `SIDevice_GCController` handles `PAD_ERR_NO_CONTROLLER` by imitating the
behaviour of `SIDevice_Null` (as far as I can tell, this is the only use
of the error bit from `GCPadStatus`).
I wanted to add an OSD message akin to the ones when Wiimotes get
connected/disconnected, but I haven't yet found where to put the logic.
This is already initialized in the class definition. This would
previously cause a -Wreorder warning on macOS, as m_config is
defined after m_currently_mapped.
Originally, Layer contained a std::map of Sections, which containted a std::map
containing the (key, value) pairs. Here we flattern this structure so that only
one std::map is required, reducing the number of indirections required and
vastly simplifying the code.
We need this because VS currently doesn't consider
std::is_trivially_copyable<typename
std::remove_volatile<SCPFifoStruct>::type>::value
to be true and because no compiler should consider it
to be true if we replace the volatiles with atomics.
No code is relying on this unexplained null byte check, since
the only code that calls UTF16ToUTF8 on non-Windows systems
is UTF16BEToUTF8, which explicitly strips null bytes.
Axis range was previously calculated as max + abs(min), which relies on the assumption that
min will not exceed 0. For (min, max) values like (0, 255) or (-128, 127), which I assume to
be the most common cases, the range is correctly calculated as 255. However, given (20,
235), the range is erroneously calculated as 255, leading to axis values being normalized
incorrectly.
SDL already handles this case correctly. After changing the range calculation to max - min,
the axis values received from the evdev backend are practically identical to the values
received from the SDL backend.
We shouldn't try to create folder names that contain characters
such as : or / since they are forbidden or have special meanings.
(No officially released disc uses such characters, though.)
There has been a lot of confusion about what the CPU clock override
section does among users, and looking at it… I’m not surprised! It
doesn’t directly state which CPU clock rate is being overridden!
This small change adjusts the language to clarify that the emulated CPU
is being adjusted.
The main problem was that the volume of the mixer wasn't savestated.
The volume is typically 0 at the beginning of a game, so loading a
savestate at the beginning of a game would lead to silent DTK audio.
I also added savestating to StreamADPCM.cpp.
Nowadays that Dolphin detects regions of discs properly and doesn't
force programs with unknown regions (such as homebrew) into running
under a certain region, the "Force Console as NTSC-J" option is
practically useless for making anything run correctly. Enabling it
is however an easy way to totally break many non-Japanese games.
The earlier code always tried to use TitleDatabase for getting
title names, but that didn't work for disc-based games, because
there was no way to get the maker ID.
Unlike VEN, the endpoint is determined by the value at 8-12.
If it's non-zero, HID submits the request to the interrupt OUT
endpoint. Otherwise, the request is submitted to the IN endpoint.
This commit changes HIDv5 to keep track of endpoints (like IOS does)
and use them when submitting interrupt transfers.
This implements /dev/usb/hid v5, found in IOS57, IOS58 and IOS59.
This is an initial implementation that ignores some differences
with VEN because I lack understanding of what IOS is actually doing
sometimes. These are documented on the WiiBrew article:
https://wiibrew.org/wiki//dev/usb/hid_(v5)
One major difference that this implementation handles is about IDs.
It turns out Nintendo has decided to include the interface number in
the top byte of HIDv5 device IDs, unlike VEN -- even though everything
else about ioctl 1 is otherwise the same!
USBv5 IOS resource managers share most of their code. Some ioctls
are even completely the same! So let's separate the common code
from the VEN specific stuff to make HIDv5 easier to implement.
The descriptor copy code is not actually the same in HIDv4 and VEN,
so it did not make a lot of sense to put it in USB/Common.cpp.
Separate and move it to HIDv4 and VEN.
This cleanup is important because there are even more differences
between HIDv4 and HIDv5.
Fix the device ID struct to reflect the actual structure used by IOS.
It turns out that offset 2 is the internal device index. The reason
that field seemed to be "0x1e - interface_number" is that IOS only
keeps track of 32 devices and always looks for free entries from
the end of the internal array. With each USB interface being exposed
as a separate USBv5 device, "0x1e - interface_number" was mostly
correct... but wrong!
We also made the assumption that the interface number can be
identified from just a USBV5 device ID, which is definitely not true.
VEN (and HID) keep track of the interface number in the internal struct
instead of "reconstructing" it from the device ID (which is normally
not possible if we were generating IDs correctly)
This commit fixes all of these inaccuracies.
Some lines of code in Dolphin just plainly grabbed the value of
g_ActiveConfig.iEFBScale, which resulted in Auto being treated as
0x rather than the actual automatically selected scale.
This reverts commit 1fc910b3ea,
replacing the old INI setting EFBScale with a new INI setting
called InternalResolution, which has a simpler mapping:
| EFBScale | InternalResolution
----------------- | -------------------- | --------------------
Auto (fractional) | 0 |
Auto (integral) | 1 | 0
1x | 2 | 1
1.5x | 3 |
2x | 4 | 2
2.5x | 5 |
3x | 6 | 3
4x | 7 | 4
5x | 8 | 5
6x | 9 | 6
All the fractional IRs were removed in f090a943.
It is not possible to tell whether DLC contents are supposed to be
present on the NAND or not, because they're treated as "optional".
So this commit changes the NAND check to not consider missing
contents for DLC titles as an issue.
"N/A" can be awkward to handle in translations.
I don't think there's much point in showing "N/A" rather than
leaving the description box blank, so let's just leave it blank.
Use std::string(cstring, strnlen(cstring, max_length)) instead of
trying to remove extra null characters manually, which is a bit
ugly and error prone.
And indeed, the original code contained a bug which would cause
extra NULLs to not be removed at all if the string did not
end with a NULL -- causing issues down the road when constructing
paths for sub-entries.
Because the Wii NAND size is finite, mark titles that were installed
only for booting as temporary, and remove them whenever we need to
install another title (to make room). This is exactly what the
System Menu does for temporary SD card title data.
