Previously this check is in GetSurface (if (addr == 0)). This worked fine because GetTextureSurface directly forwarded the address value to GetSurface. However, now with mipmap support, GetTextureSurface would call GetSurface several times with different address offset, resulting some >0 but still invalid address in case the input is 0. We should error out early on invalid address instead of sending it furthor down which would cause invalid memory access
* gdbstub: fix IsMemoryBreak() returning false while connected to client
As a result, the only existing codepath for a memory watchpoint hit to break into GDB (InterpeterMainLoop, GDB_BP_CHECK, ARMul_State::RecordBreak) is finally taken,
which exposes incorrect logic* in both RecordBreak and ServeBreak.
* a blank BreakpointAddress structure is passed, which sets r15 (PC) to NULL
* gdbstub: DynCom: default-initialize two members/vars used in conditionals
* gdbstub: DynCom: don't record memory watchpoint hits via RecordBreak()
For now, instead check for GDBStub::IsMemoryBreak() in InterpreterMainLoop and ServeBreak.
Fixes PC being set to a stale/unhit breakpoint address (often zero) when a memory watchpoint (rwatch, watch, awatch) is handled in ServeBreak() and generates a GDB trap.
Reasons for removing a call to RecordBreak() for memory watchpoints:
* The``breakpoint_data`` we pass is typed Execute or None. It describes the predicted next code breakpoint hit relative to PC;
* GDBStub::IsMemoryBreak() returns true if a recent Read/Write operation hit a watchpoint. It doesn't specify which in return, nor does it trace it anywhere. Thus, the only data we could give RecordBreak() is a placeholder BreakpointAddress at offset NULL and type Access. I found the idea silly, compared to simply relying on GDBStub::IsMemoryBreak().
There is currently no measure in the code that remembers the addresses (and types) of any watchpoints that were hit by an instruction, in order to send them to GDB as "extended stop information."
I'm considering an implementation for this.
* gdbstub: Change an ASSERT to DEBUG_ASSERT
I have never seen the (Reg[15] == last_bkpt.address) assert fail in practice, even after several weeks of (locally) developping various branches around GDB. Only leave it inside Debug builds.
udp_server might not be created due to error (occupied port etc.), in which case its destructor and thread-ending call chain will not be excuted in Server::Stop. However, the ending packet still need to be send no matter udp is on or not, so move it to Server::Stop
MSVC does not seem to like using constexpr values in a lambda that were declared outside of it.
Previously on MSVC build the hotkeys to inc-/decrease the speed limit were not working correctly because in the lambda the SPEED_LIMIT_STEP had garbage values.
After googling around a bit I found: https://github.com/codeplaysoftware/computecpp-sdk/issues/95 which seems to be a similar issue.
Trying the suggested fix to make the variable static constexpr also fixes the bug here.
Makes it consistent with the regular standard containers in terms of
size representation. This also gets rid of dependence on our own
type aliases, removing the need for an include.
The necessity of this parameter is dubious at best, and in 2019 probably
offers completely negligible savings as opposed to just leaving this
enabled. This removes it and simplifies the overall interface.
video_core: shorten GetGLSLVersionString
video_core: make GLES version and extensions consistent
video_core: move some logic to LoadShader
video_core: deduplicate fragment shader precision specifier
The comment already invalidates itself: neither MMIO nor rasterizer cache belongsHLE kernel state. This mutex has a too large scope if MMIO or cache is included, which is prone to dead lock when multiple thread acquires these resource at the same time. If necessary, each MMIO component or rasterizer should have their own lock.
To eliminate System::GetInstance usage. Archive type like SelfNCCH and SaveData changes the actual reference path for different client, so archive backend interface should accept client information from the service interface. Currently we only pass the program ID as the client information.
The UI file is rewritten, to better make use of Qt's layouts (instead of depending on abstract geometry). "Add Cheat", "Save", "Delete" buttons are also added.
The UI logic should be rather easy and usable (IMO), but the code may seem a bit dirty. If anyone has a better idea regarding UI logic design or code implementation, feel free to tell me about it.
Added a few interfaces for adding/deleting/replacing/saving cheats. The cheats list is guarded by a std::shared_mutex, and would only need a exclusive lock when it's being updated.
I marked the `Execute` function as `const` to avoid accidentally changing the internal state of the cheat on execution, so that execution can be considered a "read" operation which only needs a shared lock.
Whether a cheat is enabled or not is now saved by a special comment line `*citra_enabled`.
To break a circular reference formed by process->handle_table->shared_memory->process. Since SharedMemory uses its owner process in the destructor, which is not kept alive by SharedMemory any more, we need to make sure that the lifetime of process is longer than the shared memory. To partially resolve this, Process now explicitly releases shared memory first in its destructor. This is with the assumtion that there is no inter-process reference to shared memory on exit, which is not true when we introduce more multi-process emulation. A TODO is left there for this, as more RE needs to be done on how 3DS handles this situation
This commit it automatically generated by command in zsh:
sed -i -- 's/BitField<\(.*\)_le>/BitField<\1>/g' **/*(D.)
BitField is now aware to endianness and default to little endian. It expects a value representation type without storage specification for its template parameter.
This is compromise for swap type being used in union. A union has deleted default constructor if it has at least one variant member with non-trivial default constructor, and no variant member of T has a default member initializer. In the use case of Bitfield, all variant members will be the swap type on endianness mismatch, which would all have non-trivial default constructor if default value is specified, and non of them can have member initializer
According to documentation, if the argument of std::exp is zero, one is returned.
However we want the return value to be also zero in this case so no audio is played.
The V-Sync option is fundamentally broken in Citra, so let's do the same as yuzu and remove it entirely for SDL2 and at least from the frontend for QT.
(It was also only used by 7.3% of users)
Just two minor fixes:
1. Font color is black in dark theme. It is now only black for pings.
2. If a user is called `abc`, you can ping them by `@abc_`. Now a ping only takes effect when there are spaces around it.
std::make_unique for arrays is equivalent to doing:
std::unique_ptr<T>(new typename std::remove_extent<T>::type[size]())
(note the ending () after the array size specifier). This means that the
default value within memory for the constructed types will be whatever
the default constructor for that type does. Given the built-in
type for std::uint8_t doesn't have a constructor, this is equivalent to
forcing zero-initialization, so the memory will already be zeroed out on
construction. Because of that, there's no need to zero it out again.
We can hide the direct array from external view and instead provide
functions to retrieve the necessary info. This has the benefit of
completely hiding the makeup of the SinkDetails structure from the rest
of the code.
Given that this makes the array hidden, we can also make the array
constexpr by altering the members slightly. This gets rid of several
static constructor calls related to std::vector and std::function.
Now we don't have heap allocations here that need to occur before the
program can even enter main(). It also has the benefit of saving a
little bit of heap space, but this doesn't matter too much, since the
savings in that regard are pretty tiny.
Based on the `roles` payload in the JWT, the rooms will now give mod permission to Citra Community Moderators. To notify the client of its permissions, a new response, IdJoinSuccessAsMod is added, and there's now a new RoomMember::State called Moderator.
The user would be notified if the message contains "@" followed by the user's nickname or forum username. An alert would be shown, and the icon and message in the status bar would be changed. All notification is only shown if the chat window currently does not have focus.
Also added a connected_notification icon for showing in the status bar.
The ban list is stored in a format so-called CitraRoom-BanList-1 and just first stores username ban list, one entry per line, then an empty line and then store the ip ban list.
To allow for passing moderation errors around without impacting the State, this commit also separates the previous State enum into two enums: State, and Error. The State enum now only contains generic states like disconnected or connected, and the Error enum describes the specific error happened.
citra_qt/multiplayer/{state, message} is changed accordingly.
Displayed username along with nickname (when they are not identical); Requested and displayed user's avatar; Made the dialog bigger for extended names.
Added a few functions to web_backend (GetImage, GetPlain) to support getting data in multiple content-types.
Added a no_avatar icon for users without avatars.
Added verify_backend to load user_data for members. and removed method to generate UID as this is now done server-side.
Added GetUsername function and a "token" param to room_member.
Also added a username to ChatEntry, so that the username can be shown (along with nicknames) in the chat dialog.
These slots are only ever attached to event handling mechanisms within
the class itself, they're never used externally. Because of this, we can
make the functions private.
This also removes redundant usages of the private access specifier.
The previous code could potentially be a compilation issue waiting to
occur, given we forward declare the type for a std::unique_ptr. If the
complete definition of the forward declared type isn't visible in a
translation unit that the class is used in, then it would fail to
compile.
Defaulting the destructor in a cpp file ensures the std::unique_ptr's
destructor is only invoked where its complete type is known.
Because HLE::Source is initialized as an array in the member initializer, it is hard to let it accept the reference on ctor, so it has a second init stage performed by DspHle::Impl::Impl
Hardware testing indicated that FFFFFFFC is the correct mask for all audio formats (mono and stereo PCM8, mono and stereo PCM16, and ADPCM). This fixes broken audio in Luigi's Mansion: Dark Moon and a few other games.
Allows capturing screenshot at the current internal resolution (native for software renderer), but a setting is available to capture it in other resolutions. The screenshot is saved to a single PNG in the current layout.
While admirable as a means to ensure immutability, this has the
unfortunate downside of making the class non-movable. std::move cannot
actually perform a move operation if the provided operand has const data
members (std::move acts as an operation to "slide" resources out of an
object instance). Given Barrier contains move-only types such as
std::mutex, this can lead to confusing error messages if an object ever
contained a Barrier instance and said object was attempted to be moved.
This is also unused and superceded by standard functionality. The
standard library provides std::this_thread::sleep_for(), which provides
a much more flexible interface, as different time units can be used with
it.
This is an old function that's no longer necessary. C++11 introduced
proper threading support to the language and a thread ID can be
retrieved via std::this_thread::get_id() if it's ever needed.
Both member functions assume the passed in target process will not be
null. Instead of making this assumption implicit, we can change the
functions to be references and enforce this at the type-system level.
All usage of GetPointerFromVMA is to recover the pointer that is nulled by changing page type to RasterizerCachedMemory. Our rasterizer cache only works on linear heap and vram, so we can recover the pointer directly by address computation, instead of going through VMA table. Also removed a sanity check pointer!=nullptr in RasterizerMarkRegionCached(RasterizerCachedMemory=>Memory), as now the pointer is never null. The sanity check was added in f2a5a77 (#2797), which was originally necessary during VMA unmapping process, because the function is invloked by VMA after unmapping the page, which in turn invokes back to query the memory, forming a circular dependency. Now the dependency is resolved so the check is not necessary
When yuzu is compiled in release mode this function is unused, however,
when compiled in debug mode, it's used within a LOG_TRACE statement.
This prevents erroneous compilation warnings about an unused function
(that isn't actually totally unused).
They were missed, and Copy is very high in profile here. It doesn't block the GPU,
but it stalls the driver thread. So with our bad GL instructions, this might block quite a while.
Those implementations are quite costly, so there is no need to inline them to the caller.
Ressource deletion is often a performance bug, so in this way, we support to add breakpoints to them.

An old function from Dolphin. This is also unused, and pretty inflexible
when it comes to printing out different data types (for example, one
might not want to print out an array of u8s but a different type
instead. Given we use fmt, there's no need to keep this implementation
of the function around.
This is an unused hold-over from Dolphin that was primarily used to
parse values out of the .ini files. Given we already have libraries that
do this for us, we don't need to keep this around.
Since last commit SharedMemory only reset source memory set on dtor, service should always release the ref as soon as possible to make the reset happen
This is used by svcControlProcessMemory and maps memory as Locked/AliasCode pair.
Also fixed a bug where map didn't apply specified permissions to the alias memory
Storing signed type causes the following behaviour: extractValue can do overflow/negative left shift. Now it only relies on two implementation-defined behaviours (which are almost always defined as we want): unsigned->signed conversion and signed right shift
There is no external use of PhysicalToVirtualAddress any more, so it there is no need to have a generic function that handles all physical regions. Also, the previous APT change makes it possible that linear heap has some regions mapped to old and new VAddr regions at the same time, so we need to check both region and mark cached for the mapped one. RasterizerMarkRegionCached would skip the unmapped one in its loop
* Kernel: reimplement memory management on physical FCRAM
* Kernel/Process: Unmap does not care the source memory permission
What game usually does is after mapping the memory, they reprotect the source memory as no permission to avoid modification there
* Kernel/SharedMemory: zero initialize new-allocated memory
* Process/Thread: zero new TLS entry
* Kernel: fix a bug where code segments memory usage are accumulated twice
It is added to both misc and heap (done inside HeapAlloc), which results a doubled number reported by svcGetProcessInfo. While we are on it, we just merge the three number misc, heap and linear heap usage together, as there is no where they are distinguished.
Question: is TLS page also added to this number?
* Kernel/SharedMemory: add more object info on mapping error
* Process: lower log level; SharedMemory: store phys offset
* VMManager: add helper function to retrieve backing block list for a range
Processes can keep some Thread/Timer object alive while the manager is already destructed, resulting use-after-free in Thread::Stop and Timer::dtor. To resolve this, the manager objects should be destructed after all related object destructed.
Fixes a bug where quiting citra causes crash while the game is using a Timer.
Fix a warning where class definition and forward declaration mismatch. CodeSet is a kernel object and have ctor/dtor/private members like others, so in convention it should be a class
To obtain the data, the LLEd mii selector of system version 11.8.0 was used.
In AppletManager::GlanceParameter, the following code was added to write the returned buffer data to a file:
if (parameter.buffer.size() == 132) {
std::u16string name(10, '\0');
std::memcpy(name.data(), parameter.buffer.data() + 0x26, 10 * sizeof(u16));
name = std::u16string(name.data());
FileUtil::IOFile file{fmt::format("{}.mii", Common::UTF16ToUTF8(name)), "wb"};
file.WriteBytes(parameter.buffer.data(), parameter.buffer.size());
}
Then "xxd -i" was used on the file to convert it to a hex array.
* FileSys/DelayGenerator: add missing #include and virtual dtor
Added the needed include so that it won't cause error if another file includes this without including the depended files
Deleting a virtual class via base type without virtual dtor is UB, which happens inFileBackend.
* FileSys/DelayGenerator: move function definition into cpp file/n/nTo avoid generating vtable in all units that includes the header file
* filesys/delay_generator: rearrange #include
tr() will not function properly on static/global data like this, as the
object is only ever constructed once, so the strings won't translate if
the language is changed without restarting the program, which is
undesirable. Instead we can just turn the map into a plain old function
that maps the values to their equivalent strings. This is also lessens
the memory allocated, since it's only allocating memory for the strings
themselves, and not an encompassing map as well.
This is more localized to what we want to enforce directory-wise with
the project. CMAKE_SOURCE_DIR indicates the root of the source tree, but
this would cause the wrong behavior if someone included yuzu as part of
a larger buildsystem (for whatever reason). Instead, we want to use the
directory where the "project(yuzu)" command was declared as the root
path reference.
These should be initialized to deterministic values so it's easier to
catch improper behavior, as it'll always be reproducable, instead of
performing uninitialized reads.
These are only used within this class, so we can make them private to
keep their use contained. This also gets rid of the pre-Qt5 'slot'
identifier, since Qt 5's connection syntax doesn't require a function to
be declared a slot anymore.
This gets rid of an unnecessary type conversion. We can just use the
regular QStringLiteral to already format the string as the type
setWindowTitle accepts instead of converting from a std::string
instance.
Everything from here is completely unused and also written with the
notion of supporting 32-bit architecture variants in mind. Given the
Switch itself is on a 64-bit architecture, we won't be supporting 32-bit
architectures. If we need specific allocation functions in the future,
it's likely more worthwhile to new functions for that purpose.
We already ignore them on listing devices. We should do the same when selecting devices. This fix a crash when opening a specific device while there is a null device in the list
* Initial implementation

Keeps the definition constrained to the citra_qt target and prevents
polluting anything else in the same directory (should that ever happen).
It also keeps it consistent with how the USE_DISCORD_PRESENCE definition
is introduced below it.
Now that all external dependencies are hidden, we can remove
json-headers from the publically linked libraries, as the use of this
library is now completely hidden from external users of the web_service
library. We can also make the web_services library private as well,
considering it's not a requirement. If a library needs to link in
web_service, it should be done explicitly -- not via indirect linking.
Like with TelemetryJson, we can make the implementation details private
and avoid the need to expose httplib to external libraries that need to
use the Client class.
Users of the web_service library shouldn't need to care about an
external library like json.h. However, given it's exposed in our
interface, this requires that other libraries publicly link in the JSON
library. We can do better.
By using the PImpl idiom, we can hide this dependency in the cpp file
and remove the need to link that library in altogether.
Taking them by const reference isn't advisable here, because it means
the std::move calls were doing nothing and we were always copying the
std::string instances.
Two functional change:
QueryProcessMemory uses the process passed from handle instead current_process
Thread::Stop() uses TLS from owner_process instead of current_process
This should be using the process instance retrieved within the function,
and not g_current_process, otherwise this is potentially comparing
iterators from unrelated vma_map instances (which is undefined
behavior).
Lets us keep the generic portions of the compatibility list code
together, and allows us to introduce a type alias that makes it so we
don't need to type out a very long type declaration anymore, making the
immediate readability of some code better.
This has gotten sufficiently large enough to warrant moving it to its
own source files. Especially given it dumps the file_sys headers around
code that doesn't use it for the most part.
This'll also make it easier to introduce a type alias for the
compatibility list, so a large unordered_map type declaration doesn't
need to be specified all the time (we don't want to propagate the
game_list_p.h include via the main game_list.h header).
Depending on whether or not USE_DISCORD_PRESENCE is defined, the "state"
parameter can be used or unused. If USE_DISCORD_PRESENCE is not defined,
the parameter will be considered unused, which can lead to compiler
warnings. So, we can explicitly mark it with [[maybe_unused]] to inform
the compiler that this is intentional.
We can utilize QStringList's join() function to perform all of the
appending in a single function call.
While we're at it, make the extension list a single translatable string
and add a disambiguation comment to explain to translators what %1
actually is.

This adds a Game List configuration group box which is similar to yuzu's, with features including icon size setting, row 1/2 text, and ability to hide invalid titles (those without a valid SMDH). I also added a UI tab and moved the language and theme settings there.
The real console can't launch an Application directly from within another Application so it has to go through the Home Menu. We do not have such limitation and can directly launch the requested title.
operator+ for std::string creates an entirely new string, which is kind
of unnecessary here if we just want to append a null terminator to the
existing one.
Reduces the total amount of potential allocations that need to be done
in the logging path.
Placing the array wholesale into the header places a copy of the whole
array into every translation unit that uses the data, which is wasteful.
Particularly given that this array is referenced from three different
translation units.
This also changes the array to contain pairs of const char*, rather than
QString instances. This way, the string data is able to be fixed into
the read-only segment of the program, as well as eliminate static
constructors/heap allocation immediately on program start.
