This causes a reference cycle because ServerPort also holds a shared pointer to SessionRequestHandler (inherited by ServiceFrameworkBase). Given that the member port is never used in ServiceFrameworkBase, we can simply remove it. The port object is kept alive by ServiceManager|KernelSystem::named_ports -> ClientPort -> ServerPort
Services can hold kernel objects and do cleanup upon destruction, so we need to keep the kernel alive longer. The new order approximnately resembles the reverse construction order. I will revisit the ordering issue and make it less error-prone after global state cleanup
When making the initial implementation, I forgot to add the series variable to the AmiiboConfig struct.
With this PR it is added and many of the AmiiboConfig fields get their proper values now.
The loading of the Amiibo data that is added here has been hwtested.
This fixes Amiibos in Yoshis Woolly World, Smash (partially) and probably other games too.
* 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
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.
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.
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.
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)
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.
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.
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.
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).

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
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.

* Add more state checking, remove unneeded include
* Minor changes
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.
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).
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.
* Core: pass down Core::System reference to all services
This has to be done at once due to unified interface used by HLE/LLE switcher
* apt: eliminate Core::System::GetInstance
* gpu_gsp: eliminate Core::System::GetInstance in service
* hid: eliminate Core::System::GetInstance
* nwm: eliminate Core::System::GetInstance
* err_f: eliminate Core::System::GetInstance
These functions are pretty much identical to BeginImportProgram and EndImportProgram.
We don't need to do anything special in EndImportProgramWithoutCommit and CommitImportPrograms because we don't need to implement the two-phase title installation that the 3DS uses to prevent corruption of the title.db.
FS subfiles are created with File::OpenSubFile, they have a start offset that must be added to all read/write operations.
The implementation in this commit is done using a new FileBackend that wraps the FS::File along with the start offset.
Frame advancing is a commonly used TAS feature which basically means running the game frame by frame. TASers use this feature to press exact buttons at the exact frames. This commit added frame advancing to the framelimiter and two actions to the Movie menu. The default hotkey is `\` for advancing frames, and `Ctrl+A` for toggling frame advancing. The `Advance Frame` hotkey would automatically enable frame advancing if not already enabled.
boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is),
takes its parameter by const reference. Given that, it means that this
std::move doesn't actually do anything other than obscure what the
function's actual behavior is, so we can remove this. To clarify, this
would only do something if the parameter was either taking its argument
by value, by non-const ref, or by rvalue-reference.
This adds a clock init time field to the CTM header. The clock settings would be overridden when playing a movie. And when recording a movie, if the clock is set to System Time, it would be set to fixed init time at the current moment as well. In this way this keeps consistency with the RNG even if the user does just no setting.
This can just be a regular function, getting rid of the need to also
explicitly undef the define at the end of the file. Given FuncReturn()
was already converted into a function, it's #undef can also be removed.
Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.
We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
There were a few places where nested namespace specifiers weren't being
used where they could be within the service code. This amends that to
make the namespacing a tiny bit more compact.
While likely very uncommon, this sanitizes the input and does nothing in
the event of the length being equal to or less than zero, avoiding
constructing a std::string when there's no need to. It also avoids an
out-of-memory scenario, as a negative value would wrap around to its
equivalent unsigned representation in std::string's constructor.
e.g. If someone was silly and a length of -1 was specified, this would
make a string with a length of 0xFFFFFFFFFFFFFFFF on a 64-bit platform,
which will obviously eventually fail due to the allocation being way too
large.
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class
which is within the Kernel namespace.

Given these functions aren't intended to be used frequently, there's no
need to keep the std::string instances allocated for the whole lifetime
of the program. It's just a waste of memory.
Despite being covered by a global mutex, we should still ensure that the
class handles its reference counts properly. This avoids potential
shenanigans when it comes to data races.
Given this is the root object that drives quite a bit of the kernel
object hierarchy, ensuring we always have the correct behavior (and no
races) is a good thing.
Shared fonts is no different from any other system archives, and there is not really any point to make a separate status for it. This also fixes the incorrect error message that was introduced when I made the UI text improvements.
* Add setting to switch between a fixed start time and the system time
Add clock settings to SDL
Make clock configureable in qt
Add a SharedPage handler class
Init shared_page_handler for tests
Rather than having to type out the full std::map type signature, we can
just use a straightforward alias. While we're at it, rename
GetBreakpointList to GetBreakpointMap, which makes the name more
accurate. We can also get rid of unnecessary u64 static_casts, since
VAddr is an alias for a u64.
…class
Makes the global a member of the RendererBase class. We also change this
to be a reference. Passing any form of null pointer to these functions
is incorrect entirely, especially given the code itself assumes that the
pointer would always be in a valid state.
This also makes it easier to follow the lifecycle of instances being
used, as we explicitly interact the renderer with the rasterizer, rather
than it just operating on a global pointer.
* kernel/event: Make data members private
Instead we can simply provide accessors to the required data instead of
giving external read/write access to the variables directly.
* fix compile error
* client_port: Make all data members private
These members don't need to be entirely exposed, we can instead expose
an API to operate on them without directly needing to mutate them
We can also guard against overflow/API misuse this way as well, given
active_sessions is an unsigned value.
* make the condition an assert
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.
- Can be used in either DynCom or Dynarmic mode
- Added support for threads
- Proper support for FPU registers
- Fix for NibbleToHex conversion that used to produce false error codes
- Fix for clang-format failing under Windows
* NWM_UDS: use sizeof(<var being used>) instead of hard-coded type
Intend to fix#4090.
` node_map.node.second` type was changed to `u16` in #3985. However the type change wasn't reflected here. Should have used variable name instead to automatically do type change
* NWM_UDS: ... and also the node.first one
* NWM_UDS: ... and here
* Network: bump version because we changed UDS packet layout
* Update nwm_uds.cpp
Avoids using a u32 to compare against a range of size_t, which can be a
source of warnings. While we're at it, compress a std::tie into a
structured binding.
Gets rid of the need to hardcode the type in multiple places. This will
now be deduced automatically, based off the elements in the container
being provided to the algorithm.
