Since C++17, the introduction of deduction guides for locking facilities
means that we no longer need to hardcode the mutex type into the locks
themselves, making it easier to switch mutex types, should it ever be
necessary in the future.
This reduces the boilerplate that services have to write out the current thread explicitly. Using current thread instead of client thread is also semantically incorrect, and will be a problem when we implement multicore (at which time there will be multiple current threads)
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.
