2018-09-18arm_interface: Remove ARM11-isms from the CPU interfaceLioncash1-2/+2
This modifies the CPU interface to more accurately match an AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods don't even make sense to keep around for this interface, as Adv Simd is used, rather than the VFP in the primary execution state. This is essentially a modernization change that should have occurred from the get-go.

2018-09-12kernel/errors: Correct error codes for invalid thread priority and invalid processor IDLioncash1-2/+2
2018-08-31core/core: Replace includes with forward declarations where applicableLioncash1-1/+2
The follow-up to e2457418dae19b889b2ad85255bb95d4cd0e4bff, which replaces most of the includes in the core header with forward declarations. This makes it so that if any of the headers the core header was previously including change, then no one will need to rebuild the bulk of the core, due to core.h being quite a prevalent inclusion. This should make turnaround for changes much faster for developers.
2018-08-29kernel: Eliminate kernel global stateLioncash1-101/+18
As means to pave the way for getting rid of global state within core, This eliminates kernel global state by removing all globals. Instead this introduces a KernelCore class which acts as a kernel instance. This instance lives in the System class, which keeps its lifetime contained to the lifetime of the System class. This also forces the kernel types to actually interact with the main kernel instance itself instead of having transient kernel state placed all over several translation units, keeping everything together. It also has a nice consequence of making dependencies much more explicit. This also makes our initialization a tad bit more correct. Previously we were creating a kernel process before the actual kernel was initialized, which doesn't really make much sense. The KernelCore class itself follows the PImpl idiom, which allows keeping all the implementation details sealed away from everything else, which forces the use of the exposed API and allows us to avoid any unnecessary inclusions within the main kernel header.
2018-08-25core: Namespace all code in the arm subdirectory under the Core namespaceLioncash1-2/+2
Gets all of these types and interfaces out of the global namespace.
2018-08-13Core::CoreTiming: add UnscheduleEventThreadsafeB3n301-1/+1
2018-08-13Kernel/Threads: Lock the HLE mutex when executing the wakeup callback.Subv1-0/+5
Another thread might be in the middle of a reschedule, thus altering the state of the schedulers.
2018-08-13Kernel/Thread: Always use the threadsafe option when scheduling wakeups.Subv1-2/+4
WakeAfterDelay might be called from any host thread, so err on the side of caution and use the thread-safe CoreTiming::ScheduleEventThreadsafe. Note that CoreTiming is still far from thread-safe, there may be more things we have to work on for it to be up to par with what we want.
2018-08-12Kernel/Mutex: Don't duplicate threads in the mutex waiter list.Subv1-0/+21
Exit from AddMutexWaiter early if the thread is already waiting for a mutex owned by the owner thread. This accounts for the possibility of a thread that is waiting on a condition variable being awakened twice in a row. Also added more validation asserts. This should fix one of the random crashes in Breath Of The Wild.
2018-08-04kernel/thread: Fix potential crashes introduced in 26de4bb521b1ace7af76eff4f6956cb23ac0d58cLioncash1-0/+11
This amends cases where crashes can occur that were missed due to the odd way the previous code was set up (using 3DS memory regions that don't exist).
2018-08-03core/memory: Get rid of 3DS leftoversLioncash1-31/+2
Removes leftover code from citra that isn't needed.
2018-08-02kernel/thread: Make GetFreeThreadLocalSlot()'s loop indices size_tLioncash1-8/+5
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.
2018-08-02kernel/thread: Make GetFreeThreadLocalSlot() reference parameter a const referenceLioncash1-1/+2
This function only reads the data being referenced, it doesn't modify it, so we can turn the reference into a const reference.
2018-08-02kernel/thread: Make GetFreeThreadLocalSlot() internally linkedLioncash1-1/+1
This function isn't used outside of this translation unit, so we can make it internally linked.
2018-08-02kernel: Move object class to its own source filesLioncash1-1/+1
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.
2018-07-31kernel: Remove unnecessary includesLioncash1-2/+4
Removes unnecessary direct dependencies in some headers and also gets rid of indirect dependencies that were being relied on to be included.

2018-07-21CPU: Save and restore the TPIDR_EL0 system register on every context switch.Subv1-0/+1
Note that there's currently a dynarmic bug preventing this register from being written.
2018-07-20thread: Convert ThreadStatus into an enum classLioncash1-24/+23
Makes the thread status strongly typed, so implicit conversions can't happen. It also makes it easier to catch mistakes at compile time.
2018-07-19core/memory, core/hle/kernel: Use std::move where applicableLioncash1-1/+1
Avoids pointless copies
2018-07-19core: Don't construct instance of Core::System, just to access its live instanceLioncash1-6/+6
This would result in a lot of allocations and related object construction, just to toss it all away immediately after the call. These are definitely not intentional, and it was intended that all of these should have been accessing the static function GetInstance() through the name itself, not constructed instances.

2018-06-02Kernel/Threads: A thread waking up by timeout from a WaitProcessWideKey may already have an assigned lock owner.Subv1-2/+5
This situation may happen like so: Thread 1 with low priority calls WaitProcessWideKey with timeout. Thread 2 with high priority calls WaitProcessWideKey without timeout. Thread 3 calls SignalProcessWideKey - Thread 2 acquires the lock and awakens. - Thread 1 can't acquire the lock and is put to sleep with the lock owner being Thread 2. Thread 1's timeout expires, with the lock owner still being set to Thread 2.

2018-04-23Kernel: Implemented mutex priority inheritance.Subv1-2/+39
Verified with a hwtest and implemented based on reverse engineering. Thread A's priority will get bumped to the highest priority among all the threads that are waiting for a mutex that A holds. Once A releases the mutex and ownership is transferred to B, A's priority will return to normal and B's priority will be bumped.

2018-04-21Kernel: Remove old and unused Mutex code.Subv1-3/+0
2018-04-21Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.Subv1-1/+12
Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case. Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock. TODO: * Fix svcWaitProcessWideKey * Fix svcSignalProcessWideKey * Remove the Mutex class.

Ported from citra PR #3091 The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch. This change is enough to prevent Puyo Puyo Tetris's main thread starvation.

2017-09-28Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken.Subv1-3/+10
This change makes for a clearer (less confusing) path of execution in the scheduler, now the code to execute when a thread awakes is closer to the code that puts the thread to sleep (WaitSynch1, WaitSynchN). It also allows us to implement the special wake up behavior of ReplyAndReceive without hacking up WaitObject::WakeupAllWaitingThreads. If savestates are desired in the future, we can change this implementation to one similar to the CoreTiming event system, where we first register the callback functions at startup and assign their identifiers to the Thread callback variable instead of directly assigning a lambda to the wake up callback variable.
2017-09-27Kernel/Thread: Allow specifying which process a thread belongs to when creating it.Subv1-8/+9
Don't automatically assume that Thread::Create will only be called when the parent process is currently scheduled. This assumption will be broken when applets or system modules are loaded.
2017-09-24memory: Add GetCurrentPageTable/SetCurrentPageTableMerryMage1-7/+4
Don't expose Memory::current_page_table as a global.
2017-09-15Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process.Subv1-1/+3
We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.
2017-09-10Kernel/Memory: Switch the current page table when a new process is scheduled.Subv1-0/+10
2017-08-22Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.Subv1-5/+1
This is necessary for loading multiple processes at the same time. The main thread will be automatically scheduled when necessary once the scheduler runs.
2017-06-19ResultVal: Remove MoveFrom()Yuri Kunde Schlesner1-2/+2
Replace it with std::move(result_val).Unwrap(), or Foo().Unwrap() in case you already have an rvalue.

2017-01-06Kernel: Don't attempt to yield execution in SleepThread(0) if there are no available threads to run.Subv1-0/+4
With this we avoid an useless temporary deschedule of the current thread.
2017-01-05Kernel: Remove some unused functions.Subv1-23/+0
2017-01-05Kernel: Removed the priority boost code for starved threads.Subv1-27/+0
After hwtesting and reverse engineering the kernel, it was found that the CTROS scheduler performs no priority boosting for threads like this, although some other forms of scheduling priority-starved threads might take place. For example, it was found that hardware interrupts might cause low-priority threads to run if the CPU is preempted in the middle of an SVC handler that deschedules the current (high priority) thread before scheduling it again.
2017-01-05Kernel: Add some asserts to enforce the invariants in the scheduler.Subv1-2/+5
2017-01-05Kernel: Remove Thread::wait_objects_index and use wait_objects to hold all the objects that a thread is waiting on.Subv1-0/+5
2017-01-04Kernel: Use different thread statuses when a thread calls WaitSynchronization1 and WaitSynchronizationN with wait_all = true.Subv1-4/+7
This commit removes the overly general THREADSTATUS_WAIT_SYNCH and replaces it with two more granular statuses: THREADSTATUS_WAIT_SYNCH_ANY when a thread waits on objects via WaitSynchronization1 or WaitSynchronizationN with wait_all = false. THREADSTATUS_WAIT_SYNCH_ALL when a thread waits on objects via WaitSynchronizationN with wait_all = true.
2017-01-04Kernel/Mutex: Propagate thread priority changes to other threads inheriting the priority via mutexesSubv1-4/+17
2017-01-04Kernel/Mutex: Implemented priority inheritance.Subv1-3/+3
The implementation is based on reverse engineering of the 3DS's kernel. A mutex holder's priority will be temporarily boosted to the best priority among any threads that want to acquire any of its held mutexes. When the holder releases the mutex, it's priority will be boosted to the best priority among the threads that want to acquire any of its remaining held mutexes.
2017-01-04Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter.Subv1-3/+3
This will be useful when implementing mutex priority inheritance.

2016-12-10Properly remove a thread from its wait_objects' waitlist when it is awoken by a timeout.Subv1-0/+4
2016-12-04Threading: Reworked the way our scheduler works.Subv1-94/+3
Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then. The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback. This new implementation is based off reverse-engineering of the real kernel. See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries. This is consistent with what the real kernel does.

2015-07-17Ensure all kernel objects are released during shutdownYuri Kunde Schlesner1-7/+14
This commit fixes several kernel object leaks. The most severe of them was threads not being removed from the private handle table used for CoreTiming events. This resulted in Threads never being released, which in turn held references to Process, causing CodeSets to never be freed when loading other applications.

Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time) As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing) Also removed some GEKKO cruft.
2015-02-10Scheduler refactor Pt. 1Kevin Hartman1-185/+175
* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid for a thread at any given point in the system. * Removes dead code from thread.cpp. * Moves the implementation of resetting a ThreadContext to the corresponding core's implementation. Other changes: * Fixed comments in arm interfaces. * Updated comments in thread.cpp * Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp. * Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.
2015-02-02Kernel: Stop creating useless Handles during object creationYuri Kunde Schlesner1-8/+0
They're finally unnecessary, and will stop cluttering the application's handle table.
2015-02-02Kernel: Make WaitObjects share ownership of Threads waiting on themYuri Kunde Schlesner1-0/+3
During normal operation, a thread waiting on an WaitObject and the object hold mutual references to each other for the duration of the wait. If a process is forcefully terminated (The CTR kernel has a SVC to do this, TerminateProcess, though no equivalent exists for threads.) its threads would also be stopped and destroyed, leaving dangling pointers in the WaitObjects. The solution is to simply have the Thread remove itself from WaitObjects when it is stopped. The vector of Threads in WaitObject has also been changed to hold SharedPtrs, just in case. (Better to have a reference cycle than a crash.)
2015-02-02Explicitly instantiate constructors/destructors for Kernel objectsYuri Kunde Schlesner1-2/+2
This should speed up compile times a bit, as well as enable more liberal use of forward declarations. (Due to SharedPtr not trying to emit the destructor anymore.)

2015-01-09SVC: Fixed SleepThread.Subv1-8/+32
It will now properly wait the specified number of nanoseconds and then wake up the thread.
2015-01-08Threads: Use a dummy idle thread when no other are ready.Subv1-1/+22
This thread will not actually execute instructions, it will only advance the timing/events and try to yield immediately to the next ready thread, if there aren't any ready threads then it will be rescheduled and start its job again.
2015-01-07Common: Clean up ThreadQueueListYuri Kunde Schlesner1-1/+1
Replace all the C-style complicated buffer management with a std::deque. In addition to making the code easier to understand it also adds support for non-POD IdTypes. Also clean the rest of the code to follow our code style.
2014-12-28Kernel: New handle managerYuri Kunde Schlesner1-1/+2
This handle manager more closely mirrors the behaviour of the CTR-OS one. In addition object ref-counts and support for DuplicateHandle have been added. Note that support for DuplicateHandle is still experimental, since parts of the kernel still use Handles internally, which will likely cause troubles if two different handles to the same object are used to e.g. wait on a synchronization primitive.

2014-12-04Threads: Implemented a sequential thread idSubv1-3/+13
2014-12-04SVC: Implemented GetThreadId.Subv1-0/+16
For now threads are using their Handle value as their Id, it should not really cause any problems because Handle values are unique in Citra, but it should be changed. I left a ToDo there because this is not correct behavior as per hardware.

2014-11-24HLE: Revamp error handling throrough the HLE codeYuri Kunde Schlesner1-21/+30
All service calls in the CTR OS return result codes indicating the success or failure of the call. Previous to this commit, Citra's HLE emulation of services and the kernel universally either ignored errors or returned dummy -1 error codes. This commit makes an initial effort to provide an infrastructure for error reporting and propagation which can be use going forward to make HLE calls accurately return errors as the original system. A few parts of the code have been updated to use the new system where applicable. One part of this effort is the definition of the `ResultCode` type, which provides facilities for constructing and parsing error codes in the structured format used by the CTR. The `ResultVal` type builds on `ResultCode` by providing a container for values returned by function that can report errors. It enforces that correct error checking will be done on function returns by preventing the use of the return value if the function returned an error code. Currently this change is mostly internal since errors are still suppressed on the ARM<->HLE border, as a temporary compatibility hack. As functionality is implemented and tested this hack can be eventually removed.
