* kernel: Eliminate kernel global stateLioncash2018-08-281-3/+3
| | | | | | | | | | | | | | | | | | | | | | 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.
* kernel: Move object class to its own source filesLioncash2018-08-011-1/+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.

| * kernel: Remove unused object_address_table.cpp/.hLioncash2018-07-311-1/+0
| | | | | | | | | | | | These source files were entirely unused throughout the rest of the codebase. This also has the benefit of getting rid of a global variable as well.
* | kernel: Remove unnecessary includesLioncash2018-07-311-0/+4
|/ | | | | Removes unnecessary direct dependencies in some headers and also gets rid of indirect dependencies that were being relied on to be included.
* mutex: Pass SharedPtr to GetHighestPriorityMutexWaitingThread() by referenceLioncash2018-07-231-1/+1
| | | | | The pointed to thread's members are simply observed in this case, so we don't need to copy it here.
* thread: Convert ThreadStatus into an enum classLioncash2018-07-191-3/+3
| | | | | Makes the thread status strongly typed, so implicit conversions can't happen. It also makes it easier to catch mistakes at compile time.

* Mutex: Do not assert when the mutex waiting threads list isn't empty on ↵Subv2018-05-201-1/+0
| | | | | | mutex release. A thread may own multiple mutexes at the same time, and only release one of them while other threads are waiting for the other mutexes.
* Kernel: Implemented mutex priority inheritance.Subv2018-04-231-8/+31
| | | | | | | 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.

* Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.Subv2018-04-201-0/+94
| | | | | | | | | | 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.

* Kernel/Mutex: Implemented priority inheritance.Subv2017-01-041-13/+45
| | | | | | | 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.

* Kernel/Synch: Do not attempt a reschedule on every syscall.Subv2017-01-041-0/+1
| | | | Not all syscalls should cause reschedules, this commit attempts to remedy that, however, it still does not cover all cases.

* Asserts: break/crash program, fit to style guide; log.h->assert.harchshift2015-02-101-1/+1
| | | | | | | 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.

* Kernel: Stop creating useless Handles during object creationYuri Kunde Schlesner2015-02-021-4/+2
| | | | | They're finally unnecessary, and will stop cluttering the application's handle table.
* Kernel: Make WaitObjects share ownership of Threads waiting on themYuri Kunde Schlesner2015-02-021-2/+2
| | | | | | | | | | | | | | | | 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.)
* Explicitly instantiate constructors/destructors for Kernel objectsYuri Kunde Schlesner2015-02-021-0/+3
| | | | | | 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.)
