* Asserts: break/crash program, fit to style guide; log.h->assert.harchshift2015-02-111-8/+6
| | | | | | | 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.
* Scheduler refactor Pt. 1Kevin Hartman2015-02-101-185/+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.
* Kernel: Stop creating useless Handles during object creationYuri Kunde Schlesner2015-02-021-8/+0
| | | | | They're finally unnecessary, and will stop cluttering the application's handle table.
* Kernel: Make WaitObjects share ownership of Threads waiting on themYuri Kunde Schlesner2015-02-021-0/+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.)
* Explicitly instantiate constructors/destructors for Kernel objectsYuri Kunde Schlesner2015-02-021-2/+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.)

| | | | 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.
* Common: Clean up ThreadQueueListYuri Kunde Schlesner2015-01-071-1/+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.
* Kernel: New handle managerYuri Kunde Schlesner2014-12-281-1/+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.

* HLE: Revamp error handling throrough the HLE codeYuri Kunde Schlesner2014-11-241-21/+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.
