2018-11-29kernel: Divide Event into ReadableEvent and WritableEventZach Hilman1-53/+0
More hardware accurate. On the actual system, there is a differentiation between the signaler and signalee, they form a client/server relationship much like ServerPort and ClientPort.
2018-08-29kernel: Eliminate kernel global stateLioncash1-4/+4
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.
2018-08-02kernel: 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/+0
Removes unnecessary direct dependencies in some headers and also gets rid of indirect dependencies that were being relied on to be included.
2018-01-21Format: Run the new clang format on everythingJames Rowe1-1/+1
2017-01-05Kernel: Implemented Pulse event and timers.Subv1-7/+8
Closes #1904
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.
2016-11-19Kernel/Events: Log an error when trying to create Pulse events and timers.Subv1-0/+5
Related to #1904
2016-09-21Use negative priorities to avoid special-casing the self-includeYuri Kunde Schlesner1-1/+1
2016-09-21Remove empty newlines in #include blocks.Emmanuel Gil Peyrot1-3/+1
This makes clang-format useful on those. Also add a bunch of forgotten transitive includes, which otherwise prevented compilation.

2015-05-07Common: Remove common.hYuri Kunde Schlesner1-1/+1
2015-02-11Asserts: break/crash program, fit to style guide; log.h->assert.harchshift1-1/+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.
2015-02-02Kernel: Stop creating useless Handles during object creationYuri Kunde Schlesner1-4/+2
They're finally unnecessary, and will stop cluttering the application's handle table.
2015-02-02Explicitly instantiate constructors/destructors for Kernel objectsYuri Kunde Schlesner1-0/+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.)

2015-01-22WaitObject: Renamed "Wait" to "ShouldWait", made "ShouldWait" and "Acquire" pure virtual.bunnei1-1/+1

- Separate wait checking from waiting the current thread - Resume thread when wait_all=true only if all objects are available at once - Set output to correct wait object index when there are duplicate handles

2015-01-09Thread: Reduce use of Handles and move some funcs to inside the class.Yuri Kunde Schlesner1-3/+5
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.

2014-11-24HLE: Revamp error handling throrough the HLE codeYuri Kunde Schlesner1-19/+19
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.

This was automated using `clang-modernize`.
2014-08-18Core: Alter the kernel string functions to use std::string instead of const char*.Lioncash1-2/+2
Most functions already operate on std::strings. This also removes the need to manually null terminate thread names.
