Subv 8634b8cb83 Threading: Reworked the way our scheduler works.
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.

Yuri Kunde Schlesner 84fbbe2629 Use negative priorities to avoid special-casing the self-include 2016-09-21 00:15:56 -07:00
Emmanuel Gil Peyrot ebdae19fd2 Remove empty newlines in #include blocks.
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Subv 29032ce9b6 SVC: Fixed ArbitrateAddress to behave as it does on hardware.
This was verified with hwtests that i plan to upload later on.

Yuri Kunde Schlesner 7ada357b2d Memmap: Re-organize memory function in two files

configuring the address space
mem_map.cpp/h contains higher-level definitions related to configuring
the address space accoording to the kernel and allocating memory.

Yuri Kunde Schlesner 88a4a808c6 Kernel: Stop creating useless Handles during object creation
They're finally unnecessary, and will stop cluttering the application's
handle table.

Yuri Kunde Schlesner 7725256f64 Explicitly instantiate constructors/destructors for Kernel objects
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.)

Yuri Kunde Schlesner 7e2903cb74 Kernel: New handle manager
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.

Yuri Kunde Schlesner c2588403c0 HLE: Revamp error handling throrough the HLE code
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.

Lioncash 98fa3f7cba Core: Alter the kernel string functions to use std::string instead of const char*.
Most functions already operate on std::strings. This also removes the need to manually null terminate thread names.
