Removes even more usages of the global system instance, trimming away
more dependencies on global variables and making them explicit in the
interface.

Over the course of the changes to the kernel code, a few includes are no
longer necessary, particularly with the change over to std::shared_ptr
from Boost's intrusive_ptr.

kernel objects. (#3154)
* kernel: Replace usage of boost::intrusive_ptr with std::shared_ptr for kernel objects.
- See https://github.com/citra-emu/citra/pull/4710 for details.

The kernel allows restricting the total size of the handle table through
the process capability descriptors. Until now, this functionality wasn't
hooked up. With this, the process handle tables become properly restricted.
In the case of metadata-less executables, the handle table will assume
the maximum size is requested, preserving the behavior that existed
before these changes.
|
|
Directly initializes members where applicable.
|
|
We've had the old kernel capability parser from Citra, however, this is
unused code and doesn't actually map to how the kernel on the Switch
does it. This introduces the basic functional skeleton for parsing
process capabilities.
|
|
Allows a process to register the resource limit as part of its handle
table.
|
|
These don't depend on class state, and are effectively implementation
details, so they can go into the cpp file .
|
|
The previous handle table size is a holdover from Citra. The actual
handle table construct on Horizon only allows for a maximum of 1024
entries.
|
|
We don't need to potentially inline the teardown logic of all of the
handle instances.

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.

This replaces the lingering 3DS constant with the proper one, and
utilizes it within HandleTable's Create() member function.
|
|
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.
