Lioncash 2de2bb980e kernel/physical_core: Make use of std::unique_ptr
shared_ptr was used in 2d1984c20c due to a
misunderstanding of how the language generates move constructors and
move assignment operators.

If a destructor is user-provided, then the compiler won't generate the
move constructor and move assignment operators by default--they must be
explicitly opted into.

The reason for the compilation errors is due to the fact that the
language will fall back to attempting to use the copy constructor/copy
assignment operators if the respective move constructor or move
assignment operator is unavailable.

Given that we explicitly opt into them now, the the move constructor and
move assignment operators will be generated as expected.

Lioncash 51927bc9dc kernel/physical_core: Remove unused kernel reference member variable
This isn't used within the class, so it can be removed to simplify the
overall interface.

While we're in the same area, we can simplify a unique_ptr reset() call.

Markus Wick c76ffa5019 core/kernel: Fix GetTotalPhysicalMemoryUsed.
module._memory was already moved over to a new shared_ptr.
So code_memory_size was not increased at all.

This lowers the heap space and so saves a bit of memory, usually between 50 to 100 MB.

This fixes a regression of c0a01f3adc

Fernando Sahmkow 22c6b9fab2 Kernel: Correct behavior of Address Arbiter threads. (#3165)
* Kernel: Correct behavior of Address Arbiter threads.

This corrects arbitration threads to behave just like in Horizon OS.
They are added into a container and released according to what priority
they had when added. Horizon OS does not reorder them if their priority
changes.

* Kernel: Address Feedback.

Lioncash c3e43c7e81 kernel: Remove unnecessary includes
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.
2019-12-07 22:37:05 -05:00
Lioncash 67b8265bd6 kernel/svc: Provide implementations for svcDumpInfo/svcDumpInfoNew
These are fairly trivial to implement, we can just do nothing. This also
provides a spot for us to potentially dump out any relevant info in the
future (e.g. for debugging purposes with homebrew, etc).

While we're at it, we can also correct the names of both of these
supervisor calls.

Fernando Sahmkow 40cd4df584 CpuCore: Clear exclusive state after doing a run in dynarmic.
This commit corrects an error in which a Core could remain with an
exclusive state after running, leaving space for possible race
conditions between changing cores.

bunnei c3d3b173d3 kernel: Implement a more accurate IPC dispatch. 2019-11-28 12:01:53 -05:00
Lioncash e7e939104b core/memory; Migrate over SetCurrentPageTable() to the Memory class
Now that literally every other API function is converted over to the
Memory class, we can just move the file-local page table into the Memory
implementation class, finally getting rid of global state within the
memory code.
2019-11-26 21:55:39 -05:00
Lioncash e4c381b885 core/memory: Migrate over Write{8, 16, 32, 64, Block} to the Memory class
The Write functions are used slightly less than the Read functions,
which make these a bit nicer to move over.

The only adjustments we really need to make here are to Dynarmic's
exclusive monitor instance. We need to keep a reference to the currently
active memory instance to perform exclusive read/write operations.
2019-11-26 21:55:39 -05:00
Lioncash b05bfc6036 core/memory: Migrate over Read{8, 16, 32, 64, Block} to the Memory class
With all of the trivial parts of the memory interface moved over, we can
get right into moving over the bits that are used.

Note that this does require the use of GetInstance from the global
system instance to be used within hle_ipc.cpp and the gdbstub. This is
fine for the time being, as they both already rely on the global system
instance in other functions. These will be removed in a change directed
at both of these respectively.

For now, it's sufficient, as it still accomplishes the goal of
de-globalizing the memory code.
2019-11-26 21:55:39 -05:00
Lioncash b2165c6b35 core/memory: Migrate over ReadCString() to the Memory class
This only had one usage spot, so this is fairly straightforward to
convert over.
2019-11-26 21:55:38 -05:00
Lioncash 3f08e8d8d4 core/memory: Migrate over GetPointer()
With all of the interfaces ready for migration, it's trivial to migrate
over GetPointer().
2019-11-26 21:55:38 -05:00
Lioncash 536fc7f0ea core: Prepare various classes for memory read/write migration
Amends a few interfaces to be able to handle the migration over to the
new Memory class by passing the class by reference as a function
parameter where necessary.

Notably, within the filesystem services, this eliminates two ReadBlock()
calls by using the helper functions of HLERequestContext to do that for
us.
2019-11-26 21:55:37 -05:00
Lioncash e58748fd80 core/memory: Migrate over address checking functions to the new Memory class
A fairly straightforward migration. These member functions can just be
mostly moved verbatim with minor changes. We already have the necessary
plumbing in places that they're used.

IsKernelVirtualAddress() can remain a non-member function, since it
doesn't rely on class state in any form.
2019-11-26 21:53:34 -05:00
Lioncash 323680e5ad core/memory: Migrate over memory mapping functions to the new Memory class
Migrates all of the direct mapping facilities over to the new memory
class. In the process, this also obsoletes the need for memory_setup.h,
so we can remove it entirely from the project.

Fernando Sahmkow 2d16507f9f Kernel: Correct behavior of Condition Variables to be more similar to real hardware.
This commit ensures cond var threads act exactly as they do in the real
console. The original implementation uses an RBTree and the behavior of
cond var threads is that at the same priority level they act like a
FIFO.

Lioncash 12dc918937 kernel: Resolve sign conversion warnings
Uncovered a bug within Thread's SetCoreAndAffinityMask() where an
unsigned variable (ideal_core) was being compared against "< 0", which
would always be a false condition.

We can also get rid of an unused function (GetNextProcessorId) which contained a sign
mismatch warning.
