Lioncash 77356731a9 hle_ipc: Remove std::size_t casts where applicable
These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.

Now that the flags are enabled, we can freely change the interface to
make these unnecessary.

Lioncash 1c340c6efa CMakeLists: Specify -Wextra on linux builds
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.

We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).

While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.

Lioncash 213fff67bc CMakeLists: Make -Wreorder a compile-time error

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

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

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.

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.

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.

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.

Lioncash 323680e5ad core/memory: Migrate over memory mapping functions to the new Memory class

so we can remove it entirely from the project.
