f8be3f55da kernel/svc: Name supervisor call 0x36
This call was added to the SVC handlers in the 8.0.0 kernel, so we can
finally give it a name.

This doesn't actually modify internal state of a wait object, so it can

This member variable is entirely unused. It was only set but never
actually utilized. Given that, we can remove it to get rid of noise in

4d293bb5cb kernel/svc: Implement svcUnmapProcessCodeMemory
Essentially performs the inverse of svcMapProcessCodeMemory. This unmaps
the aliasing region first, then restores the general traits of the
aliased memory.

What this entails, is:

- Restoring Read/Write permissions to the VMA.
- Restoring its memory state to reflect it as a general heap memory region.
- Clearing the memory attributes on the region.

612e1388df core/core: Move process execution start to System's Load()
This gives us significantly more control over where in the
initialization process we start execution of the main process.

Previously we were running the main process before the CPU or GPU
threads were initialized (not good). This amends execution to start
after all of our threads are properly set up.

32a6ceb4e5 core/process: Remove unideal page table setting from LoadFromMetadata()
Initially required due to the split codepath with how the initial main
process instance was initialized. We used to initialize the process
like:

Init() {
    main_process = Process::Create(...);
    kernel.MakeCurrentProcess(main_process.get());
}

Load() {
    const auto load_result = loader.Load(*kernel.GetCurrentProcess());
    if (load_result != Loader::ResultStatus::Success) {
        // Handle error here.
    }
    ...
}

which presented a problem.

Setting a created process as the main process would set the page table
for that process as the main page table. This is fine... until we get to
the part that the page table can have its size changed in the Load()
function via NPDM metadata, which can dictate either a 32-bit, 36-bit,
or 39-bit usable address space.

Now that we have full control over the process' creation in load, we can
simply set the initial process as the main process after all the loading
is done, reflecting the potential page table changes without any
special-casing behavior.

We can also remove the cache flushing within LoadModule(), as execution
wouldn't have even begun yet during all usages of this function, now
that we have the initialization order cleaned up.

a4b0a8559c core/core: Move main process creation into Load()
Now that we have dependencies on the initialization order, we can move
the creation of the main process to a more sensible area: where we
actually load in the executable data.

This allows localizing the creation and loading of the process in one
location, making the initialization of the process much nicer to trace.

6d0551196d video_core/gpu: Create threads separately from initialization
Like with CPU emulation, we generally don't want to fire off the threads
immediately after the relevant classes are initialized, we want to do
this after all necessary data is done loading first.

This splits the thread creation into its own interface member function
to allow controlling when these threads in particular get created.

f2331a804a core/cpu_core_manager: Create threads separately from initialization.
Our initialization process is a little wonky than one would expect when
it comes to code flow. We initialize the CPU last, as opposed to
hardware, where the CPU obviously needs to be first, otherwise nothing
else would work, and we have code that adds checks to get around this.

For example, in the page table setting code, we check to see if the
system is turned on before we even notify the CPU instances of a page
table switch. This results in dead code (at the moment), because the
only time a page table switch will occur is when the system is *not*
running, preventing the emulated CPU instances from being notified of a
page table switch in a convenient manner (technically the code path
could be taken, but we don't emulate the process creation svc handlers
yet).

This moves the threads creation into its own member function of the core
manager and restores a little order (and predictability) to our
initialization process.

Previously, in the multi-threaded cases, we'd kick off several threads
before even the main kernel process was created and ready to execute (gross!).
Now the initialization process is like so:

Initialization:
  1. Timers

  2. CPU

  3. Kernel

  4. Filesystem stuff (kind of gross, but can be amended trivially)

  5. Applet stuff (ditto in terms of being kind of gross)

  6. Main process (will be moved into the loading step in a following
                   change)

  7. Telemetry (this should be initialized last in the future).

  8. Services (4 and 5 should ideally be alongside this).

  9. GDB (gross. Uses namespace scope state. Needs to be refactored into a
          class or booted altogether).

  10. Renderer

  11. GPU (will also have its threads created in a separate step in a
           following change).

Which... isn't *ideal* per-se, however getting rid of the wonky
intertwining of CPU state initialization out of this mix gets rid of
most of the footguns when it comes to our initialization process.

6300ccbc3c kernel: Make handle type declarations constexpr
Some objects declare their handle type as const, while others declare it
as constexpr. This makes the const ones constexpr for consistency, and
prevent unexpected compilation errors if these happen to be attempted to be
used within a constexpr context.

These indicate options that alter how a read/write is performed.

Currently we don't need to handle these, as the only one that seems to
be used is for writes, but all the custom options ever seem to do is
immediate flushing, which we already do by default.

2abf979c35 kernel/process: Set page table when page table resizes occur.
We need to ensure dynarmic gets a valid pointer if the page table is
resized (the relevant pointers would be invalidated in this scenario).

In this scenario, the page table can be resized depending on what kind
of address space is specified within the NPDM metadata (if it's
present).

b117ca5fce kernel/svc: Deglobalize the supervisor call handlers
Adjusts the interface of the wrappers to take a system reference, which
allows accessing a system instance without using the global accessors.

This also allows getting rid of all global accessors within the
supervisor call handling code. While this does make the wrappers
themselves slightly more noisy, this will be further cleaned up in a
follow-up. This eliminates the global system accessors in the current
code while preserving the existing interface.
