Lioncash f785f73e92 general: Replace NonCopyable struct with equivalents 3 years ago
Markus Wick 3d2e80daed core/arm_interface: Call SVC after end of dynarmic block. 
So we can modify all of dynarmic states within SVC without ExceptionalExit.

Especially as the ExceptionalExit hack is dropped on upstream dynarmic.

Markus Wick 993dbe49fc core/arm: Drop ChangeProcessorID. 
This code was used to switch the CPU ID on thread switches.
However since "hle: kernel: multicore: Replace n-JITs impl. with 4 JITs.", the CPU ID is not a constant.
This has been dead code since this rewrite, and dropped in dynarmic as well. So there is no need to keep it.

Lioncash be1954e04c core: Fix clang build 
Recent changes to the build system that made more warnings be flagged as
errors caused building via clang to break.

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.

Lioncash 70624e1c1d core/arm: Remove obsolete Unicorn memory mapping 
This was initially necessary when AArch64 JIT emulation was in its
infancy and all memory-related instructions weren't implemented.

Given the JIT now has all of these facilities implemented, we can remove
these functions from the CPU interface.

Returns results as a vector of entries for further processing. Logs addresses, offsets, and mangled name.

Lioncash 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.

This function doesn't modify instance state, so it can be made const.

Lioncash 16145e2f21 arm_interface: Add missing fpsr/tpidr members to the ThreadContext struct 
Internally within the kernel, it also includes a member variable for the
floating-point status register, and TPIDR, so we should do the same here to match
it.

While we're at it, also fix up the size of the struct and add a static
assertion to ensure it always stays the correct size.

Lioncash 9b8fc2b689 arm_interface: Replace kernel vm_manager include with a forward declaration 
Avoids an unnecessary inclusion and also uncovers three places where
indirect inclusions were relied upon, which allows us to also resolve
those.

Lioncash b51e7e0288 arm_interface: Remove ARM11-isms from the CPU interface 
This modifies the CPU interface to more accurately match an
AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods
don't even make sense to keep around for this interface, as Adv Simd is
used, rather than the VFP in the primary execution state. This is
essentially a modernization change that should have occurred from the
get-go.
