bunnei abc079aca1 hle: kernel: physical_core: Clear exclusive state after each run. 
- This is closer to pre-multicore behavior, and works a bit better.

Lioncash b038dcf23c svc: Remove unnecessary [[maybe_unused]] tag 
The parameter is used in this function, so this suppression isn't
necessary.

Lioncash e7fe020ace ipc_helpers: Remove usage of the global system instance 
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

Lioncash 5c55f3b585 core: Remove usage of unicorn 
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

ReinUsesLisp 1a1ca86eb5 hle/kernel: Remove unused registered_core_threads to fix data races 
This member was only used on asserts and it triggered data races.
Remove it to fix them.

lat9nq 2974d72a2a kernel: Use the current time as the default RNG seed

Lioncash 1367e8fb75 kernel: Fix build with recent compiler flag changes 
This slipped through the cracks due to another change being merged
before the compiler flag changes.

Lioncash 18636013c9 core: Fix clang build 
Recent changes to the build system that made more warnings be flagged as
errors caused building via clang to break.

Fixes #4795

ReinUsesLisp a13623c68b kernel: Implement host thread register methods without locking 
Locks on GetCurrentHostThreadID were causing performance issues
according to Visual Studio's profiler. It was consuming twice the time
as arm_interface.Run(). The cost was not in the function itself but in
the lockinig it required.

Reimplement these functions using atomics and static storage instead of
an unordered_map. This is a side effect to avoid locking and using linked
lists for reads.

Replace unordered_map with a linear search.

Lioncash 16de0a6a96 core/CMakeLists: Make some warnings errors 
Makes our error coverage a little more consistent across the board by
applying it to Linux side of things as well. This also makes it more
consistent with the warning settings in other libraries in the project.

This also updates httplib to 0.7.9, as there are several warning
cleanups made that allow us to enable several warnings as errors.

Lioncash f700c48cc0 kernel: Remove all dependencies on the global system instance 
With this, the kernel finally doesn't depend directly on the global
system instance anymore.

bunnei 7b536a07f2 Merge pull request #4323 from ReinUsesLisp/no-spin 
kernel/scheduler: Use std::mutex instead of spin lock

bunnei 2af4f1ac07 Merge pull request #4590 from ReinUsesLisp/tsan-sched 
hle/scheduler: Fix data race in is_context_switch_pending
 2020-09-03 14:39:57 -04:00
ReinUsesLisp 8f050dd1d9 hle/scheduler: Fix data race in is_context_switch_pending 
As reported by tsan, SelectThreads could write to
is_context_switch_pending holding a mutex while SwitchToCurrent reads it
without holding any.

It is assumed that the author didn't want an atomic here, so the code is
reordered so that whenever is_context_switch_pending is read inside
SwitchToContext, the mutex is locked.
