This function is called rarely and blocks quite often for a long time.
So don't waste power and let the CPU sleep.
This might also increase the performance as the other cores might be allowed to clock higher.
* 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
* core_timing: Use better reference tracking for EventType.
- Moves ownership of the event to the caller, ensuring we don't fire events for destroyed objects.
- Removes need for unique names - we won't be using this for save states anyways.
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.
This commit corrects the behavior of cancel synchronization when the
thread is running/ready and ensures the next wait is cancelled as it's
suppose to.
Maintains implementation parity between QueryApplicationPlayStatistics
and QueryApplicationPlayStatisticsByUid.
These function the same behaviorally underneath the hood, with the only
difference being that one allows specifying a UID.
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.
- This does not actually seem to exist in the real kernel - games reset these automatically.

While not an issue, it does prevent fallthrough from occurring if
anything is ever added after this case (unlikely to occur, but this
turns a trivial "should not cause issues" into a definite "won't cause
issues).
While a map is an OK way to do lookups (and usually recommended in most
cases), this is a map that lives for the entire duration of the program
and only deallocates its contents when the program terminates.
Given the total size of the map is quite small, we can simply use a
std::array of pairs and utilize std::find_if to perform the same
behavior without loss of performance.
This eliminates a static constructor and places the data into the
read-only segment.
While we're at it, we can also handle malformed inputs instead of
directly dereferencing the resulting iterator.
In case of redundant yields, the scheduler will now idle the core for
it's timeslice, in order to avoid continuously yielding the same thing
over and over.
