Fernando Sahmkow 2d16507f9f Kernel: Correct behavior of Condition Variables to be more similar to real hardware.
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.

Lioncash 12dc918937 kernel: Resolve sign conversion warnings
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.

bunnei b0ab803ce8 kernel: events: Remove ResetType::Automatic.
- This does not actually seem to exist in the real kernel - games reset these automatically.

Lioncash f1382cf0e7 core: Remove Core::CurrentProcess()
This only encourages the use of the global system instance (which will
be phased out long-term). Instead, we use the direct system function
call directly to remove the appealing but discouraged short-hand.

Lioncash f763e23083 kernel/vm_manager: Correct doxygen comment parameter tags for MapPhysicalMemory/UnmapPhysicalMemory
Corrects the parameter names within the doxygen comments so that they
resolve properly.

Lioncash b0da7e4262 kernel/vm_manager: Move variables closer to usage spots in MapPhysicalMemory/UnmapPhysicalMemory
Narrows the scope of variables down to where they're only necessary.

Lioncash 96cc9a9279 kernel/vm_manager: Correct behavior in failure case of UnmapPhysicalMemory()
If an unmapping operation fails, we shouldn't be decrementing the amount
of memory mapped and returning that the operation was successful. We
should actually be returning the error code in this case.

Lioncash 56c6f767ae kernel/vm_manager: Reserve memory ahead of time for slow path in MergeAdjacentVMA
Avoids potentially expensive (depending on the size of the memory block)
allocations by reserving the necessary memory before performing both
insertions. This avoids scenarios where the second insert may cause a
reallocation to occur.

Lioncash a43ee8d752 kernel/vm_manager: std::move shared_ptr instance in MergeAdjacentVMA
Avoids an unnecessary atomic reference count increment and decrement.
2019-08-29 19:28:58 -04:00
Lioncash 785c4946dd kernel/vm_manager: Deduplicate iterator creation in MergeAdjacentVMA
Avoids needing to read the same long sequence of code in both code
paths. Also makes it slightly nicer to read and debug, as the locals
will be able to be shown in the debugger.

Lioncash 70485e690b kernel/vm_manager: Simplify some std::vector constructor calls

Lioncash 3f695333cd kernel/vm_manager: Simplify some assertion messages
Assertions already log out the function name, so there's no need to
manually include the function name in the assertion strings.

Fernando Sahmkow 9bede4eeed VM_Manager: Align allocated memory to 256bytes
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.
