kernel: Remove old VMManager class.

2020-04-17T04:59:35+00:00

kernel: transfer_memory: Properly reserve and reset memory region.

2020-02-06T04:06:54+00:00

core/memory: Create a special MapMemoryRegion for physical memory.

2020-01-18T07:38:47+00:00

This allows us to create a fastmem arena within the memory.cpp helpers.

core/hle: Simplify PhysicalMemory usage in vm_manager.

2020-01-18T07:29:19+00:00

core/memory: Migrate over memory mapping functions to the new Memory class

2019-11-27T02:53:34+00:00

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.

kernel: Resolve sign conversion warnings

2019-11-12T12:55:39+00:00

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.

kernel/vm_manager: Move variables closer to usage spots in MapPhysicalMemory/UnmapPhysicalMemory

2019-09-04T23:58:52+00:00

Narrows the scope of variables down to where they're only necessary.

kernel/vm_manager: Correct behavior in failure case of UnmapPhysicalMemory()

2019-08-29T23:29:43+00:00

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.

kernel/vm_manager: Reserve memory ahead of time for slow path in MergeAdjacentVMA

2019-08-29T23:29:43+00:00

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.

kernel/vm_manager: std::move shared_ptr instance in MergeAdjacentVMA

2019-08-29T23:28:58+00:00

Avoids an unnecessary atomic reference count increment and decrement.
