* Remove mapped dmem type
Since physical addresses can be mapped multiple times, tracking mapped pages is not necessary.
This also allows me to significantly simplify the MapMemory physical address validation logic.
* Proper implementation for sceKernelMtypeprotect
I've rewritten SetDirectMemoryType to use virtual addresses instead of physical addresses, allowing it to be used in sceKernelMtypeprotect.
To accommodate this change, I've also moved address and size alignment out of MemoryManager::Protect
* Apply memory type in sceKernelMemoryPoolCommit
* Organization
Some potentially important missing mutexes, removed some unnecessary mutexes, moved some mutexes after early error returns, and updated copyright dates
* Iterator logic cleanup
Missing end check in ClampRangeSize, and adjusted VirtualQuery and DirectMemoryQuery.
* Clang
* Adjustments
* Properly account for behavior differences in MapDirectMemory2
Undid the changes to direct memory areas, added more robust logic for changing dma types, and fixed DirectMemoryQuery to return hardware-accurate direct memory information in cases where dmas split here, but not on real hardware.
I've also changed MapMemory's is_exec flag to a validate_dmem flag, used to handle alternate behavior in MapDirectMemory2. is_exec is now determined by the use of MemoryProt::CpuExec instead.
* Clang
* Add execute permissions to physical backing
Needed for executable mappings to work properly on Windows, fixes regression in RE2 with prior commit.
* Minor variable cleanup
* Update memory.h
* Prohibit direct memory mappings with exec protections
Did a quick hardware test to confirm, only seems to be prohibited for dmem mappings though.
* Update memory.cpp
* Fix isDevKit
Previously, isDevKit could increase the physical memory used above the length we reserve in the backing file.
* Physical backing for flexible allocations
I took the simple approach here, creating a separate map for flexible allocations and pretty much just copying over the logic used in the direct memory map.
* Various fixups
* Fix mistake #1
* Assert + clang
* Fix 2
* Clang
* Fix CanMergeWith
Validate physical base for flexible mappings
* Clang
* Physical backing for pooled memory
* Allow VMA splitting in NameVirtualRange
This should be safe, since with the changes in this PR, the only issues that come from discrepancies between address space and vma_map are issues related to vmas being larger than address space mappings. NameVirtualRange will only ever shrink VMAs by naming part of one.
* Fix
* Fix NameVirtualRange
* Revert NameVirtualRange changes
Seems like it doesn't play nice for Windows
* Clean up isDevKit logic
We already log both isNeo and isDevKit in Emulator::Run, so the additional logging in MemoryManager::SetupMemoryRegions isn't really necessary.
I've also added a separate constant for non-pro devkit memory, as suggested.
Finally I've changed a couple constants to use the ORBIS prefix we generally follow here, instead of the SCE prefix.
* Erase flexible memory contents from physical memory on unmap
Flexible memory should not be preserved on unmap, so erase flexible contents from the physical backing when unmapping.
* Expand flexible memory map
Some games will end up fragmenting the physical backing space used for flexible memory. To reduce the frequency of this happening under normal circumstances, allocate the entirety of the remaining physical backing to the flexible memory map.
This is effectively a workaround to the problem, but at the moment I think this should suffice.
