* 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 |
