* Back to the origins: Make memory manager take guest PA rather than host address once again * Direct mapping with alias support on Windows * Fixes and remove more of the emulated shared memory * Linux support * Make shared and transfer memory not depend on SharedMemoryStorage * More efficient view mapping on Windows (no more restricted to 4KB pages at a time) * Handle potential access violations caused by partial unmap * Implement host mapping using shared memory on Linux * Add new GetPhysicalAddressChecked method, used to ensure the virtual address is mapped before address translation Also align GetRef behaviour with software memory manager * We don't need a mirrorable memory block for software memory manager mode * Disable memory aliasing tests while we don't have shared memory support on Mac * Shared memory & SIGBUS handler for macOS * Fix typo + nits + re-enable memory tests * Set MAP_JIT_DARWIN on x86 Mac too * Add back the address space mirror * Only set MAP_JIT_DARWIN if we are mapping as executable * Disable aliasing tests again (still fails on Mac) * Fix UnmapView4KB (by not casting size to int) * Use ref counting on memory blocks to delay closing the shared memory handle until all blocks using it are disposed * Address PR feedback * Make RO hold a reference to the guest process memory manager to avoid early disposal Co-authored-by: nastys <nastys@users.noreply.github.com>
