In addition object ref-counts and support for DuplicateHandle have been added. Note that support for DuplicateHandle is still experimental, since parts of the kernel still use Handles internally, which will likely cause troubles if two different handles to the same object are used to e.g. wait on a synchronization primitive. --- src/core/hle/kernel/address_arbiter.cpp | 3 +- src/core/hle/kernel/event.cpp | 3 +- src/core/hle/kernel/kernel.cpp | 118 +++++++++++--------- src/core/hle/kernel/kernel.h | 190 ++++++++++++++++++-------------- src/core/hle/kernel/mutex.cpp | 5 +- src/core/hle/kernel/semaphore.cpp | 3 +- src/core/hle/kernel/shared_memory.cpp | 3 +- src/core/hle/kernel/thread.cpp | 3 +- src/core/hle/kernel/thread.h | 3 - src/core/hle/service/fs/archive.cpp | 10 +- src/core/hle/service/service.cpp | 3 +- src/core/hle/service/service.h | 5 +- src/core/hle/svc.cpp | 28 ++--- 13 files changed, 209 insertions(+), 168 deletions(-) (limited to 'src/core/hle') diff --git a/src/core/hle/kernel/address_arbiter.cpp b/src/core/hle/kernel/address_arbiter.cpp index acdbc92b3..38705e3cd 100644 --- a/src/core/hle/kernel/address_arbiter.cpp +++ b/src/core/hle/kernel/address_arbiter.cpp @@ -62,7 +62,8 @@ ResultCode ArbitrateAddress(Handle handle, ArbitrationType type, u32 address, s3 /// Create an address arbiter AddressArbiter* CreateAddressArbiter(Handle& handle, const std::string& name) { AddressArbiter* address_arbiter = new AddressArbiter;
