This will be necessary for making our TLS slot management slightly more
straightforward. This can also be utilized for other purposes in the
future.
We can implement the existing simpler overload in terms of this one
anyways, we just pass the beginning and end of the ASLR region as the
boundaries.
InitializeApplicationInfoRestricted will need further implementation as it's checking for other user requirements about the game. As we're emulating, we're assuming the user owns the game so we skip these checks currently, implementation will need to be added further on
This PR attempts to implement the shared memory provided by GetSharedMemoryNativeHandle. There is still more work to be done however that requires a rehaul of the current time module to handle clock contexts. This PR is mainly to get the basic functionality of the SharedMemory working and allow the use of addition to it whilst things get improved on.
Things to note:
Memory Barriers are used in the SharedMemory and a better solution would need to be done to implement this. Currently in this PR I’m faking the memory barriers as everything is sync and single threaded. They work by incrementing the counter and just populate the two data slots. On data reading, it will read the last added data.
Specific values in the shared memory would need to be updated periodically. This isn't included in this PR since we don't actively do this yet. In a later PR when time is refactored this should be done.
Finally, as we don't handle clock contexts. When time is refactored, we will need to update the shared memory for specific contexts. This PR does this already however since the contexts are all identical and not separated. We're just updating the same values for each context which in this case is empty.
Tiime:SetStandardUserSystemClockAutomaticCorrectionEnabled, Time:IsStandardUserSystemClockAutomaticCorrectionEnabled are also partially implemented in this PR. The reason the implementation is partial is because once again, a lack of clock contexts. This will be improved on in a future PR.
This PR closes issue #2556
Even though it has been proven that IAudioRenderer:SystemEvent is
actually an automatic event. The current implementation of such event is
all thought to be manual. Thus it's implementation needs to be corrected
when doing such change. As it is right now this PR introduced a series
of regressions on softlocks on multiple games. Therefore, this pr
reverts such change until a correct implementation is made.
The old implementation had faulty Threadsafe methods where events could
be missing. This implementation unifies unsafe/safe methods and makes
core timing thread safe overall.
IPC-100 was changed to InitializeApplicationInfoOld instead of InitializeApplicationInfo. IPC-150 makes an indentical call to IPC-100 however does extra processing. They should not have the same name as it's quite confusing to debug.
These can be generified together by using a concept type to designate
them. This also has the benefit of not making copies of potentially very
large arrays.
This is performing more work than would otherwise be necessary during
VMManager's destruction. All we actually want to occur in this scenario
is for any allocated memory to be freed, which will happen automatically
as the VMManager instance goes out of scope.
Anything else being done is simply unnecessary work.
Given we don't currently implement the personal heap yet, the existing
memory querying functions are essentially doing what the memory querying
types introduced in 6.0.0 do.
So, we can build the necessary machinery over the top of those and just
use them as part of info types.
