Prior to PR, Yuzu did not restore memory to RW-
on unmap of mirrored memory or unloading of NRO.
(In fact, in the NRO case, the memory was unmapped
instead of reprotected to --- on Load, so it was
actually lost entirely...)
This PR addresses that, and restores memory to RW-
as it should.
This fixes a crash in Super Smash Bros when creating
a World of Light save for the first time, and possibly
other games/circumstances.
We don't have any friends implemented in Yuzu yet so it doesn't make sense to return any friends. For now we'll be returning 0 friends however the information provided will allow a proper implementation of this cmd when needed.
The event should only be signaled when an output audio device gets changed. Example, Speaker to USB headset. We don't identify different devices internally yet so there's no need to signal the event yet.
StartLrAssignmentMode and StopLrAssignmentMode don't require any implementation as it's just used for showing the screen of changing the controller orientation if the user wishes to do so. Ever since #1634 this has not been needed as users can specify the controller orientation from the config and swap at any time. We store a private member just in case this gets used for anything extra in the future
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
