This mutex is acquired in SVC::CallSVC, ie, as soon as the guest application enters the HLE kernel, and should be acquired by the aforementioned threads before modifying kernel structures.
It behaves mostly as WaitSynchronizationN with wait_all = false, except for IPC buffer translation.
The target thread of an IPC response will now wake up when responding.
IPC buffer translation is currently not implemented.
Error passing back to svcSendSyncRequest is currently not implemented.
Unmapping pages tries to flush any cached GPU surfaces touching that
region. When a cached page is invalidated, GetPointerFromVMA() is used
to restore the original pagetable pointer. However, since that VMA has
already been deleted, this hits an UNREACHABLE case in that function.
Now when this happens, just set the page type to Unmapped and continue,
which arrives at the correct end result.
* Services/UDS: Set the proper bit in the ConnectionStatus structure when creating a network.
This lets the application know that the host was successfully added to the session.
* Services/UDS: Reset the connection status when destroying the network
* Services/UDS: Reset the connection status's bitmask of changed nodes after reporting it to the game.
Copy the IPC command buffer to/from the request context before/after the
handler is invoked. This is part of a move away from using global data
for handling IPC requests.
The old "Interface" class had a few problems such as using free
functions (Which didn't allow you to write the service handler as if it
were a regular class.) which weren't very extensible. (Only received one
parameter with a pointer to the Interface object.)
The new ServiceFramework aims to solve these problems by working with
member functions and passing a generic context struct as parameter. This
struct can be extended in the future without having to update all
existing service implementations.
