25a5ce9e75 Kernel/SharedMemory: Don't take over and unmap the source memory block when creating a shared memory, just reference it. 
Also reference the right offset into the backing block for the requested address.

Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken

a0054d695e Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken. 
This change makes for a clearer (less confusing) path of execution in the scheduler, now the code to execute when a thread awakes is closer to the code that puts the thread to sleep (WaitSynch1, WaitSynchN). It also allows us to implement the special wake up behavior of ReplyAndReceive without hacking up WaitObject::WakeupAllWaitingThreads.

If savestates are desired in the future, we can change this implementation to one similar to the CoreTiming event system, where we first register the callback functions at startup and assign their identifiers to the Thread callback variable instead of directly assigning a lambda to the wake up callback variable.

2e78c05d91 Kernel/Thread: Allow specifying which process a thread belongs to when creating it. 
Don't automatically assume that Thread::Create will only be called when the parent process is currently scheduled. This assumption will be broken when applets or system modules are loaded.

9200465e55 Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process. 
We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.

71281c2114 Kernel/Memory: Changed GetPhysicalPointer so that it doesn't go through the current process' page table to obtain a pointer. 2017-09-15 14:26:13 -05:00

36100ec791 Kernel/Memory: Give each Process its own page table. 
The loader is in charge of setting the newly created process's page table as the main one during the loading process.

9cf64ca2cf Kernel/HLE: Use a mutex to synchronize access to the HLE kernel state between the cpu thread and any other possible threads that might touch the kernel (network thread, etc). 
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.

733dfe220e Kernel/Threads: Don't immediately switch to the new main thread when loading a new process. 
This is necessary for loading multiple processes at the same time.
The main thread will be automatically scheduled when necessary once the scheduler runs.

0a7f4f531f Service: Add new ServiceFramework framework for writing HLE services 
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.

8a35f3634e Kernel: Add a dedicated SetHleHandler method to ServerPort/ServerSession 
This allows attaching a HLE handle to a ServerPort at any point after it

regular services.
