Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken
2017-09-30 09:12:18 -05:00
Huw Pascoe a13ab958cb Fixed type conversion ambiguity 2017-09-30 09:34:35 +01:00
Subv 8432749db7 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.
2017-09-28 11:53:32 -05:00
Subv 3165466b66 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.

Kernel/Memory: Give each process its own page table and allow switching the current page table upon reschedule
2017-09-15 22:41:45 +02:00
Subv b178089251 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.
2017-09-15 14:26:15 -05:00
Subv 214150f00c 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
Subv c34ec5e77c Kernel/Memory: Switch the current page table when a new process is scheduled. 2017-09-10 15:14:31 -05:00
Subv 6d2734a074 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.

James Rowe 61442d6afb Merge pull request #2839 from Subv/global_kernel_lock
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).

Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.
2017-08-22 17:45:47 -04:00
Subv bca8916cea 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.
2017-08-22 09:30:55 -05:00
Subv fa228ca637 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.

Yuri Kunde Schlesner 84c497292a 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.

Yuri Kunde Schlesner 6354d08359 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.

Yuri Kunde Schlesner f18d454eb6 Kernel: Map special regions according to ExHeader
This replaces the hardcoded VRAM/DSP mappings with ones made based on
the ExHeader ARM11 Kernel caps list. While this has no visible effect
for most applications (since they use a standard set of mappings) it
does improve support for system modules and n3DS exclusives.

Subv fc2266130b Kernel: Don't attempt to yield execution in SleepThread(0) if there are no available threads to run.

Subv 933df2606a Kernel: Removed the priority boost code for starved threads.
After hwtesting and reverse engineering the kernel, it was found that the CTROS scheduler performs no priority boosting for threads like this, although some other forms of scheduling priority-starved threads might take place.

For example, it was found that hardware interrupts might cause low-priority threads to run if the CPU is preempted in the middle of an SVC handler that deschedules the current (high priority) thread before scheduling it again.

Subv 7f1dca8cd2 Kernel: Remove a thread from all of its waiting objects' waiting_threads list when it is awoken.

Subv cef5f45de2 Kernel: Use different thread statuses when a thread calls WaitSynchronization1 and WaitSynchronizationN with wait_all = true.
This commit removes the overly general THREADSTATUS_WAIT_SYNCH and replaces it with two more granular statuses:

THREADSTATUS_WAIT_SYNCH_ANY when a thread waits on objects via WaitSynchronization1 or WaitSynchronizationN with wait_all = false.

THREADSTATUS_WAIT_SYNCH_ALL when a thread waits on objects via WaitSynchronizationN with wait_all = true.

Subv 7abf185390 Kernel/Mutex: Implemented priority inheritance.
The implementation is based on reverse engineering of the 3DS's kernel.

A mutex holder's priority will be temporarily boosted to the best priority among any threads that want to acquire any of its held mutexes.
When the holder releases the mutex, it's priority will be boosted to the best priority among the threads that want to acquire any of its remaining held mutexes.
