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.

B3n30 813837c5cf Merge pull request #2842 from Subv/switchable_page_table 
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).
 2017-08-23 18:17:44 -06:00
bunnei 2bbff9fa96 Merge pull request #2893 from Subv/not_schedule_main_thread 
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.

 2017-06-08 00:33:24 -07:00
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
is created, allowing port/session creation to be generic between HLE and
regular services.
 2017-06-06 02:56:32 -07:00
Yuri Kunde Schlesner e626a520ca HLE: Move SessionRequestHandler from Service:: to Kernel:: 
Most of the code that works with this is or will be in the kernel, so
it's a more appropriate place for it to be.

Yuri Kunde Schlesner 64ecf81a3c Kernel: Move WaitObject to a separate file 
Now that HandleTable doesn't directly depend on WaitObject anymore, this
can be separated from the main kernel.h header.
 2017-05-29 16:16:46 -07:00
Yuri Kunde Schlesner 9453223075 Kernel: Removed HandleTable::GetWaitObject

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. 
With this we avoid an useless temporary deschedule of the current thread.

Subv 5e2a8ebabf Kernel: Remove some unused functions. 2017-01-05 13:17:06 -05:00
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. 
This fixes a potential bug where threads would not get removed from said list if they awoke after waiting with WaitSynchronizationN with wait_all = false
 2017-01-05 09:40:15 -05:00
Subv fd95b6ee26 Kernel: Remove Thread::wait_objects_index and use wait_objects to hold all the objects that a thread is waiting on. 2017-01-05 09:40:14 -05:00
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.
 2017-01-04 15:58:46 -05:00
Subv e6a7723f2f Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter. 
This will be useful when implementing mutex priority inheritance.

Subv bdad00c73f Threading: Added some utility functions and const correctness. 2016-12-04 09:58:36 -05:00
Subv 8634b8cb83 Threading: Reworked the way our scheduler works. 
Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then.

The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback.

This new implementation is based off reverse-engineering of the real kernel.

See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

Subv 009b15b3aa A bit of a redesign. 
Sessions and Ports are now detached from each other.
HLE services are handled by means of a SessionRequestHandler class, Interface now inherits from this class.
The File and Directory classes are no longer kernel objects, but SessionRequestHandlers instead, bound to a ServerSession when requested.
File::OpenLinkFile now creates a new session pair and binds the File instance to it.

Subv c5e7e0fa26 IPC/HLE: Associate the ClientSessions with their parent port's HLE interface if it exists.

 2016-11-30 23:04:00 -05:00
Subv c19afd2118 Kernel/HLE: Service::Interface no longer inherits from any Kernel object, and is now its own standalone class. 
Interface is now used by aggregation in ClientPort, to forward service commands to their HLE implementation if needed.
 2016-11-30 23:03:59 -05:00
Subv 0a33d915f8 fixup! Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication. 2016-11-30 23:02:06 -05:00
Subv 073653e858 Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication. 
All handles obtained via srv::GetServiceHandle or svcConnectToPort are references to ClientSessions.
Service modules will wait on the counterpart of those ClientSessions (Called ServerSessions) using svcReplyAndReceive or svcWaitSynchronization[1|N], and will be awoken when a SyncRequest is performed.

HLE Interfaces are now ClientPorts which override the HandleSyncRequest virtual member function to perform command handling immediately.

in turn held references to Process, causing CodeSets to never be freed
when loading other applications.

Other changes:
* Fixed comments in arm interfaces.
* Updated comments in thread.cpp
* Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp.
* Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.

Yuri Kunde Schlesner 52f58e64ef Kernel: Make WaitObjects share ownership of Threads waiting on them 
During normal operation, a thread waiting on an WaitObject and the
object hold mutual references to each other for the duration of the
wait.

If a process is forcefully terminated (The CTR kernel has a SVC to do
this, TerminateProcess, though no equivalent exists for threads.) its
threads would also be stopped and destroyed, leaving dangling pointers
in the WaitObjects.

The solution is to simply have the Thread remove itself from WaitObjects
when it is stopped. The vector of Threads in WaitObject has also been
changed to hold SharedPtrs, just in case. (Better to have a reference
cycle than a crash.)

Yuri Kunde Schlesner 7725256f64 Explicitly instantiate constructors/destructors for Kernel objects 
This should speed up compile times a bit, as well as enable more liberal
use of forward declarations. (Due to SharedPtr not trying to emit the
destructor anymore.)
