Subv 38a90882a4 Kernel/Synch: Do not attempt a reschedule on every syscall. 
Not all syscalls should cause reschedules, this commit attempts to remedy that, however, it still does not cover all cases.

Subv 406907d570 Properly remove a thread from its wait_objects' waitlist when it is awoken by a timeout. 2016-12-10 13:29:31 -05:00
Subv 17b29d8865 WaitSynch: Removed unused variables and reduced SharedPtr copies. 
Define a variable with the value of the sync timeout error code.

Use a boost::flat_map instead of an unordered_map to hold the equivalence of objects and wait indices in a WaitSynchN call.
 2016-12-09 12:23:09 -05:00
Subv f9bcf89510 Use std::move where appropriate. 2016-12-08 11:06:19 -05:00
Subv c93c5a72bb Return an error code when connecting to a saturated port. 
The error code was taken from the 3DS kernel.
 2016-12-05 13:59:57 -05:00
Subv dd8887c8cf KServerPorts now have an HLE handler "template", which is inherited by all ServerSessions created from it. 2016-12-05 11:02:08 -05:00
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 ed210c32b3 Threads do not wait for the server endpoint to call AcceptSession before returning from a ConnectToPort or GetServiceHandle call. 2016-12-01 10:47:06 -05:00
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.
 2016-11-30 23:12:35 -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.

Emmanuel Gil Peyrot ebdae19fd2 Remove empty newlines in #include blocks. 
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Subv 1bd0cf542f Kernel/SharedMemory: Properly implemented shared memory support. 
Applications can request the kernel to allocate a piece of the linear heap for them when creating a shared memory object.
Shared memory areas are now properly mapped into the target processes when calling svcMapMemoryBlock.

Removed the APT Shared Font hack as it is no longer needed.

Yuri Kunde Schlesner 18c1c39d5e SVC: Advance time when calling GetSystemTick to escape busy-wait loops 
Cubic Ninja waited for the frame to end by spinning on a loop calling
GetSystemTick while doing nothing else. Since GetSystemTick doesn't
cause a reschedule (which advances time), this meant that very little
emulated time would pass inside that loop, causing the game to spend
most of the frame burning away CPU.

Yuri Kunde Schlesner 0fcabd2b11 Integrate the MicroProfile profiling library 
This brings goodies such as a configurable user interface and

Yuri Kunde Schlesner 74d4bc0af1 Kernel: Add more infrastructure to support different memory layouts

Subv d3634d4bf4 Core/ResourceLimits: Implemented the basic structure of ResourceLimits. 
Implemented svcs GetResourceLimit, GetResourceLimitCurrentValues and GetResourceLimitLimitValues.

Note that the resource limits do not currently keep track of used objects, since we have no way to distinguish between an object created by the application, and an object created by some HLE module once we're inside Kernel::T::Create.

 2015-03-16 12:18:37 -04:00
archshift ef24e72b26 Asserts: break/crash program, fit to style guide; log.h->assert.h 
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

Kevin Hartman 5fcbfc06eb Scheduler refactor Pt. 1 
* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid
for a thread at any given point in the system.
* Removes dead code from thread.cpp.
* Moves the implementation of resetting a ThreadContext to the corresponding core's implementation.

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.
