Lioncash 0cbcd6ec9a kernel: Eliminate kernel global state
As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.

This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.

This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.

The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.

Lioncash bf45092c61 kernel: Move object class to its own source files
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.

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).

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.

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.

Yuri Kunde Schlesner 9453223075 Kernel: Removed HandleTable::GetWaitObject

WaitObjects.

Subv b6a0355568 Kernel/Mutex: Update a mutex priority when a thread stops waiting on it. 2017-01-04 15:58:47 -05:00
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.

Subv e6a7723f2f Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter.

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.

Subv 29d809b6e1 Kernel: Remove the Redirection handle type. 2016-12-05 11:13:22 -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 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.

Subv 1323ab2f5f Kernel/Loader: Grab the system mode from the NCCH ExHeader.
3dsx and elf files default to system mode 2 (96MB allocated to the application).

This allows Home Menu to boot without modifications.

This makes clang-format useful on those.

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

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.
